Tree Tomato | ScienceGate

In Colombia, a high amount of fruit waste is currently generated. These causes a negative environmental impact due to its high organic load. However, this type of waste has compounds in its structure that can be used in order to reduce the environmental impact and to obtain added value. The main of this study was to characterize bromatologically sixteen residues of fruit processing in Colombia, in order to propose a possible use in the food industry. The bromatological characterization of the waste was carried out by means of the quantification of dry matter (ASTM E1756-08), ash (ASTM E1755-01), proteins (Kjeldahl method), crude fats (AOAC Official Method), total dietary fiber (AOAC 993.21) and carbohydrates. It was found that grape and soursop seeds, lulo peel and tree tomato stem presents the highest total dietary fiber with content percentages above 50 %. Also, tree tomato, soursop, tangerine and orange seeds are an important source of protein and crude fats, with values highest than 12 and 27 %, respectively. It was also found that pineapple, mango, soursop and grape peel have a carbohydrate content greater than 50%. As a conclusion, the results of this study demonstrate that fruit waste have a potential use in the food industry, due to their protein, crude fat, total dietary fiber and carbohydrates content.

Tree Tomato

Currently, the use of agro-industrial waste represents a viable alternative for obtaining valuable compounds that, in the case of biorefineries, is an opportunity for improvement. In this context, the aim of our study was to determine the flavonoid content and the antioxidant capacity of 30 byproducts from fruit processing in Colombia and propose possible applications. We analyzed the antioxidant capacity of the ethanolic extracts from each byproduct using the ferric reducing antioxidant power (FRAP) and the reducing power of antioxidant activity (RPAA) assays, as well as the oxygen radical absorbance capacity (ORAC) test. We found that tree tomato peels and stem and peach peels had a high flavonoid content, with values greater than 8,271.82 ± 702.70 μg quercetin per gram of dry sample. We also found that mango (22,676.57 ± 759.71 μg TE1/g Sdb, 3,692.38 ± 92.67 μg GAE/g Sdb), soursop (22,117.13 ± 754.94 μg TE1/g Sdb, 4,858.79 ± 156.71 μg GAE/g Sdb, 14,713.39 ± 757.95 μg TE2/g Sdb), grape (17,027.85 ± 765.11 μg TE1/g Sdb, 13,395.15 ± 659.31 μg TE2/g Sdb), peach peels (17,910.21 ± 1,424.33 μg TE2/g Sdb) and seeds (4,316.46 ± 112.00 μg GAE/g Sdb, 20,093.32 ± 1,317.93 μg TE2/g Sdb), and grape stalk (3,552.26 ± 31.63 μg GAE/g Sdb) showed a high antioxidant capacity in the different tests performed. Our results demonstrate that fruit byproducts have potential use in the pharmaceutical, ood, and cosmetic industry due to heir flavonoids content and their high antioxidant capacity.

Tree Tomato

Solanum betaceum is a tree from the Andean region bearing edible fruits, considered an exotic export. Although there has been renewed interest in its commercialization, sustainability, and disease management have been limiting factors. Phytophthora betacei is a recently described species that causes late blight in S. betaceum. There is no general study of the response of S. betaceum, particularly, in the changes in expression of pathogenesis-related genes. In this manuscript we present a comprehensive RNA-seq time-series study of the plant response to the infection of P. betacei. Following six time points of infection, the differentially expressed genes (DEGs) involved in the defense by the plant were contextualized in a sequential manner. We documented 5,628 DEGs across all time-points. From 6 to 24 h post-inoculation, we highlighted DEGs involved in the recognition of the pathogen by the likely activation of pattern-triggered immunity (PTI) genes. We also describe the possible effect of the pathogen effectors in the host during the effector-triggered response. Finally, we reveal genes related to the susceptible outcome of the interaction caused by the onset of necrotrophy and the sharp transcriptional changes as a response to the pathogen. This is the first report of the transcriptome of the tree tomato in response to the newly described pathogen P. betacei.
