miRNAs and lncRNAs, which represent one of the most highly expressed classes of ncRNAs in development, are attracting increasing interest. A variety of regulators is considered to be implicated in sheep species with different fecundity. However, interactions between miRNAs and lncRNAs and changes in the expression of regulatory lncRNAs in sheep fecundity have not yet been reported. To character...

The tendency to dizygotic (DZ) twinning is inherited in both humans and sheep, and a fecundity gene in sheep (FecB) maps to sheep chromosome 6, syntenic with human 4q21-25. Our aim was to see whether a gene predisposing to human DZ twinning mapped to this region. DNA was collected from 169 pairs and 17 sets of 3 sisters (trios) from Australia and New Zealand who had each had spontaneous DZ twin...

Wheat, the world’s most widely cultivated crop, is highly susceptible to Take-all disease caused by soil ascomycete fungus Gaeumannomyces tritici (Gt). Crop rotations using different wheat cultivars can influence build up (TAB) in following year’s crop. The exact mechanism for this unknown, but there may be a bacterial biocontrol component associated with TAB control. We cultured and characteri...

Small Tail Han sheep, including the FecBBFecBB (Han BB) and FecB+ FecB+ (Han++) genotypes, and Dorset sheep exhibit different fecundities. To identify novel long non-coding RNAs (lncRNAs) associated with sheep fecundity to better understand their molecular mechanisms, a genome-wide analysis of mRNAs and lncRNAs from Han BB, Han++ and Dorset sheep was performed. After the identification of diffe...

one of the traits of the greatest financial impact on sheep production is the number of lambs weaned per ewe with fecb considered as the most well known major gene concerned with this trait. in order to conduct a marker assisted introgression (mai) program the presence of fecb responsible mutation in afshari sheep breeding flock was surveyed. direct test to detect fecbb allele was conducted on ...
