Logo for the 49th New Phytologist Symposium: Biological timing in photosynthetic organisms. An illustration of Earth with the moon on the left and sun on the right. The planet is divided in two between day and night. Plants have been drawn over the landmasses. On the night side, trees in autumn colours grow in North America and a bat pollinating a flower is present in the tropical rainforest of South America. Snowdrops grow across Europe. On the day side, boreal forest extends across northern Asia, grassland occupies southern Asia, the steppe and Australia. Mimosoid plants and large trees are present in Africa. A bee pollinates a magnolia in South-East Asia, and a cherry blossom tree blooms in Japan.
49th New Phytologist Symposium

Biological timing in photosynthetic organisms

The symposium will focus on the importance of biological timing across all scales of plant biology, from molecules to organisms, communities, and ecosystems

Why should every plant biologist care about biological timing? Virtually all aspects of plant life are shaped by temporal regulation across many scales, including the cycles of day and night, and the seasons of the year. This Symposium brings together diverse topics in biological timing including environmental signalling, evolution, field biology, modelling, epigenomics, organismal interactions, and how circadian clocks and seasonal timing can be leveraged for crop breeding.

This Symposium will emphasise underlying principles and concepts that characterise these processes, whilst considering a wide range of species and approaches. There are numerous unanswered questions, such as how daily and seasonal timing shapes plant function in natural conditions, ecological processes, microbiome interactions, and the evolution of photoperiodism and circadian clocks. By combining laboratory and field research with molecular and ecological approaches, this multidisciplinary Symposium will cut across all sections of the New Phytologist readership, fostering creative new synergies.
