Plant Physiology, 2022 Callose is a plant cell wall polysaccharide whose deposition is spatiotemporally regulated in various developmental processes and environmental stress responses. The appearance of callose in premeiotic anthers is a prominent histological hallmark for the

A plant NLR receptor activates auxin signaling through Aux/IAAs-ARF19 and YUC8-TIR1/AFBs to promote callose-mediated antiviral defense. [PDF]
Sci AdvPhytohormone signaling pathways are crucial for defense against pathogens mediated by pattern recognition receptors and nucleotide-binding leucine-rich repeat (NLR) immune receptors.

, 2013 Localized cell wall thickenings, so called papillae, are a common plant defense response to fungal attack at sites of penetration of the plant cell. The major constituent of papillae is callose, a (1,3)-β-glucan polymer, which contributes to slowing or

Biochemical and Cytological Interactions Between Callose Synthase and Microtubules in the Tobacco Pollen Tube [PDF]
Plant Cell Reports, 2021 Abstract Callose is a cell wall polysaccharide involved in several fundamental biological processes, ranging from plant development to response to abiotic and biotic stresses. To understand how callose deposition is regulated, it is important to know how its synthesizing enzyme, i.e., callose synthase, is regulated and if it interacts ...

Expression Analysis of Genes for Callose Synthases and Rho-Type Small GTP-Binding Proteins That Are Related to Callose Synthesis in Rice Anther [PDF]
Bioscience, Biotechnology, and Biochemistry, 2006 The most chilling-sensitive stage of rice has been found to be at the onset of microspore release. The microsporocytes produce a wall of callose between the primary cell wall and the plasma membrane, and it has been shown that precise regulation of callose synthesis and degradation in anther is essential for fertile pollen formation.

An Arabidopsis Callose Synthase, GSL5, Is Required for Wound and Papillary Callose Formation [PDF]
The Plant Cell, 2003 Arabidopsis was transformed with double-stranded RNA interference (dsRNAi) constructs designed to silence three putative callose synthase genes: GLUCAN SYNTHASE-LIKE5 (GSL5), GSL6, and GSL11. Both wound callose and papillary callose were absent in lines transformed with GSL5 dsRNAi and in a corresponding sequence-indexed GSL5 T-DNA insertion line but ...

Stimulation of Callose Synthesis in Vivo Correlates with Changes in Intracellular Distribution of the Callose Synthase Activator [beta]-Furfuryl-[beta]-Glucoside [PDF]
Plant Physiology, 1993 [beta]-Furfuryl-[beta]-glucoside (FG) has been shown to be a specific endogenous activator of higher plant callose synthase (P. Ohana, D.P. Delmer, G. Volman, J.C. Steffens, D.E. Matthews, M. Benziman [1992] Plant Physiol 98: 708-715). Because glycosides such as FG are usually sequestered in vacuoles, we have proposed that activation of callose ...

Genome-wide analysis of the CalS gene family in cotton reveals their potential roles in fiber development and responses to stress [PDF]
PeerJ, 2021 Callose deposition occurs during plant growth and development, as well as when plants are under biotic and abiotic stress. Callose synthase is a key enzyme for the synthesis of callose.

The function and biosynthesis of callose in high plants
Heliyon, 2022 The two main glucan polymers cellulose and callose in plant cell wall are synthesized at the plasma membrane by cellulose or callose synthase complexes. Cellulose is the prevalent glucan in cell wall and provides strength to the walls to support directed
