Climatic Variables and Virulence May Contribute to the Population Dynamics of Pyricularia oryzae at Local Scale.

ABSTRACT: Rice blast disease, caused by Pyricularia oryzae Cavara, is the most threatening rice pathogen in Italy. The development of resistant cultivars is a sustainable approach to mitigate yield losses. However, P. oryzae genomic plasticity often allows rapid adaptation to host resistance. Understanding the population structure of plant pathogens is crucial for assessing their genetic diversity and implementing durable management strategies. Despite first attempts from Piotti et al. (2005) to study the Italian P. oryzae population, a gap in current local P. oryzae genetic variability still needs to be addressed. Here, the population structure of a large set of P. oryzae isolates from diseased rice panicles, collected in five different Italian regions between 2011-2012 and 2020-2022, was character
