THP9 enhances seed protein content and nitrogen-use efficiency in maize
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.

Genomic basis of geographical adaptation to soil nitrogen in rice
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.

A prion-like domain in ELF3 functions as a thermosensor in Arabidopsis
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.

The strength and pattern of natural selection on gene expression in rice
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.

Modulating plant growth–metabolism coordination for sustainable agriculture
The balance of DELLA and GRF4 proteins in plants ensures the co-regulation of growth with metabolism and tipping this balance towards GRF4 leads to higher efficiency of nitrogen use.

Natural allelic variation underlying a major fitness trade-off in Arabidopsis thaliana
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.

Genome-wide association study of 107 phenotypes in Arabidopsis thaliana inbred lines
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.
