Gene Details:

• Gene ID: Zm00001eb025100
• Gene Symbol: RTH6
• Gene Name: roothairless 6
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Root hairs of the monogenic recessive maize mutant roothairless 6 (RTH6) are arrested after bulge formation during the transition to tip growth and display a rough cell surface.
• Phylogenetic analyses revealed that RTH6 is part of a monocot specific clade of D-type cellulose synthases.
• RTH6 gene of maize which encodes CSLD5, a monocot and root hair-specific D-type cellulose synthase required for the transition from bulge formation to tip growth in root hair formation.
• The transmembrane protein RTH6 is arranged in rosettes and synthesizes cellulose at the plasma membrane47 which is extruded to the inner side of the cell wall in the root hair tip and thus reinforces the tubular shaft.
• In addition to the strong knock down of RTH6 expression in young primary roots of the mutant RTH6, the gene is also significantly down-regulated in rth3 and rth5 mutants, while it is up-regulated in rth2 mutants, suggesting that these genes interact in cell wall biosynthesis.
