Frontiers in Plant Science, 2018 Cell wall reinforcement with callose is a frequent plant response to infection. Poly(ADP-ribosyl)ation is a protein post-translational modification mediated by poly(ADP-ribose) polymerases (PARPs).

BMC Plant Biology, 2018 Background Plant cell walls are mainly composed of polysaccharides such as cellulose and callose. Callose exists at a very low level in the cell wall; however, it plays critical roles at different stages of plant development as well as in defence against

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.

Frontiers in Plant Science, 2018 Plasmodesmata are channels that link adjacent cells in plant tissues through which molecular exchanges take place. They are involved in multiple processes vital to plant cells, such as responses to hormonal signaling or environmental challenges including

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.

Cellulose biosynthesis in higher plants
Acta Societatis Botanicorum Poloniae, 2014 Knowledge of the control and regulation of cellulose synthesis is fundamental to an understanding of plant development since cellulose is the primary structural component of plant cell walls.

Molecular and biochemical studies of cellulose and callose synthase [PDF]
, 2002 Cotton fibers consist of almost pure cellulose in the secondary wall stage. To isolate a cellulose synthase gene from cotton, the catalytic region of cellulose synthase in Aceobacter xylinum was used to search the EST database.

Glucan synthase of Phytophthora sojae [PDF]
, 2002 Glucans, with the (1-3)-b-glucosidic linkage as major feature, are present in most of the higher plants, in many lower plants, as well as in microorganisms (Stone and Clarke, 1992). The synthesis of (1-3)-b-glucan in vivo is catalysed by the enzyme (1-3)-

A Cell Plate-Specific Callose Synthase and Its Interaction with Phragmoplastin
The Plant Cell, 2001 Abstract Callose is synthesized on the forming cell plate and several other locations in the plant. We cloned an Arabidopsis cDNA encoding a callose synthase (CalS1) catalytic subunit. The CalS1 gene comprises 42 exons with 41 introns and is transcribed into a 6.0-kb mRNA. The deduced peptide, with an approximate molecular mass of 226 kD,
