“…The best‐studied stress in bean breeding is drought stress (Beebe, Rao, Blair, & Acosta‐Gallegos, 2013; Blair, Cortés, & This, 2016; Miklas et al., 2006; Rodriguez et al., 2015; Villordo‐Pineda, González‐Chavira, Giraldo‐Carbajo, Acosta‐Gallegos, & Caballero‐Pérez, 2015). The most widely used strategy consists of the identification of wild and landrace germplasm resistant to drought stress (Cortés, Monserrate, Ramírez‐Villegas, Madriñán, & Blair, 2013; Porch et al., 2013).…”

Despite its economic, social, biological, and cultural importance, wild forms of the genus Phaseolus are not well represented in germplasm banks, and they are at great risk due to changes in land use as well as climate change. To improve our understanding of the potential geographical distribution of wild beans (Phaseolus spp.) from Mexico and support in situ and ex situ conservation programs, we determined the climatic adaptation ranges of 29 species and two subspecies of Phaseolus collected throughout Mexico. Based on five biotic and 117 abiotic variables obtained from different databases—WorldClim, Global‐Aridity, and Global‐PET—we performed principal component and cluster analyses. Germplasm was distributed among 12 climatic types from a possible 28. The general climatic ranges were as follows: 8–3,083 m above sea level; 12.07–26.96°C annual mean temperature; 10.33–202.68 mm annual precipitation; 9.33–16.56 W/m2 of net radiation; 11.68–14.23 hr photoperiod; 0.06–1.57 aridity index; and 10–1,728 mm/month of annual potential evapotranspiration. Most descriptive variables (25) clustered species into two groups: One included germplasm from semihot climates, and the other included germplasm from temperate climates. Species clustering showed 45% to 54% coincidence with species previously grouped using molecular data. The species P. filiformis, P. purpusii, and P. maculatus were found at low‐humidity locations; these species could be used to improve our understanding of the extreme aridity adaptation mechanisms used by wild beans to avoid or tolerate climate change as well as to introgress favorable alleles into new cultivars adapted to hot, dry environments.

“…This result suggests a possible role for PvTIP1;1 in response to drought stress in common bean. One of the mechanisms for avoiding drought stress in common bean is an increased root depth (Beebe et al 2013). The expression pattern of AtTIP1;1 promoter is correlated with elongating cells in Arabidopsis roots (Ludevid et al 1992).…”

Plant Aaquaporins are a large and diverse family of water channel proteins that are essential for several physiological processes in living organisms. in all living organisms. In plants, this family has the highest diversity of protein isoforms and substrate specificities compared to animals and bacteria. Numerous studies have linked plant aquaporins with a plethora of processes, such as nutrient acquisition, CO 2 transport, plant growth and development, and response to abiotic stresses.However, little is knowns about this protein family in common bean. Here, we present a genomewide identification of the aquaporin gene family in common bean (Phaseolus vulgaris L.), a legume crop essential for human nutrition. We identified 41 full-length coding aquaporin sequences in the common bean genome, divided by phylogenetic analysis into five sub-families (PIPs, TIPs, NIPs, SIPs and XIPs). Residues determining substrate specificity of aquaporins (i.e., NPA motifs and ar/R selectivity filter) seem conserved between common bean and other plant species, allowing inference of substrate specificity for these proteins. Thanks to the availability of RNA-sequencing datasets, expression levels in different organs and in leaves of wild and domesticated bean accessions were evaluated. Three aquaporins (PvTIP1;1, PvPIP2;4 and PvPIP1;2) have the overall highest mean expressions, with PvTIP1;1 having the highest expression among all aquaporins. We performed an EST database mining to identify drought responsive aquaporins in common bean. This analysis showed a significant increase in expression for PvTIP1;1 in drought stress conditions compared to well-watered environments. The pivotal role suggested for PvTIP1;1 in regulating water homeostasis and drought stress response in the common bean, should be verified by further field experimentation under drought stress.

“…The result of current study is in agreement with the reports of Beebe et al [7] who reported that common beans adapt stress conditions due to climate change variables through production and accumulation of carbohydrates, such as waxes, extra layers of epidermal cells, increased fiber content and pH change in their cell cytoplasm. Beebe et al [8] also defined drought tolerance as the capability of plants to resist the stress by adjusting cell osmosis, cell plasticity, and cell size. Sallam [35] reported that the host resistance might be increased by change in pH of plant cell cytoplasm, due to the increase in phenolic acid content, resulting in inhibition of pathogen development.…”

“…In general, drought resistance mechanisms can include drought escape; drought avoidance; and drought tolerance [7,32]. Drought escape allows plants to accelerate their cell cycle with an early flowering and maturity, and rapidly relocates metabolites to seed production [8,30] and away from leaves and shoot tissues [33,34]. Drought avoidance is the capability to keep high tissue water potential through increased rooting depth, hydraulic conductance reduction, and radiation absorption reduction in leaves, water-loss area reduction, reduced absorption of radiation by leaf movement, and reduced surface evaporation [7,30,35].…”

“…Among the abiotic constraints are inadequate total rainfall, erratic rainfall distribution, periodic water stress, extended dry spells during the crop critical growth as a result of climate change [2,7,8]. Low soil fertility, shortage or excess of mineral salts and extreme lower pH of soil are also the abiotic factors that limit common bean production [9][10][11].…”

Common bacterial blight (CBB), caused by Xanthomonas axonopodis pv. phaseoli Smith (Xap) and Xanthomonas axonopodis pv. phaseoli var. fuscan Burkholder (Xapf) is the most serious biotic constraint of common bean (Phaseolus vulgaris L.) production. Variables temperature and moisture are dominant climate factors that affect common bean growth as well as the development of CBB epidemics. Two sets of experiments were conducted in the Plant Pathology Laboratory of Haramaya University) to assess the effect of temperature and moisture on the resistance level of common bean in 2014 and 2015. In the first experiment, two common bean varieties (Gofta and Mexican 142) were inoculated with two bacterial strains (Xap and Xapf) and a control were incubated at four temperature levels (28°C, 30°C, 32°C and 34°C) in growth chambers. In the second experiment, three-soil moisture levels (100%, 75% and 50%) were employed to that of experiment one. The treatment combinations were arranged in factorial completely randomized design (CRD) in the growth chambers for both series of experiments. The disease rating was significantly (P<0.05) affected by common bean varieties and temperature levels at 17 days after inoculation (DAI). Higher disease rating was recorded on the variety Mexican 142 than on Gofta. The highest (1.75) mean disease rating was recorded at 28°C and the lowest (1.44) at 34°C. The mean disease ratings differed significantly among the moisture levels. The highest (2.01) mean disease rating was recorded from 75% moisture content, while the lowest (1.80) disease rating was obtained from 50% moisture content. The results of these series of experiments indicated that climate change effects above optimum level would not be favorable for CBB development in the arid and semi-arid agro ecologies unless new bacterial strains adapted to the drought tolerant common beans in the area.
