Introduction.

AX depolymerization products obtained by endo-xylanase (EC 3.2.1.8)-catalyzed hydrolysis are denoted arabinoxylan-oligosaccharides.Following previously described criteria (), the present paper uses the following acronyms: XOS for xylooligosaccharides, AXOS for arabino-xylooligosaccharides, (A)XOS for mixtures of XOS and AXOS, and (A)XOS as well for unspecified products of AX depolymerization. Arabinoxylan is a dietary fiber found in cereal grains such as wheat, corn, rice, rye, oat, and barley. It is used as a medicine. Arabinoxylan is taken by mouth for heart disease, constipation Arabinoxylan is the main group of hemicellulosic polysaccharides that are present in the cell walls of monocot grass crops and hence in cereal grains. The arabinoxylan polysaccharides consist of a backbone of β-(1→4)-linked xylopyranosyl residues, which carry arabinofuranosyl moieties, hence the term arabinoxylan. Arabinoxylan Oligosaccharides With Different DP Trigger Calcium Influxes in Arabidopsis In order to investigate whether pentose-based structures could be sensed by Arabidopsis, we decided to analyze in a first instance the capacity to trigger Ca 2+ influxes of different commercial polymeric structures ( Figure 2A ).
