The breeding system and pollination ecology of Paeonia broteroi (Paeoniaceae), a selfcompatible, perennial herb, which produces few flowers (1-8) per season, are described in wo populations in mountains of southern Spain. Experimentally self-pollinated flowers yielded a significantly lower seed set (6-18%) than cross-pollinated flowers (23-29%), but the latter did not differ in seed set from op...

Tree peony is an important horticultural plant worldwide of great ornamental and medicinal value. Long terminal repeat retrotransposons (LTR-retrotransposons) are the major components of most plant genomes and can substantially impact the genome in many ways. It is therefore crucial to understand their sequence characteristics, genetic distribution and transcriptional activity; however, no info...
