Background:
Post-translational modification of proteins by SUMO is critical for a wide range of cellular and developmental processes. Although SUMO proteins have been extensively studied in animals and, to some extent, in Arabidopsis, their precise functions in other crop plants are still largely unknown.
Results:
In this research, we identified 31 TaSUMO genes in genome of wheat. Phylogenetic tree unveiled that genes clustered into thirteen subfamilies. Chromosomal mapping unveiled the dispersal of 31 TaSUMO genes across 11 wheat chromosomes. The eleven pairs of duplicated gene were identified in the SUMO family. Ka/Ks ratio revealed that 8 duplicated TaSUMO genes went through purifying purification. Furthermore, it was noted that TaSUMO genes displayed significant conversation in their gene structure. In addition, analysis of promoters uncovered the presence of numerous cis-regulatory elements in the promoter region of the TaSUMO genes. The differential expression patterns were observed among TaSUMO family members across various tissues and in response to multifaceted stress conditions. Moreover, this investigation explored the miRNAs targeted to TaSUMO genes and expression profile in various tissues.
Conclusion:
Thus, the results of this study establish a strong basis for further investigation of the functions of TaSUMO genes across different tissues, developmental stages, phytohormone responses, and diverse stress in wheat.
