Molecular mechanism of the extended oil accumulation phase contributing to the high seed oil content for the genotype of tung tree (Vernicia fordii).

ABSTRACT:

Background

Oil from seeds of the tung tree (Vernicia fordii) has unique drying properties that are industrially important. We found that the extended oil accumulation period was related to the high seed oil content at maturity among tung tree population. In order to understand the molecular mechanism underlying the high oil content in tung tree seed, Tree H and L were adopted for the further investigation, with seed oil content of about 70 and 45%, respectively. We compared the transcriptomic changes of seed at various times during oil accumulation between the two trees.

Results

Transcriptomes analysis revealed that many genes involved in glycolysis, fatty acid synthesis, and tri-acyl glyceride assembly still kept high expression in the late period of seed oil accumulation f
