BGS 622, Calcaroides-e, cal-e

BGN  32:123
Stock number: BGS 622
Locus name: Calcaroides-e
Locus symbol: cal-e

Previous nomenclature and gene symbolization:



Monofactorial recessive (2).
Located in chromosome 5HS (3); cal-e.23 is about 23 cM distal from AFLP marker E3432-2, which is proximal from molecular marker WG889 in 5H bin 06 (3).


At the tip of the lemma proper, in a position corresponding to the transition between lemma and awn, the cal-e mutant has a distinctive ectopic structure, which includes a sac, sac appendages, and awn wings (3). The cal-e mutant bears a short distal awn. In contrast to the Kap1 (hooded lemma 1) phenotype, the sac does not develop into an epiphyllous flower (3).

Origin of mutant:

A sodium azide induced mutant in Semira (NGB 10716) (1, 2).

Mutational events:

cal-e.23 (NGB 119382) in Semira (NGB 10716) (2).

Mutant used for description and seed stocks:

cal-e.23 (NGB 119382) in Semira.
