Polygalacturonase in tree pollens [PDF]

open access: yesPhytochemistry, 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 ...

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

open access: yesPlant 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.

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

open access: yesPlant 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.

A review of the postharvest biochemical, biophysical and biological properties of 61 cultivars of North American pawpaw (Asimina triloba) fruit

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 1968-1980, 15 March 2026.
Abstract Fruit from the North American pawpaw (Asimina triloba) is unfamiliar to many as a food crop and botanically unusual because it is the northernmost genus and only temperate member of the tropical Annonaceae family. It is the largest edible fruit native to North America.

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]

open access: yes, 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.

Polygalacturonase and Polygalacturonase Inhibitor Protein: Gene Isolation and Transcription in Glycine max - Heterodera glycines Interactions [PDF]

open access: yesMolecular 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

Transcriptomic prey‐capture responses in convergently evolved carnivorous pitcher plants

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2559-2573, March 2026.
Summary The Australian pitcher plant Cephalotus and the Asian pitcher plant Nepenthes exhibit striking morphological and functional similarities, serving as compelling examples of convergent evolution. Although trapping pitchers in both lineages represent some of the most elaborate leaf structures in angiosperms, it remains unknown whether their ...

Dual‐Role GH7 Family Proteins From Verticillium dahliae Function as Virulence Factors and Intracellular Effectors Triggering NLR‐Mediated Immunity

open access: yesPlant, Cell &Environment, Volume 49, Issue 3, Page 1491-1504, March 2026.
ABSTRACT Cell wall–degrading enzymes are viewed as extracellular virulence factors. However, their potential to act as immune elicitors and interact with intracellular immune receptors remains poorly defined. Here, we demonstrate that six conserved glycoside hydrolase 7 (GH7) family proteins from the fungal pathogen Verticillium dahliae have dual roles

Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.
