chloroplast phosphofructokinase: i. proof of phosphofructokinase activity in chloroplasts.	ammonium sulfate fractionation of an extract from the leaves of spinach (spinacia oleracea l.) produced two fractions of phosphofructokinase activity, the first stimulated by inorganic phosphate and the second inhibited by inorganic phosphate. only the second fraction was obtained from similar treatment of an extract of isolated spinach chloroplasts. the two fractions differed distinctly with respect to kinetics for the substrate fructose 6-phosphate. evidence for these two types of phosphofruct ...	1977	16660078
loss of dna and euchromatin in senescing leaf cells of allium.	the leaves of the chive, allium schoenoprasum, have an average life-span of 53 days, then they fade from top to bottom, in the same sequence as cells originated. starting during the adult phase, the amount of dna per nucleus decreases significantly. nuclei of senescent cells exhibit about 15% less dna than nuclei of juvenile cells. electron-microscopic investigations have shown that the diffuse chromatin is lost from the nuclei, followed by shrinkage of the space left. quantitation was achieved ...	1982	7062791
molecular analysis of cytoplasmic male sterility in chives (allium schoenoprasum l.).	the mitochondria of chive plants with normal n or male-sterile s cytoplasms have been examined by restriction fragment analysis and southern hybridizations of mitochondrial dna (mtdna) and in organello protein biosynthesis. restriction fragment patterns of the mtdna differed extensively between n-and s-cytoplasms. the percentage of fragments with different mobility varied between 44-48% depending on the restriction enzyme used. in contrast to mtdna, the restriction fragment patterns of the chlor ...	1993	24190316
