Abstract
The phenomenon of cytomixis as well as loss of chromosomes in the meiotic cells ofTrigonella foenum-graecum L. have been described. Because of cytomixis, at diakinesis and metaphase I, 18% of pollen mother cells (PMCs) showed chromosome numbers ranging from 3–28. Chromatin migration occurred after pairing through cytoplasmic bands connecting adjacent PMCs. In some PMCs the chromatin is transformed into thin whip-like structures and then migrated, while in others it breaks up into variously-sized bits before migration. It is suggested that this is a natural phenomenon and is under genetic control. The plant is partially fertile, hence the phenomenon may be of considerable evolutionary significance.
