Plants use identical inhibitors to protect their cell wall pectin against microbes and insects

Ecology and Evolution, 2020
As fundamentally different as phytopathogenic microbes and herbivorous insects are, they enjoy plant‐based diets. Hence, they encounter similar challenges to acquire nutrients. Both microbes and beetles possess polygalacturonases (PGs) that hydrolyze the

Safety evaluation of a food enzyme containing endo-polygalacturonase, pectinesterase and pectin lyase activities from the non-genetically modified <i>Aspergillus niger</i> strain CCTCC M 2023236. [PDF]

EFSA J
Abstract The food enzyme containing endo‐polygalacturonase (1,4‐α‐d‐galacturonan glycanohydrolase; EC 3.2.1.15), pectinesterase (pectin pectylhydrolase; EC 3.1.1.11) and pectin lyase (1,4‐6‐O‐methyl‐α‐d‐galacturonan lyase; EC 4.2.2.10) activities is produced with the non‐genetically modified Aspergillus niger strain CCTCC M 2023236 by Suntaq ...

Assessing the adaptive potential of European beech populations to temperature and precipitation along a steep environmental gradient in the south-eastern Carpathians. [PDF]

Plant Biol (Stuttg)
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.

Identification and Structural Elucidation of Galloylated B-Type Procyanidins From Rumex obtusifolius L. Using Enzymatic Digestion, Phloroglucinolysis, and High-Resolution Mass Spectrometry. [PDF]

J Sep Sci
ABSTRACT Procyanidins from plant extracts demonstrate a broad spectrum of bioactive potential. In order to establish structure‐activity relationships, it is necessary to fully determine the stereochemistry and substitution pattern. Phloroglucinolysis and nuclear magnetic resonance (NMR) are conventionally employed for the analysis of galloylated B‐type

Inhibition of an extracellular polygalacturonase from Geotrichum candidum by a proteinaceous inhibitor isolated from lemon fruits [PDF]

, 2017
An extracellular polygalacturonase [EC 3.2.1.15], named PG-543, was purified from the culture of Geotrichum candidum IEV 543, a phytopathogenic fungi isolated from infected lemon.

ps2, the gene responsible for functional sterility in tomato, due to non-dehiscent anthers, is the result of a mutation in a novel polygalacturonase gene [PDF]

, 2009
The recessive mutation ps-2, which appeared spontaneously in tomato, confers functional male sterility due to non-dehiscent anthers. In this study, we isolated and characterized the PS-2 gene.

Polygalacturonase and xylanase forms produced by Fusarium avenaceum in infected lupin roots and their sensitivity to a cell wall glycoprotein

Acta Agrobotanica, 2013
Using CM-Sepharose column chromatography it was shown that Fusarium avenaceum produced two forms of endo-polygalacturonase, one exo-polygalacturonase and two forms of endo-xylanase in infected Iupin roots.

Toward gentle chokeberry juice production by ultrasound-assisted enzymatic maceration

Current Research in Food Science, 2023
Sustainable processes accompanied by high extraction yields and minimized amounts of by-products are a major goal of current fruit juice production. Controlled degradation of cell wall polysaccharides, in particular pectin, may contribute to reduced ...
