BACKGROUND Pectate lyases depolymerize pectins by catalyzing the eliminative cleavage of alpha-1,4-linked galacturonic acid. Pectate lyase-like (PLL) genes make up among the largest and most complex families in plants, but their cellular and organismal roles have not been well characterized, and the activity of these genes has been assessed only at the(More)
Leaf coloration is one of the most important and attractive characteristics of Ananas comosus var. bracteatus. The chimeric character is not stable during the in vitro tissue culturing. Many regenerated plants lost economic values for the loss of the chimeric character of leaves. In order to reveal the molecular mechanisms involved in the albino phenotype(More)
The red-leaf coloration of Quanhong poplar (QHP) (Populus deltoides), resulting from a bud sport, is a distinctive trait conferring high ornamental value. However, the underlying molecular coloration mechanism of the red-leaf poplar remains unknown. In this study, tissue buds and leaves from mutant QHP(red)and its wild-type progenitor L2025 (green) were(More)
The worsening of Cadmium (Cd) pollution has intensified the urban ecological environment deterioration in the world. Purifying contaminated environment using the tall, colored-leaf woody plants has been proved as an aesthetically pleasing approach. However, the effects of Cd stress on colored-leaf woody plants have been little reported. Present hydroponic(More)
