Mutant Name: mur2

Gene Name MUR2
Protein Name fucosyltransferase(xyloglucan)
Mutagen EMS
Category forward genetics
Organism Arabidopsis
Ecotype Col
Donor
General Description mur2 plants show a normal growth habit and wall strength
Organ Specificity The mur2 mutation eliminates xyloglucan fucosylation in all major plant organs.
Impact on Wall Cell walls of the Arabidopsis mutant mur2 contain less than 2% of the wild-type amount of fucosylated xyloglucan
Impact on Sugar Composition The mur2 mutant has a 50% reduction in the levels of fucose, but nearly complete loss of fucose from xyloglucan.
