BGS 226, Revoluted leaf 1, rvl1

BGN  48:110
Stock number: BGS 226
Locus name: Revoluted leaf 1
Locus symbol: rvl1

Previous nomenclature and gene symbolization:

Revoluted leaf = rvl (2).

Inheritance:

Monofactorial recessive (2).
Located in chromosome 1HL (2, 4); rvl1.a is proximal from the trd1 (third outer glume 1) locus, and distal from the abo1 (albino seedling 1) locus (2), rvl1.a is associated with SNP markers 1_0764 to 1_1006 (positions 61.55 to 110.10 cM) in 1H bins 06 to 10 of the Bowman backcross-derived line BW763 (1). BW763 also retained smaller segments of donor parent SNP markers in chromosome arms 1HL, 4HL, 6HL, and 7HL (1).

Description:

Tips of young leaf blades tend to roll into a tube through a counter-clockwise spiral, compared to flat surfaces of the control. Segregates can be scored from the three-leaf stage until near maturity (2). Plants of the Bowman backcross-derived line for rvl1.a (BW763) were 75 to 90% of normal height and peduncle length varied from slightly reduced to 2/3 of normal. Kernel weights of BW763 were slightly lower and grain yields approached normal (3).

Origin of mutant:

An X-ray induced mutant in Hakata 2 (OUJ807, PI 263407) (2).

Mutational events:

rvl1.a (Kmut 103, GSHO 608) in Hakata 2 (OUJ807, PI 263407) (2, 4).

Mutant used for description and seed stocks:

rvl1.a (GSHO 608) in Hakata 2; rvl1.a from Hakata 2 in Bowman (PI 483237, NGB 22812)*1 (GSHO 2319); rvl1.a in Bowman*5 (BW763, NGB 22231).
