MITE Annotation and Landscape in 207 Plant Genomes Reveal Their Evolutionary Dynamics and Functional Roles

open access: yesMolecular Ecology Resources, Volume 25, Issue 8, November 2025.
ABSTRACT Miniature inverted‐repeat transposable elements (MITEs) are short, non‐autonomous class II transposable elements prevalent in eukaryotic genomes, contributing to various genomic and genic functions in plants. However, research on MITEs mainly targets a few species, limiting a comprehensive understanding and systematic comparison of MITEs in ...
