Acquired Resistance to Mefenoxam in Sensitive Isolates of Phytophthora infestans.
The systemic fungicide mefenoxam has been important in the control of late blight disease caused by Phytophthora infestans. This phenylamide fungicide has a negative effect on the synthesis of ribosomal RNA; however, the genetic basis for inherited field resistance is still not completely clear. We recently observed that a sensitive isolate became tolerant after a single passage on mefenoxam-co...
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...
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 کاملMultiple recognition of RXLR effectors is associated with nonhost resistance of pepper against Phytophthora infestans
Nonhost resistance (NHR) is a plant immune response to resist most pathogens. The molecular basis of NHR is poorly understood, but recognition of pathogen effectors by immune receptors, a response known as effector-triggered immunity, has been proposed as a component of NHR. We performed transient expression of 54 Phytophthora infestansRXLR effectors in pepper (Capsicum annuum) accessions. We u...
متن کاملVariation in Capsidiol Sensitivity between Phytophthora infestans and Phytophthora capsici Is Consistent with Their Host Range
Plants protect themselves against a variety of invading pathogenic organisms via sophisticated defence mechanisms. These responses include deployment of specialized antimicrobial compounds, such as phytoalexins, that rapidly accumulate at pathogen infection sites. However, the extent to which these compounds contribute to species-level resistance and their spectrum of action remain poorly under...
