Evolution of Plant B Chromosome Enriched Sequences
View through CrossRef
B chromosomes are supernumerary chromosomes which are found in addition to the normal standard chromosomes (A chromosomes). B chromosomes are well known to accumulate several types of repeats. Although the evolution of B chromosomes has been subject of numerous studies, the mechanisms of accumulation and evolution of repetitive sequences is not fully understood. Recently, new genomic approaches have shed light on the origin and accumulation of different classes of repetitive sequences in the process of B chromosome formation and evolution. Here we discuss the impact of repetitive sequences accumulation on the evolution of plant B chromosomes.

First non‐mosaic case of isopseudodicentric chromosome 18 (psu idic(18)(pter → q22.1::q22.1 → pter) Is associated with multiple congenital anomalies reminiscent of trisomy 18 and 18q− syndrome
AbstractIsopseudodicentric chromosome 18 is very rare and results in a combination of partial trisomy and partial monosomy of chromosome 18. We report here a hypotrophic newborn wi...
