“…Based on Levan et al (1964) method, the karyotype formula was determined to be 2m+8sm+6ac+8st for L. ledebourii and 2m+8ac+14st for L. longiflorum. This result is consistent with previous reports on L. longiflorum (Noda 1991, Lim et al 2001, Inceer et al 2002. Analysis of variance (Table 1) indicated that the long and short arm lengths and the arms ratio index were significantly different between the L. ledebourii and L. longiflorum.…”

SummaryThe karyological characteristics of two Lilium species were investigated by acetoferric-hematoxylin staining. Chromosome characteristics, including the number and length of the chromosomes, length of their long and short arms, length of the total set of chromosomes, the arm ratio index and relative lengths of chromosome, were measured based on averages for five different metaphase cells. Both species are diploid (2n=2x=24). The karyotype of Lilium ledebourii consisted of 1 pair of metacentric, 4 pairs of submetacentric, 3 pairs of acrocentric and 4 pairs of subtelocentric chromosomes. The karyotype of Lilium longiflorum was comprised of 1 pair of metacentric, 4 pairs of acrocentric and 7 pairs of subtelocentric chromosomes. Chromosomes 5 and 7 in Lilium ledebourii and chromosomes 6 in Lilium longiflorum had a satellite. Karyotypes were classified as 3A by Stebbins classification.

Such changes produced various chromosome features like amount and location of secondary constrictions or intercalary satellites were found useful in taxonomic researches in our study.…”

Noda (1991) suggested the major differences among species of the genus Lilium corresponded to the number and position of secondary constrictions (SCs) and the activity of nuclear organization regions (NORs). He concluding about the type of speciation in the genus Lilium, which included long-term accumulation of numerous small structural chromosome changes.…”

In this paper, karyotype data of the tribe Lilieae in China were analyzed and been superimposed onto a phylogenetic framework constructed by the internal transcribed spacer to investigate the karyotype evolution. Ten parameters for analyzing karyotype asymmetry were assessed and karyotypic idiogram of five genera of Lilieae were illustrated. The results showed that, the relationship of genera in Lilieae that inferred from Maximum Parsimony criteria and Bayesian Inference were congruent with previous studies, which focused on higher level of Liliales. The karyotype showed distinctive among genera, mainly expressed on the location and amount of secondary constrictions and intercalary satellites: the genus Notholirion have neither of them, and the genera Cardiocrinum and Fritillaria have the secondary constriction alone; the genera Lilium and Nomocharis showed both features, and the distribute pattern of the intercalary satellites showed similarity among related clades. The asymmetry that assessed by several methods indicated that the evolution trend of Lilieae did not follow a single direction, but different in each genus. On the sectional level of the genus Lilium (including Nomocharis) the karyotype evolution included three major periods. Combining the chromosomal structure variations and karyotype asymmetry, the chromosome diversity and evolution in Lilieae were quite clear in the light of molecular inference.

“…Lilium species have attracted much attention in cytological respect since they have almost the biggest genome size in the plant kingdom (Peruzzi et al 2009). Many studies have been conducted all over the world (Stewart 1947, Smyth et al 1989, Noda 1991, Siljak‐Yakovlev et al 2003, Muratović et al 2005, 2010a). Noda (1991) suggested that the major differences among species of the genus Lilium correspond to the number and position of secondary constrictions (SCs) and the activity of nuclear organization regions (NORs).…”

Fifty-two populations representing thirty-two taxa of Lilium L. from China are karyologically analyzed. The results showed that all populations have the same basic chromosome number x012, and all species are diploid except Lilium tigrinum, which is triploid with 2n036. In addition, one population of L. sulphureum is aneuploid with 2n023. The karyotype evolution in the genus Lilium is mainly in terms of alterations of the fine structure of the chromosomes, not in ploidy or basic chromosome number variation. When combining previous studies and our results, we consider the major driving forces for evolution of Lilium to be an increase in karyotypic asymmetry, and unequal translocation and formation of secondary constrictions. The existence of intercalary satellites on the two largest pairs of chromosomes is correlated with the geographic distribution pattern of Lilium across the world. The Hengduan Mountains is a modern diversity and differentiation center of Lilium and it also could be the center of origin for this genus. In addition, some taxonomic conclusions were verified on the subgenus level. Among the species investigated, the chromosome number and karyotypes of 13 taxa were documented for the first time.
