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. |
