Industrial production of the edible basidiomycete Pleurotus ostreatus (oyster mushroom) is based on a solid fermentation process in which a limited number of selected strains are used. Optimization of industrial mushroom production depends on improving the culture process and breeding new strains with higher yields and productivities. Traditionally, fungal breeding has been carried out by an em...

Current genetic improvement programs should place more emphasis on improving profitability than on one or a small group of traits, under the framework of economic relevance (Golden et al., 2000). When profit is defined generally as revenue minus cost, true economically relevant traits (ERT) have a direct impact on either income or expenses, whereas indicator traits provide a means to increase a...

In the current paper we investigate whether gender aVects the encoding of leadership behavior. In three studies we found evidence that perceivers had diYculty encoding leadership behaviors into their underlying prototypical leadership traits when the behavior implied an agentic trait and the behavior was enacted by a female. Using a lexical decision making task, in Study 1 we demonstrated that ...

Given finite resources, intense investment in one life history trait is expected to reduce investment in others. Although telomere length appears to be strongly tied to age in many taxa, telomere maintenance requires energy. We therefore hypothesize that telomere maintenance may trade off against other life history characters. We used natural variation in laboratory populations of Atlantic silv...

Genome-wide association studies (GWAS) based on high throughput SNP genotyping technologies open a broad avenue for exploring genes associated with milk production traits in dairy cattle. Motivated by pinpointing novel quantitative trait nucleotide (QTN) across Bos Taurus genome, the present study is to perform GWAS to identify genes affecting milk production traits using current state-of-the-a...

Quantitative trait loci affecting economically important traits were studied for eight large US Holstein grandsire families by using the granddaughter design. A total of 155 microsatellite markers located throughout the bovine genome were selected for the scan. The data analyzed include genotypes for 50 markers not previously reported. Results analyses of 105 marker genotypes reported previousl...

Genetic correlations between purebred Duroc (DU), Large White (LW) and Landrace (LR) pigs and their crossbreds LW×LR, LR×LW, DU×(LW×LR) and DU×(LR×LW) were estimated for production and reproduction traits. Performance test and litter records from Government pig breeding stations in Thailand were used. REML bivariate animal models were used to estimate genetic correlations for each trait measure...

correlation between breeding value of crude milk (cm) and energy-corrected milk (ecm) was studied based on a total of 774,013 test day records belongs to 88,456 first-parity holsteins dairy cattle calving during 1997-2009 in 165 herds (from six provinces). genetic analysis of the traits was carried out by a fixed regression test day model. in the model, effects of herd, calving year, production...
