Extensin network formation in Vitis vinifera callus cells is an essential and causal event in rapid and H₂O₂-induced reduction in primary cell wall hydration

BMC Plant Biology, 2011
Background Extensin deposition is considered important for the correct assembly and biophysical properties of primary cell walls, with consequences to plant resistance to pathogens, tissue morphology, cell adhesion and extension growth. However, evidence

Comparative transcriptomics analysis reveals differential Cd response processes in roots of two turnip landraces with different Cd accumulation capacities

Ecotoxicology and Environmental Safety, 2021
Understanding the molecular mechanisms of cadmium (Cd) tolerance and accumulation in plants is important to address Cd pollution. In the present study, we performed comparative transcriptome analysis to identify the Cd response processes in the roots of ...

The lncRNA APOLO and the transcription factor WRKY42 target common cell wall EXTENSIN encoding genes to trigger root hair cell elongation

Plant Signalling & Behavior, 2021
Plant long noncoding RNAs (lncRNAs) are key chromatin dynamics regulators, directing the transcriptional programs driving a wide variety of developmental outputs.

Proline-rich Extensin-like Receptor Kinases PERK5 and PERK12 are involved in Pollen Tube Growth

bioRxiv, 2021
Background Cell wall integrity plays an essential role during polarized cell growth typical of pollen tubes and root hairs. Proline-rich Extensin-like Receptor Kinases (PERK) belong to the hydroxyproline-rich glycoprotein (HRGP) superfamily of cell ...

Cell wall O-glycoproteins and N-glycoproteins: biosynthesis and some functional aspects.

Frontiers in Plant Science, 2014
Cell wall O-glycoproteins and N-glycoproteins are two types of glycomolecules whose glycans are structurally complex. They are both assembled and modified within the endomembrane system, i.e., the endoplasmic reticulum (ER) and the Golgi apparatus ...

Isolation and Characterization of Three Soybean Extensin cDNAs [PDF]

Plant Physiology, 1994
We have characterized three different soybean (Glycine max) mRNAs that encode apoproteins of extensins, a family of cell wall hydroxyproline-rich glycoproteins (HRGPs). These transcripts encoded distinctive Tyr-rich proteins containing characteristic Ser-Pro4 sequences organized in higher-order repetitive units. The first transcript encoded an extensin

Investigations into the molecular size and shape of tomato extensin [PDF]

Biochemical Journal, 1996
The molecular characteristics of soluble extensin from tomato have been investigated. An apparent molecular mass greater than 240 kDa has been previously observed with the shape-dependent method of gel-filtration chromatography [Brownleader and Dey (1993) Planta (Berlin) 191, 457–469].

The reinforcement of potato cell wall as part of the phosphite-induced tolerance to UV-B radiation

Biologia Plantarum, 2018
Phosphites (Phis), inorganic salts of phosphorous acid, have shown to be effective in protection of plants against biotic stress. Recently, we have described that potassium phosphite (KPhi) induces tolerance to UV-B radiation in potato. To counteract the

Construction of Transgenic Pea Lines with Modified Expression of Diamine Oxidase and Modified Nodulation Responses with Exogenous Putrescine

Molecular Plant-Microbe Interactions, 2000
Diamine oxidase (DAO) might influence pea nodule development either by regulating the peroxide-driven cross-linking of glycoproteins in the infection thread matrix or by modifying the metabolism of diamines and polyamines in host cells. Transformed lines

The Role of Carbohydrate in Maintaining Extensin in an Extended Conformation [PDF]

Plant Physiology, 1986
Monomers of the plant cell wall glycoprotein extensin are secreted into the wall where they become cross-linked to each other to form a rigid matrix. Expression of the extensin matrix is correlated with the inhibition of further cell elongation during normal development, with increased resistance to virulent pathogens and with other physiological ...
