The Loricrin-Like Protein (LLP) of Phytophthora infestans Is Required for Oospore Formation and Plant Infection
Loricrin-like protein (LLP) is characterized by a high content of glycine residues and is a major component of plant cell wall. Here, we identified a Phytophthora infestans ortholog of plant LLP, named PiLLP. In P. infestans, PiLLP is strongly expressed in asexual and sexual developmental stages, including in sporangia, zoospores and germinating cysts, and during oospore formation, as well as i...
متن کاملOccurrence of Oospores of Phytophthora Infestans in the Field and under Controlled Conditions
Both A1 and A2 mating types of Phytophthora infestans were detected in El-Behera governorate and the surrounding area where potato and tomato were intensively cultivated during the 2005-2006 growing season. The A2 mating type constituted 14.8% of the total isolates recovered (162) while A1 mating type constituted 83.9%. A 7.4% of the total potato and tomato fields (94) surveyed yielded A2 matin...
متن کاملSmall RNAs in Phytophthora infestans and cross-talk with potato
Small RNAs (sRNAs) are small non-coding RNAs usually ranging in size 20-30 nt. They are playing important roles in plant-pathogen interactions. This thesis aimed at studying the sRNA populations in potato and Phytophthora infestans and their role in the potato-P. infestans interaction. An attempt was also made to implement such knowledge to improve resistance in potato against P. infestans. P. ...
متن کاملCellulose synthesis in Phytophthora infestans is required for normal appressorium formation and successful infection of potato.
Cellulose, the important structural compound of cell walls, provides strength and rigidity to cells of numerous organisms. Here, we functionally characterize four cellulose synthase genes (CesA) in the oomycete plant pathogen Phytophthora infestans, the causal agent of potato (Solanum tuberosum) late blight. Three members of this new protein family contain Pleckstrin homology domains and form a...

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.
