Abstract Drought stress during the reproductive stage and declining soybean yield potential raise concerns about loss economic return. In this study, ten cultivars were characterized for 20 traits to identify (R1–R6) drought-tolerant soybean. resulted in a marked reduction (17%) pollen germination. The reduced stomatal conductance coupled with high canopy temperature seed number (45%) weight (35%). followed by rehydration increased hundred at compensation of number. Further, oil decreased, protein increased, responded differently under drought compared control. general, tolerance scores displayed lower quality content vice versa. Among cultivars, LS5009XS G4620RX showed maximum weight. observed variability leaf reflectance properties their relationship physiological or components suggested that leaf-level sensing information can be used differentiating drought-sensitive from tolerant ones. study led identification drought-resilient cultivars/promising which exploited breeding develop multi-stress cultivars.

Landraces and indigenous varieties comprise valuable sources of crop species diversity. Their utilization in plant breeding may lead to increased yield enhanced quality traits, as well resilience various abiotic biotic stresses. Recently, new approaches based on the rapid advancement genomic technologies such deciphering pangenomes, multi-omics tools, marker-assisted selection (MAS), genome-wide association studies (GWAS), CRISPR/Cas9 gene editing greatly facilitated exploitation landraces modern breeding. In this paper, we present a comprehensive overview implementation highlight their importance pinpointing genetic basis desirable traits annual, perennial herbaceous, woody cultivated Mediterranean region. The need for further employment advanced -omic unravel full potential underutilized diversity is also indicated. Ultimately, large amount data emerging from investigation reveals source genes role mitigating ongoing risks posed by climate change agriculture food security highlighted.

Currently, the world population is increasing, and humanity facing food nutritional scarcity. Climate change variability are a major threat to global security, reducing crop productivity in tropical subtropical regions of globe. Cowpea has potential make significant contribution security. In addition, it can be part sustainable system, being genetic resource for future improvement, contributing resilience improving agricultural sustainability under climate conditions. malnutrition prone sub-Saharan Africa (SSA) countries, cowpea become strategic dryland legume addressing insecurity malnutrition. Therefore, this review aims assess SSA countries as climate-resilient existing production challenges perspectives. leaves immature pods rich diverse nutrients, with high levels protein, vitamins, macro micronutrients, minerals, fiber, carbohydrates compared its grain. truly multifunctional maintaining good health non-communicable human diseases. However, leafy vegetable, not been researched promoted sufficiently because security due low yield potential, susceptibility biotic abiotic stresses, quality assurance issues, policy regulation, cultural beliefs (it considered livestock feed). The development superior vegetable approached different ways, such conventional breeding gene stacking, speed breeding, mutation space demand-led pan-omics approach, local government policies. successful genotypes that high-yielding value well having resistance biotics tolerant stress could also used address malnutrition-related Africa.

Promoting sustainable agriculture by exploiting plant growth-promoting rhizobacteria (PGPR) to improve maize and cowpea crops

PeerJ, Год журнала: 2024, Номер 12, С. e16836 - e16836

Maize and cowpea are among the staple foods most consumed by of African population, significant importance in food security, crop diversification, biodiversity preservation, livelihoods. In order to satisfy growing demand for agricultural products, fertilizers pesticides have been extensively used increase yields protect plants against pathogens. However, excessive use these chemicals has harmful consequences on environment also public health. These include soil acidification, loss biodiversity, groundwater pollution, reduced fertility, contamination crops heavy metals, etc . Therefore, essential find alternatives promote sustainable agriculture ensure well-being people. Among alternatives, techniques that offer sustainable, environmentally friendly solutions reduce or eliminate inputs increasingly attracting attention researchers. One such alternative is beneficial microorganisms as plant growth-promoting rhizobacteria (PGPR). PGPR provides a variety ecological services can play an role yield enhancers biological control agents. They root development plants, increasing their capacity absorb water nutrients from soil, stress tolerance, disease development. Previous research highlighted benefits using PGPRs productivity. A thorough understanding mechanisms action exploitation biofertilizers would present promising prospect production, particularly maize cowpea, ensuring prosperous agriculture, while contributing security reducing impact chemical environment. Looking ahead, should continue deepen our crops, with view constantly improving practices. On other hand, farmers industry players need be made aware encouraged adopt them

Опубликована: Июль 15, 2024

As valuable sources of plant-based protein, leguminous vegetables (grain legumes) are essential for global food security and contribute to body growth development in humans as well animals. Climate change is a major challenge agriculture that creates problems the plants. However, legume productivity threatened by climate factors, including rising temperatures, shifting precipitation patterns, increased atmospheric carbon dioxide levels, intensified extreme events, altered pest/pathogen activity. This review synthesizes approximately 136 studies assess effects on crops. Under all emissions trajectories, mean temperatures projected rise beyond optimal growing thresholds 2050, carrying yield reductions between 10 49% beans, soybeans, cowpeas, lentils without adaptation measures. The elevated may transiently enhance yields up 18%, but benefits dramatically decline above 550 ppm cannot offset other impacts. Altered rainfall along with recurrent drought heat waves also expected decrease crop yields, seed quality, soil nitrogen levels worldwide. Furthermore, proliferation pests fungal diseases poses significant risks, amplified shifts 84% reviewed studies. These multifaceted impacts threaten gains sustainably meeting protein demand. Realizing resilience will require accelerated heat/drought-tolerant varieties, enhanced climate-informed agronomic practices, strong policy interventions, social safety nets explicitly supporting producers, addition policies/steps governments taking address challenges crisis. highlights adaptations mechanisms required crops thrive fulfill their roles nutrition. It explores how these can be improved better withstand environmental stresses, nutritional profiles, increase yields. Additionally, discusses importance legumes sustainable security, emphasizing potential future feeding population. By focusing critical aspects, aims underscore ensuring healthy supply.

The majority of cowpea (Vigna unguiculata (L.) Walp.) produced in the U.S. is planted shortly after summer rains and subsequently depends on rain or artificial irrigation. Therefore, excessive precipitation poor soil drainage will cause plants to suffer temporary waterlogging, reducing submerged tissue's oxygen level. Although sensitive moisture can induce several morpho-physiological changes with adverse impacts yield its early stages development. current study subjected 30 genotypes 10-days waterlogging at seedling stage under a controlled environment. dynamic 24 parameters optimal water conditions were analyzed understand cowpea's response waterlogging. Significant treatment, genotypes, their interactions (P < 0.001) observed for most measured parameters. results indicated that plant height (PH), leaf area (LA), fresh (FW) dry weight (DW) significantly decreased compared control treatments. Similar obtained net photosynthesis (Pn), stomatal conductance (gs), intercellular CO2 concentration (Ci), transpiration rate (E). However, use efficiency (WUE) adventitious roots (ARs) increased linearly conditions. Waterlogging also declined chlorophyll fluorescence except non-photochemical quenching (qN), which excess moisture. In addition, tolerance coefficient (WTC) multivariate analysis (MCA) methods used characterize tolerance. Accordingly, genotype Dagupan Pangasinan, UCR 369, Negro classified as tolerant, while EpicSelect.4 ICARDA 140071, sensitive. traits determined from this may be useful genetic engineering breeding programs integrate
