Description
FIGURE 5. Somatic chromosomes at metaphase of Begonia. A. B. abbreviata (2n = 30: NTH 5917); B. B. calciphila (2n = 30: Peng et al. 20226); C. B. sphenantheroides 2n = 22: Peng et al. 20216); D. B. tamdaoensis (2n = 18: Peng et al. 16638); B', C', D', somatic chromosomes serially arranged by chromosome length and centromere position. Scale bars: B', C'= 2 μm; D' = 5 μm. Large arrows indicate a pair of the largest metacentric chromosomes with secondary constrictions (SC) at interstitial regions of the long arms; medium arrows indicate metacentric chromosomes with SC at distal regions of the long arms. Small arrows, large arrowheads and small arrowheads indicate metacentric chromosomes, subtelocentric chromosomes and telocentric chromosomes, respectively.
