Meiotic behaviour and morpho-phenological variation in cut stock (Matthiola incana L.) flower
Folia Horticulturae, 2017 Morpho-phenological and meiotic studies were performed in twelve cultivars of Matthiola incana. All of the cultivars were diploid (2n = 2x = 14) with basic chromosome number x = 7.

Cytomixis in pollen mother cells of alopecurus arundinaceus poir.
CYTOLOGIA, 1990 Cytomixis has been observed for the first time in a tetraploid Alopecurus arundinaceus (2n=4x=28). This phenomenon has resulted in the formation of hypo- and hyperploid cells which, however, failed to reach later stages of meiosis.

CHROMATIN EXTRUSION AND CYTOMIXIS IN POLLEN MOTHER CELLS OF HORDEUM
Hereditas, 2010 HROMATIN extrusion and cytomisis or the transfer of nuclear C material from one cell to an adjacent cell has been reported in many plant genera for a number of years (SARVELLA, 1958). During cytological analysis of a number of barley mutants induced by X-rays and neutrons many pollen mother cells were found with a clear evidence of chromatin extrusion ...

Cytomixis in Pollen Mother Cells of Polygonum tomentosum Schrank.
CYTOLOGIA, 1995 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 ...
