Abstract: DNA sequence of S-genes which encode S-proteins and control the self-incompatibility reaction in gametophytic self-incompatible plants have been identified. The DNA sequence encoding several S-proteins of N. alata and their attendant signal sequences are specifically provided. Regulatory sequences which direct expression of the S-genes in reproduction tissue of self-incompatible plants have also been identified. A method for the identification and isolation of cDNA and genomic DNA coding sequences of the S-genes is described.

Abstract: A lubricating oil composition containing as essential ingredients a lubricating oil component having a melting point of not higher than 100.degree. C., and one or more water-soluble dispersants selected from the group consisting of anionic polymeric dispersants of a molecular weight of 250 to 25,000, and polyoxyethylene type surfactants of a molecular weight of 3,000 to 20,000 and an HLB value of at least 18, said lubricating oil component being present in a stably dispersed state in water, achieves excellent adhesion when supplied to a machined portion.

Abstract: The invention concerns novel and useful mutant microbes which are capable of releasing substantial amounts of any of several periplasmic or recombinant proteins into the culture medium when carrying an expressed Kil gene. Though E. coli are exemplified, the invention is broadly applicable to the making of mutants of other microbes, for example, Salmonella, Klebsiella, and Rhizobium. A key feature of the invention is the use of a novel selection procedure employing a plasmid comprising the kil gene.

Abstract: An aryl N,N'-bis cinnamamide compound having a formula comprising: ##STR1## wherein x equals an integer from 0 to 3; y equals an integer from 0 to 2; z equals an integer from 0 to 2; each R is individually selected from the group consisting of a lower alkyl group having 1 to 4 carbon atoms, a lower alkoxy group having from 1 to 4 carbon atoms, a halo group, a nitro group, an aryl group having 6 to 18 carbon atoms, and a fused unsubstituted or substituted aromatic ring when x is 2 or 3; and each R' and R" is individually selected from the group consisting of a lower alkyl group having from 1 to 4 carbon atoms, a lower alkoxy group having from 1 to 4 carbon atoms, a halo group, a nitro group or an aryl group having from 6 to 18 carbon atoms. These compounds are useful as U.V. light absorbers in plastics and cosmetics (e.g. sunscreens).

Abstract: Compounds having the formula ##STR1## are prepared from a corresponding o-nitrophenol by blocking the hydroxyl groups via acetal formation, followed by reductive coupling and acid hydrolysis.

Abstract: Compounds of the formula ##SPC1##WhereinA is 1,4-naphthylene, substituted 1,4-naphthylene, 1,4-(5,6,7,8-tetrahydronaphthylene) or substituted 1,4-(5,6,7,8-tetrahydronaphthylene), wherein each substituent of substituted 1,4-naphthylene and substituted 1,4-(5,6,7,8-tetrahydronaphthylene) is independently lower alkyl, lower alkoxy or halo,D is sulfophenyl or substituted sulfophenyl wherein each substituent is independently lower alkyl, lower alkoxy, nitro or halo,Each R is independently lower alkyl, andn is 0 to 2,And mixtures thereof, are useful for dyeing and printing natural polyamides such as wool and silk, synthetic polyamides such as nylon, polyacrylonitrile, acrylonitrile copolymers and polyvinyl alcohol on which they build-up well. The dyeings are fast to light and wet treatments.
