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.

“…They are induced by water deficit and fruit ripening (Iusem et al, 1993). Since then, many ASR homologous proteins have been cloned from a variety of plants (Cakir et al, 2003; Kalifa et al, 2004; Virlouvet et al, 2011; Hu et al, 2013; Zhang et al, 2015). ASR gene families are widely distributed in monocots, dicots, herbs, and xylophyta, but no ASR ortholog have been identified in Arabidopsis (Wong et al, 2006).…”

“…A wheat ASR gene, TaASR1 , increases drought and osmotic stress tolerance in transgenic tobacco by activating the antioxidant system and the expression levels of stress-responsive genes (Hu et al, 2013). Overexpression of banana ASR ( MaASR ) in Arabidopsis and rice ASRs ( OsASR1 and OsASR3 ) in rice has been shown to enhance drought and salt tolerance, respectively, in transgenic lines (Joo et al, 2013; Zhang et al, 2015). The loblolly pine ASR gene lp3 is induced by water deficit stress mediated by ABA (Padmanabhan et al, 1997).…”

Drought and other types of abiotic stresses negatively affect plant growth and crop yields. The abscisic acid-, stress-, and ripening-induced (ASR) proteins play important roles in the protection of plants against abiotic stress. However, the regulatory pathway of the gene encoding this protein remains to be elucidated. In this study, the foxtail millet (Setaria italica) ASR gene, SiASR4, was cloned and characterized. SiASR4 localized to the cell nucleus, cytoplasm and cytomembrane, and the protein contained 102 amino acids, including an ABA/WDS (abscisic acid/water-deficit stress) domain, with a molecular mass of 11.5 kDa. The abundance of SiASR4 transcripts increased after treatment with ABA, NaCl, and PEG in foxtail millet seedlings. It has been reported that the S. italica ABA-responsive DRE-binding protein (SiARDP) binds to a DNA sequence with a CCGAC core and that there are five dehydration-responsive element (DRE) motifs within the SiASR4 promoter. Our analyses demonstrated that the SiARDP protein could bind to the SiASR4 promoter in vitro and in vivo. The expression of SiASR4 increased in SiARDP-overexpressing plants. SiASR4-transgenic Arabidopsis and SiASR4-overexpressing foxtail millet exhibited enhanced tolerance to drought and salt stress. Furthermore, the transcription of stress-responsive and reactive oxygen species (ROS) scavenger-associated genes was activated in SiASR4 transgenic plants. Together, these findings show that SiASR4 functions in the adaption to drought and salt stress and is regulated by SiARDP via an ABA-dependent pathway.

Banana (Musa acuminata) is one of the most popular fresh fruits. However, the rapid spread of fungal pathogen Fusarium oxysporum f. sp. cubense (Foc) in tropical areas severely affected banana growth and production. Thus, it is very important to identify candidate genes involved in banana response to abiotic stress and pathogen infection, as well as the molecular mechanism and possible utilization for genetic breeding. Heat stress transcription factors (Hsfs) are widely known for their common involvement in various abiotic stresses and plant-pathogen interaction. However, no MaHsf has been identified in banana, as well as its possible role. In this study, genome-wide identification and further analyses of evolution, gene structure and conserved motifs showed closer relationship of them in every subgroup. The comprehensive expression profiles of MaHsfs revealed the tissue- and developmental stage-specific or dependent, as well as abiotic and biotic stress-responsive expressions of them. The common regulation of several MaHsfs by abiotic and biotic stress indicated the possible roles of them in plant stress responses. Taken together, this study extended our understanding of MaHsf gene family and identified some candidate MaHsfs with specific expression profiles, which may be used as potential candidates for genetic breeding in banana.
