BGS 626, Scirpoides leaf-a, scl-a

BGN  44:201
Stock number: BGS 626
Locus name: Scirpoides leaf-a
Locus symbol: scl-a

Previous nomenclature and gene symbolization:

Scirpoides leaf-6 = scl.6 (3).
Scirpoides leaf-1 = scl.1 (3).
Scirpoides leaf-2 = scl.2 (3).
Scirpoides leaf-4 = scl.4 (3).

Inheritance:

Monofactorial recessive (2).
Located in chromosome 1HL (1), scl-a.6 is associated with SNP markers 1_0433 to 1_0396 (positions 139.25 to 143.47 cM) in 1HL in Bowman backcross-derived line BW778; scl-a.6 is associated with SNP marker 2_0780 (position 154.89 cM) in 1HL in Bowman backcross-derived line BW775; associated with SNP markers 1_0006 and 2_1126 (position 110.10 cM) in 1HL in Bowman backcross-derived line BW776 (1), likely in 1H bin 11.

Description:

Leaf blades of scl-a plants are folded inward and are narrow compared to those of normal sibs. Folding of the leaf blade persists until maturity (2, 3). Plants of Bowman backcross-derived line BW778 were slightly shorter than Bowman, kernels were slightly thinner and lighter, and grain yields were about 20% lower. Plants of BW778 have inward folded leaf blades that are about 2/3 as wide as those of Bowman (2). The mutant stocks scl.1, scl.2, and scl.4 are alleles based on allelism tests (2). Their phenotypic similarities to the scl-a.6 mutant and SNP markers retained in the same region of 1HL suggesting they are alleles at the scl-a locus (1, 2).

Origin of mutant:

A neutron induced mutant in Foma (NGB 14659, CIho 11333) (3).

Mutational events:

scl-a.6 (NGB 117105) in Foma (NGB 14659, CIho 11333) (3); scl-a.1 (NGB 117100), scl-a.2 (NGB 117101), scl-a.4 (NGB 117102) in Bonus (NGB 14657, PI 189763) (1, 2, 3).

Mutant used for description and seed stocks:

scl-a.6 (NGB 117105) in Foma; scl-a.6 in Bowman (PI 483237)*5 (GSHO 3431), in Bowman*6 (BW778, NGB 20755); scl-a.1 in Bonus (NGB 117100), in Bowman*4 (BW774, NGB 22242); scl-a.2 in Bonus (NGB 117101), in Bowman*5 (BW775, NGB 22243); scl-a.4 in Bonus (NGB 117102), in Bowman*5 (BW776, NGB 20753).
