“…Friebe et al (1987), basing on the C-banding pattern, renamed the seven pairs of H. villosa chromosomes as A-G, respectively, which corresponded to those 1Ha-7Ha of Sears. Zhong et al (1996), basing on the sequential C-banding-GISH analysis, showed a general similarity with the results of Friebe et al (1987).…”

“…Similarly Zhong et al (1996) found GISH after C-banding useful in identification of H. villosa chromosomes added to wheat. Multicolor fluorescent in situ hybridization revealed the 25S-5,8S-18S rRNA genes located on the short arm of 1V chromosome, and 5S rRNA genes on chromosome 5VS (Yuan et al 2000).…”

Dasypyrum villosum (L.) P. Candargy is discussed as a species commonly used in wheat improvement. Chromosomal localization of the potentially useful traits and chromosomal position of some morphological and isozyme markes are shown. The investigations using molecular RAPD, AFLP, SSR, RFLP markers and in situ (GISH, FISH) hybridization experiments on D. villosum itself and in wide hybrids with Triticum are summarized. The article also presents the information about designation of D. villosum chromosomes and the current knowledge on the phenomenon of two-coloured D. villosum caryopses.

Karyotype and C-banding patterns of mitotic chromosomes in Henrardia persica (Boiss.) C.E. Hubb

et al. 2002

Abstract·The C-banded karyotype of Henrardia persica (2n=2x=14), an annual self-pollinated grass species was studied in two natural populations using aceto-iron-hematoxilin staining and C-banding technique. It was revealed that the karyotype of this species is asymmetric and consists of 4 pairs of sub-acrocentric and 3 pairs of acrocentric chromosomes. One of chromosomes has a satellite located on the end of its long arm. Each chromosome having a unique C-banding pattern is easily recognizable.

“…Nevertheless, chromosome identification of cucumber was made, using a C-banding method, by Ramachandran and Seshadri in 1986, but as far as we know, no further C-banding has been pubUshed for cucumber. C-banding is the most widely applicable method and has been used not only to identify certain chromosomes (Zhong et al 1996), but also to make ideograms of cytologically based physical maps (Delaney et al 1995) in wheat. Attempts at C-banding in our own material are necessary, because polymorphism of C-banding patterns among different varieties or cultivars have been reported in many plants.…”

New C‐banding pattern for chromosome identification in cucumber (Cucumis sativus L.)

1998

A chromosome study of cucumber, C. sativus L., was performed using orcein and C-banding techniques. The diploid and tetraploid plants investigated here showed the somatic chromosome numbers 2n = 14 and 28, respectively. The haploid chromosome complement was composed of five metacentric and two submetacentric chromosomes. All C. sativus chromosomes had clearly visible C-bands, and each chromosome could be identified unequivocally after C-banding staining, with 13 C-bands appearing in the haploid complement. The haploid complement had a 44.9% ratio of total C-band length to total chromosome length. Chromosomes 1, 2, 4, 5 and 7 had stable C-bands. Three large, dark C-bands appeared at the proximal regions of chromosomes 1 and 2. Chromosome 1 had quite a large C-band and with a 68.4% ratio of C-band length to short arm length. Chromosome 2 also had quite a large C-band in the pericentromeric region with a 57.6% ratio of C-band length to the full length of this chromosome and possessed an elongated primary constriction in early metaphase. In prometaphase, chromosome 2 showed that the long arm was completely separated from the short arm. The number of secondary constrictions could not be clearly observed because these chromosomes are small and they could not be counted in every metaphase cell. However, six chromosomes seemed to have secondary constrictions in the diploid plants. Two silver-stained bands were observed at primary constrictions of two of the large chromosomes.
