Whole and partial genome sequences are becoming available at an ever-increasing pace. For many plant pathogen systems, we are moving into the era of genome resequencing. The first Phytophthora genomes, P. ramorum and P. sojae, became available in 2004, followed shortly by P. infestans in 2006. Availability of whole genome sequences has provided rapid and immediate advances in several areas also...
Phosphatidylcholine, labeled by two fluorescent fatty acids, was fed to cultured plant cells (Petrosilenum crispum, L.; VBI-0, Nicotiana benthiana, L.) and fluorescent diacylglycerol (DAG) was the major metabolite. When a glycoprotein elicitor, derived from Phytophthora sojae, was applied to the parsley cells and the small protein cryptogein from Phytophthora cryptogea was applied to the tobacc...
سویا glycine max (l.) merr. گیاهی است از خانواده بقولات و یکی از مهمترین دانه های روغنی جهان محسوب می شود. یکی از عوامل محدودکننده کشت سویا، بیماری پوسیدگی ریشه و طوقه است. با توجه به ماهیت عامل بیماری که خاکزاد می باشد مبارزه شیمیایی نه تنها نمی تواند کاملاً موثر باشد بلکه باعث تخریب محیط زیست نیز می گردد. در این بررسی اثر جدایه های مختلف تریکودرما بر phytophthora sojae در دو بخش آزمون ه...

There is emerging evidence that the proteolytic machinery of plants plays important roles in defense against pathogens. The oomycete pathogen Phytophthora infestans, the agent of the devastating late blight disease of tomato (Lycopersicon esculentum) and potato (Solanum tuberosum), has evolved an arsenal of protease inhibitors to overcome the action of host proteases. Previously, we described a...
PsSAK1, a mitogen-activated protein (MAP) kinase from Phytophthora sojae, plays an important role in host infection and zoospore viability. However, the downstream mechanism of PsSAK1 remains unclear. In this study, the 3'-tag digital gene expression (DGE) profiling method was applied to sequence the global transcriptional sequence of PsSAK1-silenced mutants during the cysts stage and 1.5 h aft...
Isoflavone reductase (IFR) is an enzyme involved in the biosynthetic pathway of isoflavonoid phytoalexin in plants. IFRs are unique to the plant kingdom and are considered to have crucial roles in plant response to various biotic and abiotic environmental stresses. Here, we report the characterization of a novel member of the soybean isoflavone reductase gene family GmIFR. Overexpression of GmI...
Several plant pathogenic fungi affect soybean plant health at different growth stages (Table 1). Although infection may occur early, many of these pathogens do not cause apparent symptoms until later growth stages. Frequently seedling health is ignored because plant populations are acceptable and stem and leaves do not express symptoms during early vegetative growth. Phytophthora sojae, Pythium...
SUMMARY Transcripts encoding elicitin-like protein domains were identified from similarity searches of Phytophthora sojae expressed sequence tags and were characterized with regard to molecular structure and elicitor activity. The P. sojae elicitin family consists of at least nine genes with products similar to previously described elicitins (SOJA-2, SOJB, SOJ2, SOJ3, SOJ5, SOJ6 and SOJ7) or hi...
