I think this is a very interesting paper that adds significant understanding in plant water relations.

Out in @science.org this week: A decline in epigenetic silencing of TEs in older plant organs but not in the shoot meristem. TCX5 and TCX6 help regulate DNA methylation in this context.

Aging drives a program of DNA methylation decay in plant organs
Plants display a wide range of life spans and aging rates. Although dynamic changes to DNA methylation are a hallmark of aging in mammals, it is unclear whether similar molecular signatures reflect ra...

Soils drive convergence in the regulation of vascular tension in land plants
Terrestrial vascular plants operate under negative water potential, which results in hydraulic tension in the vascular system. Vascular tension varies with transpiration and soil drying and is regulat...

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
Chromatin state architecture governs transcription factor accessibility across plant genomes
Author summary In eukaryotes, DNA is tightly associated with histone proteins. Histone covalent modifications and histones isoforms, also called histone variants provide most of the complexity of chro...

In hydrozoan #jellyfish, the timing of gamete release is often coordinated by light. Ezio Rosato explores a @plosbiology.org study that elucidates a novel, endogenous clock-based mechanism that governs #egg release in a new species of jellyfish 🧪 Paper: plos.io/4btAwpY Primer: plos.io/49eTOya
Rhythmic ovulation in Clytia species. Top row: In Clytia hemisphaerica, the oocytes develop (blue arrow) becoming competent to respond to the maturation-inducing hormone (MIH), which triggers meiosis. MIH (red triangle) is released by neurosecretory cells in the gonads when they become exposed to light. After completion of meiosis (about 2 hours), the mature eggs are released. Ovulation (green square) lasts about 10 min. Since light is required to start a cycle, whose duration is regulated by the developmental programme, in C. hemisphaerica rhythmic ovulation is analogous to an hourglass. Bottom row: In Clytia sp.IZ-D light is required for synchronous development of the oocytes (blue arrow). However, the final maturation process, which makes them responsive to MIH, is gated by an unknown mechanism that likely operates individually in each oocyte (black-and-blue arrow). Light also drives the accumulation and progressive release of MIH. Meiosis begins when the oocytes reach the right maturation stage and MIH the right concentration. After about 2 hours ovulation begins, lasting about 60 min (green box). Together, the timing mechanisms controlling oocyte development and MIH release constitute an incipient clock. Two light-dark cycles are shown for reference.

New Year. New Office 365. The horrible Co-pilot icon that was present in the bottom right all office documents in December has disappeared from the Office app on my PC in 2026. Things are looking up, perhaps I was not alone in finding it an annoying distraction? Or temporary respite? @microsoft.com

At the end of 2024 I did a chronological round up of all the #plantscience in @science.org that year.
So how did 2025 pan out? This year, I’m grouping papers thematically instead of chronologically so read on to find out what exciting plant science came out over the last 12 months. (1/22)
