A cyclophilin gene marker confirming geographical differentiation of Norway spruce populations and indicating viability response on excess soil‐born salinity

Abstract: A newly identified cyclophilin-encoding cDNA clone was used to design a codominant inherited EST-PCR marker in Norway spruce. The study of the current minor polymorphism revealed a geographically structured differentiation pattern across 17 test populations, showing a slight clinal variation south-north through Europe. Based on the frequency of alleles, isolation-by-distance analysis and the Ewens-Watterson test, we conclude that a selectively neutral random-drift mutation recently occurred within the Alpine p… Show more

“…Compared with EST-SSRs, the development of genomic-SSRs is very expensive, labor intensive and timing consuming. Genomic-SSRs have uncertain linkage to the transcribed regions of the genome, while EST-SSRs are potentially linked with particular transcriptional regions that contribute to agronomic phenotypes [23,24]. In addition, EST-SSRs have high transferability, because sequences containing EST-SSRs are more conserved than sequences containing genomic-SSRs and can be utilized in other related species [25].…”

“…EST-SSRs generally are more conserved within and across related species and show higher transferability because more variable intron or intergenic sequences are absent from ESTs [11]. Additionally, it is more likely that EST-SSRs are tightly linked to specific gene functions and perhaps some even play a direct role in controlling important agronomic traits [12]. Therefore, EST-SSRs are good tools to facilitate marker-assisted selection (MAS) for breeding.…”

“…Microsatellites or SSRs are defined as highly variable DNA sequences composed of tandem repeats of 1–6 nucleotides with co-dominant inheritance which have become the markers of choice for a variety of applications including characterization and certification of plant materials, identification of varieties with agronomic potential, genetic mapping, assistance in plant-breeding programs, among others [15], [16], [17], [18], [19]. However, no SSR markers specific for P. peruviana have been developed.…”

“…The de novo identification of simple sequence repeats has usually involved large-scale sequencing of genomic, SSR-enriched genomic or EST libraries, which are expensive, laborious and time-consuming. Next generation sequencing technologies have enabled rapid identification of SSR loci derived from ESTs which can be identified in any emergent species [17], [19], [21].…”
