BGS 68, Purple veined lemma 1, Pvc1
Stock number: BGS 68
Locus name: Purple veined lemma 1
Locus symbol: Pvc1
Previous nomenclature and gene symbolization:
Purple veined lemma = C (1).
Purple veined lemma = Pc (1).
Monofactorial dominant (4), but Buckley suggested that three pairs of genes controlled expression of purple pigmentation of lemma veins (1).
Located in chromosome 2HL (1, 4); Pvc1.a is about 22.2 cM distal from the vrs1 (six-rowed spike 1) locus (1); the Bowman backcross-derived line for Pvc1.a, BW651, did not retain any SNP markers polymorphisms compared to Bowman (2).
Purple pigment is produced by the presence of anthocyanins. When Pvc1 is expressed, purple pigmentation of the kernel is confined mainly to the lemma veins (1). The pigments are formed late during grain fill when the lemma is exposed to sunlight, and they tend to fade as the spike matures (3). The Bowman backcross-derived line for Pvc1.a, BW651, had slightly heavier kernel and showed a slight increase in grain yield compared to Bowman (3).
Origin of mutant:
Natural occurrence in some cultivars and in some Hordeum vulgare subsp spontaneum accessions.
Pvc1.a (GSHO 132) in Buckley 2223-6 (1).
Mutant used for description and seed stocks:
Pvc1.a (GSHO 132) in Buckley 2223-6; Pvc1.a from R.I. Wolfe's Multiple Dominant Stock (GSHO 1565) in Bowman (PI 483237)*7 (GSHO 1929, BW 651, NGB 22216).
