Six foxtail millet ASR genes were regulated by various stress-related signals. Overexpression of ASR1 increased drought and oxidative tolerance by controlling ROS homeostasis and regulating oxidation-related genes in tobacco plants. Abscisic acid stress ripening (ASR) proteins with ABA/WDS domains constituted a class of plant-specific transcription factors, playing important roles in plant development, growth and abiotic stress responses. However, only a few ASRs genes have been characterized in crop plants and none was reported so far in foxtail millet (Setaria italic), an important drought-tolerant crop and model bioenergy grain crop. In the present study, we identified six foxtail millet ASR genes. Gene structure, protein alignments and phylogenetic relationships were analyzed. Transcript expression patterns of ASR genes revealed that ASRs might play important roles in stress-related signaling and abiotic stress responses in diverse tissues in foxtail millet. Subcellular localization assays showed that SiASR1 localized in the nucleus. Overexpression of SiASR1 in tobacco remarkably increased tolerance to drought and oxidative stresses, as determined through developmental and physiological analyses of germination rate, root growth, survival rate, relative water content, ion leakage, chlorophyll content and antioxidant enzyme activities. Furthermore, expression of SiASR1 modulated the transcript levels of oxidation-related genes, including NtSOD, NtAPX, NtCAT, NtRbohA and NtRbohB, under drought and oxidative stress conditions. These results provide a foundation for evolutionary and functional characterization of the ASR gene family in foxtail millet.

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.

“…Genetic variation patterns frequently coincide with environmental variation patterns (Cortés, Chavarro, Madriñán, This, & Blair, 2012). Current research is challenged with collecting, characterizing, and preserving the genetic diversity of wild Phaseolus species as well as searching for better strategies for using genetic resources in breeding (Andueza‐Noh, Camacho‐Pérez, Martínez‐Castillo, & May‐Pat, 2016; Bellon et al., 2009; Porch et al., 2013; Ramírez‐Villegas, Khoury, Jarvis, Debouck, & Guarino, 2010; Spataro et al., 2011).…”

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.
