Genetic control of dinitroaniline resistance in foxtail millet (Setaria italica)
Article Abstract:
Populations of two generations of crosses between a resistant green foxtail and three foxtail millet cultivars show that a recessive gene provides resistance to dinitroaniline in foxtail millet. The resistance is also apparently influenced by a few more minor genes. F(sub 2) generation of the cross yields an average 15% resistance in seedlings, while selection for resistance results in 100% resistant F(sub 3) generations. This shows that the resistant seedlings are homozygous for recessive factors. The resistance is assessed by the absence of inhibition of root growth in seedlings in the presence of trifluralin, a dinitroaniline herbicide.

Genetic analysis of variegated mutants in Arabidopsis
Article Abstract:
VAR1, VAR2 and VAR4 are Arabidopsis thaliana variegated mutants produced by recessive mutations in nuclear chromosomes. Genetic analysis of the second filial generation from reciprocal crosses involving normal and mutant plants reveal that a mutation of the allele var1-1 at locus Var1 produced the VAR1 variegation. Mutations of the alleles var2-1 and var2-2 at the Var2 locus resulted in VAR2 and VAR4 variegation respectively. Linkage studies show that Var1 and Var2 are found in chromosomes 5 and 2 respectively. VAR1 exhibit temperature sensitivity while VAR2 and VAR4 exhibit light sensitivity.

Isolation and genetic analysis of a triazolopyrimidine-resistant mutant of Arabidopsis
Article Abstract:
A nuclear gene mutation afforded ethyl methyl sulfonate treated seeds of Arabidopsis thaliana resistance to triazolopyrimidine. The mutation is found in linkage group 3 and occurred at an allele of the gene for acetolactate synthase (ALS). Mutant plants are 500 times as resistant to triazolopyrimidine and their ALSs were 1,000 times as resistant to triazolopyrimidine inhibition compared to the wild type. These two phenotypes are the result of the same mutation as the traits cosegregated.
