“…Under natural conditions, both drought and Pi deficiency interfere with plant metabolism via various stress signals and hormonal changes that play essential roles in regulation processes (Ha et al, 2012 ; Osakabe et al, 2013 ; López-Arredondo et al, 2014 ; Cerezini et al, 2016 ; Srivastava et al, 2016 ; Nasr Esfahani et al, 2017 ). Drought and Pi deficiency result in decreases in photosynthetic activity, soluble protein contents, nutrient uptake, and metabolic enzyme activities, causing significant losses in plant growth and biomass, and ultimately in yield components (Garg et al, 2004 ; Shubhra et al, 2004 ; Dita et al, 2006 ; Gobarah et al, 2006 ; Gunes et al, 2006 ; Jin et al, 2006 ; Santos et al, 2006 ; Kunert et al, 2016 ; Goufo et al, 2017 ). Poor nodule development and dis-functioning are frequently detected in legume crops as a result of drought and Pi deficiency, leading to a rapid decrease of nitrogenase activity, and thus BNF efficiency (Sinclair et al, 2007 ; Charlson et al, 2009 ; Gil-Quintana et al, 2013 ; Sulieman et al, 2013 ; Cabeza et al, 2014 ; Nasr Esfahani et al, 2014 ).…”

Water deficit and phosphate (Pi) deficiency adversely affect growth and biological nitrogen fixation (BNF) of legume crops. In this study, we examined the impact of interaction between soil water conditions and available soil-Pi levels on growth, nodule development and BNF potential of nine cowpea varieties grown on dry savanna soils. In our experimental design, soils with different available soil-Pi levels, i.e., low, moderate, and high soil-Pi levels, collected from various farming fields were used to grow nine cowpea varieties under well-watered and water-deficit conditions. Significant and severe water deficit-damaging effects on BNF, nodulation, growth, levels of plant-nitrogen (N) and -phosphorus (P), as well as shoot relative water content and chlorophyll content of cowpea plants were observed. Under well-watered and high available soil-Pi conditions, cowpea varieties IT07K-304-9 and Dan'Ila exhibited significantly higher BNF potential and dry biomass, as well as plant-N and -P contents compared with other tested ones. Significant genotypic variations among the cowpeas were recorded under low available soil-Pi and water-deficit conditions in terms of the BNF potential. Principal component (PC) analysis revealed that varieties IT04K-339-1, IT07K-188-49, IT07K-304-9, and IT04K-405-5 were associated with PC1, which was better explained by performance for nodulation, plant biomass, plant-N, plant-P, and BNF potential under the combined stress of water deficit and Pi deficiency, thereby offering prospects for development of varieties with high growth and BNF traits that are adaptive to such stress conditions in the region. On another hand, variety Dan'Ila was significantly related to PC2 that was highly explained by the plant shoot/root ratio and chlorophyll content, suggesting the existence of physiological and morphological adjustments to cope with water deficit and Pi deficiency for this particular variety. Additionally, increases in soil-Pi availability led to significant reductions of water-deficit damage on dry biomass, plant-N and -P contents, and BNF potential of cowpea varieties. This finding suggests that integrated nutrient management strategies that allow farmers to access to Pi-based fertilizers may help reduce the damage of adverse water deficit and Pi deficiency caused to cowpea crop in the regions, where soils are predominantly Pi-deficient and drought-prone.

“…Then the plants were rehydrated until the end of their cycle. During stress, A was measured at three hours: 09:00 h, noon, and 15:00h [4]. In this second experiment, Carioca with an extra Pi supply exhibited higher A values only on the first day of water deficit at 09:00 h and on the third day at 15:00 h. Therefore, the extra foliar Pi effect did not cause significant differences in A for Carioca.…”

“…However, due to growth arrest, sugars-P accumulation in the photosynthetic cells can stop Triose-Phosphate (Triose-P) export from the chloroplast due to the low availability of Pi in the cytoplasm. The export of Triose-P is done by Phosphate Translocator (PT) antiporter in exchange of Pi, and it is controlled by Fructose-2,6-Phosphate (F-2,6-P) concentration in the cytoplasm, which is increased by growth arrest under drought [4].…”

“…There were no significant differences in yield with or without Pi supply [3]. Two of the genotypes studied, Carioca (widely used by farmers) and Ouro Negro (a new black seeded cultivar), were used in a second experiment in the greenhouse [4]. The treatments of Pi foliar supply two days before water withholding, used in the first experiment, were repeated here.…”

The morpho-agronomic characterization of gene banks is a key step in enabling breeding programs to efficiently exploit genetic resources. Several studies have evaluated the root system traits of the common bean to develop genotypes better adapted to drought. We examined the root systems of 1000 common bean accessions, from the Agronomic Institute of Campinas gene bank to: count the number of whorls and basal roots, estimate the divergence between accessions and evaluate the 47 most divergent genotypes under drought. The average numbers of whorl and basal roots for the 1,000 accessions were 2.07 and 8.09, respectively. Seven different clusters were identified using the Mahalanobis genetic divergence analysis and the Tocher optimization method, from which the 47 most divergent genotypes were selected. Both genotype and water treatments, in the pre-blooming period, significantly affected root length, root surface area, root volume, number of pods, seeds per plant and grain yield. However, only water treatment significantly affected stomatal conductance, with water treatment x genotype interaction only having a significant effect on this characteristic. Water deficit reduced the average grain yield by 52%; the most promising genotypes under water deficit considering both root growth and grain yield were: RAI 76,
