Regulation of Shoot Apical Meristem and Axillary Meristem Development in Plants

Int J Mol Sci. 2020 Apr 21;21(8):2917. doi: 10.3390/ijms21082917.


Plants retain the ability to produce new organs throughout their life cycles. Continuous aboveground organogenesis is achieved by meristems, which are mainly organized, established, and maintained in the shoot apex and leaf axils. This paper will focus on reviewing the recent progress in understanding the regulation of shoot apical meristem and axillary meristem development. We discuss the genetics of plant meristems, the role of plant hormones and environmental factors in meristem development, and the impact of epigenetic factors on meristem organization and function.

Keywords: axillary meristem; epigenetics; plant hormones; shoot apical meristem; transcription.
