Fig. 1 Lignin accumulation in cell walls differentially covers the surface of polysaccharides and fills in the cell wall void spaces to dynamically adjust cell wall hygroscopic and mechanical properties.

In all land plants, small secreted peptides belonging to the CLE family move from cell to cell and activate their cognate receptors to control a plethora of developmental processes - Cornelis & Hazak

#PlantScience 🧪 @hazaklab.bsky.social
Box 1. (shortened, full legend in paper): Key developments in understanding the role of CLE signalling in plant development. This scheme represents a summary on the selected latest advances in CLE signalling. (A) In a series of publications, Yuki Hirakawa and his team (Takahashi et al., 2021, 2023) characterized the CLE pathway in the liverwort Marchantia polymorpha that positively controls cell divisions via repressing the transcription factor JINGASA. (B) In Arabidopsis, CLV3/CLV1 signalling in the shoot was found to be buffering auxin-dependent development under different thermal conditions (John et al., 2023). (C) Research from several teams showed that the BAM3/CLE pathway is crucial for root protophloem development (Hu et al., 2018, 2022; Qian et al., 2022; Carbonnel et al., 2023). Moreover, the study by Carbonnel et al. (2023) identified an uncharacterized Arabidopsis CLE33 gene that acted in concert with CLE45 via BAM3 in root protophloem development.

Great to see the data of the drought-net coming together: drought intensity and duration matter!
science.org Science Magazine @science.org · Oct 21
Although many ecosystems can weather several years of moderate drought, consecutive years of extreme dryness push them past a tipping point, resulting in dramatic declines in plant growth, researchers report in Science. https://scim.ag/4ogN9I8
Drought intensity and duration interact to magnify losses in primary productivity
As droughts become longer and more intense, impacts on terrestrial primary productivity are expected to increase progressively. Yet, some ecosystems appear to acclimate to multiyear drought, with cons...
