Influence of two sources of information on the accuracy of fertility and hatchability proofs in laying hens was studied on a Rhode Island White-based maternal strain record. Five- or three-generation pedigree and including or not including the laying performance as correlated traits were varied to create four variants of analysis tested against the reference – five-generation, multiple-trait, and...
The purpose of the study was to evaluate the multiple-trait model, as opposite to repeatability model approach, at an early stage of developing the breeding value estimation system for dairy goats in Poland. Milk, fat, and protein yields and fat and protein contents in first (4,443 records) and following parities (9,115 records of 5,244 goats) were analysed as two separate traits within a trait.Variance...
Glucosyltransferases were isolated and characterised from many plant sources. The enzymes show middle amino acid similarity and broad substrate specificity. The promoter of the potato 5-UGT gene reveals strong environmental induction. The activation of the gene expression by UV radiation, ABA and cold treatments was detected. Overexpression of 5-UGT resulted in the accumulation of the diglucoside...
