Descripción

Rice blast caused by the Magnaporthe oryzae pathogen is a major disease in this crop, and may cause devastating losses. This study aimed to investigate the profile of Waitea circinata mycorrhiza volatile compounds in antagonism to M. oryzae, under different growth periods and temperatures, using a completely randomized design. Volatile organic compounds were extracted by headspace solid phase microextraction and analyzed by gas chromatography mass spectrometry, while multidimensional scaling was used to compare the produced volatile organic compounds. The main compounds responsible by the antagonism to M. oryzae were longifolene, trans-β-farnesene, (Z)-α-bisabolene and δ-amorphene, which can be used as biofungicides and incorporated into rice blast management strategies.
