Genetic diversity analysis and multi-fingerprint map construction of Naematelia aurantialba germplasm resources.

ABSTRACT: Due to its asexual reproduction characteristics, Naematelia aurantialba faces limitations in genetic diversity, germplasm identification, and intellectual property protection, necessitating molecular-level approaches to address these challenges. This study utilized resequencing data from 36 germplasm resources of N. aurantialba to conduct a population structure analysis and construct fingerprint maps based on core multinucleotide polymorphisms (MNPs), core single nucleotide polymorphisms (SNPs), and core insertions/deletions (INDELs), while also calculating genetic similarity among strains based on different variant sites. The results indicated that when K = 2, the genetic structure of individual strains was more distinctly divided, a finding corroborated by both the phylogenetic tree and
