Many thanks also to my co-authors and especially Kyra van der Velde who did a lot of work.
Gibberellin transport affects lateral root growth through HY5 in response to far-red light
Gibberellin translocation from shoot to root conveys a plant-plant competition signal that leads to a reduction in lateral root growth.

Please share! I'm looking for a postdoc. The position is to lead one of the following projects: 1) regulation of plant specialized metabolism by cell fate, or 2) foliar embryogenesis in the succulent plant Kalanchoe.

Plant cells are totipotent, meaning individual cells have the potential to develop into a full organism, a property unique to the zygote for animals. However, in most species for most cells, plant cells are not spontaneously totipotent, since they must be treated with specific hormone combinations to unlock their totipotency. Species within the Kalanchoe genus is unique as they spontaneously develop foliar embryos that are fully realized plantlets with shoot and root from notches along the edges of leaves. We speculate that the progenitor cells that give rise to these foliar embryos are totipotent, and we are using single cell techniques to identify & characterize them. In addition to being a fundamental process for plant biology, we foresee unlocking totipotency has many biotechnological applications, such as faciliating genetic transformation and the development of synthetic organs of biomanufacturing.

New paper: Gibberellins are long-distance regulators of shoot-to-root signalling of the light environment
Our latest paper ( published online in Plant Cell, shows that Gibberellins are involved in long-distance signalling of phytochrome-sensed light signals all the way in to the roots that are not light-exposed but still respond to light quality changes. We think that not only the precursor GA12, but also bioactive GA4 is shoot-to-root mobile. The work was led by former postdoc…

Scientists, academics, researchers: We’re excited to share that @altmetric.com is now tracking mentions of your research on Bluesky! 🧪
There are already many articles for which there is more attention on Bluesky than on other comparable micro-blogging sites, meaning the academic community and the general public have clearly adopted Bluesky as one of its core places to disseminate and discuss new research.

A Place of Joy.
