Isolated T4 phage DNA (sigma=1.694 g/ml) is applied to seedlings of the crucifer Matthiola incana (DNA density sigma=1.698 g/ml). The phage DNA can partly be reextracted from the plants in a specific DNA fraction, which is predominantly characterized by its unusual high density (high density complex=HDC; sigma=1.724 g/ml). DNA:DNA hybridization studies show that phage specific DNA sequences are...
The phycobiliprotein phycoerythrin was localized in symbiotic and free-living Nostoc of the cycad Cycas using immunocytochemistry. In symbiotic Nostoc, phycoerythrin was associated with the thylakoid membranes of vegetative cells and absent from heterocysts. Similar cellular/subcellular localization was observed between symbiotic Nostoc and the free-living Cycas isolate Nostoc 7422.
