Comparative analyses of transcriptome during skeletal muscle development between pig breeds differing in muscle growth rate by deep-sequencing
Obese and lean pig show breed-specific traits in muscle growth and meat quality. However, the mechanisms underlying remains unclear. Here, we reported the first genome-wide muscle development research from embryonic to 6 months old between Lantang (obese) and Landrace (lean) using Solexa/Illumina's Genome Analyzer. We obtained 4.22±0.9×107 total reads per sample with approximately 5×106 distinct tags. Filtered adaptor tags, empty reads, low quality tags and tags of copy number =1, we obtained 3.84±0.9×107 clean total tags with 1.5±0.5×106 clean distinct tags. Overall design: 20 libraries of longissimus muscle samples were sequenced in Lantang and Landrace at days 35, 49, 63, 77, 91 prenatal and 2, 28, 90, 120, 180 postnatal days.
