A simple and effective method for total RNA isolation of appressoria in Magnaporthe oryzae.

ABSTRACT: Appressorium formation is an important event in establishing a successful interaction between the rice blast fungus, Magnaporthe oryzae, and its host plant, rice. An understanding of molecular events occurring in appressorium differentiation will give new strategies to control rice blast. A quick and reliable method to extract total RNA from appressorium is essential for studying gene expression during appressorium formation and its mechanism. We found that duplicate film is an efficient substratum for appressorium formation, even when inoculated with high density conidia. When inoculated with conidia at 1x10(6) ml(-1), the percentages of conidium germination and appressorium formation were (97.98+/-0.67)% and (97.88+/-0.45)%, respectively. We applied Trizol before appressorium collection
