| Title | <i>OsHsfB4b</i> Confers Enhanced Drought Tolerance in Transgenic Arabidopsis and Rice. | |
|
Abstract: Heat shock factors (Hsfs) play pivotal roles in plant stress responses and confer stress tolerance. However, the functions of several <i>Hsfs</i> in rice (<i>Oryza sativa</i> L.) are not yet known. In this study, genome-wide analysis of the <i>Hsf</i> gene family in rice was performed. A total of 25 <i>OsHsf</i> genes were identified, which could be clearly clustered into three major groups, A, B, and C, based on the characteristics of the sequences. Bioinformatics analysis showed that tandem duplication and fragment replication were two important driving forces in the process of evolution and expansion of the <i>OsHsf</i> family genes. Both <i>OsHsfB4b</i> and <i>OsHsfB4d</i> showed strong responses to the stress treatment. The results of subcellular localization showed that the OsHsfB4b protein was in the nucleus whereas the OsHsfB4d protein was located in both the nucleus and cytoplasm. Over-expression of the <i>OsHsfB4b</i> gene in Arabidopsis and rice can increase the resistance to drought stress. This study provides a basis for understanding the function and evolutionary history of the <i>OsHsf</i> gene family, enriching our knowledge of understanding the biological functions of <i>OsHsfB4b</i> and <i>OsHsfB4d</i> genes involved in the stress response in rice, and also reveals the potential value of <i>OsHsfB4b</i> in rice environmental adaptation improvement. |
