Population genetics studies genetic variation involving gene and allele frequencies in spatial and temporal space. Genetic information can be used in conservation management through identification of phylogenetic tree reconstructions, genetic distance, genetic structure, and haplotype connectivity to maintain population existence. The samples used were primary genetic data of Siganus canaliculatus taken from Indonesian waters and secondary data accessed from the BOLD SYSTEM database from several locations, namely Indonesia, China, and Bangladesh. This research was conducted to determine the kinship of Siganus canaliculatus in Indonesia, China, and Bangladesh through genetic analysis. The results of genetic distance analysis showed that the baronang fish samples from China and Bangladesh had a close relationship with a value of 0.0534 while samples from Indonesia and Bangladesh had the farthest relationship with a value of 0.8212. Reconstruction of the phylogeny tree at maximum likelihood can show convergence within the same clade. The results of the reconstruction of the phylogeny tree showed that the species from Ambon, Bali, and Lombok came from the same clade while samples from Bangladesh had different clades with the furthest distance. The results of structural analysis and genetic diversity showed that samples from Bangladesh, China, and Indonesia had different DNA characteristics. This is correlated with the form of network integration in haplotype connectivity analysis.

“…As population genetic studies have progressed, there has been an increasing appreciation for the value of regional patterns of genetic variants in adaptive and neutral molecular markers in the identi cation of strong seed zones for genetic conservation and restoration efforts. As DNA based markers have become more widely available, several indigenous tree species have been the subject of genetic studies (Hartvig et al 2018;Castro et al 2021). Researchers can analyse the present in uence of drift and gene ow on populations using polymorphic markers inherited from both parents.…”

The endemic and precious timber Pterocarpus santalinus L. f. (Red sanders) is a drought hardy tree species for conservation in peninsular India due to its high risk of illegal timber harvest. It is only found in Eastern Ghats of India, and has become threatened owing to overexploitation of its valuable timber. The development of genomic resources, particularly simple sequence repeat (SSR) markers, is essential for strict implementation of in situ conservation measures and application of DNA information based red sanders genetic resource management. However, a lack of genomic data and e cient molecular markers limit the study of its spatial and temporal population genetic structure, identi cation of diversity hotspots and tree improvement. The current study aims at comprehensive molecular characterization of red sanders and the somatic chromosome counts, ow cytometry and EST-SSR analyses. The results revealed that red sanders is diploid with 2n=20 and the 2C genome size was 0.7872 ± 0.0561pg for the rst time in this species. A total of 3128 EST-SSRs were detected based on 25,854 de novo assembled unigenes from transcriptome data and primer sets designed for 1953 SSRs. Fifty-nine EST-SSR markers were evaluated for polymorphism in the natural populations of red sanders and 13 were found to be suitable for genetic analysis. Two major transcription factor families bHLH and ERF, responsible for abiotic stress and secondary metabolite synthesis were analysed which would provide the foundation for further research on production of medicinally important biocompounds.

The endemic and precious timber Pterocarpus santalinus L. f. (Red sanders) is a drought hardy tree species for conservation in peninsular India due to its high risk of illegal timber harvest. It is only found in Eastern Ghats of India, and has become threatened owing to overexploitation of its valuable timber. The development of genomic resources, particularly simple sequence repeat (SSR) markers, is essential for strict implementation of in situ conservation measures and application of DNA information based red sanders genetic resource management. However, a lack of genomic data and efficient molecular markers limit the study of its spatial and temporal population genetic structure, identification of diversity hotspots and tree improvement. The current study aims at comprehensive molecular characterization of red sanders and the somatic chromosome counts, flow cytometry and EST-SSR analyses. The results revealed that red sanders is diploid with 2n=20 and the 2C genome size was 0.7872 ± 0.0561pg for the first time in this species. A total of 3128 EST-SSRs were detected based on 25,854 de novo assembled unigenes from transcriptome data and primer sets designed for 1953 SSRs.
