However, the dynamic effects of <i>Pugionium</i> Gaertn. growth on soil microbial C:N:P stoichiometric ratios and their primary driving factors in native desert ecosystems remain poorly understood. This study aimed to clarify the stage-dependent regulation of microbial C:N:P stoichiometry by <i>Pugionium</i> Gaertn. in native desert ecosystems. This study examined representative <i>Pugionium</i> Gaertn. (<i>P. cornutum</i> and <i>P. dolabratum</i>) in northwestern China's desert regions, based on investigations conducted during 2022-2023, conducting systematic analysis of variations in rhizosphere soil microbial biomass C, N, and P levels, C:N:P stoichiometric ratios, fungal and bactBiologyEffects of Growth Stages of &lt;i&gt;Pugionium&lt;/i&gt; Gaertn. on Soil Microbial Biomass C:N:P Stoichiometric Ratios and Homeostasis in Northwestern China's Desert Regions.PMC129382742025MS03091317605702021CG0023236074232360751Zhang FYang ZZhang DHao LHuang XZhang XNing KfalseEffects of Growth Stages of &lt;i&gt;Pugionium&lt;/i&gt; Gaertn. on Soil Microbial Biomass C:N:P Stoichiometric Ratios and Homeostasis in Northwestern China's Desert Regions.Microbial stoichiometry serves as a fundamental indicator of nutrient limitations in microbial communities.
