Phenol-chroloform Library preparation was carried out as per manufacturer’s instructions (Illumina) using 10ng material. Samples were subsequently size-selected via gel migration and extraction, with average cut sizes at about 230 bp, including adapters. Sequencing was carried out on an Illumina Genome II Analyzer. The quality of libraries was checked with the Bioanalyser DNA High sensitivity and by Q-PCR. Sequencing was performed with the
