TL;DR: A tertiary structure model of the ATP-binding cassettes characteristic of this class of transport system is presented, based on similarities between the predicted secondary structures of members of this family and the previously determined structure of adenylate kinase.

TL;DR: A polymerase chain reaction (PCR)-based method which exploits this polymorphism for the generation of molecular markers in barley, which produces amplified fragments containing a Bare–1-like retrotransposon long terminal repeat (LTR) sequence at one end and a flanking host restriction site at the other.

TL;DR: It is postulate that the accumulation of such peptides may play a signaling role in the initiation of sporulation, and that the sporulation defect in opp mutants results from an inability to transport these peptides.

TL;DR: Phylogenetic analysis of sequences shows that the degree of sequence divergence in the retrotransposon populations between any pair of species is proportional to the evolutionary distance between those species, which implies that sequence divergence during vertical transmission of Ty1-copia group retro Transposons within plant lineages has been a major factor in the evolution ofTy1-Copia group Retrotransposons in higher plants.

TL;DR: Two assays based upon PCR detection of a polymorphic PDR1 retrotransposon insertion in Pisum sativum have been developed, which could in principle be applied to any transposable element in any plant species.
