Linkage tests of gracile axonal dystrophy (gad), an autosomal neurological mutation in the mouse, have shown that gad was located on chromosome 5 and linked to Pgm-1 and W. On the basis of the backcross data, the following recombination frequencies were calculated: Pgm-1-gad, 3.0±1.0 percent; W-gad, 5.4±2.6 percent. Therefore, the gene order was estimated to be centromere-gad-Pgm-1-W. Since Pgm-1 was closely linked to gad, Pgm-1 is a useful marker to recognize homozygotes (gad/gad) before onset of clinical signs and detect carriers (gad/+).

The mutagenic activity of cobalt (II) chloride (CoCl₂) was examined using the Salmonella test system in the presence of quinoline compounds. CoCl₂, which itself is non-mutagenic, exhibited mutagenicity when combined with quinoline, 2-methylquinoline, 3-methylquinoline, 4-methylquinoline, 6-methylquinoline, 7-methylquinoline, 2-aminoquinoline, 4-aminoquinoline and 8- aminoquinoline in strains TA1537 and TA2637. Mixtures of CoCl₂ and 8- methylquinoline, 3-aminoquinoline or 5-aminoquinoline did not induce mutations. The combined mutagenicity may be due to a formation of complexes between the Co(II) cation and quinoline compounds judging from the spectral data.

Somatic clones doubly homozygous for Antp^w10 and Rg-bx mutations were induced with X-ray and examined for the cuticular morphology of these clones covering the antenna. The Antp^- Rg-bx^- clones on the antenna show nearly normal arista together with bristles of the leg type on the basal cylinder and the third antennal segment whereas the Rg-bx^- clones transform the distal antennal tissue to the tarsal segments of the leg. The absence of the Rg-bx⁺ function is suggested to cause the hypermorphic expression of the Antp locus in the antennal tissue.

A DNA fragment possessing ORF12 of TL-DNA of Ri(A4) plasmids (Slightom et al. 1986) was inserted into the genome of Nicotiana tabacum cv. Petite Havana SR1, through the binary vector system harbored by Agrobacterium tumefaciens. The transformed plants showed dwarfness in plant height and corolla length. Adventitious roots were not induced from leaf disks by A. tumefaciens possessing ORF12.
