MODIFICATION OF PLANT PHENOTYPES THROUGH TOR GENE EXPRESSION

摘要

Broad experimental tools that include biochemical, molecular, developmental, global genomics and loss and gain of function transgenic approaches have been applied to address target of rapamycin (TOR) signaling pathway in plants, especially using Arabidopsis model system and Brassica napus crop Towards this objective, putative TOR interacting proteins (TIPs) have been identified and functions of these implicated in diverse developmental and biochemical processes have been investigated Functional studies including over-expression and silencing of TOR and TIPs have shown a range of phenotypes that include embryo defective nutrition-use-efficiency, water-use-efficiency and stress resistance in transgenic Arabidopsis and Brassica lines Some of these phenotypes are relevant to important developmental pathways implicated in canola crop yield and performance.
