Influence of spore traits on the microbiome composition of plant organs.

Microbiomes from maize, soybean, and wheat were characterized in a long-term three-crop rotation research site to begin unraveling the origins of the fungal and bacterial communities of leaves, stems, and roots. Communities of plant organs were characterized across the growing season using amplicon sequencing. Communities differed across hosts, and among plant growth stages and organs. Roots consistently showed the highest number of bacterial OTUs compared to above-ground organs, whereas the alpha diversity of fungi was similar between above- and below-ground organs. The fungal taxa specific to roots, stems, or leaves were examined to determine if the specificity reflected their life histories based on previous studies. The analysis suggests that fungal spore traits are drivers of organ specificity in the fungal community. Understanding how community structure of specific crop organs is formed, will provide a critical resource for manipulations of microbial communities. The ability to predict how organ specific communities are influenced by spore traits will enhance our ability to introduce them sustainably.
