Secale cereale Project
The GenomeZipper uses a novel approach that incorporates
chromosome sorting, second generation sequencing, array
hybridization and systematic exploitation of conserved
synteny with model grasses. It allows to assign 72% of the
estimated 31,008 rye genes to individual chromosomes. The
constructed 'zippers' integrate gene indices of rice,
sorghum and Brachypodium in a conserved synteny
model and assemble 22,426 rye genes in a putative linear
order. The GenomeZipper files provide a linear ordered,
information-rich scaffold of the rye genome.
Furthermore our results revealed a heterogeneous composition of the rye genome that could be the result of introgressive hybridization and/or several allopolyploidization events.
