Induced syncyte formation via cytomixis in Trachyspermum ammi (L.) Sprague (Apiaceae) [PDF]

open access: goldCaryologia (Firenze), 2018
Cytomixis is a remarkable cytological event which has been presumed to be a prime facilitator of the origin of infraspecific polyploidy. The phenomenon of intercellular chromatin transmigration through cytomictic channels was reported during meiotic ...

Analysis of cytoskeleton in the cells involved in cytomixis: the migrated chromatin displays an MT-organizing activity and can interact with the spindle [PDF]

open access: bronzeBiologia, 2019
The structure of cytoskeleton in the tobacco male meiocytes involved in the migration of nuclei between cells (cytomixis) is studied. The tubulin and actin components of cytoskeleton are examined using specific antibodies and phalloidin.

Meiotic abnormalities affect genetic constitution and pollen viability in dicots from Indian cold deserts [PDF]

open access: yesBMC Plant Biology, 2019
Background Meiotic abnormalities lead to morphological and genetic variations which caused not only to evolution but also intraspecific reproductive barriers.

Induction of phenotypic diversity in mutagenized population of lentil (Lens culinaris Medik) by using heavy metal [PDF]

open access: yesHeliyon, 2019
Pulse breeding has been performed in the past by utilizing the genetic variability using conventional method. At the present time, these techniques are insufficient for producing new cultivars to fulfill globally increased food demand. In this situation,
