英文摘要	Plants that produce great fruit may not always have great roots. Grafting of a productive scion onto a resilient rootstock has provided agriculturalists with solutions to this and other challenges. Notaguchi et al. have now studied why some plant grafts work better than others (see the Perspective by McCann). The tobacco relative Nicotiana benthamiana ( Nb ) turns out to be the superhero of grafting, able to form grafts with plants from a wide range of evolutionary families. A bit of Nb , set as a middleman between a tomato scion and an Arabidopsis rootstock, negotiated a successful junction between these two otherwise nonconversant plant species. The expression of β-1,4-glucanases secreted into the extracellular region turns out to be key in facilitating cell wall reconstruction. Science , this issue p. [698][1]; see also p. [618][2] Plant grafting is conducted for fruit and vegetable propagation, whereby a piece of living tissue is attached to another through cell-cell adhesion. However, graft compatibility limits combinations to closely related species, and the mechanism is poorly understood. We found that Nicotiana is capable of graft adhesion with a diverse range of angiosperms. Comparative transcriptomic analyses on graft combinations indicated that a subclade of β-1,4-glucanases secreted into the extracellular region facilitates cell wall reconstruction near the graft interface. Grafting was promoted by overexpression of the β-1,4-glucanase. Using Nicotiana stem as an interscion, we produced tomato fruits on rootstocks from other plant families. These findings demonstrate that the process of cell-cell adhesion is a potential target to enhance plant grafting techniques.
