Cytomixis in Pollen Mother Cells of Polygonum tomentosum Schrank.
Cytomixis, representing the migration of chromatic material from one cell to another, was observed in PMC's of Polygonum tomentosum Schrank. Cytomixis was observed at all stages of meiosis, but became less frequent in the later stages of meiosis. Direct nuclear fusion and cytoplasmic connections between cells were noted, so that a series of PMC's were ...

Cytomictic behaviour of chromosomes among pollen mother cells was observed in mutagenic studies in cluster bean (Cyamopsis tetragonoloba (L.) Taub.). The study of pollen mother cells (PMC) revealed various chromosomal aberrations among which cytomixis ...

Cytomixis in Pollen Mother Cells of Medicago sativa L [PDF]
Cytomixis (i.e., chromatin migration between meiocytes) has been detected in many plant species, but not in Medicago sativa spp. In the present study we report the identification of a few cytomictic alfalfa plants. Those plants, the "mother plants," were selfed and crossed with a normal control plant.

Cytomixis and associated meiotic abnormalities affecting pollen fertility in Clematis orientalis
Present cytological investigations from the cold desert regions of Lahaul-Spiti and Kinnaur (India) record the first ever tetraploid (2n=32) chromosome count and cytomixis in Clematis orientalis L. var. acutifolia Hook. f. et Thoms.

A Lathyrus sativus L. mutant isolated in ethylmethane sulfonate‐treated M2 progeny of mother variety BioL‐212 and designated as rlfL-1 was characterized by inwardly rolled‐leaf and stem and bud fasciations. The mutant exhibited karyomorphological peculiarities in both mitosis and meiosis with origin of aneuploidy.

Cytomixis in pollen mother cells of Papaver dubium L.
Cytomixis was recorded during microsporogenesis in Papaver dubium L., a member of the family Papaveraceae. The phenomenon was observed in all the stages of meiosis. Further, it was found that not only the frequency of cytomixis but the amount of chromatin transferred reduced with the advancement of meiosis. The pollen fertility was found to be affected
