Miniature inverted repeat transposable elements in the genome of sugar beet and their impact on gene expression.

ABSTRACT: Miniature inverted-repeat transposable elements (MITEs) are the most abundant group among class II mobile elements in plant genomes. They are frequently located in gene-rich regions, which may affect gene structure and expression, leading to functional diversity. Our research aimed to perform a comprehensive global annotation of MITEs in the sugar beet genome, which has been lacking to date. We also attempted to elucidate the association between the presence of MITE insertions and the regulation of gene expression. Analysis of the MITEs distribution in sugar beet revealed that MITEs cover about 3% of the genome, with the largest group comprising Stowaway-like elements. Approximately 60% of all identified MITEs were located within genic regions, indicating their potential impact on gene exp
