Meiotic behaviour and morpho-phenological variation in cut stock (Matthiola incana L.) flower

open access: yesFolia 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.

Meiotic behavior of economically important plant species: the relationship between fertility and male sterility

open access: yesGenetics and Molecular Biology, 2000
Meiosis is an event of high evolutionary stability which culminates in a reduction of chromosome number. The normal and harmonious course of meiosis ensures gamete viability. The cytologic events of gametogenesis are controlled by a large number of genes

Recurrence of multiple meiotic abnormalities in maize genotypes from the same origin and their influence on productivity [PDF]

open access: yes, 2002
The frequency of meiotic abnormalities among single-, double- and three-way cross experimental hybrids and their parental inbred lines is studied. Among the sixteen inbred lines examined, fifteen originated from populations developed at the National ...

Cytomixis in pollen mother cells of alopecurus arundinaceus poir.

open access: yesCYTOLOGIA, 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.

Cytomixis in Pollen Mother Cells of Polygonum tomentosum Schrank.

open access: yesCYTOLOGIA, 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 ...
