Fundamentally different repetitive element composition of sex chromosomes in Rumex acetosa. Annals of Botany. 2021, 127(1), 33-47. ISSN 0305-7364. E-ISSN 1095-8290

Background and Aims: Dioecious species with well-established sex chromosomes are rare in the plant kingdom. Most sex chromosomes increase in size but no comprehensive analysis of the kind of sequences that drive this expansion has been presented. Here we analyse sex chromosome structure in common sorrel (Rumex acetosa), a dioecious plant with XY1Y2 sex determination, and we provide the first chromosome-specific repeatome analysis for a plant species possessing sex chromosomes.
