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 ...

A signaling pathway mediating abscisic acid‐induced jasmonic acid biosynthesis during strawberry ripening

Journal of Integrative Plant Biology, EarlyView.
During strawberry ripening, abscisic acid signaling activates SnRK2.6, which phosphorylates and degrades the JAZ12 repressor. This releases the MYC2 transcription factor, directly activating jasmonic acid biosynthesis genes. The resulting jasmonic acid accumulation drives aroma production, thereby coupling ripening with scent formation through this ...

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.

Root tip excision‐induced exodermis lignification impacts lateral root emergence in Brachypodium distachyon

New Phytologist, EarlyView.
Summary The mechanisms controlling lateral root emergence in monocots, particularly the role of the exodermis, are poorly understood. We investigated how natural variation in the Brachypodium distachyon stress response shapes root system architecture by modulating cell wall dynamics.

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 ...

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.

Quiescence of postharvest pathogens: a fungal inhibition process or an immune response of the unripe host fruit?

New Phytologist, EarlyView.
Summary Postharvest pathogens can infect fresh produce both before and after harvest, by direct or wound‐enhanced penetration, remaining quiescent until ripening. Biotrophic‐like postharvest pathogens persist beneath host cells and can remain in a state of quiescence.

Characterization of a Ralstonia solanacearum Operon Required for Polygalacturonate Degradation and Uptake of Galacturonic Acid

Molecular Plant-Microbe Interactions, 2003
The bacterial wilt pathogen Ralstonia solanacearum produces three extracellular polygalacturonases (PGs): PehA, PehB, and PehC. All three PGs hydrolyze pectin's polygalacturonic acid backbone, but each releases different reaction products.
