pathogenic diversity in didymella rabiei in ilam and kermanshah provinces was assessed with the objective of finding out about the existence of pathotypes. one hundred isolates from different farms of chickpea growing regions in these provinces were collected in 2007. isolates were arranged into ten different groups based upon their sampling regions. one isolate was chosen from anyone of the te...

Verticillium wilt caused by soilborne fungus Verticillium dahliae could significantly reduce cotton yield. Here, we cloned a tomato Ve homologous gene, Gbve1, from an island cotton cultivar that is resistant to Verticillium wilt. We found that the Gbve1 gene was induced by V. dahliae and by phytohormones salicylic acid, jasmonic acid, and ethylene, but not by abscisic acid. The induction of Gbv...

Diarrhoeagenic Escherichia coli can be considered as the most important etiologic agents of diarrhoea in the Islamic Republic of Iran, particularly in children. This study determined the frequency of diarrhoeagenic E. coli isolates collected from children with acute diarrhoea (n = 50) and a control group (n = 50) at an Iranian referral paediatric centre during a 1-year period. Using multiplex P...

Enteroaggregative E. coli (EAEC) is an established diarrhoeagenic pathotype. The association with virulence gene content and ability to cause disease has been studied but little is known about the population structure of EAEC and how this pathotype evolved. Analysis by Multi Locus Sequence Typing of 564 EAEC isolates from cases and controls in Bangladesh, Nigeria and the UK spanning the past 29...

Rust diseases cause significant damage in forage and seed crops of perennial ryegrass (Lolium perenne), which is highly heterozygous and heterogeneous and thus presents difficulty in genetic analysis. There has been no definitive demonstration of the existence of pathotypes for stem rust or other rusts of perennial ryegrass, although experiments with crown rust (Puccinia coronata) of this host ...

In the course of biological screening for herbicidal activity in synthetic compounds, various organic iodide complexes had marked defoliating properties when applied to leguminous test plants. Simple iodides such as the salts of alkali metals also caused defoliation. Although this effect has been reported in the patent literature (4, 8), our present investigation was undertaken principally to l...

In the present investigation 16 recombinant inbred lines (RIL’s) developed from intra-specific cross between YH3 and AKDRMS 21-54 through Marker Assisted Pedigree Breeding Method were screened along with their parents checks, namely, BPT 5204, TN1 Improved Samba Mahsuri (ISM) against IxoPt-20 pathotype at ICAR-Indian Institute of Rice Research, Hyderabad during Rabi 2021-22 a new Xanthomonas or...
