A total of 39 isolates were obtained from the surface-sterilized
husked CT6919 seeds (Table 1). The isolates CT1 and
CT2 were obtained from the colonized roots of CT6919 seedlings
(Fig. 1A). The isolates CT3-CT19 correspond to the isolated
colonies that showed different pigmentation and aspect
under visual observation after 24 h of incubation on plates
spread with serial dilutions of CT6919 seed macerates. The
