简介:2013年3月20日,研究论文《VitellogeninReceptorMutationLeadstotheOogenesisMutantPhenotype‘scantyvitellin’oftheSilkworm,Bombyxmori》在《Journalofbiologicalchemistry》杂志在线发表http://www.ncbi.nlm.nih.gov/pubmed/23515308。文章详细地阐释卵黄原蛋白受体在卵的形成及胚胎发育中扮演的重要角色:如果受体缺乏或异常会导致卵不能正常形成,卵中营养物质严重缺乏,最终导致后代不能正常生长而致死。这一结果为鳞翅目害虫的卵黄原蛋白受体的研究奠定了基础,为害虫防治提供了新的靶标基因。
