“…Previous studies have shown that the genetic diversity of species dominated by self-crossing mainly exists among populations, while that of outcrossing species mainly exists within populations (Xiang et al 2020 ; Zhou et al 2020 ). In this study, POPGENE software analysis showed that the genetic differentiation of A. tsao-ko mainly existed within populations (Table 5 ), which was consistent with the result by RAPD and SSR markers (Lu et al 2018 , 2021 ).…”

Amomum tsao-ko Crevost & Lemarié is an important crop that has been widely used in traditional Chinese medicine and daily diets for a long time. In this study, the genetic diversity and relationships of eight cultivated populations of A. tsao-ko grown in Southwest China were examined using sequencerelated amplified polymorphism (SRAP) and intersimple sequence repeat (ISSR) markers. The results showed that 139 (99.29%) of 140 and 185 (99.46%) of 186 bands were polymorphic by SRAP and ISSR primers amplification, respectively. The polymorphic information content of detected bands were 0.270 (SRAP) and 0.232 (ISSR), respectively. The average Nei's gene diversity (H = 0.217) and Shannon's information index (I = 0.348) at the species level generated by SRAP primer were higher than those by ISSR analysis (H = 0.158, I = 0.272). Genetic differentiation coefficients and molecular variance analysis (AMOVA) indicated that the genetic variance of A. tsao-ko mainly occurred within populations rather than among populations. The high genetic identity among populations was revealed by SRAP (0.937) and ISSR (0.963). Using UPGMA cluster analysis, principal coordinate analysis, and population structure analysis, the accessions were categorized into two major groups. Overall, results obtained here will be useful for A. tsao-ko germplasm characterization, conservation, and utilization.

“…Due to both high genetic diversity and consistent amplification, ITS is a barcoding region that has been selected and used by many previous studies on the identification and investigation of the relationship among a group of taxa on many different subjects [31][32][33] . On the contrary, the SCoT product is amplified from a non-specific single primer [4][5][6][7][8] , so the appearance of bands will also vary significantly among other taxa and components of primer sets. In another way, from the practical study, we also found that the reliability of the SCoT technique also depended on subjectively reading the bands.…”

“…Thus, the genetic examination is directly related to the expressed characteristics rather than random DNA fragments in the genome 5-7 . Zhou et al 8 determined the genetic relatedness among 168 mangoes (Mangifera indica L.) germplasm resources using this technique. From 337 DNA bands created by 45 SCoT primers, 34 seedling germplasm resources could be identified as potential parents or sister lines.…”

Background and Objective: The genus Mangifera is a group of fruit trees with high economic and export value in Vietnam. However, the current management of the diversity of mango cultivars and selection of propagation materials is mainly based on morphological and agronomic characteristics. There is still a lack of molecular information for more accuracy and quick development of mangoes in Vietnam. In this study, the sequence-based barcoding method and PCR-based SCoT technique were used for the molecular identification of some mango cultivars in Vietnam. Materials and Methods: Nine mango cultivars of Southern Vietnam i.e., XoaiHoa Loc, Xoai Cat Chu,

IntroductionMango is a vital horticultural fruit crop, and breeding is an essential strategy to enhance ongoing sustainability. Knowledge regarding population structure and genetic diversity in mango germplasm is essential for crop improvement.MethodsA set of 284 mango accessions from different regions of the world were subjected to high-throughput sequencing and specific-locus amplified fragment (SLAF) library construction to generate genomic single-nucleotide polymorphism (SNP).ResultsAfter filtering, raw data containing 539.61 M reads were obtained. A total of 505,300 SLAFs were detected, of which, 205,299 were polymorphic. Finally, 29,136 SNPs were employed to dissect the population structure, genetic relationships, and genetic diversity. The 284 mango accessions were divided into two major groups: one group consisted mainly of mango accessions from Australia, the United States, Cuba, India, Caribbean, Israel, Pakistan, Guinea, Burma, China, and Sri Lanka, which belonged to the Indian type (P1); the other group contained mango accessions from the Philippines, Thailand, Indonesia, Vietnam, Cambodia, Malaysia, and Singapore, which belonged to Southeast Asian type (P2). Genetic diversity, principal component analysis (PCA), and population structure analyses revealed distinct accession clusters. Current results indicated that the proposed hybridization occurred widely between P1 and P2.DiscussionMost of the accessions (80.99%) were of mixed ancestry, perhaps including multiple hybridization events and regional selection, which merits further investigation.
