    Notizen: Summary Mitochondrial DNA from etiolated seedling of male-fertile (F) and male-sterile (S) sunflower (Helianthus annuus L.) has been investigated for the first time in an isogenic couple HA89. 1. The mt-DNAs isolated from the S and F cytoplasms give a sharp and symmetrical band at 1.706 g/ml in an analytical CsCI gradient ultracentrifugation. 2. In polyacrylamide gel it is found that mitochondria from F cytoplasm contain a Low-Molecular-Weight (LMW) mt-DNA molecule of 1.45 Kilobase-pairs (kb) in addition to the major mt-DNA. On the contrary, mitochondria from S cytoplasm contain no LMW molecule. Treatments with DNAse, RNAse and Nuclease S1 show that this LMW mt-DNA molecule consists of a supercoiled circular DNA. The length and form of the LMW molecule are confirmed by electron microscopy observations. 3. The mt-DNAs from S and F cytoplasms have also been investigated using restriction endonuclease digestions (Sa11, Xho1, Bg11). The electrophoresis of the resulting fragments reveals several differences between the S and F cytoplasm. It is not known whether the differences observed between F and S mt-DNA are correlated with the cytoplasmic male sterility phenotype.

    Beschreibung: Recent work on workspace monitoring allows conflict prediction early in the development process, however, these approaches mostly use syntactic differencing techniques to compare different program versions. In contrast, traditional change-impact analysis techniques analyze related versions of the program only after the code has been checked into the master repository. We propose a novel approach, DeCAF (Development Context Analysis Framework), that leverages the development context to scope a change impact analysis technique. The goal is to characterize the impact of each developer on other developers in the team. There are various client applications such as task prioritization, early conflict detection, and providing advice on testing that can benefit from such a characterization. The DeCAF framework leverages information from the development context to bound the iDiSE change impact analysis technique to analyze only the parts of the code base that are of interest. Bounding the analysis can enable DeCAF to efficiently compute the impact of changes using a combination of program dependence and symbolic execution based approaches.
