Characterization of color variation in bamboo sheath of Chimonobambusa hejiangensis by UPLC-ESI-MS/MS and RNA sequencing.

ABSTRACT:

Background

Chimonobambusa hejiangensis (C.hejiangensis) is a high-quality bamboo species native to China, known for its shoots that are a popular nutritional food. Three C.hejiangensis cultivars exhibit unique color variation in their shoot sheaths, however, the molecular mechanism behind this color change remains unclear.

Methods

We investigated flavonoid accumulation in the three bamboo cultivar sheaths using metabolomics and transcriptomics.

Results

UPLC-MS/MS identified 969 metabolites, with 187, 103, and 132 having differential accumulation in the yellow-sheath (YShe) vs. spot-sheath (SShe)/black-sheath (BShe) and SShe vs. BShe comparison groups. Flavonoids were the major metabolites that determined bamboo sheath color through differential accumulation of metabol
