Increased stress tolerance in transgenic alfalfa expressing At. DREB1C gene by Agrobacterium-mediated genetic transformation

摘要

Abiotic stresses are multigenic as a quantitative trait in multiple signaling pathways (Knight and Knight, 2001).The transcription factor DREB can induce many genes related to stresses to express in order to regulate the stress responses of plants.The objectives of this study were that transferring dreb1c gene into alfalfa to improve its stress tolerance by A grobacterium-mediated genetic engineering and tissue cultural technology.
