Preharvest supplemental lighting enhances productivity and modulates postharvest quality in hydroponically grown Apulian unripe melon ‘Scopatizzo’ (Cucumis melo L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Preharvest light management is increasingly used to enhance yield and fruit quality in soilless systems, yet its effects on unripe melon fruits remain poorly understood. This study evaluated the impact of supplemental red–blue light‐emitting diode (LED) lighting applied during cultivation in a closed‐cycle hydroponic system on ...

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 cloning of tomato fruit polygalacturonase: Analysis of polygalacturonase mRNA levels during ripening [PDF]

Proceedings of the National Academy of Sciences, 1986
The expression of a gene encoding the cell wall-degrading enzyme polygalacturonase [poly(1,4-α-D-galacturonide) glucanohydrolase, EC 3.2.1.15] was characterized during tomato fruit ripening. Polygalacturonase was purified from ripe tomato fruit and used to produce highly specific antiserum.

The multidimensional regulation roles and mechanisms of calcium in fruit quality

Journal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

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.

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.

Identification of Genetic Loci Conveying Resistance to Fusarium oxysporum f. sp. ciceris Race 0 in Chickpea

Plant Breeding, EarlyView.
ABSTRACT Chickpea (Cicer arietinum L.) is a legume that is widely consumed around the world due to its nutritional content. Fusarium oxysporum f. sp. ciceris is a serious, destructive pathogen that causes fusarium wilt disease and affects chickpea production.

Genetic dissection of southern corn leaf blight resistance in sweet corn through genome‐wide association studies and genomic selection

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Southern corn leaf blight (SCLB) is caused by the fungal pathogen Bipolaris maydis (syn. Cochliobolus heterostrophus Drechsler) and is a common disease of fall crops of sweet corn. Phenotyping for SCLB resistance is performed through visual scoring, which is subjective and may limit genetic gain for this quantitative trait.

Black flesh disorder in mango: a chilling injury symptom increased by early harvest and low storage temperature and reduced by 1‐methylcyclopropene

Journal of the Science of Food and Agriculture, Volume 106, Issue 11, Page 6508-6522, 30 August 2026.
Abstract BACKGROUND Black flesh (BF) is an internal disorder in mango, characterized by the development of dark brown to black pigmentation in the inner mesocarp tissue during storage or transport. This study investigated the effects of harvest maturity, low storage or low transport temperatures, and 1‐methylcyclopropene (1‐MCP) on mango fruit ...

From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance

Advanced Science, Volume 13, Issue 39, 13 July 2026.
Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...
