    ABSTRACT: The heterostylous reproductive system of Oxalis alpina in the Galiuro Mts. of Arizona was investigated using field surveys, controlled crosses in the greenhouse, and measurements of reproductive morphs. Although populations in the Pinaleño Mts. to the immediate east and in the Santa Catalina Mts. to the immediate west have derived distylous reproductive systems, tristyly, the ancestral reproductive system in O. alpina, has been retained in the Galiuro Mts. Tristylous incompatibility relationships in the Galiuro population are significantly modified from the ancestral condition, with significant loss of incompatibility differentiation between stamen whorls of both short- and long-styled morphs. Morphological adjustments of anther positions in the Galiuro population of O. alpina match those expected in light of incompatibility modification, with divergence of the mid-level anthers away from the position of the mid stigmas of the mid-styled morph. The occurrence of tristyly in an area of Arizona where distyly is found in adjacent mountain ranges is particularly remarkable, and indicates both the isolation of populations restricted to the upper elevations of these mountain ranges and variation in the tempo of evolution over short geographic distances.

    ABSTRACT: Potato is major crop for food security in Europe and blackleg disease is increasingly causing losses in its yield and storage. Recently, one of the blackleg pathogens, Dickeya solani has been shown to be spreading in northern Europe and that it causes an aggressive disease development. Currently, identification of tolerant commercial potato varieties has proven unsuccessful; this is confounded by a complicated etiology of the disease and a strong environmental influence on disease development. There is a lack in availability of efficient testing systems. Here, we describe a system for quantification of blackleg symptoms on shoots of sterile in vitro potato plants, that saves time and space compared to greenhouse and existing field assays. We found no evidence for differences in infection between the described in vitro based screening method and existing green-house assays. This system facilitates efficient screening of blackleg disease response of potato plants independent of other microorganisms and variable environmental conditions. We therefore used the in vitro screening method to increase understanding of plant mechanisms involved in blackleg disease development by analyzing disease response of hormone (salicylic and jasmonic acid) related transgenic potato plants. We show that both jasmonic (JA) and salicylic acid (SA) pathways regulate tolerance against blackleg disease in potato, a result that is different from previous findings in Arabidopsis defense response to necrotrophic bacteria. We confirm this by showing induction of a SA marker, pathogenesis related protein 1 (StPR1) and a JA marker, lipoxygenase (StLOX) in Dickeya solani infected in vitro potato plants. We also observed that tubers of hormone related transgenic potato plants were more susceptible to soft rot compared to wild-type suggesting a role for SA and JA pathways in general tolerance to Dickeya disease.This article is protected by copyright.

    ABSTRACT: Sexual dimorphism in resource allocation is expected to change during the life cycle of dioecious plants because of temporal differences between the sexes in reproductive investment. Given the potential for sex-specific differences in reproductive costs, resource availability may contribute to variation in reproductive allocation in females and males. Here, we used Rumex hastatulus, a dioecious, wind-pollinated, annual plant, to investigate whether sexual dimorphism varies with life-history stage and nutrient availability, and determine whether allocation patterns differ depending on reproductive commitment. To examine if the costs of reproduction varied between the sexes, reproduction was either allowed or prevented by bud removal, and biomass allocation was measured at maturity. In a second experiment to assess variation in sexual dimorphism across the life cycle, and whether this varied with resource availability, plants were grown in high and low nutrients and allocation to roots, above-ground vegetative growth and reproduction were measured at three developmental stages. Males prevented from reproducing compensated with increased above- and below-ground allocation to a much greater degree than females, suggesting that male reproductive costs reduce vegetative growth. The proportional allocation to roots, reproductive structures and above-ground vegetative growth varied between the sexes and among life-cycle stages, but not with nutrient treatment. Females allocated proportionally more resources to roots than males at peak flowering, but this pattern was reversed at reproductive maturity under low-nutrient conditions. Our study illustrates the importance of temporal dynamics in sex-specific resource allocation and provides support for high male reproductive costs in wind-pollinated plants.

    ABSTRACT: Developing fragrant rice through marker-assisted/aided selection (MAS) is an economical and profitable approach worldwide for the enrichment of an elite genetic background with a pleasant aroma. The PCR-based DNA markers that distinguish the alleles of major fragrance genes in rice have been synthesized to develop rice scent biofortification through MAS. Thus, the present study examined the aroma biofortification potential of these co-dominant markers in a germplasm panel of 189 F2 progenies developed from crosses between a non-aromatic variety (MR84) and a highly aromatic but low-yielding variety (MRQ74) to determine the most influential diagnostic markers for fragrance biofortification. The SSRs and functional DNA markers RM5633 (on chromosome 4), RM515, RM223, L06, NKSbad2, FMbadh2-E7, BADEX7-5, Aro7, and SCU015RM (on chromosome 8) were highly associated with the 2AP (2-acetyl-1-pyrroline) content across the population. The alleles traced via these markers were also in high linkage disequilibrium (R(2) >0.70) and explained for approximately 12.1, 27.05, 27.05, 27.05, 25.42, 25.42, 20.53, 20.43, and 20.18% of the total phenotypic variation observed for these biomarkers, respectively. F2 plants harboring the favorable alleles of these effective markers produced higher levels of fragrance. Hence, these rice plants can be used as donor parents to increase the development of fragrance-biofortified tropical rice varieties adapted to growing conditions and consumer preferences, thus contributing to the global rice market.

    ABSTRACT: Herbivores can have a major influence on plant fitness. The direct impact of herbivory on plant reproductive output has long been studied, and recently also indirect effects of herbivory on plant traits and pollinator attraction received increasing attention. However, the link between these direct and indirect effects has seldom been studied. In this study we investigated effects of root herbivory on plant and floral traits, pollination success and reproductive outcome in the monocarpic perennial Cynoglossum officinale. We exposed 119 C. officinale plants to a range of root herbivore damage by its specialist herbivore Mogulones cruciger. We assessed the effect of herbivory on several plant traits, pollinator foraging behaviour and reproductive output and to unravel the link between these last two we also quantified pollen deposition and pollen tube growth and we applied a pollination experiment to test whether seed set was pollen limited. Larval root herbivory induced significant changes in plant traits and had a negative impact on pollinator visitation. Infested plants were reduced in size, had fewer flowers and received fewer pollinator visits at plant and flower level than non-infested plants. Also seed set was negatively affected by root herbivory, but this could not be attributed to pollen limitation since neither stigmatic pollen loads and pollen tube growth nor the results of the hand pollination experiment differed between infested and non-infested plants. Our observations demonstrate that although herbivory may induce significant changes in flowering behaviour and resulting plant-pollinator interactions, it does not necessarily translate into higher rates of pollen limitation. The observed reductions in reproductive output following infection can mainly be attributed to higher resource limitation compared to non-infested plants. This article is protected by copyright.

    ABSTRACT: Heavy metals greatly alter plant morphology and architecture, however detailed mechanisms of such changes are not fully explored. Two experiments were conducted to investigate the influence of cadmium (CdCl2 .2.5H2 O) on some germination, morphological, biochemical and histological characteristics of developing embryonic tissue of maize. In the first experiment, maize seeds were germinated in increased levels of CdCl2 (200 to 2000 μM) in sand and measurements were taken for changes in germination and seedling development attributes. Based on these parameters, 1000 μmol/L CdCl2 level was chosen for detailed biochemical and histological measurements. In the second experiment, the seeds were germinated in petri-dishes and supplied with 0 (control) and 1000 μmol/L CdCl2 level (Cd-treated). Radicle, plumule, coleoptile and coleorhiza were measured for biochemical and histological changes. Highest amount of Cd was noted in coleorhiza and radicle. Free proline, soluble sugars, anthocyamins, soluble phenolics, ascorbic acid, H2 O2 and MDA were found significantly higher in coleorhizae followed by coleoptile, radicle and plumule. Although radicle coleorhiza were relatively worse target of Cd than the other tissues, Cd stress reduced the cortical cell size, vascular tissues, deformed xylem and phloem parenchyma in all the parts. In conclusion, main reason for the reduced germination was influence of Cd on the architecture of coleorhiza and coleoptile, which was a result of oxidative stress and other physiological changes taking place in these tissues.

    ABSTRACT: The hormonal mechanisms of palm seeds germination are not well known. To better understand which aspects regulate germination in Arecaceae, we used macaw palm (Acrocomia aculeata (Jacq.) Lodd. Ex Mart.) seeds as a model. Endogenous hormonal concentration, tocopherols and tocotrienols and lipid peroxidation during germination were studied in the embryo and endosperm separately. Evaluations were performed in dry (D), imbibed (I), germinated (G) and non-germinated seeds (NG), in seeds treated (+GA3 ) and non-treated (control). Under GA3 treatment, seeds germinated faster and at higher percentage than control seeds. +GA3 treatment increased total bioactive gibberellins (GAs) in embryo during germination relative to control. Abscisic acid (ABA) concentrations decreased gradually from D to G in both tissues. Embryos of G seeds showed less ABA content than NG seeds in both treatments. The GAs/ABA ratio in the embryo was significantly higher in G seeds than NG ones. The +GA3 treatment did not significantly affect GAs/ABA ratios in either treatment. Cytokinin contents increased from dry to germinated seeds. Jasmonic acid (JA) levels increased and 1-aminocyclopropane-1-carboylic acid (ACC) concentrations decreased after imbibition. In addition, α-tocopherol and α-tocotrienol levels decreased, while the extent of lipid peroxidation increased in the embryo during germination. We conclude that germination in macaw palm seeds is guided by reductions in ABA content and, consequently, increased GAs/ABA ratio in the embryo. Furthermore, the imbibition process generates an oxidative stressful condition (as observed by changes in vitamin E and MDA). This article is protected by copyright. All rights reserved.

    ABSTRACT: Sesamin and sesamolin are the major oil soluble lignans present in the sesame seed possessing wide range of biological functions beneficial to human health. Understanding sesame domestication history with sesamin synthase gene expression could enable delineation of sesame putative progenitor. This report delved into the functional expression of sesamin synthase (CYP81Q1) gene during capsule maturation (0-40 days after flowering) in three wild Sesamum species and four sesame cultivars. Among the cultivated accessions only S. indicum (CO-1) exhibited transcript abundance of sesamin synthase gene along with high sesamin content similar to S. malabaricum while the other cultivated sesame showed low expression level. The sesamin synthase expression analysis coupled with quantification of sesamin level indicates that sesamin synthase gene was not positively favoured during domestication. The sesamin synthase expression pattern and lignan content along with phylogenetic analysis suggested a close relationship of cultivated sesame and wild species S. malabaricum. The high genetic identity between the two species S. indicum and S. malabaricum point towards the role of putative progenitor S. malabaricum in sesame breeding programs to broaden the genetic base of sesame cultivars. This study emphasizes the need to investigate the intraspecific variation and interspecific variation in primary gene pool, secondary and tertiary gene pool to develop superior sesame genotypes.

    ABSTRACT: Anthropogenic activities have resulted in cyanide (CN) contamination of both soil and water in many areas of the globe. While plants possess a detoxification pathway which serves to degrade endogenously generated CN, this system is readily overwhelmed, limiting the use of plants in bioremediation. Genetic engineering of additional CN degradation pathways in plants is one potential strategy to increase their tolerance to CN. Here we show that heterologous expression of microbial nitrilase enzymes targeted to the mitochondria increases CN tolerance in Arabidopsis. Root length in seedlings expressing either a CN dihydratase from Bacillus pumilis or a CN hydratase from Neurospora crassa was increased by 45% relative to wild-type plants in the presence of 50 μM KCN. We also demonstrate that in contrast to its strong inhibitory effects on seedling establishment, seed germination of the Col-0 ecotype of Arabidopsis is unaffected by CN.

    ABSTRACT: Nectar robbing occurs when floral visitors remove floral nectar through floral damage and usually without providing pollination in return. Even though nectar robbing may have negative, neutral or even positive effects on plant fitness, few studies have investigated temporal and spatial variation in robbing rate and their consequences, particularly in the tropics. In this study, robbing levels were estimated during three years in four populations of Salvia gesneriflora, a hummingbird-pollinated shrub endemic from central Mexico that is mainly robbed by birds, carpenter bees and bumble bees. The effect of robbing on nectar availability, flower longevity and on visitation rate by floral visitors was also evaluated. Our results indicate great variation in robbing levels across years and populations and a positive relationship between robbing level and flower abundance per population. Moreover, our results show that nectar availability is about eight times higher in unrobbed flowers than in robbed flowers and that nectar robbers prefer younger flowers, although lifespan of robbed and unrobbed flowers did not differ statistically. Primary and secondary nectar robbers showed a higher visitation rate compared to legitimate visitors and neither legitimate nor illegitimate floral visitors seem to discriminate between robbed and unrobbed flowers. These results suggest that robbers may respond to food availability and that all floral visitors apparently could not differentiate between robbed and unrobbed flowers. Finally, results show that nectar robbers prefer the youngest flowers, which suggests that strong competition for access to nectar between pollinators and robbers may occur, mainly at the first stages of the flowers.
