Interactions between endophytes (endophytic bacteria and fungi) plants are crucial in maintaining crop fitness agricultural systems, particularly relation to abundant rare subcommunities involved community construction. However, the influence of long-term fertilization on heterogeneous rhizosphere nitrogen phosphorus environments how these conditions affect key root their assembly mechanisms remain unclear. We studied 26th year a field experiment conducted greenhouse with varying levels (CKP0, CKP1, CNP0, CNP1, ONP0, ONP1) assess composition tomato impact yield. employed 16S rRNA fungal ITS region amplicon sequencing investigate endophytic subcommunities, network correlations, core subcommunity structures, species that enhance The results indicated organic manure fertilizers significantly increased soil content, availability (labile P, moderately labile non-labile P). These also affected (based Bray-Curtis distance) processes (βNTI) microbial subcommunities. both bacterial was primarily governed by dispersal limitation, structures being regulated content available (AN) P (MLP). Rare complemented ecological niches co-occurrence network, supporting functions enhancing stability. Nitrogen-adapting provided stronger predictive correlation for yield than phosphorus-adapting Additionally, three genera such as Arthrobacter, Microbacterium, Sphingobium were identified potentially improving improvement. findings revealed distinct fertilization, our understanding better management practices controlling improve intensive ecosystems.
