CYTOLOGIA, 1988 Cytomixis has been observed in the pollen mother cells of Leucas aspera, two species of Mentha and two populations of Leonurus sibiricus. In Mentha piperita L. (2n=120), it has been noted to be of common occurrence as it occurs in almost all the stages of meiotic division.

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

Cytomixis and associated meiotic abnormalities affecting pollen fertility in Clematis orientalis
Biologia Plantarum, 2010 Present cytological investigations from the cold desert regions of Lahaul-Spiti and Kinnaur (India) record the first ever tetraploid (2n=32) chromosome count and cytomixis in Clematis orientalis L. var. acutifolia Hook. f. et Thoms.

Cytogenetic study and pollen viability of four populations of Trigonella [PDF]
Journal of Cell and Molecular Research, 2011 In the present paper, the cytogenetic study including meiotic chromosome number and behavior along with pollen viability were performed in 4 populations of Trigonella spruneriana Boiss. This is the first cytogenetic report of the taxon.

BioMed Research International, Volume 2014, Issue 1, 2014., 2014 A Lathyrus sativus L. mutant isolated in ethylmethane sulfonate‐treated M2 progeny of mother variety BioL‐212 and designated as rlfL-1 was characterized by inwardly rolled‐leaf and stem and bud fasciations. The mutant exhibited karyomorphological peculiarities in both mitosis and meiosis with origin of aneuploidy.
