The Mechanisms, Research Status, and Future Prospects of m6A Modification in Breast Cancer.

N6-methyladenosine (m6A) modification is a significant methylation alteration frequently observed in eukaryotic RNAs, garnering considerable attention in the field of breast cancer research in recent years. The m6A modification profoundly influences the onset, progression, and prognosis of breast cancer by regulating RNA stability, translation efficiency, and degradation processes. Numerous studies have demonstrated that m6A regulatory factors, including METTL3, METTL14, and ALKBH5, play pivotal roles in breast cancer cells, affecting cell proliferation, metastasis, and drug resistance.

Phenotypic and genetic diversity of rhizobia isolated from nodules of the legume genera Astragalus, Lespedeza and Hedysarum in northwestern China.

Twenty-nine rhizobial isolates from root nodules of the wild Legumes Astragalus, Lespedeza and Hedysarum growing in the northwestern region of China, were characterized by numerical taxonomy, RFLP and sequencing of PCR-amplified 16S rDNA genes, and cross-nodulation with selected Legume species. Based on the results from numerical taxonomy, the isolates could be divided into two main groups (Clusters 1 and 2) and some single isolates at 82% similarity. CLuster 1 contained six isolates from Astragalus, Lespedeza and Hedysarum spp.
