Wounding articles from across Nature Portfolio

Products of the mevalonate pathway support plant development. Here the authors show that the extracellular ATP receptor P2K1 phosphorylates mevalonate kinase and this affects the mevalonate pathway.

Matsuoka et al. study the mechanism by which transcription factors ANAC071 and ANAC096 promotes regeneration of wounded tissue in Arabidopsis by mutagenesis and morphological characterization. They find that these factors are essential for wound-induced cambium formation from dedifferentiated cells before the initiation of cell division.

Hyo-Jun Lee et al. show that submergence in Arabidopsis deactivates wound-induced defence against herbivore attack by suppressing the expression of jasmonic acid biosynthesis genes and increasing expression of ethylene-responsive genes. These results shed light on how flooding may impact plant defence systems.
