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.

Temperature Sensitive Cytomixis in Helicanthes elastica (Desr.) Dans. (Loranthaceae).
CYTOLOGIA, 1993 Spontaneous occurrence of cytomixis in PMCs of H. elastica was noticed in high atmospheric temperature. The chromatin undergoes a temporary process of agglutination before migration. Cytomixis is found to have a direct correlation with other meiotic irregularities and sterility. The origin and evolutionary significance of the process is discussed.

The Scientific World Journal, Volume 2012, Issue 1, 2012., 2012 Two accessions were studied for male meiosis in Ranunculus laetus from the cold regions of Northwest Himalayas. One accession showed the presence of 14 bivalents at diakinesis and regular segregation of bivalents at anaphase I which lead to normal tetrad formation with four n microspores and consequently n pollen grains and 100% pollen fertility ...

Cytomixis and its role in the regulation of plant fertility [PDF]
Russian Journal of Developmental Biology, 2013 UV and gamma irradiation of barley seedlings induces an increase in the number of various pathologies in the male reproductive system of plants. The majority of cytological abnormalities are rather nonspecific. The main type of the observed pathologies of microsporogenesis is cytomixis, whose activation correlates with a callose hypersecretion in ...

Characteristics of cytomixis in the pollen mother cells of green manure crop Sesbania cannabina [PDF]
Journal of Central European Agriculture, 2013 Cytomixis has been reported in many plant species, but there is no published report in Sesbania cannabina spp. The cytological stability of any plant is an important consideration in view of its extensive use in genetics and plant breeding programmes ...

Cytomixis in Vigna glaberscens TTK1 (wild).
CYTOLOGIA, 1988 Cytogenetical studies in Vigna glaberscens TTK1 revealed twenty two and fourty four as haploid and diploid chromosome numbers respectively. Spontaneous occurrence of cytomixis is due to the transfer of chromatin material from one pollen mother cell to other through connecting channel has been noted. Pollen mother cells with reduced chromosome number (n=
