  • 简介:提炼伴随转变从的变化对在蝗虫的独居的阶段状态群居是那么激烈的很长时间,这些阶段被看作不同种类。是鲍里斯·乌瓦罗夫介绍了polyphenism的概念。研究的十年表明阶段转变在morphometry,表皮的颜色,行为和生理学的几个方面暗示变化。在最近的十年,特别地,相当很多分子的研究被承担了揭开阶段相关的差别。他们导致了新奇卓见进corazonin的角色,neuroparsins,一些朊酶禁止者,phenylacetonitrile等等。蝗虫的EST数据库的来临(例如坑等,2004)是在生理、行为的蝗虫研究的很令人鼓舞的新奇开发。然而,最吸引人的问题的答案,也就是是否有阶段转变的初发的分子的inducer,在不久的将来可能不在活动范围以内。
