BGS 36, Xantha seedling 4, xnt4

BGN  26:85
Stock number: BGS 36
Locus name: Xantha seedling 4
Locus symbol: xnt4

Previous nomenclature and gene symbolization:

Yellow seedling (2).
Xantha seedling c2 = xc2 (3).


Monofactorial recessive (2).
Located in chromosome 7HL (1); xnt4.d is over 22.0 cM from the centromere using the translocation stock T1-6a as a tester (1).


Seedlings have a yellow color and die at a two to three leaf stage (2). The xnt4.d gene must be maintained as a heterozygous stock.

Origin of mutant:

A spontaneous mutant in Coast (PI 539103) (2).

Mutational events:

xnt4.d (xc2) (Coast I, GSHO 42) in Coast (PI 539103) (2).

Mutant used for description and seed stocks:

xnt4.d (GSHO 42) in Coast.
