摘要: Glutaredoxins (GRXs) are a class of small oxidoreductases which modulate various biological processes in plants. Here, we isolated a GRX gene from the rubber tree (Hevea brasiliensis Mull. Arg.), named as HbSRGRX1, which encoded 107 amino acid residues with a CPYC active site. Phylogenetic analysis displayed that HbSRGRX1 was more correlated with GRXs from Manihot esculenta Crantz. and Ricinus communis L. HbSRGRX1 was localized in the nuclei of tobacco cells, and its transcripts were preferentially expressed in male flowers and in the high-yield variety Reyan 7-33-97 with strong resistance against cold. The expression levels of HbSRGRX1 significantly decreased in tapping panel dryness (TPD) trees. Furthermore, HbSRGRX1 was regulated by wounding, hydrogen peroxide (H2O2), and multiple hormones. Altogether, these results suggest important roles of HbSRGRX1 in plant development and defense response to TPD and multiple stresses.
