Biochemical and cytological interactions between callose synthase and microtubules in the tobacco pollen tube [PDF]
Plant Cell Reports, 2022 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 ...

Regulation of callose synthase activity
BMC Plant Biology, 2009 Background The cell wall component callose is mainly synthesized at certain developmental stages and after wounding or pathogen attack. Callose synthases are membrane-bound enzymes that have been relatively well characterized in vitro using isolated ...

Evolutionary history of callose synthases in terrestrial plants with emphasis on proteins involved in male gametophyte development. [PDF]
PLoS ONE, 2017 Callose is a plant-specific polysaccharide (β-1,3-glucan) playing an important role in angiosperms in many developmental processes and responses to biotic and abiotic stresses.

Xanthomonas Type III Effector XopN Targets Scaffold Protein OsRACK1B to Suppress Rice Immunity. [PDF]
Mol Plant PatholDuring infection, XopN is translocated into host cells and competes with OsRap2.6 for binding to OsRACK1B. This competitive interaction interferes with the formation of the OsRACK1B–OsRap2.6 subcomplex, thereby weakening plant resistance. ABSTRACT Bacterial leaf streak (BLS), caused by Xanthomonas oryzae pv.

Genomic and Transcriptomic Analyses Provide Insights Into Erysiphe necator Pathogenicity and Grapevine Response. [PDF]
Plant Biotechnol JABSTRACT Grapevine powdery mildew, caused by the fungus Erysiphe necator, is one of the most prevalent obligate biotrophic pathogens in vineyards, posing a significant threat to grape production. Despite its impact, research on E. necator pathogenicity and grapevine responses remains limited.

Role of callose synthases in transfer cell wall development in tocopherol deficient Arabidopsis mutants [PDF]
Frontiers in Plant Science, 2014 Tocopherols (vitamin E) are lipid-soluble antioxidants produced by all plants and algae, and many cyanobacteria, yet their functions in these photosynthetic organisms are still not fully understood.

Characterization of Callose Deposition and Analysis of the Callose Synthase Gene Family of Brassica napus in Response to Leptosphaeria maculans. [PDF]
Int J Mol Sci, 2018 Callose plays a critical role in different biological processes including development as well as in the response to multiple biotic and abiotic stresses. In this study, we characterized the callose deposition in cotyledons of different Brassica napus varieties post-inoculated with different Leptosphaeria maculans isolates.

The maize callose synthase SLM1 is critical for a normal growth by controlling the vascular development. [PDF]
Mol Breed, 2023 Callose, mainly deposited at the cell plate and in the newly formed cell wall at a very low level, is critical for cell activity and growth in plants. The genetic control and function of callose synthases, responsible for the synthesis of callose, are largely unknown in maize.

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.

Defense-related callose synthase PMR4 promotes root hair callose deposition and adaptation to phosphate deficiency in Arabidopsis thaliana. [PDF]
Plant J, 2023 SUMMARYPlants acquire phosphorus (P) primarily as inorganic phosphate (Pi) from the soil. Under Pi deficiency, plants induce an array of physiological and morphological responses, termed phosphate starvation response (PSR), thereby increasing Pi acquisition and use efficiency.
