BGS 43, Multiovary 1, mov1

BGN  43:59
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).


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).


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).
