Rapid Detection of Xanthomonas citri pv. fuscans and Xanthomonas phaseoli pv. phaseoli in Common Bean by Loop-Mediated Isothermal Amplification

Genetic Diversity and Pathogenic Variation of Common Blight Bacteria (Xanthomonas campestris pv. phaseoli and X. campestris pv. phaseoli var. fuscans) Suggests Pathogen Coevolution with the Common Bean.

ABSTRACT Common bacterial blight (CBB), caused by Xanthomonas campestris pv. phaseoli and X. campestris pv. phaseoli var. fuscans, is one of the most important diseases of common bean (Phaseolus vulgaris) in East Africa and other bean-growing regions. Xanthomonad-like bacteria associated with CBB in Malawi and Tanzania, East Africa, and in Wisconsin, U.S., were characterized based on brown pigm...

Differential Pathogenicity of Xanthomonas campestris pv. phaseoli and X. fuscans subsp. fuscans Strains on Bean Genotypes with Common Blight Resistance

Genome sequencing reveals a new lineage associated with lablab bean and genetic exchange between Xanthomonas axonopodis pv. phaseoli and Xanthomonas fuscans subsp. fuscans

Common bacterial blight is a devastating seed-borne disease of common beans that also occurs on other legume species including lablab and Lima beans. We sequenced and analyzed the genomes of 26 strains of Xanthomonas axonopodis pv. phaseoli and X. fuscans subsp. fuscans, the causative agents of this disease, collected over four decades and six continents. This revealed considerable genetic vari...

Fluctuation in some enzymes related to antioxidant defense system in common bean against Xanthomonas axonopodis pv. Phaseoli

Antioxidant enzymes play an important role in plant defense against pathogenic agents. Following the identification of the pathogen, plants produce active oxygen species (ROS) as one of their first defense responses. To maintain the balance of ROS levels and prevent their harmful effects, plants produce antioxidant peroxidase (POX), catalase (CAT), ascorbate peroxidase (APX) and superoxide dism...

مقایسه روش‌های مختلف ردیابی باکتری Xanthomonas axonopodis pv. phaseoli در بذر لوبیا* Comparison of different methods for detection of Xanthomonas axonopodis pv.phaseoli in bean seeds

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 ...
