“…Our transcriptional results confirmed the presence of known genes and enzymes in pathways related to the synthesis of flavonoids and carotenoids. These results are in agreement with previous studies that reported the tree tomato as an abundant source of carotenoids, anthocyanins, flavonoids, and phenolic compounds and has higher antioxidant activity than other antioxidant-rich fruits such as kiwifruit or grape [7]. The carotenoid concentration in tree tomato may be under the control of several genes that are associated with the structure and function of the genes in the carotenoid pathway.…”

“…In recent years, the tree tomato has caught the attention of growers and the industry due to its attractive, fleshy, edible fruits, which can be consumed either in salads or as a dessert fruit, or processed for making jams, yogurts, juices, or alcoholic beverages, among others [5]. It has developed from being a neglected crop, with a local interest in subsistence farms [6], into a promising fruit crop, having been introduced in several countries of Oceania, Southeast Asia, Europe and Africa [7]. Aside from South American countries, New Zealand is the largest producer and exporter of the tree tomato, where the marketable word, "tamarillo", was coined from the Maori term "tama", meaning leadership, combined with the Spanish word, "Amarillo", meaning yellow, or the word, "Tomatillo", meaning small tomato [8].…”

The tree tomato (Solanum betaceum Cav.) is an underutilized fruit crop native to the Andean region and phylogenetically related to the tomato and potato. Tree tomato fruits have a high amount of nutrients and bioactive compounds. However, so far there are no studies at the genome or transcriptome level for this species. We performed a de novo assembly and transcriptome annotation for purple-fruited (A21) and an orange-fruited (A23) accessions. A total of 174,252 (A21) and 194,417 (A23) transcripts were assembled with an average length of 851 and 849 bp. A total of 34,636 (A21) and 36,224 (A23) transcripts showed a significant similarity to known proteins. Among the annotated unigenes, 22,096 (A21) and 23,095 (A23) were assigned to the Gene Ontology (GO) term and 14,035 (A21) and 14,540 (A23) were found to have Clusters of Orthologous Group (COG) term classifications. Furthermore, 22,096 (A21) and 23,095 (A23) transcripts were assigned to 155 and 161 (A23) KEGG pathways. The carotenoid biosynthetic process GO terms were significantly enriched in the purple-fruited accession A21. Finally, 68,647 intraspecific single-nucleotide variations (SNVs) and almost 2 million interspecific SNVs were identified. The results of this study provide a wealth of genomic data for the genetic improvement of the tree tomato.

“…Laird’s Large, also known as red type, is the most common cultivar. Tamarillo pulp contains high amounts of dietary fiber, vitamins A, B 6 , C, and E, and minerals (Ca, K, Cu, Fe, Mg, Mn, P, and Zn) [ 2 , 3 , 4 , 5 ]. Chlorogenic acid and kaempferol rutinoside are dominant phenolics in red tamarillo from New Zealand; high concentrations of delphinidin rutinoside and pelargonidin rutinoside were found in this variety [ 1 ].…”

“…Meanwhile, β-carotene and β-cryptoxanthin were identified as the most abundant carotenoids in tamarillo from Australia and Brazil [ 6 ] as well as New Zealand [ 3 ]. Potential health benefits including antioxidant, antiobesity, anticancer, and prebiotic properties of tamarillo fruit have been reported [ 5 ]. Recognized for a distinctive aroma, tamarillo pulp is mostly consumed in the fresh form and the peel is discarded.…”

Tamarillo is a nutrient-dense fruit with a unique aroma from its volatile compounds (VCs). In this study, we aimed to compare the volatile profiles: (i) of fresh and freeze-dried tamarillo; (ii) detected using Thermal Desorption–Gas Chromatography–Mass Spectrometry (TD–GC–MS) and Solid-Phase MicroExtraction–Gas Chromatography-Mass Spectrometry (SPME–GC–MS); (iii) of freeze-dried pulp and peel of New Zealand grown tamarillo. The possible antibacterial activity of freeze-dried tamarillo extracts was also investigated. We show that freeze-drying maintained most of the VCs, with some being more concentrated with the loss of water. The most abundant VC in both fresh and freeze-dried tamarillo was hexanoic acid methyl ester for pulp (30% and 37%, respectively), and (E)-3-Hexen-1-ol for peel (36% and 29%, respectively). With the use of TD–GC–MS, 82 VCs were detected for the first time, when compared to SPME–GC–MS. Methional was the main contributor to the overall aroma in both peel (15.4 ± 4.2 μg/g DW) and pulp (118 ± 8.1 μg/g DW). Compared to water as the control, tamarillo extracts prepared by water and methanol extraction showed significant antibacterial activity against E. coli, P. aeruginosa, and S. aureus with zone of inhibition of at least 13.5 mm. These results suggest that freeze-dried tamarillo has a potential for use as a natural preservative to enhance aroma and shelf life of food products.

Solanum betacea is a sub-tropical tree, and the fruit has high nutritional value, unique flavor and color. It is used as a functional ingredient in health care, food, cosmetic and pharmaceutical applications. The complete chloroplast(Cp) genome of S. betacea has been assembled and annotated in this paper. Its length was 155,937 bp, containing a large single-copy region of 86,731 bp, a small single-copy region of 18,450 bp, and a pair of IR regions of 25,378 bp in each. The complete chloroplast genome of S. betacea contained 134 genes, including 90 protein-coding genes, 36 transfer RNA genes (tRNAs), and 8 ribosome RNA genes (rRNAs). The overall GC content was 37.7% and the GC contents of the LSC, SSC, and IR regions were 35.7%, 31.8%, and 43.1%, respectively. Phylogenetic analysis with the reported chloroplast genomes revealed that S. betacea has been most closely related to Solanum torvum. These findings will provide useful information for further investigation of chloroplast genome evolution in Solanum betacea.
