dc.descriptionThe product of meiosis is a callose-enclosed tetrad of haploid microspores resulted from partitioning of the cytoplasm, a process called as cytokinesis. Cytokinesis requires both the tubulin and the actin cytoskeleton at various stages in its initiation and execution. In many species, abnormalities related to spindle and cytokinesis affected the cellularization process compromising the meiosis products and pollen fertility. Despite its economic importance for forage, the genus Brachiaria is poorly known on their cytological basis. Cytogenetic studies carried out in the tetraploid accession D62 of Brachiaria decumbens (2n=4x=36) revealed an unusual pattern of microsporogenesis.
