Male sterility is classified as either cytoplasmic male (CMS) or genic (GMS). Generally, CMS involves mitochondrial genomes interacting with the nuclear genome, while GMS caused by genes alone. regulated multilevel mechanisms in which non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long (lncRNAs), and phased small interfering (phasiRNAs), have been proven to be critical elements. The development of high-throughput sequencing technology offers new opportunities evaluate genetic mechanism ncRNAs plant sterility. In this review, we summarize that regulate gene expression ways dependent on independent hormones, involve differentiation stamen primordia, degradation tapetum, formation microspores, release pollen. addition, key miRNA–lncRNA–mRNA interaction networks mediating plants are elaborated. We present a different perspective exploring ncRNA-mediated regulatory pathways control create male-sterile lines through hormones genome editing. A refined understanding ncRNA for sterile would conducive improve hybridization breeding.
