Cell wall mechanics and growth control in plants: the role of pectins revisited

Frontiers in Plant Science, 2012
How is the extensibility of growing plant cell walls regulated ? In the past, most studies have focused on the role of the cellulose/xyloglucan network and the enigmatic wall-loosening agents expansins.

Lactose derivatives as potential inhibitors of pectin methylesterases

International Journal of Biological Macromolecules, 2019
The discovery of molecules that can inhibit the action of phytopathogens is essential to find alternative to current pesticides. Pectin methylesterases (PME), enzymes that fine-tune the degree of methylesterification of plant cell wall pectins, play a key role in the pathogenicity of fungi or bacteria.

Cucumber green mottle mosaic virus: A persistent seed‐borne threat to cucurbits

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Cucumber green mottle mosaic virus (CGMMV) is a highly stable, seed‐borne tobamovirus that threatens global cucurbit production. Its efficient mechanical and seed transmission, long‐term environmental persistence, and the spread of Clade II CGMMV isolates drive its rapid dissemination and cause severe yield losses.

Identification of Pectin Methylesterase and Its Inhibitory Subfamily Genes, and Functional Analysis of CsPME55 in Response to Fluoride Stress in Camellia sinensis [PDF]

Chaye kexue
Tea plant (Camellia sinensis) has fluoride (F) enrichment characteristics, and F is mainly enriched in the cell wall component pectin. Pectin methylsterase (PME) and its inhibitor PMEI can catalyze the modification of pectin, thereby affecting cell wall ...

FcMAPK4‐phosphorylated FcNOR activates FcERF5 to promote fig fruit softening through activation of FcPG12 expression

Journal of Integrative Plant Biology, Volume 68, Issue 7, Page 2264-2284, July 2026.
In Ficus carica fruit, the MAP kinase FcMAPK4 phosphorylates the NAC transcription factor FcNOR, which cooperates with ethylene response factor FcERF5 to activate the pectin degradation gene FcPG12, thereby promoting rapid softening of fig fruit. ABSTRACT Rapid softening of fig (Ficus carica L.) fruit during ripening leads to extremely short shelf life;

The Early Response to Urea, Nitrate, or Ammonium and Iron Resupply in Tomato Roots Highlights the Induction of FER, bHLHs, UMAMITs, and MATEs

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Depending on the nitrogen (N) form available to roots, plants activate different transcriptional and metabolic pathways; this can consequently translate into differences in the composition and release of root exudates. To address the existing knowledge gap regarding the relationship between the availability of Iron (Fe) and different N forms ...

Multi‐Omics Unveils the Dual‐Life of the Aquatic Plant Potamogeton nodosus

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Heterophylly, characterized by distinct leaf morphologies, is an adaptive strategy evolved by some aquatic plants to cope with the contrasting environments in which they grow. It is shaped by environmental factors and by hormones, particularly abscisic and gibberellic acids.

Chilling Accumulation Shapes Transcriptomic Responses to Warming Exposure During Grapevine Deacclimation

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT During winter, grapevine (Vitis vinifera) bud dormancy and cold hardiness are regulated by complex interactions between chilling accumulation and warm temperature cues. However, the molecular mechanisms underlying physiological transitions during winter remain poorly understood.

Pectin methylesterases regulated by WRKY76 mediate cadmium accumulation and tolerance via demethylesterifying pectin in rice

Cell Reports
Summary: Cadmium (Cd) toxicity poses a serious threat to plant growth and endangers human health via the food chain. The plant cell wall, composed primarily of cellulose, hemicellulose (HC), and pectin, serves as a critical barrier against abiotic ...
