Living gymnosperms comprise only a little more than 1000 species, but represent four of the
five main lineages of seed plants, including cycads, ginkgos, gnetophytes and conifers. This …

The conifers are a diverse and ancient group of seed plants of monophyletic origin that
arose more than 300 million years ago (Rothwell and Scheckler 1988). They are uniformly …

The family Pinaceae is made up mostly of diploid species (2 n= 24). Systematization of
karyotype analysis was developed to make comparison of intra-and interspecific karyotypes …

In higher eukaryotes, the 5S rRNA genes occur in tandem units and are arranged either
separately (S-type arrangement) or linked to other repeated genes, in most cases to rDNA …

Karyotypes of three Larix species (L. sibirica, L. gmelinii, and L. cajanderi) were analyzed
using fluorescence in situ hybridization (FISH) with 45S and 5S ribosomal RNA gene probes …

Twelve asparagus accessions collected from natural regions of Iran were analyzed by flow
cytometry to assess their ploidy level. These accessions belong to both cultivated and wild …

Every species has a unique karyotype, but certain genera have common karyptypes among
species. The markers (chromosome length and centromere position) used in traditional …

The present study describes the published karyotypes of 338 conifer taxa comprising of 302
species belonging to 59 genera of conifers. The somatic chromosome numbers range from …

Обсуждаются особенности изменчивости размера генома у видов хвойных в связи с
экстремальностью условий их произрастания, выражающиеся в вариабельности числа …

Transformation of the genome size in conifers growing in an extreme environment is
manifested in the variability of the number of chromosomes, content of nuclear DNA …
