“…H. rhamnoides has high ecological, medicinal and economic value (Bal et al, 2011; Dhyani et al, 2011; Jadhav, 2014; Kortesniemi et al., 2017; Suryakumar & Gupta, 2011), and thus has attracted an abundance of research on breeding, systematics, biochemistry and genetics (Bartish, 2016). Previous studies have developed SSR markers for sea buckthorn from enriched genomic libraries (Islam et al, 2015; Wang et al., 2008) and transcriptome sequences (Jain et al., 2014; Li et al, 2020; Li, Ruan, et al, 2017; Li, Zeng, et al., 2017; Xie et al., 2017). Few has discussed the usage of SSR markers on sea buckthorn phylogenetic analysis and/or breeding programme.…”

Simple sequence repeat (SSR) markers play an important role in genetic and molecular breeding programs, especially for non‐model species. We identified SSRs from expressed sequence tags (EST‐SSRs) and whole genome sequences (gSSRs), by analysing the transcriptome and genome of the Mongolian sea buckthorn (Hippophae rhamnoides subsp. mongolica) cultivar ‘Sunny’. Using the same number of loci, EST‐SSRs showed higher transferability to Hippophae than gSSRs, and phylogenetic trees based on EST‐SSRs demonstrated higher resolution for classifying Hippophae species and subspecies into clades, possibly due to high conservatism and/or existence of adaptive divergence between species/subspecies in coding sequence regions. In contrast, parentage analyses showed that gSSRs were more effective at resolving parentage than EST‐SSRs due to higher level of polymorphism in gSSRs. The markers developed in this study can be used in the identification and pedigree reconstruction of species/subspecies of sea buckthorn, while their usage in clarifying phylogenetic relationship among species remains to be discussed. The comparison between EST‐SSRs and gSSRs would provide insight into the trade‐off between differentiation and polymorphism in marker selection for breeding programs.

“…The conflicting phylogenetic diagnoses of nuclear and chloroplast sequences are common in plants (Degna & Rosenberg, 2009 ). The adaptive radiation caused by heterostyly, polyploidization, and natural hybridization, or gene introgression might complicate the phylogenetic relationships under Primula (De Vos et al, 2014 ; Guggisberg et al, 2009 ; Ma et al, 2014 ; Xie, Zhao, et al, 2017 ; Xie, Zhu, et al, 2017 ). Furthermore, chloroplast capture through hybridization may occur in these sections, which has been documented in plants and the genus Primula (Casazza et al, 2012 ; Yi et al, 2015 ).…”

“…Moreover, many key diagnostic traits, such as the shape of calyx, are slightly different and nonquantitative. The frequent natural hybridization and gene introgression also confuse species boundaries in this genus (De Vos et al, 2014 ; Guggisberg et al, 2009 ; Ma et al, 2014 ; Xie, Zhao, et al, 2017 ; Xie, Zhu, et al, 2017 ). Although an increasing number of phylogenetic constructions have been carried out previously and have greatly advanced our understanding of the evolution of Primula , the phylogenetic relationships within the genus Primula species have remained incompletely resolved.…”

“…On the one hand, the conflicting phylogenetic diagnoses of nuclear and chloroplast sequences are common in plants [81]. On the other hand, the adaptive radiation caused by heterostyly, polyploidization and natural hybridization, or gene introgression might complicate the phylogenetic relationships under Primula [20][21][22][23][24]. This would explain why quite a few sections inPrimula didn't belong to monophyletic group according to morphological characters.…”

Primula, well known for its heterostyly, is the largest genus in the family Primulaceae with more than 500 species. The considerable species number has introduced a huge challenge for taxonomy. Although several phylogenetic constructions have been carried out thoroughly, the relationships between Primula species were remained incompletely understood, especially for the relationship among sections within Chinese species. P. wilsonii Dunn is a PSESP (plant species with extremely small populations) with very limited genetic information to explore its endangered mechanism and conservation. In this study, we sequenced and assembled the complete chloroplast genomes of P. wilsonii using Illumina sequencing and compared its genomic sequences with those of four related Primula species. The chloroplast genomes of Primula species were similar in the basic structure, gene order and GC content. The detected 38 SSRs loci and 17 hyper-variable regions had many similarities in P. wilsonii, P. anisodora, P. miyabeana and P. poissonii, but showed a significant difference compared with those in P. secundiflora. Slight variations were observed among Primula chloroplast genomes, in consideration of the relatively stable patterns of IR contraction and expansion. Phylogenetic analysis based on chloroplast genomes confirmed three major clades in Chinese Primula, but the infrageneric sections were not in accordance with morphological traits. The P. poissonii complex was confirmed here and P. anisodora was the species that was most closely related to P. wilsonii. Overall, the chloroplast genome sequences provided useful genetic and evolutionary information for phylogeny, population genetics and conservation studies on Chinese Primula species.
