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).


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).


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).
