How cytomixis can form unreduced gametes in tobacco

Plant Systematics and Evolution, 2014
Cytomixis is migration of the nuclei between cells, widespread in various higher plant species. Most frequently, cytomixis takes place in microsporogenesis and is assumed to be a possible cause of unreduced gamete generation. In the present work the cytological mechanisms leading to a change in the cell chromosome number via cytomixis in tobacco ...

Cytomixis: Causes and Consequences as a Case Study in Vicia faba L.

2017
Broad bean (Vicia faba L.) is a member of the family Fabaceae which showed cytomixis during microsporogenesis. Cytomixis is proposed to be caused by genes, abnormal cell wall formation, action of chemicals, changes in the biochemical process, imbalanced and sterile genetic systems, persistence of male-sterile mutant genes, and frequent alterations in ...

Cytomixis in plants: causes, mechanisms and consequences

2011
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 ...

The invisible cytomixis: how a cytological phenomenon can be misinterpreted or totally overlooked

Planta
This review discusses how technical limitations of microscopic techniques as well as cognitive distortions of researchers hinder progress in the study of the phenomenon of cytomixis. The key element of any cytological work remains the interpretation of obtained data.

Discontinuities in the callose wall, intermeiocyte connections, and cytomixis in angiosperm meiocytes

Canadian Journal of Botany, 1974
Discontinuities, considered to be holes, were observed in the meiocyte callose wall of 25 dicotyledon and 5 monocotyledon taxa investigated by phase-contrast and Nomarski interference-contrast optics. With the exception of the Helianthus spp., where regular distribution was observed, the holes were confined to two to four discrete areas of the callose

[Cytomixis, its nature, significance and the cytological consequences].

TSitologiia i genetika, 2012
Cytomixis is the widespread natural process of intercellular interaction which is characteristic for vegetative and generative tissues in both normal and pathological conditions. The origin significance and genetic control cytomixis still remain not completely clear.
