BGS 36, Xantha seedling 4, xnt4
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).
Xantha seedling c2 = xc2 (3).
Inheritance:
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).
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).
Description:
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.
