B chromosome contains active genes and impacts the transcription of A chromosomes in maize (Zea mays L.).

BMC plant biology - 16 Apr 2016

Huang Wei, Du Yan, Zhao Xin, Jin Weiwei

Abstract excerpt

BACKGROUND: The dispensable maize (Zea mays L.) B chromosome is highly heterochromatic and widely believed to be devoid of functional genes. Although low-copy B chromosome causes no obvious phenotype variation, its existence might influence A genome gene expression. Previous studies suggested that B chromosomes are evolved from standard chromosomes; therefore, they might contain genic regions showing homology...
