Tomato (Solanum lycopersicum) is one of the world’s most extensively cultivated crops, and has been the subject of hundreds of years of breeding and selection. Nevertheless, the genetic variability available for the breeding and improvement of tomato within the confines of the species is limited. This has been described as a “genetic bottleneck” (Miller and Tanksley 1990) and is due to the domestication history of the crop, particularly the transfer of select germplasm from South America to Europe in the 1500 s, followed by selections and return to the New World, again of limited germplasm (Knapp and Peralta 2016). In this paper we report and make available to the research community an extensive data of gene transcript information (whole-transcript RNA-seq) from fruit of 44 tomato accessions, comprising two studies. The first compares transcriptomes of four stages of fruit development, from immature green to ripe, of 16 accessions. These include 4 lycopersicum, 2 pimpinellifolium, 2 cheesmaniae, 3 chmielewskii, 2 habrochaites, 2 peruvianum and a single pennellii accession (listed in Supplementary Table S1). The expression data for the developing fruit are presented in Supplementary Table S2. The second study compares the transcriptomes of ripe fruit of 32 additional accessions (listed in Supplementary Table S1), comprising 16 pimpinellifolium (8 of Ecuadorian origin and 8 of Peruvian origin), 8 cheesmaniae and 8 galapagense. These data are presented in Supplementary Table S3. In total, ~ 1.5 billion reads were obtained from 129 libraries derived from 93 samples and mapped against the reference Heinz 1706 genome v4 (Supplementary Table S4).
