It was already known that auxins (surprise!) had a key role controlling the end of flowering, plant menopause. Now we can tell you how and where they act in the inflorescence meristem to control the process.

Local regulation of auxin-related pathways in the shoot apical meristem plays a major role during proliferative arrest
González-Cuadra et al. show that repression of auxin-related pathways locally in the SAM is key in the control of proliferative arrest. FRUITFULL regulates these pathways to promote meristem arrest. B...

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.

It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.

Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

This might be one of the simplest images I captured, but very fascinating nonetheless, as it shows how tight the cytoplasm in a plant cell is. The cytosol and all other organelles are squished between the plasma membrane (magenta) and the central vacuole (its membrane is green)

🌱✂️ How do plant cells decide where to divide?

Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations.
