The chromosome numbers of 75 species belonging to the family Araceae have been determined. The numbers for 53 species are reported for the first time. One number differs from previous reports (Aglaodorum), and one number is corrected (Phymatarum). Within 15 genera (Gymnostachys, Pothoidium, Alloschemone, Heteropsis, Holochlamys, Anaphyllopsis, Dracontioides, Pseudohydrosme, Montrichardia, Bucephalandra, Taccarum, Asterostigma, Gorgonidium, Spathantheum and Ulearum) the chromosome numbers have not previously been determined. The total number of genera cytologically investigated is now 99 (c. 94%). A great diversity in chromosome numbers as well as in chromosome size and constitution is found. The results are discussed in relation to the phylogeny and the previously published classifications of the family. A total list of chromosome numbers counted (>700 species) in the Araceae is presented (Appendix).

“…Only a few species are an exception to this, with x = 9 (3 species), x = 11 (2 species) and x = 13 (2 species), but without a special pattern (Darlington 1937, Noda 1964, Li and Shang 1989, Jafari et al 2014). However, the presence and the morphology of satellited chromosomes vary among the species or even among populations of the same taxon (Runemark 1970, Bentzer et al 1971, Mehra and Sachdeva 1976, Koul and Wafai 1980, Kamari 1984a, 1991a, 1996, Zaharof 1987, Kamari and Phitos 2006). In addition, secondary constrictions and supernumerary B-chromosomes are observed very often (La Cour 1978b, 1978c, Kamari 1984a, 1991a, 1991b, Zaharof 1987, 1989, Kamari and Phitos 2006).…”

Fritillaria Linnaeus, 1753 (Liliaceae) is a genus of geophytes, represented in Greece by 29 taxa. Most of the Greek species are endemic to the country and/or threatened. Although their classical cytotaxonomic studies have already been presented, no karyomorphometric analysis has ever been given. In the present study, the cytological results of Fritillaria montana Hoppe ex W.D.J. Koch, 1832 group, which includes Fritillaria epirotica Turrill ex Rix, 1975 and Fritillaria montana are statistically evaluated for the first time. Further indices about interchromosomal and intrachromosomal asymmetry are given. A new population of Fritillaria epirotica is also investigated, while for Fritillaria montana, a diploid individual was found in a known as triploid population. Paired t-tests and PCoA analysis have been applied to compare the two species.

“…The genus Spondias is poorly known cytogenetically. The only cytogenetic data available are the chromosome numbers (2 n = 32) of three species: S. pinnata (Mehra & Sachdeva, 1976; Sarkar et al ., 1982; Singhal & Gill, 1990), S. mombin (Guerra, 1986), and S. tuberosa (Pedrosa et al ., 1999). The aim of this work was to investigate the putative hybrid origin of Umbu‐cajá.…”

Karyotype differentiation among Spondias species and the putative hybrid Umbu-cajá (Anacardiaceae)

Spondias L. comprises at least nine Neotropical species, including the widely cultivated S. monbim and S. tuberosa. Umbu-cajá, a putative hybrid between these two species, is also grown. In this paper, the karyotypes of five Spondias species and Umbu-cajá were analysed for evidence of this hybridization. Chromosome banding with chromomycin A3 and the distribution of 5S and 45S rDNA sites were used to characterize the plants, also genomic in situ hybridization using nuclear DNA from both putative parents and the hybrid as probes. All material presented the same chromosome number (2n = 32) and morphology, but differed in the number and distribution of bands. Spondias monbim and S. tuberosa, the supposed relatives of Umbu-cajá, displayed similar banding patterns, with five to six chromosome pairs having terminal bands, whereas Umbu-cajá exhibited bands on both members of nine chromosome pairs. The three other species, S. venulosa, S. cytherea and S. purpurea, showed less closely related karyotypes, with bands in 12-18 chromosome pairs. In situ hybridization with 5S and 45S rDNA probes revealed one site of each probe per haploid chromosome complement in all material. However, in S. tuberosa, the location of 5S rDNA was different from the other species and found no counterpart in Umbu-cajá. Several tests with total DNA from S. mombin and S. tuberosa against metaphase chromosomes of Umbu-cajá failed to differentiate the individual genomes in the hybrid. From the chromosome banding and the distribution of rDNA sites, as well as from the genomic in situ hybridization, it seems clear that Umbu-cajá is related closely to S. monbim and S. tuberosa, but it is karyotypically homozygous and distinct from theses other species. Karyotypically, the three other investigated species were related less closely to Umbu-cajá.
