Many of you may have heard the terrible news of Dr. Meng Chen's sudden death. I just found this tribute from UC Riverside cnas.ucr.edu/news/2026/09... and a beautiful review article he contributed to @plantphys.bsky.social earlier this year, "25 years of photobodies" doi.org/10.1093/plph... 💔

The first preprint of my lab has just come out doi.org/10.64898/202... This paper came out at the same day on the sudden passing of Prof. Meng Chen. Without his work, this paper would not have existed. He was an extremely supportive member of the plant photobiology community..

So proud to share our latest publication @CellCellPress! Yue Rui reveals that the same enzyme that makes the wall, cellulose synthase complex (CESA), also tethers the plasma membrane to the wall during water-deficit stress, providing resilience. sciencedirect.com/science/articl…

Further evidence that sugar in the plates changes the plant biology you study. Best to avoid putting sugar in the agar, unless you want to study what sugar in the agar does to plants. This paper uses sugar in the agar to study what sugar does. www.nature.com/articles/s41... #plantresearch

Biomolecular condensates are critical for organizing cellular contents, but most studies focus on phase separation driven by salt, pH, or temperature. But what if intracellular movement also matters? Here, we explore motility-induced condensation in the cell. www.science.org/doi/10.1126/...

Active transport enables protein condensation in cells
The force generated by active transport modulates protein condensation.
