自1967年发现类菌原体以来,至今已有一百余种植物病害,特别是植物黄化型病害,被认为是类菌原体致病。类菌原体大小不一,一般为80～800毫微米,形态多样,大都为圆形或椭圆状,具有约10毫微米厚的单位膜;可以通过人工嫁接和菟丝子传播,但主要依靠带毒媒介昆虫传播;能被四环素族抗菌素抑制。对于植物类菌原体的分离培养,曾进行过许多尝试,但一直未获成功,因此未能按照柯赫氏定则最终肯定病原性。玉米矮化病(Corn stunt disease)和柑桔顽固病(Citr
Since the discovery of mycoplasmas in 1967, so far there have been more than 100 kinds of plant diseases, especially plant yellow disease, is considered to be pathogenic Mycoplasma. Mycoplasmas vary in size, generally 80 to 800 nm in shape and shape, mostly round or oval, with a unit membrane of about 10 nm thick; can be spread by artificial grafting and dodder, but rely mainly on Media insects spread; can be tetracycline antibiotic. There have been many attempts to isolate and culture phytoplasma, but they have been unsuccessful. Therefore, they failed to finally confirm the pathogenicity according to the Koch’s rule.
