摘要： Abscisic acid (ABA)-stress-ripening, or ABA-, stress-, and ripening-induced (ASR) proteins play an important role in responses to environmental stimuli. A total of ten barley HvASRs were identified in this study, which were unevenly distributed on three chromosomes. ASRs from barley, wheat, Brachypodium distachyon, rice, maize, foxtail millet, and tomato were classified into two distinct clusters based on phylogenetic analysis. Notably, ASRs from Poaceae were evenly distributed between these two clusters. HvASRs contained a typical ABA/WDS domain, and exhibited similar motif arrangements. Two gene pairs of tandem duplicates (HvASR4/5/6/7 and HvASR8/9) were identified among HvASRs. Cis-acting elements involved in hormone and stress responses, including ABRE, MYB, ARE, and STRE, were consistently identified in the promoters of HvASRs. The expression of HvASRs was substantially influenced by salt, osmotic, and ABA treatments in the roots and leaves of barley seedlings. HvASR2 acts as a transcriptional repressor, whereas HvASR3 serves as a transcriptional activator. These results enhance our understanding of the HvASR family and provide a foundation for further functional characterization.
