Arabidopsis PROTODERMAL FACTOR2 binds lysophosphatidylcholines and transcriptionally regulates phospholipid metabolism.

Plant homeodomain leucine zipper IV (HD-Zip IV) transcription factors (TFs) contain an evolutionarily conserved steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domain. While the START domain is required for TF activity, its presumed role as a lipid sensor is not clear. Here we used tandem affinity purification from Arabidopsis cell cultures to demonstrate that PROTODERMAL FACTOR2 (PDF2), a representative member that controls epidermal differentiation, recruits lysophosphatidylcholines (LysoPCs) in a START-dependent manner.

LMA or vivipary? Wheat grain can germinate precociously during grain maturation under the cool conditions used to induce late maturity alpha-amylase (LMA).

Introduction: This study found that wheat () grain can germinate precociously during the maturation phase of grain development, a phenomenon called vivipary that was associated with alpha-amylase induction. Farmers receive severe discounts for grain with low falling number (FN), an indicator that grain contains sufficiently elevated levels of the starch-digesting enzyme alpha-amylase to pose a risk to end-product quality. High grain alpha-amylase can result from: preharvest sprouting (PHS)/germination when mature wheat is rained on before harvest, or from late maturity alpha-amylase (LMA) when grain experiences cool temperatures during the soft dough stage of grain maturation (Zadoks growth stage 85).

Spatial dimensions of water quality value in New England river networks.

Households' willingness to pay (WTP) for water quality improvements-representing their economic value-depends on where improvements occur. Households often hold higher values for improvements close to their homes or iconic areas. Are there other areas where improvements might hold high value to individual households, do effects on WTP vary by type of improvement, and can these areas be identified even if they are not anticipated by researchers? To answer these questions, we integrated a water quality model and map-based, interactive choice experiment to estimate households' WTP for water quality improvements throughout a river network covering six New England states.

Cause of End-Stage Renal Disease Is Not a Risk Factor for Cytomegalovirus Infection After Kidney Transplant.

Background: Cytomegalovirus infection (CMV) after kidney transplantation leads to increased morbidity and mortality. Whether the cause of end-stage renal disease (ESRD) influences the risk of CMV infection post-transplant is not known.

Methods: We analyzed data from 2741 adult kidney transplant recipients from January 1993 through December 2014.

Embedded performance validity indicator for children: California Verbal Learning Test - Children's Edition, forced choice.

Performance validity testing in children undergoing neuropsychological testing is a growing research area. Accurate identification of performance validity is necessary to avoid invalid assessment conclusions. In the present research, a forced choice (FC) trial was created for the California Verbal Learning Test - Children's Edition (CVLT-C), modeled after the established California Verbal Learning Test - Second Edition (CVLT-II) FC trial.
