Phosphorus (P) represents a key growth-limiting factor for plants in sandy soils, yet systematic understanding of P-cycling microbial communities including their composition, ecological functions, and responses to vegetation succession remains limited. We conducted cross-transplant experiments using dominant species from different successional stages under Caragana microphylla plantations in the Horqin Sandy Land, and assessed soil properties, enzyme activities, organic P mineralization and inorganic P solubilization rates, and phoD\/gcd-harboring microbial communities. Encroachment by late-successional species increased soil nutrients, biological activities, phoD\/gcd-microbial abundances, and soil P transformation rate, and restructured microbial communities while preserving core taxa. Soil properties (pH, electrical conductivity, organic matter, total nitrogen, total P, available potassium, available P, and NH4+-N) significantly influenced phoD community composition. Notably, P availability was primarily driven by phoD-mediated organic P mineralization, with gcd-mediated solubilization playing a minor role. These changes enhanced alkaline phosphatase activity and P availability, promoting plant growth and new species colonization, thereby establishing a positive plant\u2013soil\u2013microbe feedback that drives succession. The identified dominant phoD\/gcd taxa provide candidates for developing microbial inoculants to accelerate vegetation restoration.<\/jats:p>","DOI":"10.3390\/plants15142175","type":"journal-article","created":{"date-parts":[[2026,7,16]],"date-time":"2026-07-16T01:05:07Z","timestamp":1784163907000},"page":"2175","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Impact of Dominant Species Shift in Herbaceous Vegetation Beneath Sand-Fixing Plantations on Soil Microbial Communities Involved in Organic P Mineralization and Inorganic P Solubilization"],"prefix":"10.3390","volume":"15","author":[{"given":"Herui","family":"Li","sequence":"first","affiliation":[{"name":"College of Life and Health Sciences, Northeastern University, Shenyang 110169, China"},{"name":"Liaoning Province Key Laboratory of Bioresource Research and Development, Northeastern University, Shenyang 110169, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Life and Health Sciences, Northeastern University, Shenyang 110169, China"},{"name":"Liaoning Province Key Laboratory of Bioresource Research and Development, Northeastern University, Shenyang 110169, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Xiang","sequence":"additional","affiliation":[{"name":"College of Life and Health Sciences, Northeastern University, Shenyang 110169, China"},{"name":"Liaoning Province Key Laboratory of Bioresource Research and Development, Northeastern University, Shenyang 110169, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2481-8777","authenticated-orcid":false,"given":"Chengyou","family":"Cao","sequence":"additional","affiliation":[{"name":"College of Life and Health Sciences, Northeastern University, Shenyang 110169, China"},{"name":"Liaoning Province Key Laboratory of Bioresource Research and Development, Northeastern University, Shenyang 110169, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"118","DOI":"10.1002\/ldr.2190","article-title":"Combating aeolian desertification in northern China","volume":"26","author":"Wang","year":"2015","journal-title":"Land Degrad.
