Phytochemical attributes of endemic endangered primrose (Primula heterochroma Stapf.) accessions grown in Iran.

ABSTRACT: Primula heterochroma is indigenous to Caspian coast forests in the north of Iran. Total phenols, total flavnoids, total carotenoids and antioxidant capacity of 50 P. heterochroma accessions were investigated. The highest total phenol (1272.31 mg GA equivalent/100 g fresh weight) and total flavonoids (615 mg catechin/100 g fresh weight) were observed in G5 accession from Saravan. The highest antioxidant activity was observed in G14 accession (73.03 %) from Kacha, followed by G2 accession (69.75 %) and G5 accession (66.84 %) from Saravan. The results of HPLC analysis showed that quercetin-3-glucoside was the major phenolic compound widely found in these accessions followed by chlorogenic acid. There was a linear relationship between the antioxidant capacities and the total phenols and total flavonoid. Inversely, there was no statistically significant correlation between total carotenoid and antioxidant activity. Based on the path coefficient analysis, the maximum direct effect on antioxidant was observed in total phenols (0.908). In addition, the cluster analysis based on Euclidean distance with Unweighted pair-group method using arithmetic average (UPGMA) method separated the accessions into four main groups. Our results supported that Iranian wild primrose accessions possess valuable antioxidant properties for therapeutic and potential medicinal use.

Project description:BackgroundPrimula species are important early spring garden plants with a centre of diversity and speciation in the East Himalaya-Hengduan Mountains in Western China. Studies on population genetics, speciation and phylogeny of Primula have been impeded by a lack of genomic resources. In the present study, we sequenced the transcriptomes of two closely related primrose species, Primula poissonii and Primula wilsonii, using short reads on the Illumina Genome Analyzer platform.ResultsWe obtained 55,284 and 55,011 contigs with N50 values of 938 and 1,085 for P. poissonii and P. wilsonii, respectively, and 6,654 pairs of putative orthologs were identified between the two species. Estimations of non-synonymous/synonymous substitution rate ratios for these orthologs indicated that 877 of the pairs may be under positive selection (Ka/Ks > 0.5), and functional enrichment analysis revealed that significant proportions of the orthologs were in the categories DNA repair, stress resistance, which may provide some hints as to how the two closely related Primula species adapted differentially to extreme environments, such as habitats characterized by aridity, high altitude and high levels of ionizing radiation. It was possible for the first time to estimate the divergence time between the radiated species pair, P. poissonii and P. wilsonii; this was found to be approximately 0.90 ± 0.57 Mya, which falls between the Donau and Gunz glaciation in the Middle Pleistocene. Primers based on 54 pairs of orthologous SSR-containing sequences between the two Primula species were designed and verified. About half of these pairs successfully amplified for both species. Of the 959 single copy nuclear genes shared by four model plants (known as APVO genes), 111 single copy nuclear genes were verified as being present in both Primula species and exon-anchored and intron-spanned primers were designed for use.ConclusionWe characterized the transcriptomes for the two Primula species, and produced an unprecedented amount of genomic resources for these important garden plants. Evolutionary analysis of these two Primula species not only revealed a more precise divergence time, but also provided some novel insights into how differential adaptations occurred in extreme habitats. Furthermore, we developed two sets of genetic markers, single copy nuclear genes and nuclear microsatellites (EST-SSR). Both these sets of markers will facilitate studies on the genetic improvement, population genetics and phylogenetics of this rapidly adapting taxon.
