Outbreaks of acute oak decline (AOD) have been documented in England from 2006. Both species of native oaks (Quercus robur and Quercus petraea) are affected. To complement isolation efforts for identification of putative causative biotic agents and increase our understanding of bacteria associated with oak tissue, five sites in England were chosen for this study. Samples of outer bark, inner ba...
بیماری شانکر سطحی پوست گردوی ایرانی (Juglans regia L.) با عامل Brenneria nigrifluens یکی از بیماریهای مهم و خسارتزا روی تنه و شاخههای اصلی درختان گردو میباشد. تشخیص بهموقع عامل بیماری، نقش مهمی در جلوگیری از خسارتهای جبرانناپذیر آن دارد. در تابستان سال 1392، تعدادی جدایه باکتری از درختان گردو در استان البرز جداسازی گردید. این درختان علایم آشکاری از شانکر پوستی ...
Abstract The phenomenon of hhh Europe has been observed for over 100 years. In this time, many attempts have made to describe considering biotic, abiotic and anthropogenic factors. Recently, an increasing intensity bacterial tree diseases both in around the world. Moreover, climate change is contributing increase range pathogens. aim publication was highlight most important occurring on oaks wo...
Shallow bark canker incited by Brenneria nigrifluens is considered one of the most dangerous diseases which can cause a significant reduction in walnut and timber production. During spring and summer of 2019, walnut gardens were surveyed for symptoms like leaf spot, fruit, and stem canker from four different regions of Golestan province located in Iran. A set of 11 Gram-negative bacteria were ...
Brenneria goodwinii is one of the most frequently isolated Gram-negative bacteria from native oak species, Quercus robur and Q. petraea, affected by acute oak decline (AOD) in the UK. We investigated the population biology of this bacterial species using a multilocus sequence analysis to determine the population structure and evolutionary potential. Seven partial housekeeping genes were used in...
