DOI: 10.1002/mbo3.1202
Abstract: Antibiotics are sprayed on apple and pear orchards to control, among other pathogens, the bacterium Erwinia amylovora, the causative agent of fire blight. As with many other pathogens, we observe the emergence of antibiotic‐resistant strains… read more here.

DOI: 10.1007/s00299-022-02869-8
Abstract: KEY MESSAGE pPPO16, the first Ea-inducible promoter cloned from apple, can be a useful component of intragenic strategies to create fire blight resistant apple genotypes. Intragenesis is an important alternative to transgenesis to produce modified… read more here.

DOI: 10.1007/s00438-017-1376-3
Abstract: The bacterial enhancer binding protein (bEBP) HrpS is essential for Erwinia amylovora virulence by activating the type III secretion system (T3SS). However, how the hrpS gene is regulated remains poorly understood in E. amylovora. In… read more here.

DOI: 10.1007/s42161-020-00583-6
Abstract: Previous studies have shown that the hypersensitive response and pathogenicity (hrp)-type III secretion system (T3SS) is activated by the bacterial alarmone (p)ppGpp, which mediates the stringent response in nutrient starvation conditions in Erwinia amylovora. ATP… read more here.

DOI: 10.1007/s42161-024-01692-2
Abstract: A greater genetic diversity is essential for disease resistance in particular, and intergeneric hybridization makes this possible. The genus Cydomalus (syn: Cydolus), which is frequently used as rootstock, was derived from intergeneric hybridization between Cydonia… read more here.
