BGS 43, Multiovary 1, mov1
Stock number: BGS 43
Locus name: Multiovary 1
Locus symbol: mov1
Previous nomenclature and gene symbolization:
Multiovary 5 = mo5 (5).
Multiovary 6 = mo6b (3, 4).
Inheritance:
Monofactorial recessive (3).
Located in chromosome 7HL (3, 4); mov1.f is near the Amy2 (Alpha-amylase 2) locus (3); mov1.f co-segregated with molecular markers Hsp17 and JS192.5 in 7H bin 07 (4); the plant of Bowman backcross-derived line for mov1.f, BW523, tested with SNP markers did not have the mov1.f allele, but it is present in the stock (1).
Description:
The mov1.f (mov6b) mutant has four carpels and two sepal-like structures where the lodicules should be. Stamens and lodicules are absent. It is presumed that the three stamens found in wild-type flowers have been converted into three additional carpels and that the lodicules have become leaf-like structures (4). The mov1.f plants appear normal, but are completely sterile. The stock must be maintained as a heterozygote (2). This mutant appears morphologically similar to the mo5 mutant (5), which was reported to map to the same region of chromosome 7HL (6). A seed stock was, however, not available for allelism tests (4).

Origin of mutant:
A fast neutron induced mutant in Steptoe (CIho 15229) (3).
Mutational events:
mov1.f (mo6b, FN01, GSHO 3641) in Steptoe (CIho 15229) (2); mov1.e (mo5) (4, 5); mov1.i (5102, mo6c), mov1.j (5103, mo6d) from the Institute of Plant Genetics and Crop Plant Research, Gatersleben, Germany (4).
Mutant used for description and seed stocks:
mov1.f (mo6b, FN01, GSHO 3641) in Steptoe; mov1.f from Steptoe in Bowman (PI 483237)*4 (BW523, NGB 22158).
