Screening for female-sterile mutants

Isolation and Characterization of Sex-Linked Female-Sterile Mutants in DROSOPHILA MELANOGASTER with Special Attention to Eggshell Mutants.

To study genes that function mainly or exclusively during oogenesis, we have isolated and analyzed female-sterile mutations, with special emphasis on those that affect eggshell formation. Following treatment that induced 61 to 66% lethals, 8.1% of the 1071 X chromosomes tested carried recessive female sterility mutations (87 isolates), and 8.0% carried partial female-sterile mutations (86 isola...

Isolation and characterization of sex-linked female-sterile mutants in Drosophila melanogaster.

The purpose of the experiments described was to identify X chromosome genes functioning mainly or exclusively during oogenesis. Two mutagenesis experiments were carried out with ethyl methane sulfonate. Following treatment inducing 60% lethals, 9% of the treated X chromosomes carried a female sterility mutation which did not otherwise seriously affect viability. Among--95 isolated mutants, 19 w...

Genetic identification of a female partial-sterile mutant in soybean.

We report here the genetic identification of a female partial-sterile mutant derived from soybean mutant L67-3483. L67-3483, which originated from the cultivar Clark after X-ray irradiation, is male and female fertile. All F1 plants in reciprocal pollinations of L67-3483 with 'Clark', 'Minsoy', or 'BSR 101' were female partial sterile. Partial sterility is expressed in the heterozygous conditio...

Screening for gene regulation mutants by bioluminescence imaging.

Because plants cannot move, they have evolved complex sensing and response systems to cope with the physical environment. Adverse environmental conditions, such as those causing abiotic stress, often cause significant losses in crop productivity and quality. Because of a paucity of well-defined visible phenotypes, conventional genetic screens have not been very successful in isolating abiotic s...
