The mutagenic effects of diepoxybutane in wild-type and mutagen-sensitive mutants of Drosophila melanogaster.

Genetic tests reported here demonstrate that among the DEB-induced mutants on 2 X-chromosome loci, viz. y and w, at a minimum, one-third are chromosome deletions. Among 11 MMS-sensitive mutants tested, 9 are also somatically sensitive to DEB. In addition direct genetic tests established that the capacity to repair DEB damage induced in sperm is impaired in females homozygous for 2 mutagen-sensitive mutants. By inference the same is also the case in females homozygous for 3 other mutagen-sensitive mutants.

Plant ADP-glucose pyrophosphorylase--recent advances and biotechnological perspectives (a review).

Recent advances in studies on plant ADP-glucose pyrophosphorylase (AGP), the key enzyme of starch biosynthesis, are presented. AGP constitutes the first committed and highly regulated step of starch synthesis in all plant tissues. The importance of AGP in carbohydrate metabolism and several of its features, such as potent regulation by cellular effectors (3-phosphoglycerate and Pi), an unusual two subunit-types structure, tissue-specific and developmentally-regulated expression, and presence of the AGP-deficient mutants, make it an attractive, but complex, target for biotechnological manipulations. Some strategies for future research on AGP are discussed.
