Plant glandular trichomes are epidermal secretory structures producing various specialized metabolites. These metabolites are involved in plant adaptation to its environment and many of them have remarkable properties exploited by fragrance, flavor, and pharmaceutical industries. The identification of genes controlling glandular trichome development is of high interest to understand how plants produce specialized metabolites. Our knowledge about this developmental process is still limited, but genes controlling glandular trichome initiation and morphogenesis have recently been identified. In particular, R2R3-MYB and HD-ZIP IV transcription factors appear to play essential roles in glandular trichome initiation in Artemisia annua and tomato. In this review, we focus on the results obtained in these two species and we propose genetic regulation models integrating these data.

植物腺毛是表皮分泌结构，产生各种专门的代谢产物。这些代谢物参与植物对环境的适应，其中许多具有香味，风味和制药工业所利用的显着特性。认识控制毛状体毛状体发育的基因非常重要，以了解植物如何产生专门的代谢产物。我们对这种发育过程的认识仍然有限，但是最近已经发现了控制腺毛开始和形态发生的基因。特别是，R2R3-MYB和HD-ZIP IV转录因子似乎在青蒿的腺毛开始中起着重要作用。和番茄。在这篇综述中，我们关注于在这两个物种中获得的结果，并提出了整合这些数据的遗传调控模型。
