Genome-Wide Analysis of the Glutathione S-Transferase (GST) Genes and Functional Identification of MdGSTU12 Reveals the Involvement in the Regulation of Anthocyanin Accumulation in Apple.

ABSTRACT: Anthocyanins have essential biological functions, affecting the development of horticultural production. They are synthesized in the cytoplasm through flavonoid metabolic pathways and finally transported into vacuoles for storage. Plant glutathione S-transferases (GSTs) are multifunctional enzymes involved in anthocyanin transportation. In this study, we identified 38 GSTs from the apple (Malus domestica) genome (HFTH1 Whole Genome v1.0) based on the sequence similarity with the GST family proteins of Arabidopsis. These MdGST genes could be grouped into nine chief subclasses: U, F, L, Z, T, GHR, EF1Bγ, TCHQD, and DHAR. The structures, motifs, three-dimensional models, and chromosomal distribution of MdGST genes were further analyzed. Elements which are responsiv
