Higher yield in tomato by introgression and dissection into light interception and light use efficiencyNARA Subscribed
To genetically improve a complex trait we can dissect it into simpler component traits that follow a physiological model. We investigated this approach in tomato for total plant biomass, which was decomposed into fraction of intercepted light (F int ), calculated from leaf area index (LAI), and light use efficiency (LUE). We identified quantitative trait loci (QTLs) in hybrids created out of a multi-parent population of recomb...
Precision measurement of the Ds*+-Ds+ meson mass differenceNARA Subscribed
The peroxisomal importomer can accommodate an intrinsically disordered protein of 1247 residuesNARA Subscribed
Peroxisomal matrix proteins are nuclear encoded and synthesized in the cytosol. It is well established that folded, cofactor-containing, and even oligomeric matrix proteins can pass the peroxisomal membrane. Here, we studied whether relatively long unfolded proteins can be imported into peroxisomes using the yeast Hansenula polymorpha as a model organism. First, we designed fusion proteins containing parts of the intrinsically...
Penalized factorial regression as a flexible and computationally attractive reaction norm model for prediction in the presence of GxENARA Subscribed
Key message Penalized factorial regression offers a computationally attractive alternative to kernel and deep learning methods for prediction of genotype by environment interactions. For two representative data sets on wheat and maize, prediction accuracies were comparable, while computing requirements and time were clearly lower. Abstract A longstanding challenge in plant breeding and genetics is the prediction of yield for n...
Safeguarding Iguana diversity: enabling rapid and low-effort tracking of non-native iguanas through terrestrial eDNA innovationsNARA Subscribed
Reptiles have among the highest extinction risk across terrestrial vertebrates, with habitat fragmentation, habitat destruction, and invasive alien species being the primary causes of reptile species loss on a global scale. Invasive hybridization (i.e. hybridization between native and invasive alien species) is increasing globally, causing the extinction of native genotypes, and this phenomenon is particularly pervasive in Car...
On 25 August 2022, the Zoologica Scripta ‐ An International Journal of Systematic Zoology and the Norwegian Academy of Sciences and Letters arranged a symposium entitled ‘The role of systematics for understanding ecosystem functions’ in the Academy's premises in Oslo, Norway. The symposium aimed at offering a forum for exploring and discussing trends and future developments in the field of systematics. Eleven international exp...
Variation in species richness across the tree of life, accompanied by the incredible variety of ecological and morphological characteristics found in nature, has inspired many studies to link traits with species diversification. Angiosperms are a highly diverse group that has fundamentally shaped life on earth since the Cretaceous, and illustrate how species diversification affects ecosystem functioning. Numerous traits and pr...
The physiological performance of organisms depends on their environmental context, resulting in performance–response curves along environmental gradients. Parasite performance–response curves are generally expected to be broader than those of their hosts due to shorter generation times and hence faster adaptation. However, certain environmental conditions may limit parasite performance more than that of the host, thereby provi...
Key message We evaluate self-organizing maps (SOM) to identify adaptation zones and visualize multi-environment genotypic responses. We apply SOM to multiple traits and crop growth model output of large-scale European sunflower data. Abstract Genotype-by-environment interactions (G × E) complicate the selection of well-adapted varieties. A possible solution is to group trial locations into adaptation zones with G × E occurring...
In this study, the effect of heterozygous germline mutations in the heparan sulfate (HS) glycosaminoglycan chain co-polymerases EXT1 and EXT2 on glomerular barrier function and the endothelial glycocalyx in humans is investigated. Heparan sulfate (HS) glycosaminoglycans are deemed essential to the glomerular filtration barrier, including the glomerular endothelial glycocalyx. Animal studies have shown that loss of HS results i...
Key message The identity-by-descent (IBD)-based mixed model approach introduced in this study can detect quantitative trait loci (QTLs) referring to the parental origin and simultaneously account for multilevel relatedness of individuals within and across families. This unified approach is proved to be a powerful approach for all kinds of multiparental population (MPP) designs. Abstract Multiparental populations (MPPs) have be...
