Common wheat (Triticum aestivum L.) is one of the most important food crops. Powdery mildew, caused by Blumeria graminis f. sp. tritici (Bgt), is one of the most serious diseases on wheat. In this study,
the changes of endogenous bacteria in root, stem and leaf tissues of wheat
infected and uninfected with powdery mildew were measured based on 16S rDNA.
Integration, OTU cluster analysis, taxonomic analysis, diversity index,
Shannon-Index curve, Rank-Abundance curve and PCoA analysis were carried out
for each sample, and the roots, stems and leaves of different tissue parts were
classified and summarized. The results showed that the infection of wheat
powdery mildew had a certain effect on endophytic bacteria in stem tissue.
There are also differences in the control and treatment of leaf tissue and root
tissue. This indicated that endophytic bacteria were distributed differently in
different parts of wheat.
