DIFFERENTIAL SELECTION ON CAROTENOID BIOSYNTHESIS GENES AS A FUNCTION OF GENE POSITION IN THE METABOLIC PATHWAY: A STUDY ON THE CARROT AND DICOTS.

Differential selection on carotenoid biosynthesis genes as a function of gene position in the metabolic pathway: a study on the carrot and dicots.

Selection of genes involved in metabolic pathways could target them differently depending on the position of genes in the pathway and on their role in controlling metabolic fluxes.This hypothesis was tested in the carotenoid biosynthesis pathway using population genetics and phylogenetics.Evolutionary rates of seven genes distributed along the caro

BOA: A partitioned view of genome assembly

Summary: De novo genome assembly is a fundamental problem in computational molecular biology that aims to crescent moon phase blade reconstruct an unknown genome sequence from a set of short DNA sequences (or reads) obtained from the genome.The relative ordering of the reads along the target genome is not known a priori, which is one of the main co

Rare transitional cell carcinoma of the lacrimal sac

Purpose: Transitional cell carcinomas of the lacrimal sac are rare with less than 55 cases reported in the literature.These tumors typically present with a medial canthal mass and epiphora.Observations: Here we describe a 63-year-old male dosatron d40mz2 who presented originally with complaints of dry eye and chronic epiphora.Over the next six mont

Targeted and Untargeted Metabolomics Profiling of Wheat Reveals Amino Acids Increase Resistance to Fusarium Head Blight

Fusarium head blight (FHB), a notorious plant disease caused by Fusarium graminearum (F.graminearum), is severely harmful to wheat production, resulting in a decline in grain quality and yield.In order to develop novel control strategies, metabolomics has been increasingly used to characterize more comprehensive profiles of the mechanisms of underl
