Phenotypic plasticity is the ability of one genome to develop distinct phenotypes in response to biotic or abiotic environmental stimuli. Notorious examples of phenotypic plasticity in plants include alterations in leaf shape or colour with different light regimes, or changes in flowering time when higher temperatures are perceived. When adaptive, phenotypic plasticity can contribute to increasing plant resilience under changing environments and, consequently, their ecological range. However, the genetics and epigenetics mechanisms underlying phenotypic plasticity remain poorly studied. Understanding its regulation, triggers, or variability at the population level, can provide important tools towards sustainable agriculture and ultimately food security.
This Collection invites original research on plant phenotypic plasticity at the individual or population level, including potential application in agriculture, or its role in evolution.
