Abstract
AbstractThis chapter describes supernumerary or accessory chromosomes (B-chromosomes) in several grasses focusing on those in species of the sub-tribe Triticineae of the tribe Triticeae. It refers to their origin, molecular characterization, preferential transmission (accumulation mechanism), effect on morphology, fitness, and chromosomal pairing in species and hybrids, and their transcriptional activity.
