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.

Polygalacturonase in tree pollens [PDF]
Phytochemistry, 1991 Abstract The pollens from 38 species of trees were analysed for polygalacturonase activity. All of the pollens contained polygalacturonase but the range of activities was great. Eastern cottonwood pollen contained the most polygalacturonase, with a level about 12 times higher than that usually found in ripe tomato fruit, which has been the highest ...

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.Cell wall‐degrading enzymes of Cytospora chrysosperma play a crucial role in the infection process. Kmt3 directly regulates Lac11 expression via H3K36me3, thereby influencing laccase activity and affecting C. chrysosperma's degradation of lignocellulose. ABSTRACT Woody canker diseases cause devastating timber losses worldwide. Canker fungi exploit cell

Polygalacturonase and Polygalacturonase Inhibitor Protein: Gene Isolation and Transcription in Glycine max - Heterodera glycines Interactions [PDF]
Molecular Plant-Microbe Interactions®, 1999 The cell wall acts as the first line of defense during pathogen invasion. Polygalacturonases (PGs) are a class of cell-wall-modifying enzymes with precise temporal and organ-specific expression. A 350-bp fragment with high homology to PGs was identified by differential display (DD) analysis of soybean cyst nematode (SCN) race 3 resistant PI 437654 and

New Phytologist, Volume 250, Issue 2, Page 812-821, April 2026.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.

Nanostructural differences in pectic polymers isolated from strawberry fruits with low expression levels of pectate lyase or polygalacturonase genes [PDF]
, 2013 Our research group has obtained transgenic strawberry plants expressing antisense sequences of either a pectate lyase (APEL lines) [1] or a polygalacturonase gene (APG lines) [2].
