Phytophthora nicotianae is a devastating oomycete plant pathogen with wide host range. On tobacco, it causes black shank, disease that can result in severe economic losses. Deployment of resistance one the most effective means controlling tobacco but adaptation to complete and partial by P. limit long-term effectiveness resistance. The molecular basis largely unknown. RNAseq was performed on tw...
Antalya province is the main center of vegetable production in Türkiye. Tomato comes first terms crops cultivated under greenhouse. Phytophthora species causing root and crown rot are among factors negatively affecting tomato yield quality. This research aimed to determine prevalence tomatoes grown identify disease. During surveys performed 170 greenhouses, plant soil samples were taken from ar...
گونهی بیمارگر گیاهی Phytophthora melonis از نظر ریختشناختی به برخی گونههای بدون پستانک جنس Phytophthora بهخصوص P. drechsleri شباهت دارد وبنابراین تفکیک این آرایههای همگرا دشوار است. این پژوهش به منظور طراحی آغازگرهای اختصاصی P. melonis بر اساس ژنوم هستهای و میتوکندریایی، بررسی اختصاصیت آنها در برابر سایر گونههای همگرا، و بهینهسازی استفاده از این آغا...
Secretion of pathogen proteins is crucial for the establishment of disease in animals and plants. Typically, early interactions between host and pathogen trigger regulated secretion of pathogenicity factors that function in pathogen adhesion and host penetration. During the onset of plant infection by spores of the Oomycete, Phytophthora nicotianae, proteins are secreted from three types of cor...
Agathosma species, which are indigenous to South Africa, are also cultivated for commercial use. Recently growers experienced severe plant loss, and symptoms shown by affected plants suggested that a soilborne disease could be the cause of death. A number of Phytophthora taxa were isolated from diseased plants, and this paper reports their identity, mating type, and pathogenicity to young Agath...
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...
