Novel insight into anthocyanin metabolism and molecular characterization of its key regulators in Camellia sasanqua.

Flower color is a trait that affects the ornamental value of a plant. Camellia sasanqua is a horticultural plant with rich flower color, but little is known about the regulatory mechanism of color diversity in this plant. Here, the anthocyanin profile of 20 C.

The complete chloroplast genome of Craib 1914, an economically valuable oil crop.

Craib 1914 is an industrially valuable oil crop from southern China for which little genetic information is available. Here, we found that its complete chloroplast genome is a circular sequence (156,905 bp) with a large single-copy region (LSC) of 67,724 bp, a small single copy region (SSC) of 18,400 bp, and two inverted repeats (IRs). In total, 130 genes were identified, including 86 protein-coding genes, 36 transfer RNAs, and 8 rRNA genes.

Functional analyses of a flavonol synthase-like gene from Camellia nitidissima reveal its roles in flavonoid metabolism during floral pigmentation.

The flavonoids metabolic pathway plays central roles in floral coloration, in which anthocyanins and flavonols are derived from common precursors, dihydroflavonols. Flavonol synthase (FLS) catalyses dihydroflavonols into flavonols, which presents a key branch of anthocyanins biosynthesis. The yellow flower of Camellia nitidissima Chi.
