Tissue-specific interference reveals complex roles for auxin signalling in procambial cells during graft healing in Arabidopsis
Plant Science Research WeeklyFor hundreds of years, we have propagated plants clonally by grafting, i.e. the union of a scion and a rootstock to form a new plant. To be successful, a graft junction must heal: tissues must attach, and vascular bundles reconnect, in a process known to involve auxin. Here, Serivichyasw at et al. investigate…
Sealing the deal to graft healing: PAT1 as a novel regulator of graft formation
Plant Science Research WeeklyGrafting is a way to combine the desirable properties of two plants by joining the scions and rootstocks from different plants. While frequently practiced, little is known about how grafting within and between coniferous species works. Most pertinently, grafting success relies on how efficiently connected…
