Other claims from this paper (13)
- Method / resource In silico mining of the guava genome yielded 75,084 new SSR markers.
- Method / resource Of 72 amplified novel g-SSR markers, 53 showed polymorphism among guava genotypes.
- Observation The 53 polymorphic g-SSR markers had an average of 3.04 alleles per locus across 35 selected guava genotypes.
- Observation Mean major allele frequency across the guava genotypes was 0.73.
- Observation Mean gene diversity across the guava genotypes was 0.38.
- Observation Mean observed heterozygosity across the guava genotypes was 0.13.
- Observation Mean polymorphism information content across the guava genotypes was 0.33.
- Method / resource Transferability of the novel g-SSR loci across wild Psidium species was 45.83% to 90.28%.
- Method / resource Only four of the novel g-SSR markers could differentiate between two Syzygium species.
- Observation A neighbour-joining tree classified 35 guava genotypes into four clades and one outlier.
- Observation Wild Psidium species are genetically unique compared with cultivated guava genotypes.
- Observation Model-based structure analysis divided the guava genotypes into two distinct genetic groups.
- Observation AMOVA and PCoA indicate substantial genetic diversity among the selected guava genotypes, including wild Psidium species.
