~12 years after we coined it EPP1 with @oswaldovaldesl.bsky.social one afternoon when we were postdoc with @jeanmichelane.bsky.social!

Congrats @melaniekrich.bsky.social @tatiana-vernie.bsky.social et al. for the hard work!

EPP1 is the fourth member of the Common Symbiosis Pathway 🍄🌱!

So happy to see the latest preprint of the team out! www.biorxiv.org/content/10.1...
The continuation of a long standing project started by @oswaldovaldesl.bsky.social in @jeanmichelane.bsky.social‘s lab. 1/7 🧵

EPP1 is an ancestral component of the plant Common Symbiosis Pathway

The success of plants on land has been enabled by mutualistic intracellular associations with microbes for 450 million years ([Delaux and Schornack 2021][1]). Because of their intracellular nature, th...

How do geminiviruses maximize their limited coding capacity? Our recent preprint uncovers splicing of viral transcripts as one more strategy used by this viral family. We show that RNA splicing is prevalent in the geminivirus TYLCV — and required for infectivity! www.biorxiv.org/content/10.1...

Pervasive splicing in a plant DNA virus

Viruses maximize their limited coding space through strategies that increase transcript and protein diversity. In mammalian viruses, splicing is a well-established mechanism for proteome expansion, ye...

Kubushiro et al. delve deeper into the process of chromatic acclimation in #cyanobacteria & show that rod-shaped photosynthetic supercomplex phycobilisomes in Synechocystis sp.PCC 6803 undergo incomplete photoswitching, likely due to adaptation

#PlantScience

Taken from Figure 4c of https://doi.org/10.1093/pcp/pcaf064: a hypothetical model illustrating changes in the amounts of rod-shaped PBS, hemidiscoidal PBS, PSII, and PSI in PCC 6803. For explanatory purposes, the amounts of PSII and hemidiscoidal PBS are shown as equal between all light conditions: Green (top), Red (middle) and Far Red (bottom).

Chamber of Secrets?

Kinoshita @strnk17desejp.bsky.social & Finkemeier @ifink-lab.bsky.social present an alternative method to precisely measure CO2 assimilation rate & transpiration of #Arabidopsis leaves in whole-plant chambers

Open Access🔗 doi.org/10.1093/pcp/...

Figure 1 from Kinoshita and Finkemeier article showing gas-exchange measurements of petiole-cut Arabidopsis leaves in the whole plant chambers of the LI-6800 system. Panel A shows a schematic diagram of the method i.e. petiole cutting on wet paper and insertion of leaves into a parafilm-sealed dish containing water. Panels B-E are graphs that show C02 assimilation and transpiration rates under different conditions tested
