Biphenyl Phytoalexin in Sorbus pohuashanensis Suspension Cell Induced by Yeast Extract.
Biphenyls are unique phytoalexins de novo synthesized in plants in response to pathogen attack. These compounds are found in Maloideae, a subfamily of the Rosaceae. The anti-microbial activities of biphenyls have been reported in a number of studies and they appear to represent an important defense strategy against pathogens common in the Maloideae, such as species in Malus, Pyrus, Sorbus, and ...
متن کاملInhibition of phytoalexin biosynthesis in elicitor-treated tobacco cell-suspension cultures by calcium/calmodulin antagonists.
A role for calcium/calcium-binding proteins in a mechanism of signaling elicitor-inducible phytoalexin biosynthesis was investigated. Two classes of calcium/calmodulin antagonists, phenothiazines and naphthalenesulfonamides, inhibited sesquiterpene phytoalexin accumulation in tobacco (Nicotiana tabacum) cell-suspension cultures when added 1 h before elicitor. The antagonists also inhibited the ...
متن کاملDe novo transcriptomic analysis and development of EST-SSRs for Sorbus pohuashanensis (Hance) Hedl.
Sorbus pohuashanensis is a native tree species of northern China that is used for a variety of ecological purposes. The species is often grown as an ornamental landscape tree because of its beautiful form, silver flowers in early summer, attractive pinnate leaves in summer, and red leaves and fruits in autumn. However, development and further utilization of the species are hindered by the lack ...

The accumulation of phytoalexins against microbial attacks is one of the im portant defense responses in higher plants [1, 2], The induction of the phytoalexins which is triggered after the recog nition of signal materials “elicitors” by plant cells is initiated at the transcription level of specific genes. Synthesis of specific enzymes results in the de novo activation of a secondary metaboli...
