Purpose Many abdominal aortic aneurysm (AAA) patients develop intraluminal thrombus (ILT), but the role of ILT in AAA progression and rupture is poorly understood. Methods To evaluate ILT in AAAs, we induced AAAs in C57Bl6/J mice via surgical application of topical elastase to the abdominal aorta below the renal arteries and administration of β-aminopropionitrile (BAPN) in drinking water. Ultrasound images of these AAAs were c...
Rapid cycling genomic selection in maize landraces: a step toward closing the yield gapNARA Subscribed
Key message Rapid cycling genomic selection is a highly efficient tool for pre-breeding of maize landraces for complex traits, especially in combination with multi-trait selection and model retraining. Abstract The introduction of landrace-derived material into modern breeding programs can only succeed if it performs satisfactorily for yield and other key agronomic traits. In this study, we explored the prospects of rapid cycl...

Rapid cycling genomic selection in maize landracesNARA Subscribed
Key message A replicated experiment on genomic selection in a maize landrace provides valuable insights on the design of rapid cycling recurrent pre-breeding schemes and the factors contributing to their success. Abstract The genetic diversity of landraces is currently underutilized for elite germplasm improvement. In this study, we investigated the potential of rapid cycling genomic selection for pre-breeding of a maize ( Zea...

Optimizing selection based on BLUPs or BLUEs in multiple sets of genotypes differing in their population parametersNARA Subscribed
Key message Selection response in truncation selection across multiple sets of candidates hinges on their post-selection proportions, which can deviate grossly from their initial proportions. For BLUPs, using a uniform threshold for all candidates maximizes the selection response, irrespective of differences in population parameters. Abstract Plant breeding programs typically involve multiple families from either the same or d...
Pollen DNA metabarcoding reveals cryptic diversity and high spatial turnover in alpine plant–pollinator networksNARA Subscribed
Alpine plant–pollinator communities play an important role in the functioning of alpine ecosystems, which are highly threatened by climate change. However, we still have a poor understanding of how environmental factors and spatiotemporal variability shape these communities. Here, we investigate what drives structure and beta diversity in a plant–pollinator metacommunity from the Australian alpine region using two approaches:...
Influence of the mating design on the additive genetic variance in plant breeding populationsNARA Subscribed
Key message Mating designs determine the realized additive genetic variance in a population sample. Deflated or inflated variances can lead to reduced or overly optimistic assessment of future selection gains. Abstract The additive genetic variance $${V}_{A}$$ V A inherent to a breeding population is a major determinant of short- and long-term genetic gain. When estimated from experimental data, it is not only the additive var...
Genomic prediction in hybrid breeding: II. Reciprocal recurrent genomic selection with full-sib and half-sib familiesNARA Subscribed
Key message Genomic prediction of GCA effects based on model training with full-sib rather than half-sib families yields higher short- and long-term selection gain in reciprocal recurrent genomic selection for hybrid breeding, if SCA effects are important. Abstract Reciprocal recurrent genomic selection (RRGS) is a powerful tool for ensuring sustainable selection progress in hybrid breeding. For training the statistical model,...
Achieving conservation outcomes in plant mitigation translocations: the need for global standardsNARA Subscribed
Many countries have legislation intended to limit or offset the impact of anthropogenic disturbance and development on threatened plants. Translocations are often integral to those mitigation policies. When translocation is used exclusively to mitigate development impacts, it is often termed a ‘mitigation translocation.’ However, both the terminology and processes vary regarding interpretation and application, resulting in inc...
Key message Training sets produced by maximizing the number of parent lines, each involved in one cross, had the highest prediction accuracy for H0 hybrids, but lowest for H1 and H2 hybrids. Abstract Genomic prediction holds great promise for hybrid breeding but optimum composition of the training set (TS) as determined by the number of parents ( n TS ) and crosses per parent ( c ) has received little attention. Our objective...
