Mangosteen (Garcinia mangostana L.) is known for its delectable taste and contains high amount of xanthones which have been reported to possess anti-cancer, anti-inflammatory and other bioactive properties. However, stage-specific regulation of mangosteen fruit ripening has never been studied in detail. We have performed a comparative transcriptomic analysis of three ripening stages (Stage 0, 2...

Transcript abundance of the gene encoding -galactosidase II, a -galactosidase/exo-galactanase (EC 3.2.1.23) present during tomato (Lycopersicon esculentum) fruit ripening, was suppressed by expression of an antisense tomato -galactosidase 4 (TBG4) cDNA driven by the cauliflower mosaic virus 35S promoter. RNA gel-blot analysis was used to evaluate TBG4 mRNA levels in transgenic fruit. All of the...

Softening and pathogen susceptibility are the major factors limiting the marketing of blueberries as fresh fruits, and these traits are associated with fruit cell wall structure. However, few studies that characterize wall modifications occurring during development and ripening have been reported for this fruit. In this study the ripening-associated modifications of blueberry fruit cell walls (...

Watermelon is a satiating fruit supplemented with health promoting components like sugars, antioxidants mainly lycopene, minerals etc. The biochemical composition, including antioxidants, and the specific activities of enzymes of watermelon fruit of four icebox cultivars were compared at their sequential stages of development and ripening and also an attempt has been made to determine their nut...

The volatile composition of white Agudelo, Blancolexitimo, Godello and red Serradelo cultivars (NW Spain) harvested at two different stages of ripening have been evaluated. C(6)-compounds, alcohols, volatile fatty acids, monoterpenes, C(13)-norisoprenoids, volatile phenols and carbonyl compounds were identified and quantified in free and glycosidically bound forms by gas chromatography-mass spe...

Ribulose-1,5-bisphosphate carboxylase/oxygenase, catalase, glycolate oxidase, and hydroxypyruvate reductase activities on a protein and fresh weight basis were measured over seven stages of tomato fruit development and ripening. Ribulose-1,5-bisphosphate carboxylase decreased steadily during fruit development from 23 +/- 8 nmoles per minute per milligram protein at the mature green stage to 13....

A cDNA clone encoding a putative dihydroflavonol 4-reductase gene has been isolated from a strawberry (Fragaria x ananassa cv Chandler) DNA subtractive library. Northern analysis showed that the corresponding gene is predominantly expressed in fruit, where it is first detected during elongation (green stages) and then declines and sharply increases when the initial fruit ripening events occur, ...
