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

CYTOGENETIC STUDY OF GAMMA IRRADIATED LINES OF COTTON (GOSSYPIUM HIRSUTUM L.) [PDF]
A cytogenetic study was performed on M4 generation of gamma irradiated lines of Shirpan cultivar of tetraploid cotton (Gossypium hirsutum L.). A significant difference was observed in cytogenetical characteristics such as the number and type of ...

Cytomixis in plants: causes, mechanisms and consequences
A migração de organelas, produtos gênicos e material genético entre meiócitos por meio de conexões citoplasmáticas ou canais citomíticos é definida como citomixia. Esse fenômeno tem sido relatado em Leguminosae, Brassicaceae, Poaceae, Apocynaceae, Liliaceae, Rutaceae, entre outras famílias, sendo mais comumente observado entre células mãe dos grãos de ...

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

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
