“…The genotypes used were: Gurguéia and Novaera, two modern commercials genotypes recently launched by the Brazilian Agricultural Research Corporation (EMBRAPA), with high potential yield for use in high-input agriculture by big farmers; and EPACE-10, a traditional local genotype selected for use by small farmers without high technology, well adapted to drought and high temperature ( Pimentel et al, 1999b , Costa et al, 2002 ), and Paulistinha, another traditional local genotype selected in a marginal area under high temperature and water deficit ( Freire Filho et al, 2005 , Gonçalves et al, 2020 ) ( Table 1 ). The analyses were performed in four distinct phenological stages: vegetative, pre-flowering, flowering, and pod filling.…”

“…These physiological parameters were successfully used to discriminate cowpea adaptation to water deficit ( Pimentel et al, 1999b ) and high temperature ( Costa et al, 2002 ). Two high-yielding modern commercials genotypes indicated for high-input agriculture ( Vasconcelos et al, 2010 ) and two low-yielding traditional local genotypes cultivated in low-input agriculture ( Gonçalves et al, 2020 ) will be the object of study.…”

“…Similarly, an evaluation of 21 cowpea genotypes identified high SPC in COVU-702 (27.7%) and HC-98-64 (27.9%) [ 86 ]. In another study, GonÇalves et al [ 87 ] identified high SPC in Paulistinha (29.2%) among 18 tested cowpea genotypes. An evaluation of 30 Brazilian cowpea lines for protein, vitamin, and mineral content identified high SPC in MNC01-649F-2 (28.3%), BRS-Cauamé (27.8%), BRS-Paraguacu (27.7%), BRS-Marataoa (27.4%), Canapuzinho (25.0%), BRS-Tumucumaque (24.8%), and MNC01-631F-15 (24.6%) [ 88 ].…”

Grain legumes are a rich source of dietary protein for millions of people globally and thus a key driver for securing global food security. Legume plant-based ‘dietary protein’ biofortification is an economic strategy for alleviating the menace of rising malnutrition-related problems and hidden hunger. Malnutrition from protein deficiency is predominant in human populations with an insufficient daily intake of animal protein/dietary protein due to economic limitations, especially in developing countries. Therefore, enhancing grain legume protein content will help eradicate protein-related malnutrition problems in low-income and underprivileged countries. Here, we review the exploitable genetic variability for grain protein content in various major grain legumes for improving the protein content of high-yielding, low-protein genotypes. We highlight classical genetics-based inheritance of protein content in various legumes and discuss advances in molecular marker technology that have enabled us to underpin various quantitative trait loci controlling seed protein content (SPC) in biparental-based mapping populations and genome-wide association studies. We also review the progress of functional genomics in deciphering the underlying candidate gene(s) controlling SPC in various grain legumes and the role of proteomics and metabolomics in shedding light on the accumulation of various novel proteins and metabolites in high-protein legume genotypes. Lastly, we detail the scope of genomic selection, high-throughput phenotyping, emerging genome editing tools, and speed breeding protocols for enhancing SPC in grain legumes to achieve legume-based dietary protein security and thus reduce the global hunger risk.

Vigna unguiculata is an important source of proteins and energy for humans and animals. However, postharvest losses caused by Callosobruchus maculatus can reach from 20 to 100% of stored seeds. In this study, the insecticide potential of compounds extracted from Himatanthus drasticus latex was assessed. The latex was extracted with ethanol (70%) and then partitioned through sequential use of hexane and chloroform. These fractions were investigated by chromatography to determine their chemical composition. Plumieride, identified in a hydroalcoholic subfraction, was tested for insecticidal activity against C. maculatus. The ethanolic fraction (LC 50 = 0.109; LC 90 = 0.106%) and the plumieride (LC 50 = 0.166; LC 90 = 0.167%) were lethal to larvae. Plumieride (0.25%) delayed larval development, and mortality reached 100%. Its inhibitory action on intestinal α-amylase from larvae was higher (89.12%) than that of acarbose (63.82%). Plumieride (0.1%) inhibited the enzyme α-amylase in vivo in the larval intestine. This result was confirmed by a zymogram test performed by SDS-PAGE when the enzyme electrophoresed on gel copolymerized with starch. When spread on seeds, the hydroalcoholic fraction (1.0%) reduced infestation. The loss of seed mass was 5.26% compared to the control (44.97%). The results confirm the effect of latex compounds in protecting stored seeds against weevil infestation.
