The L-type Ca2+ Channel Blocker Nifedipine Inhibits Mycelial Growth, Sporulation, and Virulence of Phytophthora capsici
The oomycete vegetable pathogen Phytophthora capsici causes significant losses of important vegetable crops worldwide. Calcium and other plant nutrients have been used in disease management of oomycete pathogens. Calcium homeostasis and signaling is essential for numerous biological processes, and Ca(2+) channel blockers prevent excessive Ca(2+) influx into the fungal cell. However, it is not k...
متن کاملPhytophthora ×stagnum nothosp. nov., a New Hybrid from Irrigation Reservoirs at Ornamental Plant Nurseries in Virginia
A novel Phytophthora species was frequently recovered from irrigation reservoirs at several ornamental plant production facilities in eastern Virginia. Initial sequencing of the internal transcribed spacer (ITS) region of this species generated unreadable sequences due to continual polymorphic positions. Cloning and sequencing the ITS region as well as sequencing the mitochondrially encoded cyt...
متن کاملRandom amplified polymorphic DNA analysis of China isolates of Phytophthora parasitica var. nicotianae from different districts
China isolates of Phytophthora parasitica var. Nicotianae have been divided into three large pathogenic groups (PGS) (Hv(A), Iv(B), Wv(C)) which came from Yunnan, Shandong and Liaoning. These three districts belong to main tobacco regions in China: 15 isolates derived from Yunnan of the southwest, 13 isolates from Shandong of the east and 20 isolates from Liaoning of the northeast. PGS were det...
متن کاملGenotyping Phytophthora ramorum Isolates From Nurseries in the United States Using PCR- RFLP and Microsatellite Analyses
The risk of introducing the important plant pathogen Phytophthora ramorum outside of its present natural range is of extreme concern; however, the detection of P. ramorum in U.S. nurseries is increasing. The USDA has confirmed the presence of P. ramorum in nurseries in 21 states that received plants from an infested, southern California nursery and others. This nursery produces approximately 15...
متن کاملZoospore exudates from Phytophthora nicotianae affect immune responses in Arabidopsis
Zoospore exudates play important roles in promoting zoospore communication, homing and germination during plant infection by Phytophthora. However, it is not clear whether exudates affect plant immunity. Zoospore-free fluid (ZFF) and zoospores of P. nicotianae were investigated comparatively for effects on resistance of Arabidopsis thaliana Col-0 and mutants that affect signaling mediated by sa...
