1. An example of a gene regulatory network (figure courtesy of Siobhan Brady and Allison Gaudinier,
University of California-Davis, USA).

2. A comparison between control and genome-edited rice in the field shows that genome editing of
pathogen-responsive elements in rice SWEET (sugar transporter) genes leads to broad-spectrum
resistance to bacterial blight (image courtesy of Bing Yang, University of Missouri, USA).

3. No-till winter wheat seeded into standing stubble for snow trapping, spring, north-central
Saskatchewan (image courtesy of Brian Fowler, University of Saskatchewan, Canada).

4. Model showing that vacuolar and secreted purple acid phosphatases (PAPs) are upregulated by Pi-
deprived plants to scavenge Pi from intra- & extracellular Pi-esters (figure courtesy of William Plaxton,
Queen’s University, Kingston, Ontario, Canada).
5. Hyphal network of Pseudozyma flocculosa developing around powdery mildew colonies (image

throughput genetic sequencer (image courtesy of Andy Davis, John Innes Centre, UK). (b) Yellow rust
spores from inside a wheat leaf (SEM image courtesy of Kim Findlay, John Innes Centre, UK).
