- •
Acidovorax avenae subsp. avenae had the ability to produce gibberellic acid 1, gibberellic acid 3 and indole-3-acetic acid.
- •
High temperature exacerbated Aaa necrosis and chlorosis disease symptoms of creeping bentgrass.
- •
Creeping bentgrass ‘Tyee’ was more resistant to Aaa infection than ‘Penn-A4’ which could be associated with differential accumulation of SA and JA in plant tissues.
- •
The involvement of gibberellic acids in this pathogen system could contribute to the etiolation symptom.
