Different stages of chromosomes of Hymenocallis littoralis after orcein staining. A. Interphase nuclei; B. Prophase chromosomes; C. Metaphase chromosomes (Bar=10 μm).
Source publication
The present study offers the taxonomy, karyomorphology, and pollen-pistil interactions in the bulbous species Hymenocallis littoralis (Jacq.) Salisb. of the family Amaryllidaceae. The genus Hymenocallis is closely allied to Pancratium, however, differs from the later by filament, number and shape of ovule, and seed characteristics. Detailed descrip...

Context 1
... characteristics of Hymenocallis littoralis including the length, arm ratio, centromeric index, relative length and centromeric type of mitotic metaphase chromosomes are summarized in Table 2. In H. littoralis, orcein staining revealed homogenously stained interphase nuclei ( Fig. 2A), categorized as the "Diffused Type" according to Tanaka (1971). Similarly, the prophase chromosomes exhibited uniform staining along their length (Fig. 2B), classified as the "Continuous Type" based on classification of Tanaka (1971). Typically, specimens showing the "Diffused Type" in interphase nuclei, also display the "Continuous ...

... a homogeneous distribution of diffused heterochromatin at the interphase stage, which continues uniformly along the prophase chromosomes. This pattern aligns with the general characteristics of orcein staining in both interphase nuclei and prophase chromosomes. This study reveals that H. littoralis has a somatic chromosome number of 2n = 50 (Fig. 2C, Table ...
