Random 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 کاملLipoxygenase gene expression in the tobacco-Phytophthora parasitica nicotianae interaction.
A recently isolated cDNA clone of tobacco (Nicotiana tabacum L.) lipoxygenase (LOX) was used to study LOX gene expression in tobacco cell-suspension cultures and intact plants in response to infection with Phytophthora parasitica nicotianae (Ppn). Southern blot analysis of tobacco DNA indicated that only a small number of LOX genes hybridize to this probe. These genes were not constitutively ex...
متن کاملNa+/H+ exchanger 1 participates in tobacco disease defence against Phytophthora parasitica var. nicotianae by affecting vacuolar pH and priming the antioxidative system
Despite the importance of NHX1 (Na(+)/H(+) exchanger 1) in plant salt tolerance, little is known about its other functions. In this study, intriguingly, it was found that NHX1 participated in plant disease defence against Phytophthora parasitica var. nicotianae (Ppn) in Nicotiana benthamiana. NbNHX1 was originally isolated from N. benthamiana, and characterized. The subcellular localization of ...
متن کاملIN VITRO EVALUATION OF Trichoderma spp. AGAINST Phytophthora nicotianae
Si ngh A, Islam MN (2010) In vitro evaluation of Trichoderma spp against Phytophthora nicotianae. Int. J. Expt. Agric. 1(1), 20-25. The Blank sank disease of tobacco caused by Phytophthora nicotianae results in considerable loss of the crop. This lab study aimed to investigate antagonistic activity of Trichoderma spp isolates against P. nicotianae. Three isolates of Trichoderma harzianum and on...
متن کاملChemical characterization of α hormones of Phytophthora parasitica
A method for the large scale hormone α1 and α2 extraction from agar cultures of A1 and A2 mating types of Phytophthora parasitica has been developed. Using a total of 240 L of organic solvents to extract 40 L of the agar medium, sufficient amounts of α hormones were obtained to permit characterization of their physical and chemical properties. Activities of both hormones were in the neutral fra...
