Overexpression of BpERF1.1 in Betula Platyphylla enhanced tolerance to multiple abiotic stresses.

ABSTRACT: Cold, salt and drought are the main environmental stresses affecting plant growth and crop yield. ERF1, a member of the well-studied ERF gene family, has been proven to play an important role in abiotic stress in plants. In this study, an ERF1, BpERF1.1, was overexpressed in birch (Betula Platyphylla Suk.) and 11 transgenic lines were obtained. Effects of cold, salt and drought treatments were  checked  on the BpERF1.1 overexpressing lines and the corresponding WT line. The transgenic lines showed improved tolerance against these abiotic stresses than the WT line. Further RNA-seq analysis identified 689 differentially expressed genes (DEGs) in the transgenic birch compared with WT, including 228 up-regulated genes and 461 down-regulated genes. The result
