摘要

虽然丛枝菌根真菌(AMF)共生的生态强化为作物获取磷提供了一条可持续的途径,但在集约化管理下,宿主基因型在塑造AMF群落中的作用尚不清楚。本研究对两种不同磷利用效率(CL3:低磷敏感;CL40:耐低磷)。结果表明,CL3具有较高的AMF定殖率和α-多样性,ES群落以肾小球科植物为主。CL40的根际土壤pH值较低,有效磷含量较高,有机酸(如柠檬酸和草酸)含量较高,胞外酶活性较高,表明CL40对磷的动员采取“高酶高有机酸”的策略。相比之下,CL3依赖于amf介导的磷吸收,并得到了shiminic酸含量升高和肾小球科植物招募的支持。pH、有效磷和有机酸是根际真菌群落分化的关键驱动因素。这些研究结果表明,宿主基因型通过不同的p获取策略调节AMF共生,强调了品种特异性根微生物相互作用在可持续农业中的重要性。

Differential AMF diversity in the rhizosphere and endosphere of two Camellia oleifera cultivars
While ecological intensification through arbuscular mycorrhizal fungi (AMF) symbiosis offers a sustainable pathway for phosphorus (P) acquisition in crops, the role of host genotype in shaping AMF communities under intensive management remains unclear. This study investigated the root endosphere (ES) and rhizosphere soil (RS) AMF communities of two Camellia oleifera cultivars with contrasting phosphorus-use efficiencies (CL3: low-P-sensitive; CL40: low-P-tolerant) in a field experiment. The result revealed that CL3 exhibited significantly higher AMF colonization rates and α-diversity, with ES communities dominated by Glomeraceae. Rhizosphere soil of CL40 showed lower pH, higher available phosphorus (Avail-P), organic acids (e.g., citric and oxalic acids), and extracellular enzyme activities, suggesting a “higher enzyme activity and organic acid” strategy for P mobilization. In contrast, CL3 relied on AMF-mediated P uptake, supported by elevated shikimic acid content and Glomeraceae recruitment. pH, Avail-P, and organic acids as key drivers of AMF community divergence in rhizosphere. These findings demonstrate that host genotypes regulate AMF symbiosis through distinct P-acquisition strategies, emphasizing the importance of cultivar-specific root-microbe interactions in sustainable agriculture.
