“…However, agronomic adaptation is highly site specific: In Europe, for instance, cool season legumes such as dry peas are grown in warm regions of South Europe such as Spain, while soybean is produced in cooler Central European regions under rainfed conditions (FAOSTAT, 2015;Schreuder and De Visser, 2014). Moreover, both warm and cool season legumes are similarly affected by drought in terms of yield reduction (Toker and Mutlu, 2011). Other features of adaptation are comparable as well between the major warm and cool season grain legume species (Miller et al, 2002), and specific adaptation differences might be further mitigated by climate change progress in particular growing regions (Cutworth et al, 2007).…”

“…Phaseolus beans, soybean, peanut, and few others are classified as warm or tropical season legumes, while most others are considered cool season food legumes (Toker and Mutlu, 2011) playing particularly important roles in Mediterranean agriculture (Howieson et al, 2000). Cool season legumes have a lower minimum germination temperature, are less susceptible to frost, and are generally grown under rainfed conditions as compared to warm season legumes.…”

SummaryThe United Nations have declared 2016 as the International Year of Pulses, which aims at communicating the various benefits of legume cropping and legume-protein-based food consumption. As the term “pulses” is inherently excluding soybean from other grain legumes, this review aims at challenging the scientific justification of this separation from both historical and crop science perspectives toward a better understanding of grain legumes and their contributions to food security. An analysis of the historical development and uses of the term “pulses” reveals that it is not used unambiguously throughout the recent scientific literature, and that the separation of soybean from other grain legumes occurred rather recently. Soybean, while being extensively used as an oilseed and animal feedstuff in some parts of the world, is an important protein crop species in other regions with a seed protein content of 40% and outstanding nutritional and food health properties as compared to most other grain legumes. Owing to similar agronomic features such as symbiotic nitrogen fixation and comparable seed protein properties, it does not seem scientifically justified to separate soybean from other food legumes. Therefore, focusing on “grain legumes” rather than “pulses” would better support food security and nutritional quality goals.

“…Important seed germination and plant growth parameters were assessed and compared with a shift in expression of antioxidant genes related to the accumulation of ROS-toxic molecules in plant host tissue; the two major indicators of the plant physiological health and resilience against abiotic stress (Das & Roychoudhury, 2014;Sharma et al, 2012). Drought is widespread problem and major constraint in production of leguminous crops (Toker & Mutlu, 2011). The crops may be affected by drought at any stage of the life cycle; however, certain stages including germination and seedling growth are critical for plant establishment, acclimation and performance (Pessarakli, 1999).…”

Chickpea is an important leguminous crop grown worldwide due to its nutritional and economic value. However, abiotic stress, primarily caused by drought, has limited chickpea production. This study highlights endosymbiotic plant growth promotion as well as alleviation of abiotic stress in germinating chickpea seeds and seedlings under drought stress conditions. Seed produced by F1 endosymbiotic plants under controlled environment was used to conduct this second‐generation (F2) study in the greenhouse. Fungal and bacterial endosymbionts improved seed germination and enhanced root and shoot growth in second‐generation seeds produced by applying drought stress without endophytes. Expression levels of antioxidant genes, proline, SOD‐superoxide dismutase and dehydrin, were downregulated, which characterizes enhanced oxidative stress tolerance and reduced reactive oxygen species (ROS) in host cells. The endosymbiont beneficial effect on plant resilience and improved phenotypes was translated into increased nutrient quality of second‐generation seed. This study indicates the potential of the fungal and bacterial endosymbionts to moderate drought stress in plants by triggering epigenetic changes inherited across chickpea generations which correlated with enhanced resilience and improved agricultural traits in this globally important crop.

“…Specific attention is paid to pigeonpea, and we emphasize that understanding the variation in physiological and morphological phenotypes in crop wild relatives can be used to inform germplasm collection efforts. Harsh environments can cause significant yield losses and negatively impact biomass, pod number, seed yield, seed weight, and quality in cultivated pigeonpea (Toker et al 2007;Khan et al 2010;Toker and Mutlu 2011;Hasanuzzaman et al 2013;Pagano 2014). One of the most pressing issues for global food security is water availability because the agriculture industry accounts for some 70% of total freshwater consumption (FAO 2012), and the irrigation water sources and rain patterns that feed agricultural land are vulnerable to the effects of climate change.…”

The Pigeonpea Genome

Whole-genome sequencing is at the cutting edge of life sciences in the new millennium. Since the first genome sequencing of the model plant Arabidopsis thaliana in 2000, whole genomes of about 70 plant species have been sequenced and genome sequences of several other plants are in the pipeline. Research publications on these genome initiatives are scattered on dedicated web sites and in journals with all too brief descriptions. The individual volumes elucidate the background history of the national and international genome initiatives; public and private partners involved; strategies and genomic resources and tools utilized; enumeration on the sequences and their assembly; repetitive sequences; gene annotation and genome duplication. In addition, synteny with other sequences, comparison of gene families and most importantly potential of the genome sequence information for gene pool characterization and genetic improvement of crop plants are described.
