| Studies on beneficial microorganisms associated to crops have traditionally used culture- based techniques, which are known to sample only a minute portion of the microbial community. Sugarcane has been a target of such researches, since there are repeated evidences of a microbial community supporting plant development and sustaining high yields under conditions of little or no fertilization. However, none study has taken into consideration the diversity or the qualitative/quantitative microbial communities in the biology of the plant. We intend to unravel the microbial community associated to sugarcane plants cultivated for four cuts without fertilization. Exophytic and endophytic microbial communities were evaluated in root, stalk, leaf and young shoot. We also accessed the microbial communities of bulk soil. Illumina platform was used to sequence 16S and ITS amplicons. Our data revealed that factors driving the community composition differ between prokaryote and fungi. Although the microbial diversity is huge for any tissue, a core microbiome comprised of less than 1% of the diversity represents 65% to 96% relative abundance of the total microbial diversity. Interestingly, the most abundant microbial groups are not the ones that have been isolated and evaluated over the past decades in sugarcane. The data open a new window for the investigation of untargeted microbes potentially beneficial for sugarcane growth and development. | |
