Genome-wide identification and characterization of SRO gene family in wheat : Molecular evolution and expression profiles during different stresses

SRO (SIMILAR TO RCD ONE), a type of plant-specific small protein family, play important roles in plant growth and development, as well as in response to biotic/abiotic stresses. Although characterization of SROs have been performed in model plants, little is known about their function in wheat, especially under stress conditions. In this study, 30 SRO genes were identified from the wheat genome (TaSRO). They were phylogenetically separated into two groups with distinct structures. The cis-regulatory elements in the promoter region of TaSROs were analyzed and numerous elements functionally associated with stress responding and hormones were interpreted, implying the reason for induction expression patterns of TaSROs during abiotic and biotic stresses in wheat. Whole-genome replication events in the SRO gene family of wheat and seven other species (Arabidopsis thaliana, rice, maize, barley, soybean, upland cotton, and cucumber) were analyzed, resulting in 1, 12, 9, 23, 6, 5, and 3 of gene pairs, respectively. The tissue-specific expression pattern profiling revealed that most TaSROs are highly expressed in one or more tissues and may play an important role in wheat growth and development. In addition, qRT-PCR results further confirmed that these TaSRO genes are involved in wheat stress response. In summary, our study laid a theoretical basis for molecular function deciphering of TaSROs, especially in plant hormones and biotic/abiotic stress responses.
