Diversifying selection signatures among divergently selected subpopulations of Polish Red cattle.

Diversifying selection signatures among divergently selected subpopulations of Polish Red cattle. J Appl Genet. 2019 Jan 26;: Authors: Gurgul A, Jasielczuk I, Semik-Gurgul E, Szmatoła T, Majewska A, Sosin-Bzducha E, Bugno-Poniewierska M Abstract Polish Red cattle is one of the few indigenous breeds of European red cattle which is characterized by several desired features, such as high disease resistance, good health, longevity, good fertility, and high nutritional value of milk. Currently, Polish Red cattle population is a subject of two independent breeding programs: (i) improvement program and (ii) genetic resources conservation program. The aim of the improvement program is the genetic progress in terms of milk production and body conformation traits, while the conservation program mainly focuses on protection of the genetic resources of Polish Red cattle and preservation of the existing, original gene pool. By the analysis of FST genetic distances across genome-wide SNP panel, we detected diversifying selection signatures among these two subpopulations and indicated (among others) the significance of DGAT1 and FGF2 genes for milk production traits in these cattle. We also found that among genes being presumably under selection in terms of milk production, there are genes responsible, for example, for mammary gland development (e.g., SOSTDC1, PYGO2, MED1, and CCND1) and immune system response (e.g., IL10RA, IL12B, and IL21).
