Knots induced by Psv NCPPB 3335 and derivative strains with altered virulence or pathogenicity in woody olive plants at 90 dpi. Pictures correspond to typical symptoms induced by the wild-type strain (NCPPB 3335) and derivative mutants for genes iaaMH1 (IAA production), hrpR (T3SS), dgcP (c-di-GMP metabolism) and antA (WHOP), as well as a Psv NCPPB 3335 derivative cured of pPsv48A, a plasmid encoding the biosynthetic gene ptz, and defective in cytokinins (CKs) production. Negative control, plant inoculated with sterile MgCl2.
