芽变

Wing bud differentiation initiated at the early 5th nymphal instar, during which the front wing bud cells in the macropterous proliferated much more rapidly than those in the brachypterous. The hinder wing buds of the brachypterous degeneratd at middle 5th instar and finally turned out to be very little wings.

在5龄初始时才发生翅芽发育的分化，之后，短翅型若虫的前翅芽细胞增殖速度明显慢于长翅型，到五龄末期，细胞数量积累明显少于长翅型，短翅型的后翅芽在5龄中期开始退化变短，羽化后变成一个退化的小翅。

Comparing the nucleotide sequences of 16S rRNA gene and ribosomal protein gene, we could find that these two strains have the highest homology of 99.4% and 99.8%, respectively. The nucleotide sequences of 16S rRNA gene for the CWB-YN strain shared higher homology (98.5%,98.9% and 98.0%) with phytoplasma strains in Tomato big bug 16SrI-A group, Western aster yellow (16SrI-B group and Clover phyllody (16SrI-C group). But it is obviously under 97.0% with other phytoplasma groups. The CWB-GZh strain shared higher homology (98.7%,99.1% and 98.3%) with phytoplasma strains in Tomato big bug(16SrI-A group ),Western aster yellow (16SrI-B group) and Clover phyllody (16SrI-C group).

苦楝丛枝病植原体云南株系与其它组16S rRNA基因序列的同源率进行比较，结果与16SrI-A组中的番茄巨芽病植原体(Tomato big bug，BB)、16SrI-B组中的西方翠菊黄化病植原体(Western aster yellow，SAY)和16SrI-C组中的三叶草变病植原体(Clover phyllody，CPh)同源率达最高，分别为98.5%、98.9%和98.0%，而与其它组的植原体16S rRNA基因序列的同源率均低于95%；苦楝丛枝病植原体贵州株系与16Sr I-A组的番茄巨芽病植原体(Tomato big bug，BB)、16Sr I-B组的西方翠菊黄化病植原体(Western aster yellow， SAY)和16SrI-C组中的三叶草变叶病植原体(Clover phyllody，CPh)的同源率达最高，分别为98.7%、99.1%和98.3%。
