An Antisense Pectin Methylesterase Gene Alters Pectin Chemistry and Soluble Solids in Tomato Fruit.
Pectin methylesterase (PME, EC 3.1.11) demethoxylates pectins and is believed to be involved in degradation of pectic cell wall components by polygalacturonase in ripening tomato fruit. We have introduced antisense and sense chimeric PME genes into tomato to elucidate the role of PME in fruit development and ripening. Fruits from transgenic plants expressing high levels of antisense PME RNA sho...
متن کاملAnalysis of spatially resolved hyperspectral scattering images for assessing apple fruit firmness and soluble solids content
Hyperspectral scattering is a promising technique for nondestructive sensing of multiple quality attributes of apple fruit. This research evaluated nd compared different mathematical models for describing the hyperspectral scattering profiles over the spectral region between 450 nm and 000 nm in order to select an optimal model for predicting fruit firmness and soluble solids content (SSC) of ‘...
متن کاملMultispectral imaging for predicting firmness and soluble solids content of apple fruit
Firmness and soluble solids content (SSC) are important quality attributes for apples and many other fresh fruits. This research investigated the feasibility of using multispectral imaging to quantify light backscattering profiles from apple fruit for predicting firmness and SSC. Spectral images of the backscattering of light at the fruit surface, which were generated from a focused broadband b...
متن کاملTomato Fruit Quality and Content Depend on Stage of Maturity
Soluble solids (Brix), carbohydrate, organic acid, lycopene, polyphenols and HMF content of indeterminate round type tomato Lemance F1 fruits were measured in six ripeness stages from mature green to deep red stage. Color of fruits was determined by CIELab system. The L*, a*, b* values were received directly and used to calculate from which the a*/b* ratio was calculated. The Brix, carbohydrate...
متن کاملIn vitro synthesis and processing of tomato fruit polygalacturonase.
The in vitro processing of tomato fruit polygalacturonase (PG) (poly[1,4-alpha-d-galacturonide]glucanohydrolase, EC 3.2.1.15) was studied. Complete chemical deglycosylation of a mixture of mature, purified PG 2A and PG 2B isozymes (45 and 46 kilodaltons; respectively) with trifluoromethane sulfonic acid yielded a single polypeptide of 42 kilodaltons. Similarly, N-terminal amino acid sequencing ...
