The rob (Hordeum) Gene
Gene Class : Orange lemma base and node
|
|
Rob normal phenotype (dominant)
|
rob orange phenotype (recessive)
|
Description:
The lemma, palea, and rachis have an
orange pigmentation that is present in immature spikes, can be observed at
heading, and is retained in
mature grain and spikes. The orange pigmentation is visible at the base
of the sheath of seedlings
and in exposed nodes after jointing. Internodes have a layer of orange
tissue and stems
have an orange color as
the straw dries. The mutant stock for rob1.f (OUM189) has
a lighter
orange lemma color than that in other mutants at the rob locus.
