Double Reduction in Allotetraploid Peanut and the Role of Chromosomal Imbalance in Unexpected Linkage Map Artifacts

Abstract Polyploidization in peanut (Arachis hypogaea L.) fixed heterosis but also caused a genetic bottleneck isolating cultivated peanut from its wild diploid relatives. Mechanisms such as homoeologous exchange can partially restore genetic diversity by generating new allelic c...

Genome-wide prediction and association mapping of potato common scab with historical data

Abstract Common scab, caused by Streptomyces spp., is worldwide an important skin disease of potato, capable of significant reductions in marketable value. Resistant varieties developed through phenotypic selection have been the most effective strategy thus far. Previous studies...

Ribosome stalling position, spacing, and A-site occupancy impact translation and cotranslational mRNA decay in plants

Abstract Rate limitation in translational elongation causes ribosomes to pause as they decode an open reading frame (ORF). The triggers and outcomes of these events are poorly understood in plants. Here, we size, map, and quantify footprints of individual (monosome) and closely s...

Haplotype phasing of de novo chromosome-level assembly of ‘Antonovka’ facilitated the identification of candidate genes for apple scab resistance

Malus genomic resources with improved quality are becoming an integral part of candidate gene identification and functional validation. Recently, we released a reference-based phased chromosome-level genome assembly of ‘Antonovka’ 172670B Malus domestica cultivar from the ‘Antono...
