Fenugreek as a self-pollinated plant is ideal for genome-wide association mapping where traits can be marked by their association with natural mutations. However, fenugreek is poorly investigated at the genomic level due to the lack of information regarding its genome. To fill this gap, we genotyped a collection of 112 genotypes with 153,881 SNPs u...

Gene mapping aims to identify the causal genetic factors underlying any trait of interest. To map those genetic factors, three main pre‐requisites are required, i.e. traits measured on quantitative scales, segregating populations, and linkage maps. Quantitative traits are controlled by many genes and can be collected by screening segregating popula...

Genotype-environment interaction (GxE) has a great impact on wheat physiology, morphology and grain yield (GY). We evaluated an association mapping panel of spring wheat advanced lines for chlorophyll content, canopy temperature (CT), and yield-related traits under three different watering regimes in two consecutive growing seasons. Genome-wide ass...

The availability of high-throughput sequencing technologies increased our understanding of different genomes. However, the genomes of all living organisms still have many unidentified coding sequences. The increased number of missing small open reading frames (sORFs) is due to the length threshold used in most gene identification tools, which is tr...

The focus on increasing wheat (Triticum aestivum L.) grain yield at the expense of grain quality and nutrient accumulation can lead to shortages in macronutrient minerals, which are dangerous for human health. This is important, especially in nations where bread wheat is used in most daily dietary regimens. One efficient way to guarantee nutritiona...

Developing high-yielding and resilient maize hybrids is essential to ensure its sustainable production with the ongoing challenges of considerable shifts in global climate. This study aimed to explore genetic diversity among exotic and local maize inbred lines, evaluate their combining ability, understand the genetic mechanisms influencing ear char...

Salinity is a significant factor restricting plant growth and production. The effect of salinity stress on different growth parameters of 111 fenugreek genotypes was examined in an experiment with three salinity levels (0, 3000, 6000 mgL−1). A completely randomized block design with two replicated pots per treatment was used. Non-significant treatm...

While the response of Arabidopsis thaliana to drought, herbivory or fungal infection has been well‐examined, the consequences of exposure to a series of such (a)biotic stresses are not well studied. This work reports on the genetic mechanisms underlying the Arabidopsis response to single osmotic stress, and to combinatorial stress, either fungal in...

Water deficit poses significant environmental stress that adversely affects the growth and productivity of durum wheat. Moreover, projections of climate change suggest an increase in the frequency and severity of droughts, particularly in arid regions. Consequently, there is an urgent need to develop drought-tolerant and high-yielding genotypes to...

Distinctness, uniformity, and stability (DUS) test is the legal requirement in crop breeding to grant the intellectual property right for new varieties by evaluating their morphological characteristics across environments. On the other hand, molecular markers accurately identify genetic variations and validate the purity of the cultivars. Therefore...

Increasing wheat grain yield while ignoring grain quality and metal accumulation can result in metal deficiencies, particularly in countries where bread wheat accounts for the majority of daily dietary regimes. When the accumulation level exceeds a certain threshold, it becomes toxic and causes various diseases. Biofortification is an effective met...

Background Cabbage white butterflies (Pieris spp.) can be severe pests of Brassica crops such as Chinese cabbage, Pak choi (Brassica rapa) or cabbages (B. oleracea). Eggs of Pieris spp. can induce a hypersensitive response-like (HR-like) cell death which reduces egg survival in the wild black mustard (B. nigra). Unravelling the genetic basis of thi...

Understanding how strawberry (Fragaria x ananassa) nutritional and quality traits are genetically regulated and correlated is an essential step towards improving marker-assisted breeding programmes in this crop. A first step to achieve this goal was to construct a single nucleotide polymorphism (SNP)-based genetic map of 140 F1 individuals of a cro...

Understanding codon usage patterns and their shaping factors in members of the Solanaceae family may reflect important features of their evolutionary history. Here, we investigated codon usage bias (CUB) over the whole genome of tobacco, tomato and potato. Analyzing the effective number of codons (ENc) revealed a weak CUB over the whole genome of t...

Water deficiency is one of the major environmental constraints, limiting agricultural productivity, and plays the major role in the distribution of plant species across different types of environments. Forty-seven peanut mutant lines were developed by γ-radiation mutagenesis of two commercial genotypes (Giza-6 and NC). The yield performance and wat...

Background and aims: The stomatal conductance (gs) of most plant species decreases in response to elevated atmospheric CO2 concentration. This response could have a significant impact on plant water use in a future climate. However, the regulation of the CO2-induced stomatal closure response is not fully understood. Moreover, the potential genetic...

We used three approaches to map the yellow rust resistance gene Yr7 and identify associated SNPs in wheat. First, we used a traditional QTL mapping approach using a double haploid (DH) population and mapped Yr7 to a low-recombination region of chromosome 2B. To fine map the QTL, we then used an association mapping panel. Both populations were SNP a...

Background: Phosphorus is often present naturally in the soil as inorganic phosphate, Pi, which bio-availability is limited in many ecosystems due to low soil solubility and mobility. Plants respond to low Pi with a Pi Starvation Response, involving Pi sensing and long-distance signalling. There is extensive cross-talk between Pi homeostasis mecha...

YIELD and its related traits; heading date, hundred kernel weight and kernels number as well as harvest index and biological yield are complex traits that require the concerted action of many genes and are affected by environmental cues. To genetically dissect those traits, 140 recombinant inbred lines (RILs) genotyped with 120 DArT and SSR markers...

Stomata are small pores in the surface of plant leaves, balancing the uptake of CO2 against the loss of water vapour. As drought stress is projected to increase in many parts of the world, an improved understanding of how plants regulate their stomata in response to environmental stimuli may have important implications for securing food production...

Drought stress was imposed on two sets of Arabidopsis thaliana genotypes grown in sand under short day conditions and analysed for several shoot and root growth traits. The response to drought was assessed for quantitative trait locus (QTL) mapping in a genetically diverse set of Arabidopsis accessions using genome-wide association (GWA) mapping, a...

Plant growth and development are influenced by the genetic composition of the plant (G), the environment (E), and the interaction between them (G × E). To produce suitable genotypes for multiple environments, G × E should be accounted for and assessed in plant-breeding programs. Here, we review the genetic basis of G × E and its consequence for qua...

Plant growth and productivity are greatly affected by drought, which is likely to become more threatening with the predicted global temperature increase. Understanding the genetic architecture of complex quantitative traits and their interaction with water availability may lead to improved crop adaptation to a wide range of environments. Here, the...

The genetic basis of the wide variation for nutritional traits in Brassica rapa is largely unknown. A new Recombinant Inbred Line (RIL) population was profiled using High Performance Liquid Chromatography (HPLC) and Nuclear Magnetic Resonance (NMR) analysis to detect quantitative trait loci (QTLs) controlling seed tocopherol and seedling metabolite...

A recombinant inbred line (RIL) population was produced based on a wide cross between the rapid-cycling and self-compatible genotypes L58, a Caixin vegetable type, and R-o-18, a yellow sarson oil type. A linkage map based on 160 F7 lines was constructed using 100 Single nucleotide polymorphisms (SNPs), 130 AFLP®, 27 InDel, and 13 publicly available...

The goal of the present study was to select BC2-lines from a cross between Hordeum vulgare and H. vulgare ssp. spontaneum and to identify introgressed candidate regions responsible for a superior pre-flowering development across environments including drought stress conditions by using stability parameter and genotype mean estimates. Three experime...
