B chromosomes are extra chromosomes to the standard complement that occur in many
organisms. They can originate in a number of ways including derivation from autosomes and …

B chromosomes are dispensable elements that do not recombine with the A chromosomes
of the regular complement and that follow their own evolutionary track. In some cases, they …

Publisher Summary Chromosomes are vehicles that facilitate the organized and fair
transmission of cooperative genes during cell division. The Mendelian segregation law, for …

Abstract Background Supernumerary B chromosomes (Bs) are a major source of
intraspecific variation in nuclear DNA amounts in numerous species of plants. They favour …

B chromosomes, also known as supernumerary chromosomes, are dispensable elements in
the genome of many plants, animals, and fungi. Many B chromosomes have evolved one or …

The most distinctive region of the rye B chromosome is a subtelomeric domain that contains
an exceptional concentration of B-chromosome-specific sequences. At metaphase this …

The genomes of many plants, animals, and fungi frequently comprise dispensable B
chromosomes that rely upon various chromosomal drive mechanisms to counteract the …

B chromosomes (Bs) can be described as 'passengers in the genome', a term that has been
used for the repetitive DNA which comprises the bulk of the genome in large genome …

This work reviews recent advances providing insights on the origin and evolution of B
chromosomes (Bs) in representative plant species. Brachyome dichromosomatica has large …

Triticale (× Triticosecale Wittm) is an economically important crop for fodder and biomass
production. To facilitate the identification of markers for agronomically important traits and for …
