Chromosome Numbers and Karyotypes of Representatives of Caryophyllaceae from Korea

Abstract

Somatic chromosome numbers were determined for 15 taxa belonging to six genera of Caryophyllaceae in South Korea, Pseudostellaria (three species), Stellaria (three species), Dianthus (one species), Gypsophila (one species), Lychnis (two species) and Silene (five species), and were compared with previously reported chromosome numbers for each genus and species. This is the first report of chromosome numbers for two species, Silene koreana (2n=24), and S. seoulensis (2n= 24). Furthermore, a karyotype analysis of five Silene species indicated that the basic number were all x=12, with the following karyotypic formulas: S. aprica var. oldhamiana (2n=4x=48=48m), S. jenisseensis (2n=2x=24=20m+4sm), S. koreana (2n=2x=24=16m+8sm), S. seoulensis [2n=2x=24+ I=20m (4sat)+4sm], and S. takesimensis [2n=2x=24=20m+4sm (1sat)]. These were the first karyotype analyses for the examined taxa, except S. aprica var. oldhamiana. S. seoulensis had the most asymmetrical karyotype among these species.

Effective Chromosomal Preparation Protocol for the Dioecious Plant <i>Silene latifolia</i>

“…Chromosome specimen preparation is fundamental for several aspects of cytology, including karyotyping, fluorescence in situ hybridization (FISH), and chromosome microdissection (Bhowmick Biplab and Jha 2019, Kono et al 2019, Dash Chandan et al 2020, Nam et al 2020, Saensouk and Saensouk 2020, Samaropoulou et al 2020, Santra et al 2020, Shafiee et al 2020, Sheng et al 2020, Suto et al 2020, Widarmi et al 2020, Wang et al 2021. These techniques revealed differences in chromosome architecture between species, chromosomal abnormalities associated with diseases, and the roles of chromosomes in sex determination.…”
