Characteristics of persons 60 years of age and older in Linn County, Iowa

Early in 1957, 695 persons 60 years of age or older were interviewed in Linn County, Iowa. This group was randomly selected from the population of such persons residing in the county. In attempting to draw generalizations for the population of senior persons of Linn County from the survey, the following comments appear appropriate. The majority of this age group were well adjusted, considering themselves a part of the community and expressing little desire to change their present mode of life. A majority preferred to live in their own homes in their present community rather than in homes or accommodations restricted to aged persons. Not surprisingly, if persons were asked to describe the type of accommodations they would consider the most desirable for the age group, they described arrangements similar to their present living arrangements.https://lib.dr.iastate.edu/specialreports/1026/thumbnail.jp

The potato developer (D) locus encodes an R2R3 MYB transcription factor that regulates expression of multiple anthocyanin structural genes in tuber skin

A dominant allele at the D locus (also known as I in diploid potato) is required for the synthesis of red and purple anthocyanin pigments in tuber skin. It has previously been reported that D maps to a region of chromosome 10 that harbors one or more homologs of Petuniaan2, an R2R3 MYB transcription factor that coordinately regulates the expression of multiple anthocyanin biosynthetic genes in the floral limb. To test whether D acts similarly in tuber skin, RT-PCR was used to evaluate the expression of flavanone 3-hydroxylase (f3h), dihydroflavonol 4-reductase (dfr) and flavonoid 3′,5′-hydroxylase (f3′5′h). All three genes were expressed in the periderm of red- and purple-skinned clones, while dfr and f3′5′h were not expressed, and f3h was only weakly expressed, in white-skinned clones. A potato cDNA clone with similarity to an2 was isolated from an expression library prepared from red tuber skin, and an assay developed to distinguish the two alleles of this gene in a diploid potato clone known to be heterozygous Dd. One allele was observed to cosegregate with pigmented skin in an F1 population of 136 individuals. This allele was expressed in tuber skin of red- and purple-colored progeny, but not in white tubers, while other parental alleles were not expressed in white or colored tubers. The allele was placed under the control of a doubled 35S promoter and transformed into the light red-colored cultivar Désirée, the white-skinned cultivar Bintje, and two white diploid clones known to lack the functional allele of D. Transformants accumulated pigment in tuber skin, as well as in other tissues, including young foliage, flower petals, and tuber flesh

Crime Does Not Pay But Taxpayers Do

In an average year close to 3,000 lawless Iowa citizens pass in our penal institutions. All of these people are tried in court; and after conviction the county sheriff transports them to their respective institutions. The traffic is never ending.</p
