IAPT chromosome data 36

Abstract

AMARYLLIDACEAE. Habranthus cardenasianus Traub & I. S. Nelson, 2n = 24; Argentina, Salta, 10 Oct 2013, D 666 (MNES). The karyotypic formula consists in 12 metacentric (m) and 12 submetacentric (sm) chromosomes (Fig. 3). The genomic size is 213.73 µm. Fluorescent in situ hybridization showed the hybridization sites of the ribosomal DNA probes. The presence of active ribosomal genes (rDNA 18S / 26S) was located on the short arm of chromosomes 9 and 10 (m), on the long arm of chromosome 1 (m) and on the short arm of submetacentric chromosomes 23 and 24.
