Pathogenic bacteria target plant plasmodesmata to colonize and invade surrounding tissues (Plant Cell)
Plant Science Research WeeklyPlasmodesmata are regulated channels that connect adjacent cells, allowing movement of metabolites, RNA, proteins, and pathogens. Plants close their plasmodesmata as part of their immune response, but this closure can be interfered with by pathogens. Aung et al. examined the repertoire of effector proteins…

Resistant tomato restricts colonization and invasion by the pathogen Ralstonia solanacearum at four organismal levels (J Exp Bot)
Plant Science Research WeeklyRalstonia solanacearum is a pathogenic bacterium that infects many important crop species, including tomato. Following invasion into the roots, the bacteria move upwards into the shoot and cause dramatic wilting. Previous studies have identified moderately and highly resistant lines. Here, Planas-Marquès…

Medicago-Sinorhizobium-Ralstonia co-infection reveals legume nodules as pathogen confined infection sites developing weak defenses (Curr. Biol.)
Plant Science Research WeeklyThe pathogenic bacterium Ralstonia solanacearum enters roots through wounds and also at root tips. It can also infect legume nodules. Benezech et al. investigated how this infection occurs, and how it is affected by and affects nitrogen fixation. The authors found that nodules are as permissive of Ralstonia…

High-frequency random DNA insertions upon co-delivery of CRISPR-Cas9 ribonucleoprotein and selectable marker plasmid in rice (Sci Reports)
Plant Science Research WeeklyGenome editing through CRISPR/Cas9 holds so much promise for plant breeders, including potentially the ability to overcome the public’s displeasure with conventional GMOs. Still, the gene-editing RNAs and enzymes must get into the plant cell in order to work. Banakar et al. have compared three methods…
