Anthocyanin metabolites and related regulatory genes analysis in leaves of Acer Pseudosieboldianum mutant during different periods of color change.

Background: Acer pseudosieboldianum (Pax) Komarov, is a colorful leaf species belonging to the family Aceraceae, mainly distributed in Northeast China, Russia, and northern Korea. The leaves of Acer pseudosieboldianum are green in spring and summer, and turning red in autumn, which is of high ornamental value. In previous study, a mutant maple was selected with alternating red-green leaf color in spring and summer.

De novo transcriptome revealed genes involved in anthocyanin biosynthesis, transport, and regulation in a mutant of Acer pseudosieboldianum.

Background: Acer pseudosieboldianum is a kind of excellent color-leafed plants, and well known for its red leaves in autumn. At the same time, A. pseudosieboldianum is one of the native tree species in the northeast of China, and it plays an important role in improving the lack of color-leafed plants in the north.

De novo transcriptome sequencing and anthocyanin metabolite analysis reveals leaf color of Acer pseudosieboldianum in autumn.

Background: Leaf color is an important ornamental trait of colored-leaf plants. The change of leaf color is closely related to the synthesis and accumulation of anthocyanins in leaves. Acer pseudosieboldianum is a colored-leaf tree native to Northeastern China, however, there was less knowledge in Acer about anthocyanins biosynthesis and many steps of the pathway remain unknown to date.
