Michaels, T. E., Smith, T. H., Larsen, J., Beattie, A. D. and Pauls, K. P. 2006. OAC Rex common bean. Can. J. Plant Sci. 86: 733–736. OAC Rex is an upright indeterminate bush white bean (Phaseolus vulgaris L.) cultivar intended for use in areas with greater than 2800 crop heat units. It has good yield potential in either wide or narrow row production. It is resistant to races 1 and 15 of bean c...
The transcript levels of six defense genes including pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), pathogenesis-related gene 5 (PR-5), lipoxygenase (LOX), phenylalanine ammonia-lyase (PAL) and catalase (CAT) were investigated in tomato plants inoculated with Xanthomonas axonopodis pv. phaseoli as a non-host pathogen and X. euvesicatoria as a host pathogen. Activation o...
Yeast associates with many plant parts including the phyllosphere, where it is subject to harsh environmental conditions. Few studies have reported on biological control of foliar pathogens by yeast. Here, we newly isolated leaf-colonizing yeasts from leaves of field-grown pepper plants in a major pepper production area of South Korea. The yeast was isolated using semi-selective medium suppleme...
The Gram-negative bacterium Xanthomonas axonopodis pv. citri, the causal agent of citrus canker, is a major threat to the citrus industry worldwide. Although this is a leaf spot pathogen, it bears genes highly related to degradation of plant cell walls, which are typically found in plant pathogens that cause symptoms of tissue maceration. Little is known on Xac capacity to cause disease and hyd...
PAMDB, a multilocus sequence typing and analysis database and website for plant-associated microbes.
Although there are adequate DNA sequence differences among plant-associated and plant-pathogenic bacteria to facilitate molecular approaches for their identification, identification at a taxonomic level that is predictive of their phenotype is a challenge. The problem is the absence of a taxonomy that describes genetic variation at a biologically relevant resolution and of a database containing...
Xanthomonas vasicola pathovar vasculorum (Xvv) is the bacterial agent causing gumming disease in sugarcane. Here, we compare complete genome sequences for five isolates of Xvv originating from sugarcane and one from maize. This identified two distinct types of lipopolysaccharide synthesis gene clusters among Xvv isolates: one is similar to that of Xanthomonas axonopodis pathovar citri (Xac) and...
از باغات مرکبات مناطق مختلف جنوب ایران دو باغ آزمایشی در دو منطقه کهنوج و جیرفت انتخاب و هر باغ به دو بخش تقسیم گردید. در یک بخش از باغ عملیات هرس زمستانه انجام شد و بخش دیگر به صورت دست نخورده باقی ماند. در هر دو بخش باغ غلظت های 3، 1.5 و 1 در هزار اکسی کلرور مس و غلظت های 1، 0.75 و 0.5 درصد از محلول بوردو در سه زمان زمستان اوایل فصل رشد و پس از گلدهی درقالب طرح بلوک های کامل تصادفی با چهار تک...
Bacterial spot disease on tomato is a major problem in tropical, subtropical, and temperate climates. Variation within this organism has been well documented. Two distinct groups, i.e., A and B, were identified in the early 1990s based on phenotypic and genotypic tests. These two groups were determined to be distributed widely throughout the world. The two groups were placed in Xanthomonas axon...
در سالهای اخیر بیماری سوختگی معمولی لوبیا خسارات زیادی را به مزارع لوبیا در ایران وارد کرده است. اصلی‌ترین منبع گسترش این بیماری کاشت بذور لوبیای آلوده به axonopodis pv. phaseoli Xanthomonas می‌باشد و لذا اطمینان از عدم آلودگی بذور به عامل بیمارگر در کنترل بیماری نقش اساسی دارد. در این بررسی کارایی روش‌های الایزای غیر مستقیم، آزمون PCR مستقیم، Ic-PCR و Bio-PCRبرای ...
