Differential Expression Analysis of Boron Transporters and Some Stress-Related Genes in Response to 24-Epibrassinolide and Boron by Semi-Quantitative RT-PCR in Arabidopsis Thaliana (L.) Heynh

Abstract

Plant steroidal hormones, brassinosteroids (BRs), promote plant developmental processes and enhance tolerance to several abiotic stresses including high boron (B) stress. To examine the possible role of BR in high B-induced stress at the transcriptional level, we investigated the response of B transporter genes (BOR1-4), high B-induced genes (MATE, Hsp-like), BR-induced genes (Hsp70-4, Hsp90-1) and other stress-related genes (LTI/COR78, LEA4-5) upon exogenous treatments of 24-epibrassinolide (EBL) on Arabidops…
