Polymyxa betae اولین بار در سال 1964 به عنوان پارازیت ریشه چغندرقند توسط کسکین (Keskin) تشخیص، نامگذاری وتشریح شد. لکن اهمیت این شبه قارچ بیشتر به خاطر نقش آن در پایداری و انتقال ویروس رگبرگ زرد نکروتیک چغندرقند (, BNYVV(Beet necrotic yellow vein virus عامل بیماری ریشه‌ریشی (ریزومانیا) است. تاکنون آلودگی P. betaeدر گیاهانی نظیر Atriplex patula (اسفناج صحرایی...
BACKGROUND Polyploidy, frequently termed "whole genome duplication", is a major force in the evolution of many eukaryotes. Indeed, most angiosperm species have undergone at least one round of polyploidy in their evolutionary history. Despite enormous progress in our understanding of many aspects of polyploidy, we essentially have no information about the role of chromosome divergence in the est...

Antiquorum sensing investigated pyocyanin swarming motility assay on Pseudomonas aeruginosa PAO1. Results: Phytochemical profile fi...
Four new species of brachypterous Encyrtidae (Hymenoptera: Chalcidoidea) are described. These are: Cheiloneurus mandyanus Hayat, sp. nov., Encyrtus coorgensis Hayat & Zeya, sp. nov., Microterys atturensis Hayat, sp. nov. and Pseudectroma indicum Hayat & Zeya, sp. nov. The following species that exist either in brachypterous forms only or in both brachypterous and macropterous forms are recorded...
Goat manure (GM) is an excellent raw material for anaerobic digestion because of its high total nitrogen content and fermentation stability. Several comparative assays were conducted on the anaerobic co-digestion of GM with three crop residues (CRs), namely, wheat straw (WS), corn stalks (CS) and rice straw (RS), under different mixing ratios. All digesters were implemented simultaneously under...
