TL;DR: A comprehensive analysis of tomato evolution based on the genome sequences of 360 accessions provides evidence that domestication and improvement focused on two independent sets of quantitative trait loci (QTLs), resulting in modern tomato fruit ∼100 times larger than its ancestor.

TL;DR: The genome sequence of segmental allotetraploid peanut is reported and suggests that diversity generated by genetic deletions and homeologous recombination helped to favor the domestication of Arachis hypogaea over its diploid relatives.

TL;DR: It is suggested that loss of SlMlo1 function is responsible for powdery mildew resistance conferred by ol-2, and the second example of a natural mlo mutant that possibly arose post-domestication is revealed, suggesting thatnatural mlo alleles might be evolutionarily short-lived due to fitness costs related to loss of mlo function.

TL;DR: Investigation of the involvement of the Mlo genes in susceptibility to the endophytic fungus L. taurica confirmed the role of CaMlo2 acting as a susceptibility factor to different powdery mildews, though therole ofCaMlo1 as a co-factor for susceptibility cannot be excluded.

TL;DR: Ph-3 is the first cloned tomato gene for resistance to late blight and encodes a CC-NBS-LRR protein, which shares high amino acid identity with the chromosome-9-derived potato resistance proteins against P. infestans.
