“…Indeed, in vitro assays showed that tomato, plantain and lily ASR1 proteins can prevent enzyme denaturation after heating or freezing-thaw cycles. 26,30,31 On the other hand, ASR1 acts as a transcription factor. This proposed dual function is supported by ASR1 localization both in the nucleus and in the cytosol, 4,17,32,33 as well as by its role as a DNA-binding protein.…”

Abscisic acid (ABA)-, stress-, and ripening-induced (ASR) proteins are reported to be involved in abiotic stresses. However, it is not known whether ASR genes confer drought stress tolerance by utilizing the antioxidant system. In this study, a wheat ASR gene, TaASR1, was cloned and characterized. TaASR1 transcripts increased after treatments with PEG6000, ABA and H2O2. Overexpression of TaASR1 in tobacco resulted in increased drought/osmotic tolerance, which was demonstrated that transgenic lines had lesser malondialdehyde (MDA), ion leakage (IL) and reactive oxygen species (ROS), but higher relative water content (RWC) and superoxide dismutase (SOD) and catalase (CAT) activities than wild type (WT) under drought stress. Overexpression of TaASR1 in tobacco also enhanced the expression of ROS-related and stress-responsive genes under osmotic stress. In addition, transgenic lines exhibited improved tolerance to oxidative stress by retaining more effective antioxidant system. Finally, TaASR1 was localized in the cell nucleus and functioned as a transcriptional activator. Taken together, our results showed that TaASR1 functions as a positive factor under drought/osmotic stress, involved in the regulation of ROS homeostasis by activating antioxidant system and transcription of stress-associated genes.

“…The ASR gene family functionally participates in various abiotic stress signaling pathways (Iusem et al 1993;Konrad and Bar-Zvi 2008;Hsu et al 2011). Overexpression of tomato SlASR1 decreased rates of water loss during drought stress in tobacco (Ricardi et al 2014).…”

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.
