Structural changes, chemical composition and antioxidant activity of cherry tomato fruits (cv. Micro‐Tom) stored under optimal and chilling conditions

Abstract

BACKGROUND: Cherry tomato fruits cv. Micro-Tom, a model plant for tomato genetics, were analysed in order to determine the main structural and chemical changes under optimal and chilling storage conditions. The comparison of Micro-Tom to standard tomato cultivars will give an insight into suitability of this dwarf cultivar as a model for studying the influence of low-temperature conditions on tomato fruits.

Effect of prolonged root hypoxia on the antioxidant content of tomato fruit

“…3 also presents the accumulation kinetic in pericarp of fruits of the major carotenoids. Consistent with previous results [53,54], the lycopene content of control fruit pericarp increased progressively to reach a maximum concentration of 1 mg g −1 DW at the RR stage. At the same stage, the concentration of ␤-carotene was doubled in the pericarp of control fruits.…”

Enhancement of phytosterols, taraxasterol and induction of extracellular pathogenesis-related proteins in cell cultures of Solanum lycopersicum cv Micro-Tom elicited with cyclodextrins and methyl jasmonate

“…MT tomato is currently being used for plant genetic (Meissner et al, 1997;Martí et al, 2006), genomic (Dan et al, 2006;Aoki et al, 2010), and physiological and developmental studies (Martí et al, 2006;Gómez et al, 2009).…”

Magnetic resonance imaging provides spatial resolution of Chilling Injury in Micro-Tom tomato (Solanum lycopersicum L.) fruit

“…Its high-density growth, short life cycle and concentrated fruit-set (i.e., many fruit of a similar age) makes it possible to obtain harvests of 500 fruit or more per square meter per year (Meissner et al, 1997). Because tomato postharvest studies can be hampered by biological variability (Hertog et al, 2004), the availability of numerous, similarly aged fruit makes Micro-Tom a convenient experimental model for postharvest studies (Gomez et al, 2009;Luengwilai et al, 2012a,b;Malacrida et al, 2006;Re et al, 2012;Sorrequieta et al, 2013;VegaGarcia et al, 2010;Weiss and Egea-Cortines, 2009). Furthermore, we have previously characterized Micro-Tom fruit physiological response to a range of postharvest chilling temperature-time combinations (Luengwilai et al, 2012a), and used this information to design a metabolomics investigation of CI (Luengwilai et al, 2012b).…”
