The hypoxic niche enclosing the shoot apical meristem is shaped by a combination of morphological features and metabolic activity This study reveals how a functional hypoxic microenvironment enclosing the shoot apical meristem arises through respiratory oxygen consumption and is stabilized by a cuticle-like diffusion barrier and...

High-frequency biparental inheritance of plant mitochondria upon chilling stress and loss of a genome-degrading nuclease - Nature Plants Maternal inheritance of mitochondria breaks down in the cold when a mitochondrial DNA degrading nuclease is defective, resulting in biparental inheritance that can rescue mitochondrial mutations and g...

🌿🧬Our new story is out in @natplants.nature.com! Tobacco plants usually pass down their mitochondria maternally, but we show we can trigger paternal transmission of mitochondria at high levels & restore plant health in the offspring of mothers harboring defective mtDNA www.nature.com/articles/s41...

felicitaciones Enrique!! tremendo trabajo :) keep rocking it! 🎊🎊

This is the kind of thing a rich CEO says at the beginning of a science fiction movie to establish for the audience that he is a sociopath and the villain.

Honest question: why are scientific journals so reluctant to adopt #double-blind peer review?

After all, do we really need to know the authors’ identities to evaluate the scientific merit of a manuscript?

A small polymerase ribozyme that can synthesize itself and its complementary strand The emergence of a chemical system capable of self-replication and evolution is a critical event in the origin of life. RNA polymerase ribozymes can replicate RNA, but their large size and structural ...

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?

Excited to share our latest work in @science.org on a new small polymerase.

The International Conference on Arabidopsis Research, ICAR 2026, 22 - 26 June  | National University of Singapore The International Conference on Arabidopsis Research (ICAR) is the leading annual gathering of the global community of scientists who employ Arabidopsis thaliana as a model system. For nearly four decades, ICAR has showcased the remarkable contributions of Arabidopsis in advancing plant biology, and each year it brings together more than 1,000 scientists from around the world. The 36th ICAR will take place from 22–26 June 2026 at the National University of Singapore, in the heart of one of Asia’s most dynamic cities. Over five days, participants will enjoy keynote lectures, plenary and concurrent sessions, poster presentations, and abundant opportunities for networking and collaboration. Join us in Singapore to share discoveries, exchange ideas, and strengthen connections within our vibrant global community of plant scientists!

👉 A study led by CRAG researchers, published in @theplantjournal.bsky.social, reveals that the molecular toolkit required for carpel formation already existed in the common ancestor of seed plants, long before flowering plants evolved.

Latin America is a richly diverse region of the world that holds extraordinary potential for #singlecell and #spatialgenomics research. Yet LatAm countries remain significantly underrepresented in single-cell publications, with limited access to training and development.

This is today - please come along if interested!

This is a very special paper for me. I had the idea of combining transcription factor binding with chromatin in 2016/8. It took some time, but thanks to Fred and Vikas, we can finally share the story in @plos.org Genetics looking at chromatin states in Arabidopsis and Marchantia. #PlantScience

More than 200,000 Danish citizens have signed a petition to buy California as a response to Trump’s attempt to take Greenland.

They say they will provide Californians with “rule of law, universal health care, fact-based politics, and a lifetime supply of Danish pastries.”
