Genetic enhancement of fatty acid synthesis by targeting rat liver ATP:citrate lyase into plastids of tobacco.

abstract：:Brassinosteroids (BRs) are a class of steroid hormones regulating multiple aspects of plant growth, development, and adaptation. Compared with extensive studies in Arabidopsis (Arabidopsis thaliana), the mechanism of BR signaling in rice (Oryza sativa) is less understood. Here, we identified OsWRKY53, a transcription ...
