Non-Mendelian transmission of accessory chromosomes in fungi

Research on fungal accessory chromosomes, due to their small size, ease of sequencing, and epigenetic profiling, can complement the study of B chromosomes in deciphering factors that influence and regulate the non-Mendelian transmission of entire chromosomes.

Novel B-chromosome-specific transcriptionally active sequences are present throughout the maize B chromosome

The results suggest that the maize B chromosome indeed affects the expression of A-located genes and that a substantial amount of novel B-specific transcriptionally active sequences are present throughout the corn B chromosome.

It is revealed that avian GRCs are not exclusive to finches but are widely occurring in songbirds, a large clade consisting of over 4,000 species.

Are B chromosomes useful for crop improvement?

Selfish genetic elements

Though long dismissed as genetic curiosities, with little relevance for evolution, they are now recognized to affect a wide swath of biological processes, ranging from genome size and architecture to speciation.

Genomic Characterization of a B Chromosome in Lake Malawi Cichlid Fishes

This work identifies B chromosome sequences from several species of cichlid fish from Lake Malawi by examining the ratios of DNA sequence coverage in individuals with or without B chromosomes, and examines the efficiency of this method and compared results using both Illumina and PacBio sequence data.

Satellite DNAs Unveil Clues about the Ancestry and Composition of B Chromosomes in Three Grasshopper Species

The satDNAs shared among A and B chromosomes support the idea of putative intraspecific ancestry from small autosomes in the three species, i.e., pair S11 in R. brasiliensis, pair S9 in S. rubiginosa, and pair S10 in X. d.

Origin, Composition, and Structure of the Supernumerary B Chromosome of Drosophila melanogaster

The molecular characterization of D. melanogaster B chromosomes is the first step toward understanding how supernumerary chromosomes arise from essential chromosomes and what may be necessary for their stable inheritance.
