Zusammenfassung:	Copyright © 2021 Elsevier B.V. All rights reserved. Plants are sessile and lack behavioural responses to avoid extreme environmental changes linked to annual seasons. For survival, they have evolved elaborate sensory systems coordinating their architecture and physiology with fluctuating diurnal and seasonal temperatures. PHYTOCHROME-INTERACTING FACTOR 4 (PIF4) was initially identified as a key component of the Arabidopsis thaliana phytochrome signalling pathway. It was then identified as playing a central role in promoting plant hypocotyl growth via the activation of auxin synthesis and signalling-related genes. Recent studies expanded its known regulatory functions to thermomorphogenesis and defined PIF4 as a central molecular hub for the integration of environmental light and temperature cues. The present review comprehensively summarizes recent progress in our understanding of PIF4 function in Arabidopsis thaliana, including PIF4-mediated photomorphogenesis and thermomorphogenesis, and the contribution of PIF4 to plant growth via the integration of environmental light and temperature cues. Remaining questions and possible directions for future research on PIF4 are also discussed
