Unraveling the malate biosynthesis during development of Torreya grandis nuts.

ABSTRACT: Torreya grandis is a characteristic rare economic tree species in subtropical mountainous areas. The kernels of T. grandis have rich content of organic acids, and malate is the predominant organic acid in T. grandis kernels. However, the contents, biosynthesis/metabolism pathway and transcriptional regulation of malate in developing T. grandis kernels remain completely unknown. Here, the organic acid composition in developing T. grandis kernels was first analyzed. The results showed that the content of malate was increased during the maturation T. grandis 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 TgMLS<
