Cytomixis in the Microsporogenesis of Vicia faba L. (Fabaceae)
CYTOLOGIA, 2004 Cytomixis has been observed in pollen mother cells of Vicia faba. Of all eight sites plant materials were collected and investigated, cytomixis has been noted in six. Four of these sites recorded high percentage of cytomixis, where the two other sites show low concentration of this phenomenon.Cytomixis was observed to occur in forms of cytoplasmic ...

Temperature Sensitive Cytomixis in Helicanthes elastica (Desr.) Dans. (Loranthaceae).
CYTOLOGIA, 1993 Spontaneous occurrence of cytomixis in PMCs of H. elastica was noticed in high atmospheric temperature. The chromatin undergoes a temporary process of agglutination before migration. Cytomixis is found to have a direct correlation with other meiotic irregularities and sterility. The origin and evolutionary significance of the process is discussed.

Cytomixis in Pollen Mother Cells of Salvia miltiorrhiza [PDF]
Caryologia, 2009 Abstract Cytomixis has been described in many plant species, but not in Salvia miltiorrhiza Bunge, a well-known Chinese herb. The present study reports spontaneous cytomixis during microsporogenesis in S. miltiorrhiza (2n = 16) for the first time. Cytomixis frequently occurred in early prophase I but very rarely in meiosis II.
