Abstract:
... Sarocladium oryzae is a common plant pathogen causing rice sheath rot worldwide. Sarocladium attenuatum has been identified as one of the causal agents of rice sheath rot and was synonymized under S. oryzae. The analysis of 102 Sarocladium strains associated with rice in Taiwan, based on morphological features and multilocus molecular phylogeny, reveals that these two species are distinct and that ...
