Several species of Septoria are associated with leaf and fruit spot of pistachio (Pistacia vera), though their identity has always been confused, making identification problematic. The present study elucidates the taxonomy of the Septoria spp. associated with pistachio, and distinguishes four species associated with this host genus. Partial nucleotide sequence data for five gene loci, ITS, LSU,...
انگومک یا گموز مهمترین بیماری پسته در ایران است که یکی از عوامل اصلی آن شبهِقارچ اُاُمیستِ Phytophthora pistaciaeمیباشد. به منظور بررسی واکنش ارقام مختلف پسته ایرانی در برابر P. pistaciae،جدایههایی از این بیمارگر از درختان پسته آلوده به انگومک از مناطق پستهکاری استانهای یزد و کرمان در سالهای 1388 و 1389 جداسازی شدند. این جدایهها با استفاده از خصوصیات ریختشناختی و ژنوم ری...
BACKGROUND Phytophthora is the most important genus of the Oomycete plant pathogens. Nowadays, there are 117 described species in this genus, most of them being primary invaders of plant tissues. The different species are causal agents of diseases in a wide range of crops and plants in natural environments. In order to develop control strategies against Phytophthoraspecies, it is important to k...
Buchnera aphidicola is an obligate symbiotic bacterium that sustains the physiology of aphids by complementing their exclusive phloem sap diet. In this study, we reappraised the transport function of different Buchnera strains, from the aphids Acyrthosiphon pisum, Schizaphis graminum, Baizongia pistaciae and Cinara cedri, using the re-annotation of their transmembrane proteins coupled with an e...
Phytophthora borealis and Phytophthora riparia, identified in recent Phytophthora surveys of forest streams in Oregon, California and Alaska, are described as new species in Phytophthora ITS Clade 6. They are similar in growth form and morphology to P. gonapodyides and are predominantly sterile. They present unique DNA sequences, however, and differ in temperature/growth relations and geographi...
Phytophthora nicotianae is one of the most destructive plant pathogens affecting a variety of plants, causing black shank of tobacco, among several other devastating diseases. Herein, we assembled the mitochondrial genome of P. nicotianae and analyzed its gene content and genome structure, performed comparative mitochondrial genomics analysis, and assessed phylogenetic relationships among oomyc...
گونه های phytophthora drechsleri، p. cryptogea و p. erythroseptica بیمارگرهای گیاهی اُاُمیستی خویشاوندند و از نظر ریخت شناختی به یک دیگر شباهت دارند. برای تمایز این آرایه ها از یک دیگر و از سایر گونه هایی که صفات ریخت شناختی همگرا دارند، شیوه ای بر اساس واکنش زنجیره ای پلیمراز ساده و تودرتو ابداع شد. بدین منظور مجموعه ای از جدایه ها مربوط به میزبان های مختلف، که نماینده ی تنوع موجود در ژن های هست...
Newly discovered Phytophthora species include invasive pathogens that threaten trees and shrubs. We present draft genome assemblies for three isolates of Phytophthora kernoviae and one isolate of the EU2 lineage of Phytophthora ramorum, collected from outbreak sites in Scotland.
Downy mildews and root and foliar rots caused by Phytophthora are among the most destructive plant pathogens and therefore have attracted considerable attention during the past two decades. Although it has been realized that a close phylogenetic relationship exists, so far sharp distinction has been made between the obligate biotrophic downy mildews and the hemibiotrophic Phytophthora. In the s...
