“…A fungus identified as A. oryzae (MMAO1) was isolated from rice hulls, and this fungus produced a dimeric diketopiperazine compound, ditryptophenaline, 7,9-dihydroxy-3-(1H-indol-3-ylmethyl)-8-methoxy-2,3,11,11a-tetrahydro-6H-pyrazino[1,2-b]isoquinoline-1,4-dione, cyclo-(Trp-Tyr), cyclo-(Pro-Val), α-cyclopiazonic acid, (bismethylthio)gliotoxin, pseurotin A, kojic acid, linoleic acid, and uridine (Shaaban et al 2014 ). Since the isolate was from rice hulls in a domesticated field, it was probably an A. flavus , but it could also be an A. nomius since pseurotin A has only been found once in A. flavus (see Varga et al 2011b ; Rodríguez et al 2015 ).…”
