Genomic loci associated with Fusarium stalk rot resistance and related agronomic traits in maizeNARA Subscribed
Key message Two novel QTLs conferring Fusarium stalk rot resistance were identified in the Kemater flint landrace population, thereby broadening the genetic base for FSR resistance breeding. Given the polygenic inheritance of Fusarium stalk rot resistance, genomic selection could be explored as a potential strategy for improving resistance to stalk rot in maize. Abstract Fusarium stalk rot (FSR) is one of the most prevalent an...
Radiocarbon analysis reveals the contribution of aged terrestrial carbon to sedimentary methane cyclingNARA Subscribed
Methane (CH 4 ) production in lacustrine sediments is known to be spatially heterogeneous, varying both horizontally and vertically. Porewater methane concentrations often differ between locations within a lake and with depth within the sediment profile. The drivers of this heterogeneity are often not well understood. Here, we explore methane cycling in the sediments of Lake Constance, the 2 nd largest perialpine lake in Europ...
From whole bodies to single cells: A guide to transcriptomic approaches for ecology and evolutionary biologyNARA Subscribed
RNA sequencing (RNAseq) methodology has experienced a burst of technological developments in the last decade, which has opened up opportunities for studying the mechanisms of adaptation to environmental factors at both the organismal and cellular level. Selecting the most suitable experimental approach for specific research questions and model systems can, however, be a challenge and researchers in ecology and evolution are co...
Pre‐aged organic matter dominates organic carbon burial in a major perialpine lake systemNARA Subscribed
Organic carbon (OC) burial in lake sediments is comparable to that in marine sediments globally. However, climatic and carbon cycle implications depend on the origin of buried OC. This study utilizes high‐resolution radiocarbon ( 14 C) measurements in combination with stable carbon isotopes ( 13 C) and total organic carbon/total nitrogen ratios to constrain sources and ages of OC deposited since the early 20 th century in Lake...
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...
