Sedum Peltatum (crassulaceae): a New Species from Anhui, China
Sedum peltatum M.L. Chen et X.H. Cao, belonging to the family Crassulaceae DC., is described and illustrated from China as a new species. It was collected from Nanwu canyon, Huangnikeng valley, Gaokeng valley and Qingshikeng valley in the Jiulong Mountains, China (P. R.). Morphological diagnostic characters of closely related species are also discussed. Introduction Sedum L. is the largest and ...
متن کاملA Genetic Transformation Method for Cadmium Hyperaccumulator Sedum plumbizincicola and Non-hyperaccumulating Ecotype of Sedum alfredii
The present study demonstrates the development of an Agrobacterium-mediated genetic transformation method for species of the Sedum genus, which includes the Cd/Zn hyperaccumulator Sedum plumbizincicola and the non-hyperaccumulating ecotype of S. alfredii. Multiple shoots were induced from stem nodes of two Sedum plants using Murashige and Skoog (MS) medium containing 0.1 mg/L cytokinin 6-benzyl...
متن کاملSedum Acre Embryogenesis: Polyploidization in the Suspensor
Cytological processes of differentiation in the embryo suspensor of Sedum acre L. were compared with the development of the embryo proper. The zygote undergoes an asymmetric division to produce an apical cell and a basal cell, which becomes the basal cell of the suspensor. The mature differentiated suspensor consists of a large haustorial basal cell and 3–4 chalazal cells. The basal cell nucleu...
متن کاملMyricitrin Protects Cardiomyocytes from Hypoxia/Reoxygenation Injury: Involvement of Heat Shock Protein 90
Modulation of oxidative stress is therapeutically effective in ischemia/reperfusion (I/R) injury. Myricitrin, a naturally occurring phenolic compound, is a potent antioxidant. However, little is known about its effect on I/R injury to cardiac myocytes. The present study was performed to investigate the potential protective effect of myricitrin against hypoxia/reoxygenation (H/R)-induced H9c2 ca...
متن کاملNew Adducts of Iriflophene and Flavonoids Isolated from Sedum aizoon L. with Potential Antitumor Activity.
Four new special compounds with character of an iriflophene unit and a flavonoid unit connecting via a furan ring were isolated from the roots of Sedum aizoon L. Their corresponding structures were elucidated on the basis of spectroscopic analysis. The in vitro anti-proliferative activities against BXPC-3, A549, and MCF-7 tumor cell lines were evaluated. Compounds 3 and 4 exhibited moderate cyt...
