Abstract:

Interactions between endophytes and host plants could be affected by various factors such as the genetic modification of plants. In the present study, impact of genetic modification (Bacillus thuringiensis (Bt) cry proteins) of maize plants on the diversity of fungal endophytes was investigated. This was carried out by assessing diversity of fungal endophytes associated with a Bt-maize (MON810) and its isogenic, non-transgenic parental line at pre-flowering (50 days) and post-flowering (90 days) developmental stages. Fungal communities inhabiting the phyllosphere of Bt-maize and its isogenic parental line were isolated and identified. Twenty-one isolates were obtained from the shoots of Bt-maize and 27 from its isogenic parental line, representing 14 genera and 19 OTUs. The most frequently isolated groups were Fusarium from tassels as well as Epicoccum and Alternaria from leaves. In both cultivars, the leaves had the highest fungal diversity. Results obtained in the study indicate that there was no significant difference between isolates from Bt-maize and its parental line, which means the genetic modification did not affect the diversity of cultivable fungi associated with the Bt-maize genotype. This study further highlights the diversity of fungal endophytes that may benefit their hosts through nutrient cycling and biological control of diseases.
