Quantitative proteomic analysis of Arabidopsis thaliana with different levels of phospholipid:diacylglycerol acyltransferase1 expression.

ABSTRACT:

Background

Phospholipid:diacylglycerol acyltransferase1 (PDAT1) enzyme is known to play an important role in lipid metabolism. Initially, it was suggested that the construction of PDAT1 overexpressors may result in plant varieties with increased oil content. Contrary to those expectations, Arabidopsis thaliana lines overexpressing AtPDAT1 did not exhibit an increased accumulation of the triacylglycerol pool. However, the overexpressing lines exhibited accelerated growth rate, increased seed yield, and when subjected to cold treatments, they had greater thermotolerance, whereas knock-out line were more susceptible than the wild-type.

Result

In this work, we have performed a comparative proteomic analysis among wild-type, AtPDAT1-overexpressing and knock-out lines of Arabidops
