Phenotypic plasticity of cambial secondary growth in Brassicaceae in response to temperature and day length (A03)

A3（Shi）研究了形成层干细胞活性对温度和日照长度的可塑性。地球上大多数植物生物量是由形成层驱动的次生加厚生长的直接产物。形成层干细胞对环境的反应是有据可查的，是树木明显年轮形成的基础。本计画将探讨在A.拟南芥下胚轴和萝卜根作为一个强大的模型，以确定在形成层可塑性的变化，利用单细胞转录组学补充的数量遗传学的遗传和分子基础。

A3 (Shi) investigates the plasticity of cambium stem-cell activity to temperature and day length. Most plant biomass on earth is the immediate product of secondary thickening growth driven by the cambium. The environmental responsiveness of cambium stem cells is well documented and underlies the formation of pronounced annual rings in trees. This project will exploit the variation in plasticity of secondary thickening growth in A. thaliana hypocotyls and radish roots as a powerful model to identify the genetic and molecular basis of variation in cambium plasticity using quantitative genetics supplemented by single-cell transcriptomics.
