TABLE 1.
Induction of hypersensitive response (HR) on solanaceous crops by Clavibacter michiganensis mutant strains
| Genotype | Strain name | pCM1 | pCM2 | PI | Tomato | Pepper | Eggplant |
|---|---|---|---|---|---|---|---|
| Cm | NCPPB 382 | + a | + | + | N b | N | HR b |
| Cm−pCM2 | CMM101 | + | − | + | N | N | HR |
| Cm−pCM1 | CMM102 | − a | + | + | N | N | HR |
| Cm−pCM1,−pCM2 | CMM100 | − | − | + | N | N | HR |
| Cm∆PI , −pCM2 | CMM30‐18 | + | − | − | N | N | N |
| Cm∆PI | CMM27 | + | + | − | N | N | N |
a
+ or − indicates the presence/absence of the pCM1, pCM2, and chp/tomA pathogenicity island (PI) in the strain.
b
HR, localized cell death was observed within 72 h after infiltrating OD600 = 0.1 of the indicated strain; N, no response was observed.
