Modeling of the break process to improve tomato paste production quality : a thesis presented in partial fulfilment for the degree of Master of Engineering in Bioprocess at Massey University [PDF]

, 2002
The pectic enzyme, Pectinmethylesterase (PE) and Polygalacturonase I and II (PGI and PGII), in the tomato fruit released after crushing during tomato processing reduce the viscosity of tomato paste by breaking down the insoluble pectin in the cell wall ...

Composition and Action of Yeast Polygalacturonase [PDF]

Nature, 1954
YEAST polygalacturonase is an exo-cellular pectic enzyme produced by Saccharomyces fragilis in a synthetic, protein-free medium. The enzyme is constitutive and is not accompanied by pectinesterase1. When it is allowed to act on pectic acid, the following series of reactions occurs2: (a) Pectic acid → penta- + tetra- + tri- + digalacturonic acids; (b ...

Bioconversion of carotenoids into high‐value crocins using a marine sponge carotenoid cleavage dioxygenase

New Phytologist, EarlyView.
Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

CpERF‐WRI1 Manipulates Ethylene Sensing by Regulating the Expression of CpERS1 and Fruit Ripening in Papaya

Plant Biotechnology Journal, EarlyView.
ABSTRACT Ethylene plays a crucial role in fruit ripening and is perceived by specialised receptor proteins embedded in the endoplasmic reticulum (ER) membrane. As an ethylene antagonist, 1‐methylcyclopropene (1‐MCP) binds to these receptors and delays papaya ripening, but improper use can cause ripening disorders.

Safety evaluation of the food enzyme endo‐polygalacturonase from the genetically modified Aspergillus oryzae strain AR‐183

EFSA Journal, 2023
The food enzyme endo‐polygalacturonase (1→4)‐α‐d‐galacturonan glycanohydrolase EC 3.2.1.15 is produced with the genetically modified Aspergillus oryzae strain AR‐183 by AB ENZYMES GmbH. The genetic modifications do not give rise to safety concerns.

Beyond Starch: Towards a Scalable Potato Platform for Molecular Farming

Plant Biotechnology Journal, EarlyView.
Re‐engineering potato as a biosafe and host‐optimised platform for plant molecular farming by integrating intrinsic biological traits with targeted engineering strategies. ABSTRACT Thirty‐five years after the first recombinant protein was produced in potato and 30 years after clinical trials of edible vaccines from its tubers, the crop is being ...

Effect of Trichoderma viride on activities of polygalacturonase of Rhizoctonia

浙江大学学报. 农业与生命科学版, 2004
The pectin is a backbone of the plant cell wall, its network structure will systemicly resolve when the plant cell splits up and forms. The pectinase produced by Rhizoctonia mainly acts on the pectin of cell wall, and causes the maceration of tissue and ...

Molecular analysis of the early interaction between the grapevine flower and Botrytis cinerea reveals that prompt activation of specific host pathways leads to fungus quiescence [PDF]

, 2017
Grape quality and yield can be impaired by bunch rot, caused by the necrotrophic fungus Botrytis cinerea. Infection often occurs at flowering, and the pathogen stays quiescent until fruit maturity.

Ripening-Related Polygalacturonase cDNA from Avocado [PDF]

Plant Physiology, 1993
During the ripening of avocado (Persea americana) fruit, extensive cell wall degradation leads to a dramatic softening of the mesocarp tissue. Two enzymes have been suggested to play a critica1 role in this ripening-associated cell wall degradation in many fruits, including avocado, viz.

Assessing the adaptive potential of European beech populations to temperature and precipitation along a steep environmental gradient in the south‐eastern Carpathians

Plant Biology, EarlyView.
This study focuses on the identification of candidate SNPs involved in local adaptation to altitude by environmental association analysis conducted on different natural European beech (Fagus sylvatica) populations. Abstract It is necessary to assess the adaptive potential of European beech populations to climate change.
