Molecular diversity of citrus genotypes using callose synthase 7 gene markers linked to Huanglongbing resistance

Jurnal Agronomi Indonesia (Indonesian Journal of Agronomy)
Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus, is a notable disease affecting citrus plantations globally. Several studies showed that the callose synthase 7 gene is crucial for the citrus defense system against this pathogen.

Callose and Callose Synthase

1992
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 ...

Localization of sucrose synthase and callose in freeze-substituted secondary-wall-stage cotton fibers

Protoplasma, 2003
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

Expression of callose synthase genes and its connection with Npr1 signaling pathway during pathogen infection

Planta, 2008
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 ...

Membrane fractionation and enrichment of callose synthase from pollen tubes of Nicotiana alata Link et Otto

Planta, 1998
The callose synthase (UDP-glucose: 1,3-beta-D-glucan 3-beta-D-glucosyl transferase; EC 2.4.1.34) enzyme (CalS) from pollen tubes of Nicotiana alata Link et Otto is responsible for developmentally regulated deposition of the cell wall polysaccharide callose. Membrane preparations from N.

Plasmolysis treatment enhances the expression of callose synthase gene in zygotic embryos of Eleutherococcus senticosus

Journal of Forestry Research, 2010
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.

Biochemical evidence linking a putative callose synthase gene with (1→3)-β-d-glucan biosynthesis in barley

Plant Molecular Biology, 2003
A putative barley (1 --> 3)-beta-D-glucan synthase cDNA of 6.1 kb, which is homologous to the yeast FKS gene, was assembled from DNA fragments obtained through screening of barley cDNA and BAC libraries, and by PCR amplification. The corresponding gene, designated HvGSL1, is a member of a family of at least six genes in barley.

Translation Co-factor PABP-interacting protein 11 moonlights as a transcriptional activator to modulate callose synthesis gene expression.

The Plant Journal
The development of rice fertility is a complex process, which is precisely regulated by numerous genes. In this study, we cloned and characterized OsPAIP11, a PABP-interacting protein that functions as an auxiliary factor in translation initiation.

APP1/NTL9-CalS8 module ensures proper phloem differentiation by stabilizing callose accumulation and symplastic communication.

New Phytologist
Phloem sieve elements (PSE), the primary conduits collaborating with neighboring phloem pole pericycle (PPP) cells to facilitate unloading in Arabidopsis roots, undergo a series of developmental stages before achieving maturation and functionality ...

Callose Deficiency Modulates Plasmodesmata Frequency and Extracellular Distance in Rice Pollen Mother and Tapetal cells.

Annals of Botany
Fertilization relies on pollen mother cells able to transit from mitosis to meiosis to supply gametes. This process involves remarkable changes at the molecular, cellular and physiological levels including (but not limited to) remodelling of the cell ...
