Maize Phyllosphere Microbial Community Niche

The phyllosphere hosts a variety of microorganisms, including Background bacteria, which can play a positive role in the success of the host plant. Bacterial communities in the phylloplane are influenced by both biotic and abiotic factors, including host plant surface topography and chemistry, which change in concert with microbial communities as the plant leaves develop and age. : We examined how the L. leaf microbial community Methods Zea mays structure changed with plant age. Ribosomal spacer length and scanning electron microscopic imaging strategies were used to assess microbial community composition across maize plant ages, using a novel staggered experimental design. : Significant changes in community composition were observed for Results both molecular and imaging analyses, and the two analysis methods provided complementary information about bacterial community structure within each leaf developmental stage. : Both taxonomic and cell-size trait patterns provided evidence for Conclusions niche-based contributions to microbial community development on leaves. 1,2 1,3 1 1,4
