Brassica napus Transcription Factor Bna.A07.WRKY70 Negatively Regulates Leaf Senescence in Arabidopsis thaliana.

ABSTRACT: Leaf senescence is the final stage of leaf development and is essential for storage properties and crop productivity. WRKY transcription factors have been revealed to play crucial roles in several biological processes during plant growth and development, especially in leaf senescence. However, the functions of Brassica napus WRKY transcription factors in leaf senescence remain unclear. In the present study, Bna.A07.WRKY70, one paralogue of Brassica napus WRKY70, was cloned from the B. napus cultivar "Zhongshuang11 (ZS11)". We found that Bna.A07.WRKY70 contains a highly conserved WRKY domain and is most closely related to Arabidopsis thaliana WRKY70. The subcellular localization and transcriptional self-activation assays indicated that Bna.A07.WRKY70 funct
