متن کامل[Heteroplasmosis in Phytophthora infestans].
APCR and monozoospore plating was used to demonstrate a simultaneous presence of the mitochondria with mitochondrial DNA of haplotypes ILa and IIa in the mycelium of several Phytophthora infestans strains.
متن کاملInternuclear gene silencing in Phytophthora infestans.
Transformation of the diploid oomycete plant pathogen Phytophthora infestans with antisense, sense, and promoter-less constructs of the coding sequence of the elicitin gene inf1 resulted in transcriptional silencing of both the transgenes and the endogenous gene. Since heterokaryons obtained by somatic fusion of an inf1-silenced transgenic strain and a wild-type strain displayed stable gene sil...
متن کاملReproductive Strategies of Field Phytophthora Infestans Populations on Potato and Tomato in Some Regions of Russia
The occurrence of zoosporangia and oospores is analyzed for 88 field populations of Phytophthora infestans (Mont.) de Bary in Moscow region and other regions of Russia from 1997 to 2006. For estimation of zoosporangia and oospore frequencies in the populations, the indexes IZ (for zoosporangia) and IO (for oospores) are suggested. The combinations of these indexes enabled a reveal of 4 strategi...
متن کاملAccumulation and Resistance to Phytophthora infestans
Active oxygen species (AOS) are responsible for triggering defense responses in plants. Respiratory burst oxidase homologs ( rboh genes) have been implicated in AOS generation. We have isolated two rboh cDNAs, NbrbohA and NbrbohB , from Nicotiana benthamiana leaves. NbrbohA was expressed constitutively at a low level and the transcripts were increased after mechanical stress of control leaf inf...
