Integrating Genetic Pathways for Photoperiod and Temperature Response in Plants

This document focuses on the genetic mechanisms underlying plant responses to photoperiod and temperature, specifically through circadian clock pathways, signaling components like CRY2, GI, and FPA, and their roles in vernalization and gibberellin pathways. It discusses modeling approaches based on literature data from notable studies (Suarez-Lopez et al., Samach et al., Blazquez et al.) and presents results from experiments examining long-day and short-day conditions. The findings enhance our understanding of how genes interact to regulate flowering time and seasonal growth.
