Characterization of microsatellites for the endangered Ruta oreojasme (Rutaceae) and cross-amplification in related species.

ABSTRACT: UNLABELLED: PREMISE OF THE STUDY:Ruta oreojasme is an endangered species endemic to Gran Canaria (Canary Islands, Spain), where it occurs in small populations with disjunct distribution. Nothing is known about the genetic structure of these populations. • METHODS AND RESULTS:Using a microsatellite-enriched library method, 10 microsatellite markers have been developed from R. oreojasme, all of which showed polymorphism. The transferability of the 10 markers was tested in two other Canarian endemic species, R. microcarpa and R. pinnata, as well as in the widespread species R. montana. • CONCLUSIONS:Our results demonstrate the value of these newly developed microsatellite markers to investigate the genetic structure in R. oreojasme and show their potential applicability for population genetic studies in other Ruta species.

Project description:Amaranth (Amaranthus spp.) belonging to Amaranthaceae, is known as "the crop of the future" because of its incredible nutritional quality. Amaranthus spp. (> 70) have a huge diversity in terms of their plant morphology, production and nutritional quality; however, these species are not well characterized at molecular level due to unavailability of robust and reproducible molecular markers, which is essential for crop improvement programs. In the present study, 13,051 genome-wide microsatellite motifs were identified and subsequently utilized for marker development using A. hypochondriacus (L.) genome (JPXE01.1). Out of those, 1538 motifs were found with flanking sequences suitable for primer designing. Among designed primers, 225 were utilized for validation of which 119 (52.89%) primers were amplified. Cross-species transferability and evolutionary relatedness among ten species of Amaranthus (A. hypochondriacus, A. caudatus, A. retroflexus, A. cruentus, A. tricolor, A. lividus, A. hybridus, A. viridis, A. edulis, and A. dubius) were also studied using 45 microsatellite motifs. The maximum (86.67%) and minimum (28.89%) cross-species transferability were observed in A. caudatus and A. dubius, respectively, that indicated high variability present across the Amaranthus spp. Total 97 alleles were detected among 10 species of Amaranthus. The averages of major allele frequency, gene diversity, heterozygosity and PIC were 0.733, 0.347, 0.06, and 0.291, respectively. Nei's genetic dissimilarity coefficients ranged from 0.0625 (between A. tricolor and A. hybridus) to 0.7918 (between A. viridis and A. lividus). The phylogenetic tree grouped ten species into three major clusters. Genome-wide development of microsatellite markers and their transferability revealed relationships among amaranth species which ultimately can be useful for species identification, DNA fingerprinting, and QTLs/gene(s) identification.Supplementary informationThe online version contains supplementary material available at 10.1007/s13205-021-02930-5.
