Enhanced Triacylglycerol Accumulation in Vegetative Tissues of Plants

摘要

In the tgd1-1 mutant that displays substantially enhanced TAG synthesis and turnover, disruption of SUGAR-DEPENDENT1 (SDP1) TAG lipase or PEROXISOMAL TRANSPORTER1 (PXA1) severely decreases FA turnover, leading to an increase in leaf TAG content up to 9% of dry weight and total leaf lipid by three-fold. The membrane lipid content and composition of tgd1-1 sdp1-4 and tgd1-1 pxa1-2 double mutants are altered and they are compromised in growth and development and fertility.
