Abstract

The utility of 36 presumptive determinative tests for 32 pathovars of Pseudomonas syringae was investigated. A total of 395 strains was examined. Most strains of 12 of these pathovars (Ps. syringae pv. cannabina, Ps. syr. delphinii, Ps. syr. glycinea, Ps. syr. helianthi, Ps. syr. lachrymans, Ps. syr. mori, Ps. syr. morsprunorum, Ps. syr. phaseolicola, Ps. syr. 'porri', Ps. syr. papulans, Ps. syr. savastanoi and Ps. syr. tabaci) formed clusters when test data were compared by centroid analysis. Pseudomonas syr. syringae, Ps. syr. aptata, Ps. syr. atrofaciens, Ps. syr. dysoxyli and Ps. syr. japonica formed a single cluster, indicating their possible synonymy. Strains of Ps. syr. antirrhini and Ps. syr. tomato were indistinguishable, as were those of Ps. syr. garcae and Ps. syr. oryzae. Strains of Ps. syr. berberidis, Ps. syr. coronafaciens, Ps. syr. eriobotryae, Ps. syr. maculicola, Ps. syr. passiflorae, Ps. syr. pisi and Ps. syr. striafaciens and Ps. syr. tagetis did not form distinguishable clusters. The tests which reliably differentiated pathovars are recorded in a determinative scheme.

丁香假单胞菌病原菌测定方法的评价。

对32种丁香假单胞菌病原菌的36种推定检测方法的实用性进行了研究。共检测了395株菌株。当通过质心分析对测试数据进行比较时，这些致病性变体中的12个（紫丁香、飞燕草、甘氨酸、向日葵、泪腺、莫里、morsprunorum、phaseolicola、porri、papulans、savastanoi和tabaci）的大多数菌株形成聚类。丁香假单胞菌（Pseudomonas syr.syringae）、适足假单胞菌、萎缩假单胞菌，脱氧假单胞菌和日本假单胞菌形成一个单一的集群，表明它们可能是同义词。抗莱茵假单胞菌和番茄假单胞菌的菌株是不可区分的，加氏假单胞菌与米曲霉的菌株也是如此。berberidis、coronafaciens、eriobotryae、maculicola、passiflorae、pisi和striaffaciens和tagetis菌株没有形成可区分的簇。可靠区分病理变化的测试记录在一个决定性的方案中。
