New Article: "Occupancy-based mechanism is the chief mode of ROS1 function in preventing DNA hypermethylation" rdcu.be/fb7P0 ROS1 mediates DNA demethylation via a passive mechanism; ROS1 occupancy marks & regulates accessible chromatin, highlighting its diverse roles.

We have been cooking up this story for a while and we are excited to finally be able to share! Read on if you're interested in whole plant regeneration WITHOUT the application of hormones!

New #preprint 😍‼️ led by 2 incredible postdocs Ni Zhan & @ranjithbio: transforming #UFMylation from a local ribosome rescue pathway to systems level regulator of mRNA splicing biorxiv.org/content/10.648… A short 🧵

Our new experimental evolution study across 30+ locations using the plant Arabidopsis thaliana —— we direct "see" adaptation and extinction to different climates at the genetic as it happens! Read it in Science dx.doi.org/10.1126/scienc… @UCBerkeley @hhmi_science

Histone deacetylases and cell cycle regulators orchestrate cell identity transitions during Arabidopsis root regeneration #research #MolecularPlant cell.com/molecular-plan…

Wild rice is a perennial, creeping plant. The secret to its perennial growth habit lies in a developmental reversal directed by small RNAs. This image illustrates how combining perennial genes with prostrate growth genes allows cultivated rice to mimic wild rice. These findings pave the way for the future development of sustainable perennial rice cultivars. Learn more this week in Science: scim.ag/4sYKfug

Thank you Ito En for reaching out, and here we are. It‘s really good. Oishii ! I love JAPAN and GREEN TEA. #greentea #ITOEN #OiOcha @oiochakun @itoen1966_jp

🌿 New paper from the lab out in @NaturePlants! We built a single-cell atlas of Arabidopsis leaf development to ask: how does drought reshape leaf gene expression at the cellular level? doi.org/10.1038/s41477… 🧵
