Research over the past two decades has confirmed that noncoding RNAs (ncRNAs), which
are abundant in cells from yeast to vertebrates, are no longer “junk” transcripts but functional …

B chromosomes are supernumerary chromosomes which are often preferentially inherited,
deviating from usual Mendelian segregation. The balance between the so-called …

Supernumerary B chromosomes (Bs) are extra karyotype units in addition to A
chromosomes, and are found in some fungi and thousands of animals and plant species. Bs …

Background One of the biggest challenges in chromosome biology is to understand the
occurrence and complex genetics of the extra, non-essential karyotype elements, commonly …

Though hundreds to thousands of reports have described the distribution of B chromosomes
among diverse eukaryote groups, a comprehensive theory of their biological role has not yet …

For many years, parasitic B chromosomes have been considered genetically inert elements.
Here we show the presence of ten protein-coding genes in the B chromosome of the …

B chromosomes are supernumerary elements found in several groups of eukaryotes,
including fungi, plants, and animals. Typically, these chromosomes either originate from …

B chromosomes (Bs) are supernumerary elements found in many taxonomic groups. Most B
chromosomes are rich in heterochromatin and composed of abundant repetitive sequences …

A survey of new species with B chromosomes (Bs), based on a collection of 900
publications, gives an estimate of 406+ B species discovered since they were last surveyed …

B chromosomes are enigmatic heritable elements found in the genomes of numerous plant
and animal species. Contrary to their broad distribution, most B chromosomes are non …
