Cytomolecular characterization and origin of de novo formed maize B chromosome variants.

Chromosome research : an international journal on the molecular, supramolecular and evolutionary aspects of chromosome biology - 1 May 2016

Abstract excerpt

B chromosomes are dispensable elements that occur in many species, including maize. The maize B chromosome is acrocentric and highly heterochromatic and undergoes nondisjunction during the second pollen mitosis. In this study, we determined the genetic behavior and organization of two naturally occurring B chromosome variants (designated B(ta) and B(tb)). The morphology and genetic behavior of the B(ta)...
