Galls are complex structures that develop from plant tissue, providing protection and food for gall-forming organisms, such as insects or mites. However, the molecules used by insects or mites to manipulate plant development have proved elusive. A landmark study has tracked down a gene in a gall-forming aphid that controls whether galls on witch hazel are green or red. The 'green allele' is strongly expressed in aphid salivary glands and represses plant genes used for red color formation. Excitingly, the gene product is part of a large suite of proteins that aphids may use to interact with plant biology.
虫瘿是由植物组织发育而成的复杂结构，为形成虫瘿的生物（如昆虫或螨虫）提供保护和食物。然而，昆虫或螨虫用于操纵植物发育的分子一直难以捉摸。一项具有里程碑意义的研究在一种形成虫瘿的蚜虫中发现了一个基因，该基因控制金缕梅上的虫瘿是绿色还是红色。“绿色等位基因”在蚜虫唾液腺中强烈表达，并抑制用于形成红色的植物基因。令人兴奋的是，该基因产物是蚜虫可能用于与植物生物学相互作用的一大类蛋白质的一部分。
