  • Zachary Lippman, Dani Zamir and colleagues report that the flowering gene, SINGLE FLOWER TRUSS, displays heterosis for fruit yield in tomato. Heterozygosity at this gene in several distinct genetic backgrounds leads to increases of up to 60% in fruit yield.

  • The complete DNA sequences of the two wild parents of the garden petunia provide valuable genetic insights into this model plant, and will improve the optimization of other crop plants for agriculture.

  • A new mapping study identifies a natural protein variant influencing oil content and composition in maize seeds. This example illustrates the power of exploiting natural variation to improve crop yields and address current breeding challenges.

  • Zachary Lippman and colleagues report the recovery in tomato of novel, chemically induced alleles in the SFT (florigen) gene and a newly identified suppressor of the SELF PRUNING gene. These alleles, in combination with previous florigen pathway mutations, allow for the quantitative fine-tuning of fruit yield, which may be applicable to other crop species.

  • Steroidal glycoalkaloids (SGAs) accumulate in Solanum, but their hydroxylating enzymes are unknown. Here, the authors report 2-OXOGLUTARATE DEPENDENT DIOXYGENASE enzymes that catalyze the committed hydroxylation steps in the biosynthesis of leptinine insecticidal compounds in wild potato or non-bitter SGAs in cultivated tomato.

  • Bitterness is one of the fruit traits that are most disliked by consumers. In this study, the authors identified and characterized a tonoplast membrane transporter in tomato fruit, which is responsible for the translocation of bitter α-tomatine and other derivatives from the vacuole to the cytoplasm for non-bitter conversion.

  • A study of 580 tomato lines resulting from a cross between a wild desert-adapted species and a domesticated cultivar elucidates the genetic basis of gene expression and metabolite variation associated with fruit traits and defense against pathogens.

  • Sanwen Huang and colleagues report a comprehensive analysis of genetic variation in tomato based on the genome sequencing of 360 distinct accessions. The work provides insights into the history of tomato domestication and represents a rich resource for studying the genetic basis of trait variation in this important crop plant.

  • Björn Usadel and colleagues report the genome sequence of the wild tomato species Solanum pennellii. The authors identify genes important for stress tolerance, metabolism and fruit maturation and suggest that transposable elements have had an important role in the evolution of the S. penellii stress response.

  • This paper reports the genome sequence of domesticated tomato, a major crop plant, and a draft sequence for its closest wild relative; comparative genomics reveal very little divergence between the two genomes but some important differences with the potato genome, another important food crop in the genus Solanum.

  • José M. Jiménez-Gómez and colleagues report that the circadian clock of cultivated tomato was quantitatively slowed during domestication compared to its wild relatives, based on measurements of circadian leaf movements. They map QTL for phase and period, and identify the causal gene, EID1, underlying the phase QTL.
