Evaluation of pathways to the C-glycosyl isoflavone puerarin in roots of kudzu (Pueraria montana lobata) (open access)

Evaluation of pathways to the C-glycosyl isoflavone puerarin in roots of kudzu (Pueraria montana lobata)

Article describes how kudzu produces both O- and C-glycosylated isoflavones, with puerarin (C-glucosyl daidzein) as an important bioactive compound. The authors go on to explain how expression of recombinant UGTs in Escherichia coli and candidate C-glycosyltransferases in Medicago truncatula were used to explore substrate specificities, and gene silencing of UGT and key isoflavone biosynthetic genes in kudzu hairy roots employed to test hypotheses concerning the substrate(s) for C-glycosylation.

Technical Memorandum: Lewisville Lake Watershed Protection and Management Strategies (open access)

Technical Memorandum: Lewisville Lake Watershed Protection and Management Strategies

With a current population of just over half a million and a 2030 projected population of approximately one million, expansion throughout Denton County shows no sign of slowing down (NCTCOG). Increasingly, freshwater resources are also facing increased pressure from this urban expansion. Effective assessment and management techniques are necessary to protect the diversity of ecosystem services found within fluvial ecosystems and to mitigate current and future conditions of environmental stressor amplified by urban development. The use of various spatial analysis techniques in environmental assessment present more expedient, cost effective, and broader ranging methods of evaluation than traditional field techniques. One such novel evaluation technique is the Water Quality Corridor Management (WQCM) model, developed by the University of North Texas in cooperation with the Upper Trinity Regional Water District (UTRWD). The WQCM model is a geospatial database that utilizes GIS and remote sensing techniques to assess and prioritize stream reaches according to their overall health and sustainability. This project assessed the viability of the WQCM model in reviewing the status of stream systems, and ultimately, established an accurate mechanism for evaluating the stream corridor and surface water quality draining into Lewisville Lake, a popular recreation site and drinking water source for …

Parental stressor exposure simultaneously conveys both adaptive and maladaptive larval phenotypes through epigenetic inheritance in the zebrafish (Danio rerio) (open access)

Parental stressor exposure simultaneously conveys both adaptive and maladaptive larval phenotypes through epigenetic inheritance in the zebrafish (Danio rerio)

This article is a study using crude oil as an example of an environmental stressor in adult zebrafish. The offspring obtained were then assessed for transgenerational epigenetic transfer of oil-induced phenotypes. The authors conclude that epigenetic transgenerational inheritance can lead to an immediate and simultaneous inheritance of both beneficial and maladaptive traits in a large proportion of the F1 larvae. The adaptive responses may help fish populations survive when facing transient environmental stressors.

Activation of an S6/H4 Kinase (PAK 65) from Human Placenta by Intramolecular and Intermolecular Autophosphorylation (open access)

Activation of an S6/H4 Kinase (PAK 65) from Human Placenta by Intramolecular and Intermolecular Autophosphorylation

Article proposing a model in which phosphorylation of sites 1 and 2 occurs sequentially. The model proposes that trypsin treatment of the inactive holoenzyme removes an inhibitory rac-binding domain which blocks MgATP access to the catalytic site. The pseudosubstrate domain at site 1 is autophosphorylated and subsequent bimolecular autophosphorylation at site 2 fully opens the catalytic site.
