Genomic and expression analysis of glycosyl hydrolase family 35 genes from rice (Oryza sativa L.).
TL;DR: Rice GH35 contains fifteen genes with a diversity of protein sequences, predicted locations and expression and splicing patterns that suggest that OsBgals enzymes may play a variety of roles in metabolism of cell wall polysaccharides, glycoproteins and glycolipids.

Xyloglucan mobilisation and purification of a (XLLG/XLXG) specific β-galactosidase from cotyledons of Copaifera langsdorffii
TL;DR: The β-galactosidase isolated from cotyledons of germinating seeds of Copaifera langsdorffii seems to perform a key role in xyloglucan degradation since it is responsible for the retrieval of a major sterical hindrance for further hydrolysis of the oligosaccharides and therefore essential for completion of xylglucan mobilisation.

5 – Carbohydrate Metabolism: Structural Carbohydrates
TL;DR: The chapter highlights the current efforts that are going on to clarify the links between the chemical structures of plant cell wall carbohydrates, their interactions, cell wall ultrastructural organization, and tissue mechanical and textural properties.

Pepper β-Galactosidase 1 (PBG1) Plays a Significant Role in Fruit Ripening in Bell Pepper (Capsicum annuum)
TL;DR: It appears that the hydrolysis of galactose residues in pectic substances is the first event in the ripening process in bell pepper fruit.

Plant β-galactosidases: Purification by affinity chromatography and properties
TL;DR: β-Galactosidases from seven plants have been extensively purified by affinity chromatography of an ammonium sulphate concentrate of the respective extracts through a column of Lactosyl-Sepharose, showing charge heterogeneity containing from two to 11 enzymically active isoelectric forms.

Structure and function of the primary cell walls of plants.
TL;DR: All glycosyl residues (except the residue at the reducing end of an oligosaccharide, which is called a glycose residue) are glycosidically linked at C-l and this fact is assumed in the notation used, and, thus, C-\ is not mentioned.

Inhibition of 2,4-dichlorophenoxyacetic Acid-stimulated elongation of pea stem segments by a xyloglucan oligosaccharide.
TL;DR: Xyloglucan, isolated from the soluble extracellular polysaccharides of suspension-cultured sycamore (Acer pseudoplatanus) cells, was digested with an endo-beta-1,4-glucanase purified from the culture fluid of Trichoderma viride to inhibit the elongation of etiolated pea stem segments.

Relationship between Promotion of Xyloglucan Metabolism and Induction of Elongation by Indoleacetic Acid
John M. Labavitch,Peter M. Ray +1 more
TL;DR: The results suggest that the changes in xyloglucan reflect the means by which auxin modifies the cell wall to cause elongation.

Cell Wall Storage Carbohydrates in Seeds—Biochemistry of the Seed “Gums” and “Hemicelluloses”
TL;DR: This chapter outlines the structures and occurrence of cell wall storage carbohydrates to give an account of current research on their metabolism and to explore their overall biological significance in the seeds which contain them.

Turnover of cell wall polysaccharides in elongating pea stem segments.
John M. Labavitch,Peter M. Ray +1 more
TL;DR: A highly selective pattern of wall turnover processes with an even more specific influence of auxin is indicated, suggesting that indoleacetic acid induces conversion of wall xyloglucan from insoluble to water-soluble form.
