Abstract

is a characteristic rare economic tree species in subtropical mountainous areas. The kernels of have rich content of organic acids, and malate is the predominant organic acid in kernels. However, the contents, biosynthesis/metabolism pathway and transcriptional regulation of malate in developing kernels remain completely unknown. Here, the organic acid composition in developing kernels was first analyzed. The results showed that the content of malate was increased during the maturation kernels. A malate synthase (TgMLS) gene might be involved in the accumulation of malate based on transcriptome data, gene expression and enzyme activity analysis. Transient expression of in tobacco resulted in the high malate synthase activity and malate content. Furthermore, a basic helix-loop-helix transcription factor (bHLH), TgbHLH87 was identified to positively regulate the expression via directly binding the promoter. Our finding contributes to mechanism underlying malate accumulation in kernels.
