Gall is a plant structure formed by abnormal growth within plant tissu

es. They usually secrete enzymes or plant hormones that stimulate hypertrophy or

 hyperplasy in their host plant, and the resulting structures are quite distinct

ive and highly speciesspecific. Their development is largely controlled by ins

e

ct genes. The molecular basis of gall induction remains unknown in many insect g

alls. This paper summarized biology, including morphologic f

eatures, forming mechanism, etc.

虫瘿是造瘿昆虫诱导植物组织不正常生长产生的,它们通过释放某些酶或者植物激素

刺激寄主植物细胞增大或增殖产生了特异形态的虫瘿，而这种特异形态就是造瘿昆虫遗传基

因的体外表达。但虫瘿产生的分子机制不是十分清楚，文章主要对目前植物虫瘿的形态特征

、形成机制等方面进行综述。
