Hydrogen Sulfide Alleviates Alkaline Salt Stress by Regulating the Expression of MicroRNAs in Malus hupehensis Rehd. Roots.

ABSTRACT: Malus hupehensis Rehd. var. pingyiensis Jiang (Pingyi Tiancha, PYTC) is an excellent apple rootstock and ornamental tree, but its tolerance to salt stress is weak. Our previous study showed that hydrogen sulfide (H₂S) could alleviate damage in M. hupehensis roots under alkaline salt stress. However, the molecular mechanism of H₂S mitigation alkaline salt remains to be elucidated. MicroRNAs (miRNAs) play important regulatory roles in plant response to salt stress. Whether miRNAs are involved in the mitigation of alkaline salt stress mediated by H₂S remains unclear. In the present study, through the expression analysis of miRNAs and target gene response to H₂S and alkaline salt stress in M. hupehensis roots, 115 known mi
