Analysis and review of trichomes in plants
Abstract
Abstract Background Trichomes play a key role in the development of plants and exist in a wide variety of species. Results In this paper, it was reviewed that the structure and morphology characteristics of trichomes, alongside the biological functions and classical regulatory mechanisms of trichome development in plants. The environment factors, hormones, transcription factor, non-coding RNA, etc., play important roles in regulating the initialization, branching, growth, and development of trichomes. In addition, it was further investigated the atypical regulation mechanism in a non-model plant, found that regulating the growth and development of tea ( Camellia sinensis ) trichome is mainly affected by hormones and the novel regulation factors. Conclusions This review further displayed the complex and differential regulatory networks in trichome initiation and development, provided a reference for basic and applied research on trichomes in plants.
