Whole Genome Sequencing Reveals How Plasticity and Genetic Differentiation Underlie Sympatric Morphs of Arctic Charr.

Salmonids have a remarkable ability to form sympatric morphs after postglacial colonisation of freshwater lakes. These morphs often differ in morphology, feeding and spawning behaviour. Here, we explored the genetic basis of morph differentiation in Arctic charr (n = 283) by first establishing a high-quality reference genome and then using this in whole genome sequencing of distinct morphs present in two Norwegian and two Icelandic lakes.

Nuclear and Mitochondrial Genome Assemblies for the Endangered Wood-Decaying Fungus Somion occarium.

Somion occarium is a wood-decaying bracket fungus belonging to an order known to be rich in useful chemical compounds. Despite its widespread distribution, S. occarium has been assessed as endangered on at least 1 national Red List, presumably due to loss of old-growth forest habitat.

Chromosome-scale genome assembly and de novo annotation of Alopecurus aequalis.

Alopecurus aequalis is a winter annual or short-lived perennial bunchgrass which has in recent years emerged as the dominant agricultural weed of barley and wheat in certain regions of China and Japan, causing significant yield losses. Its robust tillering capacity and high fecundity, combined with the development of both target and non-target-site resistance to herbicides means it is a formidable challenge to food security. Here we report on a chromosome-scale assembly of A.

The genome sequence of the Violet Carpenter Bee, Xylocopa violacea (Linnaeus, 1785): a hymenopteran species undergoing range expansion.

We present a reference genome assembly from an individual male Violet Carpenter Bee (Xylocopa violacea, Linnaeus 1758). The assembly is 1.02 gigabases in span.

"I have a Ph.D. in my daughter": Mother and Child Experiences of Living with Childhood Chronic Illness.

Children in the United States are increasingly living with chronic illnesses. Existing literature has focused on adolescent children's experiences. The current study involved interviews with 10 families: children (ages 6-11) diagnosed with chronic illnesses and their mothers to better understand the experience of living with chronic illness.

Allosteric Site on SHIP2 Identified Through Fluorescent Ligand Screening and Crystallography: A Potential New Target for Intervention.

Src homology 2 domain-containing inositol phosphate phosphatase 2 (SHIP2) is one of the 10 human inositol phosphate 5-phosphatases. One of its physiological functions is dephosphorylation of phosphatidylinositol 3,4,5-trisphosphate, PtdIns(3,4,5)P. It is therefore a therapeutic target for pathophysiologies dependent on PtdIns(3,4,5)P and PtdIns(3,4)P.

Regioisomeric Family of Novel Fluorescent Substrates for SHIP2.

SHIP2 (SH2-domain containing inositol 5-phosphatase type 2) is a canonical 5-phosphatase, which, through its catalytic action on PtdInsP, regulates the PI3K/Akt pathway and metabolic action of insulin. It is a drug target, but there is limited evidence of inhibition of SHIP2 by small molecules in the literature. With the goal to investigate inhibition, we report a homologous family of synthetic, chromophoric benzene phosphate substrates of SHIP2 that display the headgroup regiochemical hallmarks of the physiological inositide substrates that have proved difficult to crystallize with 5-phosphatases.

A Fluorescent Probe Identifies Active Site Ligands of Inositol Pentakisphosphate 2-Kinase.

Inositol pentakisphosphate 2-kinase catalyzes the phosphorylation of the axial 2-OH of myo-inositol 1,3,4,5,6-pentakisphosphate for de novo synthesis of myo-inositol hexakisphosphate. Disruption of inositol pentakisphosphate 2-kinase profoundly influences cellular processes, from nuclear mRNA export and phosphate homeostasis in yeast and plants to establishment of left-right asymmetry in zebrafish. We elaborate an active site fluorescent probe that allows high throughput screening of Arabidopsis inositol pentakisphosphate 2-kinase.
