Periphytic Microbial Response to Environmental Phosphate (P) Bioavailability and Its Relevance to P Management in Paddy Fields.

ABSTRACT: Periphyton occurs widely in shallow-water ecosystems such as paddy fields and plays a critical part in regulating local phosphorus cycling. As such, understanding the mechanisms of biofilms' response to environmental phosphate (P) variability may lead to better perceptions of P utilization and retention in rice farms. The present study aims at exploring the biological and biochemical processes underlying periphyton's P buffering capability through examining changes in community structure, phosphorus uptake and storage, and molecular makeup of the exometabolome at different levels of P availability. Under stressed (both excessive and scarce) phosphorus conditions, we found increased populations of bacterial genera capable of transforming orthophosphate to polyphosphate, as well as mixotroph
