How do cells communicate when it’s hot? (FAULKNER_J26DTP) | Doctoral Training Partnership
Plant cells are connected to their neighbours via ‘tubes’ called plasmodesmata, creating an interconnected cytoplasm that joins cells within and between tissues and organs.

Here are some “leaf” or phyllid cells from moss Physcomitrium patens gametophore. Cells are expressing a green fluorescence marker that labels the vacuolar membrane. Chloroplasts' autofluorescence is in magenta.
Can you spot dividing chloroplasts?

KATANIN promotes cell elongation and division to generate proper cell numbers in maize organs
Microtubule severing is essential for proper eukaryotic cell elongation and division. Here we show that the microtubule severing protein, KATANIN, is encoded by two genes in Zea mays (maize) called Di...

ER exit sites are dynamic ER subdomains that integrate signals, reshape membranes and steer secretion. Twelve groups in the field came together to map their diversity, regulation, unanswered questions and future directions.

Towards a unified framework for the function of endoplasmic reticulum exit sites - Nature Reviews Molecular Cell Biology
Endoplasmic reticulum exit sites (ERES) are specialized ER subdomains that regulate the export of secreted cargo. This Roadmap explores how ERES integrate biochemical and mechanical signals to coordinate trafficking and proposes a multidisciplinary strategy to investigate their function, including in disease.

New OA Article: "Stem cell regulators drive a G1 duration gradient during plant root development" rdcu.be/eHcg2
The G1 phase is very long close to the stem cell niche. This relies on the interplay of PLETHORA with the RETINOBLASTOMA-RELATED pathway.
