Genome-wide identification of sucrose synthase gene family from Camellia sinensis and regulatory role of CsSUS3 in sucrose metabolism in post-harvest tea leaves.

ABSTRACT:

Background

Sucrose synthase (SUS), a crucial enzyme in the sucrose metabolism pathway, has synthesis and decomposition activities to promote the sucrose involved in plant growth and development, or stress response. SUS gene family members in more and more species have been identified and analyzed until now. However, the studies on SUS gene family and its functional characteristics in tea plant, is limited.

Results

Here, we identified seven SUS genes (CsSUS1-CsSUS7) from the genome of tea plant ('Tieguanyin'). These seven CsSUSs with similar genetic structures were distributed on five chromosomes. CsSUSs were classified into SUSI, SUSII, and SUSIII subgroups. In the CsSUSs promoter, cis-elements related to light, phytohormone, and stress were observed. Transcriptome or quanti
