The paper investigates the transmission routes of Pseudomonas syringae strains causing zucchini diseases, finding that VCZ strains are predominantly transmitted via floral pathways while BLS strains use pericarp transmission.

The paper quantifies the efficiency of different transmission routes for Xanthomonas citri pv. fuscans and other seed-borne bacteria to bean seeds, finding the vascular route most efficient and identifying plant immunity as a bottleneck.

This study uses transcriptomics to compare the HrpG regulon across 17 Xanthomonas strains, revealing diverse gene regulation beyond the T3SS and T3Es.
