BGS 140, Xantha seedling 8, xnt8

BGN  26:177
Stock number: BGS 140
Locus name: Xantha seedling 8
Locus symbol: xnt8

Previous nomenclature and gene symbolization:

Albino seedling b = alb,,b (1).
Xantha seedling h = xan,,h (2).


Monofactorial recessive (1, 2).
Located in chromosome 3HS (2); xnt8.h is about 2.9 cM from the msg5 (male sterile genetic 5) locus (2).


Seedlings have a yellow color and die at the two to three leaf stage (1). The xnt8.h gene must be maintained as a heterozygous stock. Allelism tests with mutants at the xnt3 (xantha seedling 3) locus, which is present in the same region of chromosome 3H, have not been conducted.

Origin of mutant:

A spontaneous mutant in Carlsberg II (NGB 5085, CIho 10114) (1).

Mutational events:

xnt8.h (GSHO 582) in Carlsberg II (NGB 5085, CIho 10114) (1).

Mutant used for description and seed stocks:

xnt8.h (GSHO 582) in Carlsberg II.
