Somatic hybrids between the cultivated potato Solanum tuberosum L. and the 1EBN wild species Solanum pinnatisectum Dun.: morphological and molecular characterization.

Interspecific somatic hybrids between the 1EBN-wild species Solanum pinnatisectum (S. pnt) and four different diploid breeding lines of Solanum tuberosum (S. tbr) were produced by electrofusion.

A specific oligonucleotide of the 5S rDNA spacer and species-specific elements identify symmetric somatic hybrids between Solanum tuberosum and S. pinnatisectum.

The nucleotide sequences of the 5S rRNA genes (5S rDNA) of two Solanum tuberosum breeding lines (R1 and B15) and of the Mexican wild species S. pinnatisectum were determined and compared with each other and to the 5S rDNA of other Solanaceae species (Lycopersicon esculentum, Nicotiana rustica and Petunia hybrida). The 5S rDNA repeats of the Solanum species are 324-329 bp in length, and they exhibit 91-95% sequence identity.

[Treatment of depressed patients: current trends. Combination cognitive group therapy with cognitive adjustment for depressed inpatients].

Depressed patients represent a major part of the inpatient population. The following treatment program was developed in order to respond to this problem in a symptom- and cost-effective way. Cognitive therapy was chosen for it's learning aspect and combined with pharmacotherapy.
