  • Grafting is an agricultural technique that fuses scion and rootstock tissue from different plants. Here the authors report that autophagy is induced during grafting, promoting callus formation and contributing to tissue connectivity.

  • Homocitrate is an essential component of the enzyme nitrogenase, which is required for nitrogen fixation. However, the NifV gene, which encodes homocitrate synthase, is not present in most rhizobial species that require symbiotic association with legumes to perform efficient nitrogen fixation. The FEN1 gene of a model legume, Lotus japonicus, is now shown to overcome the lack of NifV in rhizobia for symbiotic nitrogen fixation.

  • Plant-associated fungi range from pathogens to mutualists. Here the authors identify a gene cluster in a Colletotrichum tofieldiae strain that is required to allow the fungus to transition from a mutualist to a pathogen depending on the nutritional status of the host.

  • This study examined how changing the water-glycerol solvent composition affects the self-healing and viscoelastic properties of self-healing gels, which have host-guest inclusion complexes as reversible crosslinks. Increasing glycerol concentration in the mixture solvent reduced hydrophobic interactions between β-cyclodextrin and adamantane, lowering the association constant of host-guest inclusion complexes. The weakened hydrophobic interaction hinders complex recombination and enhances the mobility of the network chains. Consequently, the enhancement of mobility improved the healing ratio because the interfacial diffusion of the chains was promoted at the repair interfaces.
