Reshaping the Primary Cell Wall: Dual Effects on Plant Resistance to Ralstonia solanacearum and Heat Stress Response

Henri Desaint et al. show that mutating the cellulose synthase subunit CESA3 enhances resistance to Ralstonia solanacearum in Arabidopsis thaliana, even under heat stress, offering insights into breeding heat-resilient resistance against this pathogen amid climate change.

Rhizobial Secretion of Truncated Exopolysaccharides Severely Impairs the​ Mesorhizobium-Lotus Symbiosis​

Todd Wightman et al. used a suppressor screen to show that the severe symbiotic phenotype of the exoU mutant was due to the secretion of an acetylated pentasaccharide, as both monomers and oligomers, by the same Wzx/Wzy system that transports wild-type exopolysaccharide.

Immunolocalization and Ultrastructure Show Ingestion of Cry Protein Expressed in Glycine max by Heterodera glycines and Its Mode of Action

Soybean plants expressing Bacillus thuringiensis Cry14Ab show promise for controlling the soybean cyst nematode, an adaptive pest. R. Howard Berg et al. highlight Cry14Ab’s unique midgut-disrupting action, revealed through electron microscopy, offering a novel transgenic approach distinct from native resistance sources.
