Background Different yellow pigments can be responsible for the yellow colouration of flowers. This includes the wide-spread carotenoids, but also betalains, quinones, yellow flavonoids and anthochlore pigments (chalcones and aurones). Many popular ornamental plants do not produce yellow varieties or only ivory and pale yellow varieties despite of intensive conventional breeding efforts. World-...

We have visualized redox and structural changes in the mitochondria of yeast Saccharomyces cerevisiae as a eukaryotic cell model using a genetically encoded yellow fluorescent protein (Y1-Yellow) and conventional fluorescence microscopy. Y1-Yellow originating from a yellow emitting luminous bacterium Aliivibrio sifiae Y1 was fused with a mitochondria-targeted sequence (mt-sequence). Y1-Yellow f...

Breeding of yellow-seeded rapeseed (Brassica napus) is preferred over black-seeded rapeseed for the desirable properties of the former. This study evaluated the metabolites and nutritive values of black-seeded rapeseed meal and yellow-seeded meal from the progeny of a B. napus-Sinapis alba hybrid. Yellow-seed meal presented higher protein (35.46% vs. 30.29%), higher sucrose (7.85% vs. 7.29%), l...

Purposeful attraction and aggregation of adult Coccinellidae at target sites would be useful for sampling purposes and pest suppression. We field-tested 1) lures in yellow and black pyramidal traps and 2) pyramidal traps that had been painted one or two colors (without lures) to determine if lures or trap color affected capture of adult Coccinellidae. In only one experiment with lures did a sin...

A differential diagnosis must be made between transient yellow discoloration of the nails and yellow nail syndrome. We highlight some practical aspects of yellow nail discoloration.

A chimeric plant was observed in the F(2) generation of a cross between a male-sterile line and a plant introduction homozygous for a chromosome interchange in soybeans [Glycine max (L.) Merr.]. F(3) progeny of this plant included one chimera, 36 yellow plants and 16 green plants. The yellow plants, which progressively turn green, were viable and fertile in field, greenhouse and growth-chamber ...

This is a piece from the annual Yale Internal Medicine Residency Program's Writers' Workshop, which began in 2003. Abraham Verghese and Richard Selzer, among the best known physician-writers in the United States, have served as workshop leaders, teaching the craft of writing to more than 35 residents. In designing the workshop, Anna B. Reisman, assistant professor in the Department of Internal ...

objectives : optimum viewing conditions facilitate identification of radiographic details and decrease the need for retakes, patients’ costs and radiation dose. this study sought to evaluate the effects of different viewing conditions on radiographic interpretation. materials and methods: this diagnostic study was performed by evaluating radiograph of a 7mm-thick aluminum block, in which 10 hol...
