Temperature regulation of cell cycle and growth dynamics in Arabidopsis

Abstract

The plant cell cycle is a highly coordinated and regulated process that integrates endogenous and environmental signals to control cell division, meristem maintenance, and cell fate specification for growth and development. Temperature is a critical environmental signal that regulates the cell cycle to manifest developmental plasticity in Arabidopsis roots and shoots. Arabidopsis plants exhibit either adaptive growth responses or arrested growth, depending on the temperature regime. The temperature-mediated growth dynamics in Arabidopsis involve altered cell-cycle regulation. While plant developmental and physiological responses to temperature have been extensively studied, the integration of temperature signalling cues with cell-cycle dynamics to regulate growth adaptation remains poorly understood. The present review not only compiles existing information on temperature-mediated regulation of cell-cycle dynamics but also provides a perspective on multidisciplinary approaches to investigate cell-cycle dynamics at spatiotemporal resolution in Arabidopsis adaptive growth responses.
