Gibberellin translocation from shoot to root conveys a plant-plant competition signal that leads to a reduction in lateral root growth.

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.

Plants use several photoreceptors to perceive light including the cryptochromes (CRYs), which are implicated in blue-light reception and coordinate developmental processes including…

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…
