PYK10/BGLU23 is a beta-glucosidase that is a major protein of ER bodies, which are endoplasmic reticulum (ER)-derived organelles that may be involved in defense systems. PYK10 has active and inactive forms. Active PYK10 molecules form large complexes with diameters ranging from 0.65 microm to > 70

Lipopolysaccharide (LPS) is an amphiphatic bacterial glycoconjugate found on the external membrane of Gram-negative bacteria. This endotoxin is considered as a microbe-associated molecular pattern (MAMP) molecule and has been shown to elicit defense responses in plants. Here, LPS-interacting

Jacalin-related lectins (JRLs) are a subgroup of proteins with one or more jacalin-like lectin domains. Although JRLs are often associated with biotic or abiotic stimuli, their biological functions in plants, as well as their relationships to plant disease resistance, are poorly understood. A

Jacalin-related lectins (JRLs) are carbohydrate-binding proteins widely present in plants and have one or more jacalin domains in common. However, JRLs' structural types and functions are still poorly understood. In the present study, a total of 67 wheat (Triticum aestivum) JRL genes were identified

Lectins selectively recognize sugars or glycans for defense in living cells, but less is known about their roles in the development process and the functional network with other factors. Here, we show that Arabidopsis (Arabidopsis thaliana) JACALIN-LECTIN LIKE1 (AtJAC1) functions in flowering time

The ER body is an endoplasmic reticulum (ER)-derived organelle. Because ER bodies are induced by wounding and methyl jasmonate (MeJA) treatment in rosette leaves, they might be responsible for defense systems. Recently, we isolated nai1 mutants that have no ER body and showed that the levels of

Restriction of long-distance movement of several potyviruses in Arabidopsis (Arabidopsis thaliana) is controlled by at least three dominant restricted TEV movement (RTM) genes, named RTM1, RTM2, and RTM3. RTM1 encodes a protein belonging to the jacalin family, and RTM2 encodes a protein that has

Understanding the innate immune mechanisms of plants is necessary for breeding of disease-resistant lines. Previously, we identified the antiviral resistance gene JAX1 from Arabidopsis thaliana, which inhibits infection by potexviruses. JAX1 encodes a unique jacalin-type lectin protein. In this

The locus RTM1 is necessary for restriction of long-distance movement of tobacco etch virus in Arabidopsis thaliana without causing a hypersensitive response or inducing systemic acquired resistance. The RTM1 gene was isolated by map-based cloning. The deduced gene product is similar to the

Gene duplication provides large numbers of new genes that can lead to the evolution of new functions. Duplicated genes can diverge by changes in sequences, expression patterns, and functions. MicroRNAs play an important role in the regulation of gene expression in many eukaryotes. After duplication,

Plants possess a multilayered defense response, known as plant innate immunity, to infection by a wide variety of pathogens. Lectins, sugar binding proteins, play essential roles in the innate immunity of animal cells, but the role of lectins in plant defense is not clear. This study analyzed the

Restriction of long distance movement of several potyviruses in Arabidopsis thaliana is controlled by at least three dominant restricted TEV movement (RTM) genes, named RTM1, RTM2 and RTM3 and acts as a non conventional resistance. RTM1 encodes a protein belonging to the jacalin family and RTM2

Glucosinolates are a group of thioglucosides that are components of an activated chemical defense found in the Brassicales. Plant tissue damage results in hydrolysis of glucosinolates by endogenous thioglucosidases known as myrosinases. Spontaneous rearrangement of the aglucone yields reactive
