Fruit Ripening Phenomena–An Overview
TL;DR: Recent advances in molecular biology have provided a better understanding of the biochemistry of fruit ripening as well as providing a hand for genetic manipulation of the entire ripening process, leading to considerable societal benefits.
Journal ArticleDOI
The chemistry of texture in fruits and vegetables
TL;DR: In this article, the chemistry of the major primary cell wall components, pectins, hemicelluloses and cellulose, under conditions found during the normal handling of fruits and vegetables is discussed.

Cell wall modifications during fruit ripening: when a fruit is not the fruit
TL;DR: A critical review on the current knowledge concerning differences between fruits and cultivars and the need of using other species and more accurate methodologies to investigate general mechanisms and fruit specificities of softening among different fleshy fruits is provided.

Calcium in plant senescence and fruit ripening
TL;DR: Although high external concentrations of calcium are an advantage in reducing the rate of senescence or ripening, it is emphasized that normal cell function requires the maintenance of low concentrations of free calcium in the cell cytosol.

A photometric adaptation of the somogyi method for the determination of glucose
TL;DR: In this paper, the reliability of the various Somogyi-Shaffer-Hartmann (SHH) copper reagents for glucose determination in biological material has been established, which can be accomplished by omission of the iodide and iodate in their preparation, since these interfere with the molybdate color reagents.

The Structure of Plant Cell Walls: III. A Model of the Walls of Suspension-cultured Sycamore Cells Based on the Interconnections of the Macromolecular Components.
TL;DR: Evidence is provided for a covalent connection between the xyloglucan and pectic polysaccharides and the structural protein of the cell wall and a tentative structure of thecell wall is proposed.

The Structure of Plant Cell Walls: I. The Macromolecular Components of the Walls of Suspension-cultured Sycamore Cells with a Detailed Analysis of the Pectic Polysaccharides.
TL;DR: The structures of the pectic polymers (the neutral arabinan, the neutral galactan, and the acidic rhamnogalacturonan) were obtained by methylation analysis of fragments of these polymers which were released from the sycamore walls by the action of a highly purified endopolygalacturonase.
