    Genetic analyses of teosinte, the wild ancestor of maize, identify a locus (THP9) that is associated with high seed protein content and increased nitrogen-use efficiency, suggesting that THP9 could have applications in crop breeding.

    OsTCP19 is a modulator of the tillering response to nitrogen in rice, and introgression of an allele of OsTCP19 associated with a high tillering response into modern rice cultivars markedly improves their nitrogen-use efficiency.

    The adaptability of the plant Arabidopsis thaliana to different temperatures is regulated by the ability of its ELF3 protein to undergo liquid–liquid phase separation, in a manner that is dependent on the protein’s prion-like domain.

    Phenotypic selection analysis is used to estimate the type and strength of selection that acts on more than 15,000 transcripts in rice (Oryza sativa), which provides insight into the adaptive evolutionary role of selection on gene expression.

    Analyses of genetic variation and population structure based on over 3,000 cultivated rice (Oryza sativa) genomes reveal subpopulations that correlate with geographic location and patterns of introgression consistent with multiple rice domestication events.

    Insights into the genomic architecture of heterosis for grain yield in rice are presented, and further mapping of grain yield loci resolves candidate genes that could be useful for breeding.

    Here, a combination of forward genetics and genome-wide association analyses has been used to show that variation at a single genetic locus in Arabidopsis thaliana underlies phenotypic variation in vegetative growth as well as resistance to infection. The strong enhancement of resistance mediated by one of the alleles at this locus explains the allele's persistence in natural populations throughout the world, even though it drastically reduces the production of new leaves.

    Here, large-scale genome-wide association studies were carried out with the naturally occurring inbred lines of Arabidopsis thaliana, which can be genotyped once and phenotyped repeatedly. The results range from significant associations, usually corresponding to single genes, to findings that are more difficult to interpret, because confounding by complex genetics and population structure makes it hard to distinguish true associations from false.
