Resumen:
Exudates of Rhodotorula mucilaginosa, a yeast commonly found in the rhizosphere, increased hyphal
length of the arbuscular mycorrhizal (AM) fungi Gigaspora rosea and Gigaspora margarita. Rhodotorulic
acid (RA), a siderophore compound obtained from R. mucilaginosa exudates, increased hyphal length and
branching. Thus, the increase in the number of entry points and the higher AM root colonization of
tomato plants in the presence of RA can at least partially be explained by the positive effect of RA on the
pre-symbiotic stages of the AM fungi.
