Abstract: Biostimulants, as a category of biological agents containing microbial inoculants and active substances, are emerging as a promising solution in the field of saline-alkali land bioremediation. Su100 is a novel endophytic fungus belonging to the genus Mollisia , whose functions have not yet been extensively deciphered. In this study, we found Su100 fermentation broth (SFB) significantly enhanced grain yield of 'Yannong 1212’, 'Jimai 22’, 'Jimai 60’, and 'Hangmai 802’ by 68.30, 27.89, 14.73, and 25.51%, respectively. Moreover, the nutritional quality and processing quality in the grains of 'Yannong 1212’ were also significantly improved, indicating that SFB could synergistically enhance both the yield and quality of wheat. Further physiological and transcriptomic analysis of root suggested that SFB mitigates saline-alkali stress by enhancing N and P uptake and remodeling phenylpropanoid and fatty acid metabolism. Our study elucidates the function of Mollisia fungi and supports the development of microbial-based biostimulants for sustainable agriculture.
