Abstract Over the past century numerous cytochemical studies have shown that after various types of stress the polysaccharide callose is deposited, at selected sites, on to the plant cell wall. Callose mainly consists of linear 13-1, 3-glucanase (1-4), and one of its functions is to close the connections that unite protoplasts of ...

Arabidopsis callose synthases CalS1/8 regulate plasmodesmal permeability during stress
Nature Plants, 2016Plants need to cope with biotic and abiotic stress through well-coordinated cell-to-cell communication to survive as sedentary organisms. Environmental challenges such as wounding, low temperature, oxidative states and pathogen infection are known to affect the symplasmic molecular exchange between plant cells determined by plasmodesmal permeability ...

In previous study we reported that pretreatment with plasmolysis enhanced somatic embryo formation in hypocotyls of Eleutherococcus senticosus. In the present study, the expression level of callose synthase gene in embryos of E. senticosus in response to 2,4-D, sucrose and mannitol treatments was analyzed by RT-PCR.

Methods for cryogenic fixation, freeze substitution, and embedding were developed to preserve the cellular structure and protein localization of secondary-wall-stage cotton (Gossypium hirsutum L.) fibers accurately for the first time. Perturbation by specimen handling was minimized by freezing fibers still attached to a seed fragment within 2 min after

Callose synthesis occurs at specific stages of plant cell wall development in all cell types, and in response to pathogen attack, wounding and physiological stresses. We determined the expression pattern of "upstream regulatory sequence" of 12 Arabidopsis callose synthase genes (CalS1-12) genes and demonstrated that different callose synthases are ...

Abstract The resistance of the first true leaf of cucumber to Colletotrichum lagenarium was increased by infecting the cotyledon or the tip of the first leaf with C. lagenarium or tobacco necrosis virus. Microsomes and plasma membranes, prepared from first leaves in which resistance was induced, exhibited increased specific activity of the Ca2 ...
