Hi - we are looking for a PhD student to finish the thapsigargin biosynthesis. If you are up for some great work, then apply.
Ever wondered how the #cuticle, a hallmark of land plants, was established?
In our latest study, we show that the CUTIN SYNTHASE enzyme family was a key driver of this evolutionary innovation. #plantscience

We wanted to know what plants in the wild really care about. So we asked them 🎤.
Here is what we learned: “Biotic-response networks are an important organizer of the transcriptome in wild Arabidopsis thaliana populations”

Fig. 4 (shortened, full legend in paper): Visualization of root and shoot morphological adaptation to maintain developmental rate based on the resource budget. The drawing shows morphological changes for decreasing internal resource levels from left to right. In the top section, two leaves demonstrate the increase in SLA in response to reduced resources to maintain the same leaf area, but spending less resources. In the bottom section, we drew three roots, the leftmost representing root growth under high resource availability, and the middle and rightmost representing alternative adaptations to reduced resource availability. In the middle root, the formation of aerenchyma results in a reduction of resource costs while maintaining root diameter and depth. In the right root, instead, resource expenditure is reduced by reducing root diameter, while maintaining rooting depth.

This review describes how plants safeguard plant-level homeostasis through coordinating resource uptake, developmental rate, and morphological efficiency in response to environmental and internal signal – Earle et al.

Fluorescence microscopy image of a spherical cluster of chloroplasts, showing magenta-stained interiors surrounded by bright green outlines against a black background.
Moss (Physcomitrium patens) protoplasts (wallless cells) transformed with chloroplast envelope protein tagged with mGFP (green). The chlorophyll autofluorescence is in magenta.
The protrusions of the chloroplast envelope are called stromules.

Chloroplast ABC peptide transporters TAP1, NAP8, and ATH12 are essential for heat-induced peptide export and play a key role in thermotolerance in Arabidopsis thaliana. www.biorxiv.org/content/10.64898/2026.03...
The cover of Vol 77 | Issue 5 | 2026 of the Journal of Experimental Botany, Special Issue: Energy Management: Molecular Mechanisms and Signaling. Yellow coloured banners border the top and bottom of the page and in the centre the image depicts a whiteboard illustration of the original concept behind the workshop ‘Plant Energy Management: Molecular Mechanisms and Signalling,’ held at UPSC, Sweden, in August 2024. The aim was to expand upon the original TOR meeting by focusing on the inputs and outputs of the core energy management machinery in a species-agnostic manner.

Plastids, photosynthetic organelles in plants and algae, originated from cyanobacterial endosymbiosis. Here, Shrestha et al. use metagenomics to expand plastid diversity and provide evidence for two independent origins of secondary red-algal plastids.

Dear Plant ECRs, don't miss this wonderful opportunity!
La médaille de l’innovation 2025 du CNRS est décernée à Alda Mari, Aziz Moqrich, Pascale Senellart et Alain Wagner. Ils illustrent la variété des recherches du CNRS et le rôle primordial que joue la recherche fondamentale dans le développement de technologies de rupture. 👏
Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.

Images of plants mock treated (left) or treated with molecule X57 (right). X57 treatment causes yellowing of the true leaves (upper row), and a reduction in photosynthetic capacity (lower row).
