RNA-seq and sRNA-seq analysis of maize W22 lines containing B chromosomes

ABSTRACT: The maize B chromosome is a non-essential chromosome and is not detrimental to plant development at low copy numbers. Nondisjunction of the maize B chromosome occurs at the second pollen mitosis. Maize lines containing B chromosomes are widely used in a variety of studies, such as gene dosage effect, centromere function and engineering of artificial chromosomes etc. An understanding of how the B chromosome affect gene expression is required for utilizing the B chromosome as tools for genetic studies and engineering. Therefore, we performed RNA-seq and small-RNA seq experiments on maize lines containing one through seven copies of B chromosomes to examine how gene expression responds to change of B copy numbers.
