  • Genome editing technology is evolving fast, and many labs worldwide are generating crop plants with improved traits. If transgenes were used to generate the edits, foreign DNA must be effectively removed by outcrossing. After an evaluation of various technologies, we show that long-read whole-genome sequencing (WGS) is at present the only reliable approach to confirm the absence of foreign DNA. We suggest using long-read WGS before requesting exemption from classification as genetically modified organisms and provide a guide for interpreting WGS data.

  • Gibberellin (GA) is a plant hormone that plays an irreplaceable role in regulating growth and development. Now, the first fluorescent GA biosensor has been developed to visualize GA distributions at cellular resolution in Arabidopsis.

  • Although nectar is known to be important, for example in plant–insect interactions, little has been known about the mechanism of its secretion; sucrose phosphate synthases are now reported to be essential for the synthesis of the sucrose component of nectar and the transporter protein SWEET9 is shown to mediate sucrose export into the extracellular space of the nectary.

  • Fertilization involves species-specific interaction and eventually fusion of two gametic cells, and calcium signalling plays a key role in this process. Here, the authors monitor the changes in intracellular calcium that take place during fertilization of flowering plants and point to specific signatures associated with specific steps of the process.

  • Sugar efflux transporters are essential for diverse processes such as nectar production and seed and pollen development, as well for the maintenance of blood glucose levels in animals. These authors identify and characterize a novel sugar transporter family, SWEET, and show that several Arabidopsis, rice and metazoan homologues mediate glucose transport. In addition, some of these transporters are exploited by plant pathogens for nutritional gain and virulence.

  • Transcription activator-like effectors contribute to virulence of theXanthomonas strain responsible for bacterial blight in cotton. Here Cox et al. show that the XanthomonasAvrb6 effector induces expression of the cotton SWEET10 sugar transporter and that this induction promotes disease.

  • Characterizations of durable resistance genes in crop plants are coming to the fore. A new study characterizing the wheat gene Lr67 shows that how a plant manages sugar transport affects the ability of a broad group of fungal pathogens to colonize their host.

  • Single fluorescent protein biosensors are susceptible to expression and instrumental artifacts. Here Ast et al. describe a dual fluorescent protein design whereby a reference fluorescent protein is nested within a reporter fluorescent protein to control for such artifacts while preserving sensitivity and dynamic range.

  • The X-ray crystal structure is presented of a seven-transmembrane eukaryotic SWEET glucose transporter, revealing the link between seven-transmembrane eukaryotic SWEETs and their three-transmembrane bacterial homologues and providing insight into eukaryotic sugar transport mechanisms.
