Plant Cytogenetics

The Cerrado (Brazil) plant cytogenetics database

Cerrado is a biodiversity hotspot that has lost ca. 50% of its original vegetation cover and hosts ca. 11,000 species belonging to 1,423 genera of phanerogams. For a fraction of those species some cytogenetic characteristics like chromosome numbers and C-value were available in databases, while other valuable information such as karyotype formula and banding patterns are missing. In order to in...

A historical and modern perspective on plant cytogenetics.

Plant cytogenetics has continued to flourish and make essential contributions to genomics projects by delineating marker order, defining contig gaps and revealing genome rearrangements. Here we review the field of plant cytogenetics from its conception through the eras of molecular biology and genomics. Significant advances in chromosome preparation, such as extended fiber-FISH, have greatly in...

Contributions to cytogenetics of Plectranthus barbatus Andr. (Lamiaceae): a medicinal plant

Accessions of Plectranthusbarbatus (Lamiaceae), a medicinal plant, were investigated using a cytogenetic approach and flow cytometry (FCM). Here, we describe for the first time details of the karyotype including chromosome morphology, physical mapping of GC rich bands (CMA3 banding), as well as the mapping of 45S and 5S rDNA sites. All accessions studied showed karyotypes with 2n = 30 small met...

Cytogenetics in Hematooncology

Cytogenetic methods are widely used during diagnosis in many types of hematological malignancies. Classical methods like karyotyping using GTG banding technique and molecular methods like fluorescent in situ hybridization (FISH) are still gold standard in clinics all over the world. According to WHO 2008 classification the cytogenetic analysis is the basic diagnostic tool during the diagnosis o...
