“…Overall, the InDels data reveals that P. rubens is more closely related to P. mariana and P. abies than to P. glauca and P. sitchensis . This is consistent with known close relationships between P. rubens and P. mariana [ 28 , 29 , 30 , 34 , 35 ].…”

“…P. rubens has declined in the southern parts of its range, which has been associated with industrial air pollution [ 26 , 27 ]. In the northern range, introgressive hybridization occurs with sympatric P. mariana [ 28 , 29 , 30 ]. However, the extent of hybridization and evolutionary relationships between P. rubens and P. mariana are not very clear.…”

We have sequenced the chloroplast genome of red spruce (Picea rubens) for the first time using the single-end, short-reads (44 bp) Illumina sequences, assembled and functionally annotated it, and identified simple sequence repeats (SSRs). The contigs were assembled using SOAPdenovo2 following the retrieval of chloroplast genome sequences using the black spruce (Picea mariana) chloroplast genome as the reference. The assembled genome length was 122,115 bp (gaps included). Comparatively, the P. rubens chloroplast genome reported here may be considered a near-complete draft. Global genome alignment and phylogenetic analysis based on the whole chloroplast genome sequences of Picea rubens and 10 other Picea species revealed high sequence synteny and conservation among 11 Picea species and phylogenetic relationships consistent with their known classical interrelationships and published molecular phylogeny. The P. rubens chloroplast genome sequence showed the highest similarity with that of P. mariana and the lowest with that of P. sitchensis. We have annotated 107 genes including 69 protein-coding genes, 28 tRNAs, 4 rRNAs, few pseudogenes, identified 42 SSRs, and successfully designed primers for 26 SSRs. Mononucleotide A/T repeats were the most common followed by dinucleotide AT repeats. A similar pattern of microsatellite repeats occurrence was found in the chloroplast genomes of 11 Picea species.

“…vival (Fowler et al 1988;Morgenstern 1969a), and variation in growth rate (Fowler et al 1988;Morgenstern 19696;Morgenstern and Fowler 1969;Morgenstern et al 1981) and susceptibility to winter desiccation (Morgenstern 19696) are more closely related to degree of hybridization with black spruce than to inherent variation among red spruce populations. In fact, according to Gordon (1976), provenance differences in growth rate and susceptibility to winter desiccation were not significant when hybrid populations were excluded.…”

1994. Genetic diversity and population structure of red spruce (Picea rubens). Can. J. Bot. 72: [1778][1779][1780][1781][1782][1783][1784][1785][1786]. Allozyme variation at 36 loci was estimated for 19 populations of red spruce (Picea rubens Sarg.) from throughout its natural range. Average estimates of polymorphic loci (95% criterion), effective number of alleles per locus, and observed and expected heterozygosities are 23 %, 1.13, 7.47 % , and 7.89 %, respectively. Mean genetic distance among populations is 0.007, and 93% of the genetic diversity resides within red spruce populations. Comparisons with other species indicate that red spruce is less genetically variable than most other north-temperate woody plant species. Observed heterozygosity varied significantly among geographic regions, with northern cool-temperate populations having the highest mean observed heterozygosity, followed by central montane populations, then southern isolated populations with the lowest observed heterozygosity. Regional differences in genetic variability could be due to several factors, including migration from different glacial refugia, introgression of red spruce with more genetically variable black spruce in areas of sympatry in the north, and genetic drift followed by higher than expected levels of inbreeding in small isolated southern red spruce populations. Based on genetic distance, northern cool-temperate red spruce are more closely related to nonintrogressed red spruce than to nonintrogressed black spruce, suggesting that introgression is not a major factor contributing to greater genetic variability in the northern portion of the red spruce range. Relatively high genetic differentiation among populations, higher than expected levels of inbreeding, and evidence of reduced gene flow among populations suggest that low genetic variability evident in southern red spruce populations may be a result of genetic drift followed by inbreeding.Key words: Picea rubens, genetic diversity, isozymes, population genetic structure.

“…trees are monoecious and bear cones at a young age (Vincent 1965). Earliest seed-cone production has been noted at the age of six years (Morgenstern and Fowler 1969), and this precocity is one of the reasons why current improvement of this tree species in New Brunswick is based on seedling seed orchards.…”

Some Factors Influencing Cone Production on Young Black Spruce in New Brunswick

Ten young black spruce (Picea mariana [Mill.] B.S.P.) plantations in northern and central New Brunswick were examined to determine the influence of aspect, slope, tree age and tree height on pollen-cone and seed-cone production. It was found that a greater proportion of trees growing on southerly aspects produced pollen cones and seed cones than trees growing on northerly aspects. Trees growing on southerly aspects bore 2.5 and 5 times more seed cones and pollen cones, respectively, than trees growing on northerly aspects. Cone production on south-sloping sites was approximately double that on level sites. The number of seed cones was most significantly correlated with tree height. The number of pollen cones was most significantly correlated with number of seed cones.
