Contrasting the genetic architecture of cardiac glutathione against other organs: unveiling a unique tissue-specific locusNARA Subscribed
Glutathione is a ubiquitous antioxidant with critical roles in xenobiotic clearance and aerobic metabolism. Reduced glutathione (GSH) is converted to its oxidized counterpart, GSSG, in the process of neutralizing free radicals and maintaining biochemical homeostasis. An imbalance between free radical generation and antioxidant protection leads to oxidative stress and diminished GSH concentrations. Polymorphisms in GSH synthesi...
Genetic background variability influences novel ARS grain sorghum productivity and resource partitioningNARA Subscribed
A recent focus for sorghum [ Sorghum bicolor (L.) Moench] improvement deals with the introgression of multi-seed ( MSD ) alleles into genetic backgrounds by leveraging genomic tools and combining it with the stay-green trait to improve yield potential and stability in resource-limited environments. A key challenge in these efforts is optimizing resource partitioning and efficiently allocating assimilates and nutrients to repro...
From field to sky: measurement and modeling of transgenic switchgrass pollen dispersal in the atmosphereNARA Subscribed
Accurate tracking and measurement of pollen dispersal in the atmosphere are essential for assessing cross-pollination risks, particularly in the case of genetically engineered (GE) crops. We conducted a series of unique release-recapture field studies with GE switchgrass in Oliver Springs, TN, USA. Two hundred transgenic switchgrass plants ( Panicum virgatum L. “Performer”) were planted at the center of a clear-cut field, with...
Use of translational fusions to express functional Klebsiella oxytoca dinitrogenase reductase in plant mitochondriaNARA Subscribed
Engineering crop plants with the biological nitrogen fixation pathway is a longstanding goal of modern agriculture. Dinitrogenase reductase (NifH) is a critical component of the biological nitrogen fixation pathway, with multiple roles in metal cofactor assembly and catalysis. This enzyme must be folded correctly as a soluble homodimer and loaded with the [4Fe-4S] metallocluster for function. Previous studies have found that K...
Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this...
Genotype-by-environment interactions and local adaptation shape selection in the US National Chip Processing TrialNARA Subscribed
Key message We find evidence of selection for local adaptation and extensive genotype-by-environment interaction in the potato National Chip Processing Trial (NCPT). Abstract We present a novel method for dissecting the interplay between selection, local adaptation and environmental response in plant breeding schemes. Balancing local adaptation and the desire for widely adapted cultivars is challenging for plant breeders and m...
Creating conservation strategies with value‐focused thinkingNARA Subscribed
Biodiversity and human well‐being strategies are only as good as the set of ideas people think about. We evaluated value‐focused thinking (VFT), a framework that emphasizes creating objectives and strategies that are responsive to the objectives. We performed a proof‐of‐concept study of VFT with 6 conservation planning teams at a global conservation organization. We developed a package of materials related to VFT, including me...
