These rhizosphere communities contribute to nutrient cycling and rice productivity. The use of fertilizers is a common agricultural practice in rice paddy fields. However, the long-term impact of the fertilizers usage on the rhizosphere microbial communities at different rice developmental stages remains poorly investigated. Here, we examined the effects of long-term (27 years) N and NPK-fertilization on bacterial and archaeal community inhabiting the rice rhizosphere at three developmental stages (tillering, panicle initiation and booting) in the Senegal River Delta.ResultsWe found that the effect of long-term inorganic fertilization on rhizosphere microbial communities varied with the rice developmental stage, and between microbial communities in their response to N and NPK-fertilization. The microbial communities inhabiting the rice rhizosphere at panicle initiation appear to be more sensitive to long-term inorganic fertilization than those at tillering and booting stages. However, the effect of developmental stage on microbial sensitivity to long-term inorganic fertilization was more pronounced for bacterial than archaeal community. Furthermore, our data reveal dynamics of bacteria and archaea co-occurrence patterns in the rice rhizosphere, with differentiated bacterial and archaeal pivotal roles in the microbial inter-kingdom networks across developmental stages.ConclusionsOur study brings new insights on rhizosphere bacteria and archaea co-occurrence and the long-term inorganic fertilization impact on these communities across developmental stages in field-grown rice. It would help in developing strategies for the successful manipulation of microbial communities to improve rice yields. specialized Metabarcoding 16S rRNA gene Fertilization Inter-kingdom network SENEGAL ZONE SAHELIENNE 076 074 18 1 42 [17 p.] 2023 https://www.documentation.ird.fr/hor/fdi:010087786 10.1186/s40793-023-00500-1 [F B010087786] https://www.documentation.ird.fr/hor/fdi:010087786 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2023-07/010087786.pdf IRD - Base Horizon / Pleins textes 2023-07-06 2026-06-12 fdi:010087786 fre
