Computational and comparative analyses of 150 full-length cDNA sequences from the oomycete plant pathogen Phytophthora infestans.
Phytophthora infestans is a devastating phytopathogenic oomycete that causes late blight on tomato and potato. Recent genome sequencing efforts of P. infestans and other Phytophthora species are generating vast amounts of sequence data providing opportunities to unlock the complex nature of pathogenesis. However, accurate annotation of Phytophthora genomes will be a significant challenge. Most ...
متن کاملMating type distribution and pathogenicity of Phytophthora infestans in Taiwan
Taiwanese isolates of Phytophthora infestans were examined for mating types and pathogenicity to tomato and potato. A total of 70 isolates, including 68 isolates from tomato and 2 isolates from potato, from six counties of Taiwan were all A1 mating type. Three tomato isolates of P. infestans caused only leaf blight of tomato, while two isolates obtained from potato were able to cause the diseas...
متن کاملAntifungal activity of oosporein from an antagonistic fungus against Phytophthora infestans.
An antifungal metabolite, oosporein, was isolated from the culture of Verticillium psalliotae that produced the antagonistic effects on Phytophthora infestans. Oosporein exhibited a significant growth-inhibitory effect on P. infestans in comparison with other phytopathogenic fungi.
متن کاملPhytophthora infestans Has a Plethora of Phospholipase D Enzymes Including a Subclass That Has Extracellular Activity
In eukaryotes phospholipase D (PLD) is involved in many cellular processes. Currently little is known about PLDs in oomycetes. Here we report that the oomycete plant pathogen Phytophthora infestans has a large repertoire of PLDs divided over six subfamilies: PXPH-PLD, PXTM-PLD, TM-PLD, PLD-likes, and type A and B sPLD-likes. Since the latter have signal peptides we developed a method using meta...
متن کاملArabidopsis late blight: infection of a nonhost plant by Albugo laibachii enables full colonization by Phytophthora infestans
The oomycete pathogen Phytophthora infestans causes potato late blight, and as a potato and tomato specialist pathogen, is seemingly poorly adapted to infect plants outside the Solanaceae. Here, we report the unexpected finding that P. infestans can infect Arabidopsis thaliana when another oomycete pathogen, Albugo laibachii, has colonized the host plant. The behaviour and speed of P. infestans...
