Testing Taxonomic Predictivity of Foliar and Tuber Resistance to Phytophthora infestans in Wild Relatives of Potato.
Potato late blight, caused by the oomycete phytopathogen Phytophthora infestans, is a devastating disease found in potato-growing regions worldwide. Long-term management strategies to control late blight include the incorporation of host resistance to predominant strains. However, due to rapid genetic changes within pathogen populations, rapid and recurring identification and integration of nov...
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 کاملMiR1918 enhances tomato sensitivity to Phytophthora infestans infection
Late blight of tomato is caused by the oomycete pathogen Phytophthora infestans. In our previous work, we identified and characterized a miR1918 in P. infestans (pi-miR1918), and showed that its sequence is similar to the sequence of tomato miR1918 (sly-miR1918). In this study, we used Arabidopsis thaliana pre-miR159a as a backbone to synthesize pi-miR1918 via PCR and mutagenesis. The artificia...
متن کاملAcquired 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 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.
