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)
DREB1 of the AP2/ERF superfamily plays a key role in the regulation of plant response to low temperatures. In this study, a novel DREB1/CBF transcription factor, PnDREB1, was isolated from Iceland poppy (Papaver nudicaule), a plant adaptive to low temperature environments. It is homologous to the known DREB1s of Arabidopsis and other plant species. It also(More)
China is known as a major distribution center for the genus Primula, with a total account of 300 species out of the 430 species reported in the world. Western Sichuan is considered as an important area of diversity of Primula, approximately accounting for 40 % of the total found in the country. This paper focused on the distribution, classification, and(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)
Sulfur dioxide (SO2), a major air pollutant in developing countries, is highly toxic to plants. To achieve better air quality and landscape, planting appropriate grass species in severe SO2 polluted areas is very critical. Cynodon dactylon, a widely used warm season turfgrass species, has good SO2-tolerant ability. In this study, we selected 9 out of 38 C.(More)
In this paper, the sensitivity of food spoilage organisms (Bacillus cereus; Escherichia coli) to natural antimicrobial peptides (surfactin; polylysine; nisin) from microorganism was observed, and the optimization of antimicrobial effect in meat evaluated by a RSM was studied. Results showed that these strains were sensitive to them. MICs of surfactin and(More)
