摘要：

The role of endoglucanases (endoglucanases Z and Y) in Erwinia chrysanthemi pathogenicity on Saintpaulia ionantha was assessed by mutagenizing cloned eel genes (celZ and celY) and recombining them with the chromosomal alleles. Strains with an Omega interposon in celZ, a deletion in celY, or a double eel mutant were as virulent as the wild-type strain. However, in the strain with a deletion in celY, a delay in the appearance of symptoms was observed, and then maceration progressed as in plants infected with the wild-type strain, suggesting that E. chrysanthemi endoglucanases play a minor role in soft rot disease development.
