Isolation and mapping of self-assembling protein domains encoded by the Saccharomyces cerevisiae genome using lambda repressor fusions

Understanding how proteins are able to form stable complexes is of fundamental interest from the perspective of protein structure and function. Here we show that lambda repressor fusions can be used to identify and characterize homotypic interaction domains encoded by the genome of Saccharomyces cerevisiae, using a selection for polypeptides that can drive the assembly of the DNA binding domain of bacteriophage lambda repressor. Three high complexity libraries were constructed by cloning random fragments of S. cerevisiae DNA as lambda repressor fusions. Repressor fusions encoding homotypic interactions were recovered, identifying oligomerization units in 35 yeast proteins. Seventeen of these interaction domains have not been previously reported, while the other 18 represent homotypic interactions that have been characterized at varying levels of detail. The novel interactions include several predicted coiled-coils as well as domains of unknown structure. With the availability of genomic sequences it should be possible to apply this approach, which provides information about protein-protein interactions that is complementary to that obtained from yeast two-hybrid screens, on a genome-wide scale in yeast or other organisms where large-scale protein-protein interaction data is not available.     

Multiple-marker mapping for selective DNA pooling within large families

Selective DNA pooling is a very powerful method for quantitative trait loci (QTL) mapping. It considerably reduces genotyping costs while maintaining high statistical power. Applied to a daughter design, milk samples of offspring with extreme phenotypic values for a trait of interest are assigned to high and low groups, respectively, and within each group the pooled DNA is used for densitometric estimation of allele frequencies in the 2 groups. A single-marker test for linkage between marker and QTL considers marker allele frequency differences between high and low groups. Single-marker across-sire test statistics are strongly affected by the number of sires that are heterozygous for a given marker and the QTL status (homozygous or heterozygous) of these sires, which decreases the accuracy of QTL mapping. Here we propose a simple method to deal with this problem by taking information from multiple linked markers into account. In particular, given the single-marker test statistics, a multiple-marker method was developed to predict test statistics for markers for which a sire was homozygous (or at any other location on the chromosome). Power and map resolution of the proposed method were assessed by simulation, and we show that for the same data set, multiple-marker mapping performed better than the commonly used single-marker analyses.     

Consumer acceptance of new strawberry vinegars by preference mapping

Consumers’ acceptance of new strawberry vinegars was evaluated, and trained panellists described their sensory profiles. Four strawberry vinegars, three produced from puree and one from cooked must, were evaluated jointly. Due to obtaining the highest percentage of consumer acceptance, cooked strawberry must vinegar was considered to be the best. This vinegar stood out in general impression, raisin, and liqueur attributes. Internal preference maps confirmed a higher acceptance level for the strawberry vinegars over commercial vinegar. External preference mapping, obtained by PLS2 analysis, revealed that the main sensory attributes driving consumers’ preferences are raisin, toasted caramel, spicy, and liqueur aroma.

A single-layer stitched electrotextile as flexible pressure mapping sensor

In this paper, a stitched fabric for decoding the pressure distribution information by means of resistive sensing is introduced. The proposed fabric-structured sensor is constructed by a distributed resistive array of two orthogonally contacted electrical conductive yarns system, which needs not any external sensing elements to be attached on the fabric. The conductive yarns served as the sensing and wiring elements simultaneously, which in turn simplify the fabrication process and decrease the cost, make the production of large area flexible pressure sensor possible. The topology of the sensing elements distributed on the fabric can be set by stitching the conductive yarn on the substrate fabric by sewing or embroidery machine. The location and pressure applied on the fabric can be obtained by detecting the position where the change of the resistances occurs between two embroidered yarns system. Meanwhile, the magnitude of the pressure can be acquired by measuring the variations of the resistance under pressure. Coating is applied on the contact points of the two yarns system to increase the sensitivity and stability. It is found from the experimental results that the sensitivity and stability are improved dramatically after coating. The resistance vs. pressure exhibits a nonlinear “two stages” mode and the contacting resistance is unstable at small pressure region. The electronics system that picks up the signal of the resistance matrix is also introduced. Flexible, robust, light weight, and breathable provide the sensor advantages to be used as wearable sensors. Meanwhile, easy fabrication and low costs make large area sensing such as sensing carpet possible.
