ZmMS39 encodes a callose synthase essential for male fertility in maize (Zea mays L.)
Callose contributes to many biological processes of higher plants including pollen development, cell plate and vascular tissue formation, as well as regulating the transport function of plasmodesmata. The functions of callose synthase genes in maize have

Regulation of callose synthase activity
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 ...

The effect of silicon supplementation and drought stress on the deposition of callose and chemical components in the cell walls of the Brassica napus roots [PDF]
Background Silicon has an important role in regulating water management in plants. It is deposited in cell walls and creates a mechanical barrier against external factors.

Developmental evolution of flowering plant pollen tube cell walls: callose synthase (
Background A number of innovations underlie the origin of rapid reproductive cycles in angiosperms. A critical early step involved the modification of an ancestrally short and slow-growing pollen tube for faster and longer distance transport of sperm to ...

Biochemical and cytological interactions between callose synthase and microtubules in the tobacco pollen tube. [PDF]
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 ...

Defense-related callose synthase PMR4 promotes root hair callose deposition and adaptation to phosphate deficiency in Arabidopsis thaliana. [PDF]
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.

Characterization of Callose Deposition and Analysis of the Callose Synthase Gene Family of Brassica napus in Response to Leptosphaeria maculans. [PDF]
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.

Genome-wide analysis of the CalS gene family in cotton reveals their potential roles in fiber development and responses to stress [PDF]
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 maize callose synthase SLM1 is critical for a normal growth by controlling the vascular development. [PDF]
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.
