Expression Quantitative Trait Loci (eQTL) mapping for callose synthases in intergeneric hybrids of Citrus challenged with the bacteria Candidatus Liberibacter asiaticus [PDF]

Genetics and Molecular Biology, 2020
Citrus plants have been extremely affected by Huanglongbing (HLB) worldwide, causing economic losses. HLB disease causes disorders in citrus plants, leading to callose deposition in the phloem vessel sieve plates.

Cotton fiber annexins: a potential role in the regulation of callose synthase [PDF]

The Plant Journal, 1993
SummaryCotton fibers contain a characteristic set of proteins which interact with plasma membranes in a Ca2+‐dependent manner. The association of these proteins with the membrane is correlated with a reduced level of UDP‐glucose: (1→3)‐β‐glucan (callose) synthase activity.

The plasmodesmal protein PDLP1 localises to haustoria-associated membranes during downy mildew infection and regulates callose deposition [PDF]

, 2014
The downy mildew pathogen Hyaloperonospora arabidopsidis (Hpa) is a filamentous oomycete that invades plant cells via sophisticated but poorly understood structures called haustoria.

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 ...

Brassinosteroids Positively Regulate Plant Immunity via BRI1-EMS-SUPPRESSOR 1-Mediated GLUCAN SYNTHASE-LIKE 8 Transcription

Frontiers in Plant Science, 2022
Plant hormone brassinosteroids (BRs) play key roles in plant adaptation to biotic stresses, including various pathogen infections. As a core factor in BR signaling, the transcription factor BRI1-EMS-SUPPRESSOR 1 (BES1) activates BR responses via ...

Analysis of a novel mutant allele of GSL8 reveals its key roles in cytokinesis and symplastic trafficking in Arabidopsis

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

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.

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.

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.

ROS-mediated plasmodesmal regulation requires a network of an Arabidopsis receptor-like kinase, calmodulin-like proteins, and callose synthases

Frontiers in Plant Science, 2023
Plasmodesmata (PD) play a critical role in symplasmic communication, coordinating plant activities related to growth & development, and environmental stress responses. Most developmental and environmental stress signals induce reactive oxygen species
