pig transcriptome

The placenta has shown morphological and functional adaption in Meishan and Yorkshire pig breeds during late gestation. While the vast difference of uterine capacity and conceptus genotype between Western and Chinese pig breeds affects the pattern of placental development. Whether the placenta within Chinese pig breed also has similar adaptive changes is still unknown. So, we measured the weight and area of 80 Chinese indigenous Diannan small-ear pig placentas and further selected 6 placentas from extremely high and low litter size groups (HL and LL) for deep RNA-sequencing to detect the molecular basis relate to the observed placental phenotype difference.
