中文简介:
淀粉样欧文菌是引起炭疽病的检疫生物。该病可影响梨树、苹果和枇杷,并影响到各种观赏植物。这种细菌及其引起的疾病已经在几个项目中进行了研究,这些项目的重点是建立诊断系统、西班牙菌株的特性以及该病原体生物学中一些不太知名的方面的研究,以便能够在西班牙的条件下优化疾病的预防控制策略。西班牙分离株变异性的研究已经证实了不同质粒含量的菌株的存在,并且研究集中在一种新质粒的存在与症状发展及其特征的研究上。此外,还发现了梨上致病菌欧文氏菌一新种,并将其质粒含量与梨上致病菌E.amvtovscra(pea29)和梨上致病菌E.pyrifoliae(pep36)的质粒ID进行了比较。
课程简介: Erwinia amylovora is the quarantine organism responsible for the fire blight of rcsacecus plants. The disease can affect pear tree, apple and loquat, and to diverse ornamental plants. This bacterium and the disease it causes have been studied in several projects that focused on setting up diagnosis systems, the characterization of Spanish strains and the study of some not very well-known aspects of the biology of this pathogen, to be able to optimize the strategies for the preventive control of the disease under Spanish conditions.The studies of variability of Spanish isolates have demonstrated the existence of strains with different plasmid content, and the research has focused on the study of the presence of a new plasmid involved in symptoms development and its characterization. Also a new species of erwinia pathogenic on pear, E. Piriflorinigrans, was discovered and its plasmid content compared to that of the plasm ids in E. amvtovcra (pEA29) and E. pyrifoliae (pEP36).
