First report of Acidovorax avenae ssp. avenae on rice in Italy.

Abstract

In 2003, incidence of rice panicle sterility in Lombardy, northern Italy was 1.8%, and the estimated crop loss was 1.5%. The spatial distribution of sterile panicles suggested a seedborne bacterial aetiology. The causal agent was identified as A. avenae subsp. avenae based on colony characteristics, poly-β-hydroxybutyrate accumulation and PCR. This is thought to be the first report of A. avenae subsp. avenae on rice in Italy.
