摘要
Seed, root, stem, petiole and leaf tissues of Bt and non-Bt cotton (Krishidhan variety) were screened for the presence of symptomless endosymbiotic fungi (endophytes). All the tissue types of both Bt and non-Bt plants harboured endophytes. Although the number of endophyte species isolated from the two types of plant did not vary much, the number of isolates of endophytes was higher in all non-Bt tissues when compared with the respective Bt tissues. The lower infection frequency observed for the Bt cotton tissues may not be due to a direct effect of Bt gene insertion, but possibly due to the Bt plant warding off insect pests.
