[...]research involving the identification and characterization of species associated with bamboo is necessary in order to use these compounds in the biocontrol of pathogens in cultivated plants in the future (Oyetayo et al. 2009; Ebada et al. 2011; Li et al. 2012). Melanin plays a structural part in strengthening the appressorium and forms an impermeable layer to prevent leakage of osmolytes, which generate the substantial internal turgor (Wilson & Talbot 2009). [...]the loss or blockade of melanin in the colony also implies the loss of pathogenicity (Yan & Talbot 2016; Oses-Ruiz et al. 2017). [...]the development of biological control techniques that provide blockade of melanin in P. oryzae colonies could provide improvements in rice production. [...]research involving identification of endophytic fungi and their antagonisms between P oryzae are necessary in order to develop natural products in the future that may be inhibitors of pathogen growth under natural conditions, or even use these endophytes as growth resistance inducers. [...]the objective of this study was to identify and morphologically characterize endophytic fungi of Bambusa oldhamii Munro and to evaluate possible antagonism to P oryzae, for use in future studies on resistance and plant growth promotion.
