TL;DR: A map of the barley genome consisting of 295 loci was constructed, which includes 152 cDNA restriction fragment length polymorphism (RFLP), 114 genomic DNA RFLP, 14 random amplified polymorphic DNA (RAPD), five isozyme, two morphological, one disease resistance and seven specific amplicon polymorphism

TL;DR: It is found that the genomic architecture of flowering time has been shaped by the most recent whole-genome duplication, which suggests that ancient paralogues can remain in the same regulatory networks for dozens of millions of years.
Journal ArticleDOI
Systemic Endopolyploidy in Arabidopsis thaliana
TL;DR: Microfluorometric analysis of the nuclear DNA contents of the somatic tissues of Arabidopsis thaliana has revealed extensive endoreduplication, resulting in tissues that comprise mixtures of polyploid cells.
Journal ArticleDOI
Quantitative trait locus effects and environmental interaction in a sample of North American barley germ plasm.

TL;DR: Quantitative trait locus (QTL) and QTL x environment (E) interaction effects for agronomic and malting quality traits were measured using a 123-point linkage map and multi-environment phenotype data from an F1-derived doubled haploid population of barley.
Journal ArticleDOI
Origin and evolution of the octoploid strawberry genome.

TL;DR: A near-complete chromosome-scale assembly for cultivated octoploid strawberry (Fragaria × ananassa) is reported and the origin and evolutionary processes that shaped this complex allopolyploid are uncovered, providing a useful resource for genome-wide analyses and molecular breeding.
