Narrative
Surface wax coating appears to be appears to be absent on the spike, leaf sheath, and stem (wax code - - ++). Concerning the chemical epicuticular wax composition, only traces of the ( )=diketone wax classes and alkan-2-ol containing esters occur in the cer-x mutant in Bonus. Inheritance: Monofactorial recessive. Located in chromosome 6HL, near the centromere, and less than 3.0 cM distal from the rob (orange lemma) locus. Previous nomenclature and gene symbolization: Glossy sheath 4=gs4. Eceriferum-x=cer-x.
