🧪🌾REVIEW - Is the circadian clock merely light driven?

@luiscervela.bsky.social, Marta Francisco @csic.es & Åsa Strand illustrate that the circadian system also acts as a central integrator of energy status and environmental cues.

Plants don’t just use light to set their circadian clock—metabolites like sugars, ROS & organic acids from chloroplasts & mitochondria feed back on clock genes via retrograde signaling, forming a dynamic light–clock–metabolism feedback loop. doi.org/10.3390/plan...

Very proud to have contributed to this great study!

Retrograde signals control dynamic changes to the chromatin state at photosynthesis-associated loci - Nature Communications Quevedo et al., demonstrate that the epigenome is closely connected to organellar activities through retrograde signals, and that such signals drive specific changes to chromatin availability that per...

Amazing work by former colleagues and friends. Many congratulations Martí Quevedo, Ivona Kubalová, Alexis Brun, @luiscervela.bsky.social, Elerna Monte and Åsa Strand. 🌱🎉👏👏

CDK8 of the mediator kinase module connects leaf development to the establishment of correct stomata patterning by regulating the levels of the transcription factor SPEECHLESS (SPCH) The components of the mediator kinase module are highly conserved across eukaryotic lines and cyclin-dependent kinase 8 (CDK8) is essential for correct cell proliferation and development. We show her...

Ever wondered how plants breathe and manage water loss? 🌿 This depends on tiny pores called stomata. A new study reveals how a key regulator, CDK8, ensures these pores form in the right places, connecting leaf growth to function.

Curious to learn more?

I always liked this quote in defense of basic science:

"To feed applied science by starving basic science is like economizing on the foundations of a building so that it may be built higher. It is only a matter of time before the whole edifice crumbles".

— George Porter

Plants rely on an internal clock to balance their metabolism between day and night. The TOC1 protein plays a key role, regulating energy and sugar production. When TOC1 is disrupted, plants struggle to maintain this balance, impacting growth and survival. 🌱⏳

An interplay between bZIP16, bZIP68, and GBF1 regulates nuclear photosynthetic genes during photomorphogenesis in Arabidopsis The development of a seedling into a photosynthetically active plant is a crucial process. Despite its importance, we do not fully understand the regulatory mechanisms behind the establishment of ...

Plants 'wake up' to light using proteins bZIP16, bZIP68 & GBF1 to kickstart chloroplast development for photosynthesis. These light-sensitive switches fine-tune growth, ensuring seedlings thrive as they transition from dark to light. 🌱☀️

Plant adapt their growth to their environment. A leaf, for example, growing under higher CO2 concentrations has fewer stomata. Swedish researchers show in Plant, Cell & Environment how plants are regulating this.
