Engineered Production of Hydroxycinnamoyl Tyramine Conjugates Limits the Growth of the Pathogen Pseudomonas syringae in Arabidopsis

Plant, Cell &Environment, EarlyView.
ABSTRACT Hydroxycinnamoyl tyramine conjugates are phenolamides produced by plants in response to pathogen attack and biotic stresses. Their proposed mechanisms of action include cytotoxicity towards pathogens, cell wall reinforcement to restrict pathogen proliferation, and signaling activity to trigger general stress responses.

Identification of Callose Synthases in Stinging Nettle and Analysis of Their Expression in Different Tissues

International Journal of Molecular Sciences, 2020
Callose is an important biopolymer of β-1,3-linked glucose units involved in different phases of plant development, reproduction and response to external stimuli. It is synthesized by glycosyltransferases (GTs) known as callose synthases (CalS) belonging to family 48 in the Carbohydrate-Active enZymes (CAZymes) database.

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

Plant 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.

Absence of Cu–Zn superoxide dismutase BCSOD1 reduces Botrytiscinerea virulence in Arabidopsis and tomato plants, revealinginterplay among reactive oxygen species, callose and signallingpathways [PDF]

, 2017
Plants activate responses against pathogens, including the oxida-tive burst. Necrotrophic pathogens can produce reactive oxygenspecies (ROS) that benefit the colonization process.

ABA Is Required for Leptosphaeria maculans Resistance via ABI1- and ABI4-Dependent Signaling

Molecular Plant-Microbe Interactions, 2007
Abscisic acid (ABA) is a defense hormone with influence on callose-dependent and -independent resistance against Leptosphaeria maculans acting in the RLM1Col pathway.

Intrusive growth of sclerenchyma fibers [PDF]

, 2010
Intrusive growth is a type of cell elongation when the rate of its longitudinal growth is higher than that of surrounding cells; therefore, these cells intrude between the neighboring cells penetrating the middle lamella.

Decoding plant defense signaling using the defenseless mutant

New Phytologist, Volume 250, Issue 2, Page 1141-1156, April 2026.
Summary Can plants live without defenses? Mutant analysis in Arabidopsis thaliana has identified numerous regulators of biotic, abiotic, and hormone‐based defenses, but the redundancy among separate defense pathways remains unexplored. We constructed an Arabidopsis mutant, defenseless, lacking six canonical defense pathways using abi1‐1 (abscisic acid),

TaRIP2 Positively Regulates Wheat Pollen Wall Formation Through MYB80‐Controlled Lipid Metabolism

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2595-2606, April 2026.
ABSTRACT Male‐sterile genes and mutants are critical for hybrid seed production in monocotyledonous crops. Lipids are essential structural components of male reproductive organs, such as the anther and pollen. Here, we show that the pollen‐preferential gene TaRIP2 is essential for wheat anther development and pollen formation. RT‐qPCR analysis revealed

Genes involved in barley yellow dwarf virus resistance of maize [PDF]

, 2014
KEY MESSAGE: The results of our study suggest that genes involved in general resistance mechanisms of plants contribute to variation of BYDV resistance in maize. ABSTRACT: With increasing winter temperatures in Europe, Barley yellow dwarf virus (BYDV) is
