Acetylome analyses in the germinating rice seed


ABSTRACT: Seed germination is a complicated physiological process, during which structures of mitochondria and plastids are recovered, and metabolisms are re-activated (Han and Yang, 2015). It has been shown that metabolism reactivation is very important for rice germination (He et al., 2011b;Han et al., 2014a). It is still unknown if protein acetylation involved in and regulate these metabolisms during rice seed germination. To answer this question, we globally profiled the acetylome in rice embryos from the germinating seeds. A number of acetylated enzymes were identified. The results provide more information about the metabolism regulation in germinating seeds.

Regulation of rice seed germination has been shown to mainly occur at post-transcriptional levels, of which the changes on proteome status is a major one. Lysine acetylation and succinylation are two prevalent protein post-translational modifications (PTMs) involved in multiple biological processes, especially for metabolism regulation. To investigate the potential mechanism controlling metabolism regulation in rice seed germination, we performed the lysine acetylation and succinylation analyses  ...[more]
