Plant breeding for diversified cropping systems: two inspiring cases from Nepal and FranceNARA Subscribed
This paper reviews recent research articles published in Euphytica on breeding for intraspecific diversification (genotype mixtures) and mixed cropping of different species. We highlight several aspects that these papers have in common, including the use of novel approaches to overcome resource constraints, such as low mechanization, external input availability, or farm labor scarcity. We also discuss how these research articl...
Long-term historical data on the presence of invasive pests can inform current pest management. By examining correlations between shifts in pest occurrences and various potential drivers, we can better inform decision-making and management strategies. However, the availability of such long-term data is often limited. We apply a data rescue protocol to recover difficult-to-access pest information from periodical annual forestry...
Identification of two mutant JASON-RELATED genes associated with unreduced pollen production in potatoNARA Subscribed
Key message Multiple QTLs control unreduced pollen production in potato. Two major-effect QTLs co-locate with mutant alleles of genes with homology to AtJAS, a known regulator of meiotic spindle orientation. Abstract In diploid potato the production of unreduced gametes with a diploid (2 n ) rather than a haploid ( n ) number of chromosomes has been widely reported. Besides their evolutionary important role in sexual polyploid...
Nonsense mutation in the novel PERCC1 gene as a genetic cause of congenital diarrhea and enteropathyNARA Subscribed
Congenital diarrheas and enteropathies (CODEs) constitute a heterogeneous group of individually rare disorders manifesting with infantile-onset chronic diarrhea. Genomic deletions in chromosome 16, encompassing a sequence termed the ‘intestine-critical region (ICR)’, were recently identified as the cause of an autosomal recessive congenital enteropathy. The regulatory sequence within the ICR is flanked by an unannotated open r...
Implementing post-normal science with or for EU policy actors: using quantitative story-tellingNARA Subscribed
There is increasing recognition of the wicked nature of the intertwined climate, biodiversity and economic crises, and the need for adaptive, multi-scale approaches to understanding the complexity of both the problems and potential responses. Most science underpinning policy responses to sustainability issues, however, remains overtly apolitical and focussed on technical innovation; at odds with a critical body of literatures...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Key message In polyploids, linkage mapping is carried out using genotyping with discrete dosage scores. Here, we use probabilistic genotypes and we validate it for the construction of polyploid linkage maps. Abstract Marker genotypes are generally called as discrete values: homozygous versus heterozygous in the case of diploids, or an integer allele dosage in the case of polyploids. Software for linkage map construction and/or...
Multi-allelic QTL analysis of protein content in a bi-parental population of cultivated tetraploid potatoNARA Subscribed
Protein content is a key quality trait for the potato starch industry. The objective of this study was to identify allele-specific quantitative trait loci (QTLs) for tuber protein content in cultivated potato ( Solanum tuberosum L.) at the tetraploid level. We analysed 496 full-sib F 1 clones in a 3-year field trial to dissect the complex genetic architecture of soluble tuber protein content. Genotypic data from a 60K single n...
Multilocus phylogeography reveals nested endemism in a gecko across the monsoonal tropics of AustraliaNARA Subscribed
Multilocus phylogeography can uncover taxonomically unrecognized lineage diversity across complex biomes. The Australian monsoonal tropics include vast, ecologically intact savanna‐woodland plains interspersed with ancient sandstone uplands. Although recognized in general for its high species richness and endemism, the biodiversity of the region remains underexplored due to its remoteness. This is despite a high rate of ongoin...
