    ABSTRACT: The seed is the carrier of the genetic improvements brought about by modern plant breeding, and seed production is carried out in accordance with certification systems to guarantee consistent high quality. In forage legumes, breeding efforts are primarily related to the vegetative development of the plant, although the commercial success of an agronomically superior cultivar is dependent on a reliable supply of competitively priced seed. In seed production of the three most important forage legumes, alfalfa (Medicago sativa L.), white clover (Trifolium repens L.), and red clover (Trifolium pratense L.), crop management techniques are applied to stimulate reproductive development in order to obtain high seed yields. These include a low plant density, manipulation of canopy size to avoid lodging and shading of fruiting organs, synchronization of flowering with pollinating insects as well as controlling pests. High seed yield is correlated to inflorescence density and seed yield per inflorescence, traits which should be selected for in breeding populations as moderate to high heritability has been found. However, seed yield is a genetically complex trait and in the perennial, insect-pollinated forage legumes it is further highly influenced by environmental conditions and crop management factors. Further investigations into the use of plant growth regulators and an improved understanding of the interaction between pollinators and the seed crop might improve future seed yields. There is likely to be an increasing emphasis on the role of forage legumes in producing high-quality meat and milk, combined with the requirement to reduce the environmental footprint of grassland agriculture. A high forage legume seed yield is a prerequisite to meet market requirements for new, improved cultivars and hence achieve the economic impacts of modern plant breeding for a better livelihood and environment.

    ABSTRACT: The seeds of the plants of the Fabaceae, commonly known as “grain legumes” or “pulses,” are major foodstuffs in most countries. In addition, these seeds may also provide some health benefits, in particular in the area of hypercholesterolemia and hypertension prevention. Whereas the hypocholesterolemic activity of soy protein has been well known for decades and was finally supported by the health claim by the U.S. Food and Drug Administration in 1999, similar information on non-soy legumes is scarce. This paper reviews all such available data from animal models and human trials as well as information on the mechanism of action provided by in vitro studies, mainly on cell cultures or assays on specific enzymes. This body of data indicates that a regular consumption of grain legumes may be useful both for the prevention of hypercholesterolemia and hypertension. More investigations are needed, however, for elucidating the mechanism of action and the actual effective components in legumes.

    ABSTRACT: Recent advances in genomics and associated disciplines like bioinformatics have made it possible to develop genomic resources, such as large-scale sequence data for any crop species. While these datasets have been proven very useful for the understanding of genome architecture and dynamics as well as facilitating the discovery of genes, an obligation for, and challenge to the scientific community is to translate genome information to develop products, i.e. superior lines for trait(s) of interest. We call this approach, “translational genomics in agriculture” (TGA). TGA is currently in practice for cereal crops, such as maize (Zea mays) and rice (Oryza sativa), mainly in developed countries and by the private sector; progress has been slow for legume crops. Grown globally on 62.8 million ha with a production of 53.2 million tons and a value of nearly 24.2 billion dollars, the majority of these legumes have low crop productivity (Cicer arietinum), common bean (Phaseolus vulgaris), groundnut (Arachis hypogaea), pigeonpea (Cajanus cajan) and soybean (Glycine max). Some efforts have also been outlined to initiate/ accelerate TGA in three additional legume crops namely faba bean (Vicia faba), lentil (Lens culinaris) and pea (Pisum sativum).

    ABSTRACT: Arbuscular mycorrhiza (AM), ectomycorrhiza (ECM) and nitrogen (N) fixation through rhizobia symbioses (RS) play a critical role for plant nutrient use efficiency in natural ecosystems, usually characterized by nutrient limitation, especially regarding nitrogen and phosphate. Substantial evidence has accumulated about how the rational use of microsymbionts’ properties should significantly contribute to decreasing fertilizer and pesticide use in agriculture and forestry. Understanding the mechanisms underlying high N use efficiency by mycorrhizal/rhizobial plants and carbon allocation in a context of mutualistic biotrophic interactions is critical for managing both croplands and forests while taking care of the ecosystem services rendered by microbial symbionts. Availability, uptake and exchange of nutrients in biotrophic interactions drive plant growth and modulate biomass allocation, and these parameters are central to plant yield, a major outcome in the context of high biomass production. To unravel the symbiotic N “transportome” blueprint from various host plant combinations, it is critical to facilitate the first steps favoring the manipulation of crops toward greater nitrogen use efficiency and mycorrhizal or rhizobial ability. The present review addresses current knowledge on inorganic N transport in mycorrhizal/rhizobial symbiosis.

    ABSTRACT: Legumes form a large group of plants that constitute the third largest family of angiosperms, including near 20,000 species and 750 genera. Most of them have the ability to establish symbioses with diazotrophic bacteria, collectively known as rhizobia, which induce root nodules where biological nitrogen fixation takes place, conferring legumes a relevant ecological advantage. This group of bacteria that for many years was thought to be formed by a scarce number of genera and species within alpha proteobacteria, shows nowadays an important genetic diversity including species phylogenetically divergent both in core and symbiotic genes sequences. Together with rhizobia, other endophytic bacteria are present in legume nodules coexisting with rhizobial strains and their ecological role remains unknown in most cases, but they likely have an effect in plant health, plant growth or even in the rhizobia-legume symbiosis. In this review we present an overview of the associations of bacteria with legumes, the current available knowledge on the phylogenetic diversity of both rhizobia and endophytic bacteria inhabiting root nodules, and the symbiotic features used to define symbiovars in rhizobia.

    ABSTRACT: Although yield and total biomass produced by annual legumes remain major objectives for breeders, other issues such as environment-friendly, resource use efficiency including symbiotic performance, resilient production in the context of climate change, adaptation to sustainable cropping systems (reducing leaching, greenhouse gas emissions and pesticide residues), adaptation to diverse uses (seeds for feed, food, non-food, forage or green manure) and finally new ecological services such as pollinator protection, imply the need for definition of new ideotypes and development of innovative genotypes to enhance their commercialization. Taken as a whole, this means more complex and integrated objectives for breeders. Several illustrations will be given of breeding such complex traits for different annual legume species. Genetic diversity for root development and for the ability to establish efficient symbioses with rhizobia and mycorrhiza can contribute to better resource management (N, P, water). Shoot architectures and phenologies can contribute to yield and biotic constraint protection (parasitic weeds, diseases or insects) reducing pesticide use. Variable maturity periods and tolerance to biotic and abiotic stresses are key features for the introduction of annual legumes to low input cropping systems and for enlarging cultivated area. Adaptation to intercropping requires adapted genotypes. Improved health and nutritional value for humans are key objectives for developing new markets. Modifying product composition often requires the development of specific cultivars and sometimes the need to break negative genetic correlations with yield. A holistic approach in legume breeding is important for defining objectives with farmers, processors and consumers. The cultivar structures are likely to be more complex, combining genotypes, plant species and associated symbionts. New tools to build and evaluate them are important if legumes are to deliver their exciting potential in terms of agricultural productivity and sustainability as well as for feed and food.

    ABSTRACT: Quality aspects of food crops have globally important market economic and health repercussions in the current climate of food security. Grain legumes have high potential for the nutritional quality improvement of foods, but limited data on manipulating seed quality is available as the primary focus has been hitherto on phenotypic and agronomic trait improvement. This has resulted in a lack of innovation and low attractiveness of legume food products that, with the emergence of novel food habits, have together contributed to reduced legume food consumption. This trend now needs to be challenged and circumvented. In this review we have assessed the key factors affecting the nutritional quality of legume seeds such as protein, starch, dietary fiber, natural antioxidant compounds and anti-nutritional factors. All have been reviewed with emphasis on how these components might influence consumer acceptance and functional properties of legume based food products. Biofortification approaches and technological processing are discussed as ways in which the nutritional value of legumes and their consumption might be enhanced. In order to increase consumption of grain legumes, we propose that efforts should concentrate on identifying nutritionally enhanced and genetically diverse germplasm, and on linking genetics with sensorial and processing quality. This will assist the development of breeding/selection tools for traits that determine consumer demand, facilitating the implementation of quality breeding objectives in legume breeding programs. Equally important, efforts should focus on developing attractive, convenient ready-to-eat and tasty legume-based food formulations, contributing to the diversification of healthier and more nutritional diets. As a result of such a targeted effort, legume cultivation and consumption could be enhanced leading to a reduction in both the global economic burden caused by malnutrition and associated chronic diseases, and the environmental impact of agriculture.

    ABSTRACT: Glyoxalases are known to play a very important role in abiotic stress tolerance. This two-step pathway detoxifies ubiquitously present cytotoxic metabolite methylglyoxal, which otherwise increases to lethal concentrations under various stress conditions. Methylglyoxal initiates stress-induced signaling cascade via reactive oxygen species, resulting in the modifications of proteins involved in various signal transduction pathways, that eventually culminates in cell death or growth arrest. The associated mechanism of tolerance conferred by over-expression of methylglyoxal-detoxifying glyoxalase pathway mainly involves lowering of methylglyoxal levels, thereby reducing subsequently induced cellular toxicity. Apart from abiotic stresses, expression of glyoxalases is affected by a wide variety of other stimuli such as biotic, chemical and hormonal treatments. Additionally, alterations in cellular milieu during plant growth and development also affect expression of glyoxalases. The multiple stress-inducible nature of these enzymes suggests a vital role for glyoxalases, associating them with plant defense mechanisms. In this context, we have summarized available transcriptome, proteome and genetic engineering- based reports in order to highlight the involvement of glyoxalases as important components of plant stress response. The role of methylglyoxal as signaling molecule is also discussed. Further, we examine the suitability of glyoxalases and methylglyoxal as potential markers for stress tolerance.

    ABSTRACT: Successful reproduction of flowering plants requires the appropriate timing of the floral transition, as triggered by environmental and internal cues and as regulated by multiple signaling modules. Among these modules, microRNAs (miRNAs), the evolutionarily conserved regulators, respond to environmental and internal cues and network with other integrators of flowering cues. Moreover, miRNA signaling modules affect the timing of flowering in many plant species. Here, we comprehensively review recent progress in understanding the function of miRNAs and their target genes in flowering time regulation in diverse plant species. We focus on the role of the miRNA-target gene modules in various flowering pathways and their conserved and divergent functions in flowering plants. We also examine, in depth, the crosstalk by sequential activity of miR156 and miR172, two of the most-studied and evolutionarily conserved miRNAs in both annual and perennial plants.

    ABSTRACT: The initial event in plant floral organogenesis is bract specification, followed by floral meristem (FM) initiation in bract axils, but initiation signals and the interplay between both lateral organs remain unelucidated. Floral organs are initiated on the flanks of the outgrowing FM and the enormous diversity in floral morphology throughout the plant kingdom reflects variations in organ position, meristy and ontogeny. Classical models of floral development have focused on Arabidopsis, which has mostly actinomorphic flowers, and Antirrhinum, which exhibits zygomorphy, although neither species is typical or representative of angiosperm flower diversity. Although the ABCE model defines a centripetal model of organ identity establishment in different whorls, the characterization of floral organ initiation in many species has relied on their morphological appearance, due to a lack of founder cell-specific markers. Recent progress in early Arabidopsis floral development using histology, molecular markers and mutants has led to refinements of existing floral organ initiation paradigms. In Arabidopsis, sepals initiate unidirectionally, in a temporal window characterized by the absence of CLAVATA3 and WUSCHEL stem cell markers and are partly dependent on PRESSED FLOWER function, whereas initiation of inner-whorl organs occurs centripetally. Arabidopsis mutants reveal that the FM is highly polarized along an ab-/adaxial axis and a comparison of floral development in Arabidopsis and Antirrhinum suggests that heterochrony of conserved gene functions has been evolutionarily adaptive.This review discusses current views on FM and organ specification signals, the gene regulatory networks that underlie floral meristem polarity, and analogies between the development of floral and leaf primordia as lateral organs. Alternative stem-cell proliferation mechanisms and the bifurcation of founder cell populations can help to explain the diversity in floral diversity throughout the plant kingdom and underpin comparative evolutionary biology and macroevolution. An analysis of plants with divergent body plans at the level of organ specification is urgently needed.

    ABSTRACT: From the soil, plants take up macronutrients (calcium, magnesium, nitrogen, phosphorus, potassium, sulfur) and micronutrients (boron, chloride, cobalt, copper, iron, manganese, molybdenum, nickel, selenium, and zinc). In acidic soils, aluminum can interfere with nutrient uptake. There is a need for improved diagnostic tests for these soil-derived minerals that are inexpensive and sensitive, provide spatial and temporal information in plants and soil, and report bioavailable nutrient pools. A transgenic whole-cell biosensor detects a stimulus inside or outside a cell and causes a change in expression of a visible reporter such as green fluorescent protein, and thus can convert an invisible plant nutrient into a visible signal. Common transgenic whole-cell biosensors consist of promoter-reporter fusions, auxotrophs for target analytes that are transformed with constitutively expressed reporters, riboswitches and reporters based on Forster Resonance Energy Transfer (FRET). Here, we review transgenic plant biosensors that have been used to detect macronutrients and micronutrients. As plant-based biosensors are limited by the requirement to introduce and optimize a transgene in every genotype of interest, we also review microbial biosensor cells that have been used to measure plant or soil nutrients by co-inoculation with their respective extracts. Additionally, we review published transgenic whole-cell biosensors from other disciplines that have the potential to measure plant nutrients, with the goal of stimulating the development of these diagnostic technologies. We discuss current limitations and future improvements needed, and the long-term potential of transgenic whole-cell biosensors to inform plant physiology, improve soil nutrient management, and assist in breeding crops with improved nutrient use efficiency.
