Summary
Flowering is a critical developmental transition in plants, determining reproductive success, crop yield, and adaptation to changing environments. This Special Issue aims to bring together cutting-edge research that bridges molecular regulation and ecological adaptation in plant flowering.
Recent advances in molecular biology have uncovered key regulatory pathways governing flowering time, including photoperiod, vernalization, and hormonal signaling. However, how these molecular mechanisms translate into ecological and evolutionary responses remains an active area of investigation. Phenological traits, including the timing of flowering, provide valuable indicators of how plants integrate environmental cues and adjust their developmental responses under changing conditions. Understanding this connection is essential for predicting how plant populations and agricultural systems will respond to climate change.
We invite contributions that address flowering regulation from the molecular to the ecosystem level. Suggested themes include, but are not limited to:
-Molecular mechanisms of flowering time regulation (photoperiod, vernalization, temperature)
-Hormonal and epigenetic control of flowering
-Flowering phenology and climate change
-Ecological and evolutionary implications of flowering variation
-Flowering regulation in crop species and wild relatives
-Adaptation of flowering time to local environments
-Integrative approaches combining molecular, physiological, and ecological perspectives
This Special Issue welcomes original research, reviews, and short communications that advance our understanding of flowering as a key trait linking plant development, ecology, and adaptation.
