Induced cytomictic crosstalk behaviour among micro-meiocytes of Cyamopsis tetragonoloba (L.) Taub. (cluster bean): Reasons and repercussions [PDF]

open access: yesCaryologia, 2020
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 angiosperms from Northwestern Argentina

open access: yesBotany Letters, 2021
Cytomixis consists of the migration of chromatin and/or organelles between proximate cells through intercellular channels. Cytomixis has been detected in 10 taxa belonging to seven families from northwestern Argentina (NWA). The aim of this work was to report the presence of cytomixis in different species, genera and families of angiosperms from NWA ...

Cytomixis in Pollen Mother Cells of Medicago sativa L [PDF]

open access: yesJournal of Heredity, 2003
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.
