Pathogen infection influences a distinct microbial community composition in sorghum RILs

Abstract Aims The rhizosphere microbiome substantially affects plant health, yet comparatively little is known regarding the foliar community dynamics. Here, we examine relationship between microbiota and their response to natural infection by pathogens. Methods We established an experimental system using a set of sorghum recombinant inbred lines (RILS). These RILS included four models denoted as resistant, moderately susceptible highly susceptible. A combination 16S rRNA ITS gene amplicon approaches was used assess bacteria fungi, respectively, in samples. Results show that differs asymptomatic symptomatic RILs subsequent significant association found health microbial structure. Our analyses revealed several distinct fungal bacterial pathogens Gibberella Pantoea genera, which were associated with group. In addition these pathogens, also signatures for Ascochyta , pathogenic genus. Members genus Methylorubrum Hannaella, both exhibit growth-promoting (PGP) traits, resistant groups. data reveal numerous diverse taxa did not symptoms. taxonomic differences hosted RILs. Conclusions Together, suggest pathogen may result microbiota. results promote plants ability resist effects potentially contributing health.
