转录组学分析揭示红甜菜(Beta vulgaris L)萜类化合物生物合成的发育调控机制OA

Terpenoids are key bioactive compounds that influence plant growth,stress resistance,and nutritional quality.However,the developmental regulatory mechanism of terpenoid biosynthesis in red beet(Beta vulgaris L.)remains unclear.In this study,transcriptomic analysis was employed to elucidate the dynamics of terpenoids at two key developmental stages(RG2 and RG3).Transcriptome sequencing identified 21 genes associated with terpenoid biosynthesis,including the rate-limiting enzymes BvDXS(MEP pathway)and BvHMGR(MVA pathway).With the exception of the upregulation of BvDXS1 and BvHDS,most genes in the MVA and MEP pathways were downregulated at the RG3 stage.This study provides candidate genes for investigating the mechanism of terpenoid accumulation in red beet.
