Dynamics of spatial and temporal population structure of Pyricularia oryzae in Taiwan.

Background: To gain a better understanding of how Pyricularia oryzae population shifts is important for selecting suitable resistance genes for rice breeding programs. However, the relationships between P. oryzae pathogenic dynamics, geographic distribution, rice varieties, and timeline are not well studied.
