Haemanthus katherinae

FIG. 2. Sister chromatid separation does not depend on the mitotic spindle. Light micrographs of mitosis in living flattened endosperm from Haemanthus katherinae BAK. treated with colchicine (c-mitosis). The micrographs were taken at 10 min intervals. Size bar, 10 /tm. Reprinted with permission from Mole-Bajer (1958). 

Epihaemanthamine (239) has been isolated along with haem-anthamine (318), which is the major alkaloid, from Haemanthus katherinae. Its identification was based on physical and chemical methods (48).

Figure 8. Multipole spindle apparatus fSlj. Microtubules are present but have functioned abnormally. Haemanthus katherinae liquid endosperm cells had been treated with 56 /xM propham. Magnification = 10,000X ...

Fig. 15. Drawing of chromosome motion to one pole and return toward the equator in a living mitotic cell of the blood lily Haemanthus katherinae). The numbers give the time in minutes at indicated positions. The drawings on the right show the chromosome configurations at various times during this motion but not the actual distance between successive positions kinetochore position is indicated by the small circles.

Fig. 16. Electron micrograph of a blood lily Haemanthus katherinae) chromosome in early mitotic prometaphase. Unipolar malorientation to a pole toward the left is suggested by the chromosomal microtubule arrangement at the two sister kinetochores ("ki/ The overall spindle axis is indicated by the arrow at the lower left side. The circle is a stain mark. XI 2,000. (From Bajer and Mole -Bajer. 1969. Chromosoma, 27 448-484.)...
