Fixation in Spinacia oleracea
Smnmary. Washed whole chloroplasts of Spinacia oleracea isolated and assayed in a tris (hydroxymethyl aminomethane)-HCl bu'ifered sucrose solution exhibited low dark CO.2 fixing activity, whereas washed whole chloroplasts isolated in the same buffer but assayed in that ibuffer without sucrose exh;ibited much greater dark CO2 'fixing activity. The lowered activity could be attributed to the impe...
متن کاملSex Chromosome Translocations in Spinacia Oleracea.
HROMOSOME 1 of Spinacia oleracea, the longest of the complement, con'tains the "alleles" X , X", and Y , that effect sex determination (ELLIS and JANICK 1960; SUTO and SUGIYAMA 1961; IIZUKA and JANICK 1962). The genotype X X is pistillate, X"X and X"X" are potentially monoecious (although X"Xm is more highly male), and X Y and X"Y are staminate. The standard chromosome 1 is heterobrachial with ...
متن کاملNovel defensin subfamily from spinach (Spinacia oleracea).
Antimicrobial peptides (So-D1-7) were isolated from a crude cell wall preparation from spinach leaves (Spinacia oleracea cv. Matador) and, judged from their amino acid sequences, six of them (So-D2-7) represented a novel structural subfamily of plant defensins (group IV). Group-IV defensins were also functionally distinct from those of groups I-III. They were active at concentrations < 20 micro...
متن کاملCircular Dna Molecules Associated with Chloroplasts of Spinach, Spinacia Oleracea
Results of cytochemical studies (Sagan and Scher, 1961 ; Ris and Plaut, 1962 ; Kislev et al ., 1965) and of studies involving cell fractionation and buoyant density analyses (Sager and Ishida, 1963 ; Ray and Hanawalt, 1964 ; Brawerman and Eisenstadt, 1964 ; Edelman et al ., 1964 ; Wells and Birnstiel, 1969) have shown that chloroplasts of microorganisms and of higher plants contain DNA which is...
متن کاملStructural characterization of Spinacia oleracea trypsin inhibitor III (SOTI-III).
In recent decades, several canonical serine protease inhibitor families have been classified and characterized. In contrast to most trypsin inhibitors, those from garden four o'clock (Mirabilis jalapa) and spinach (Spinacia oleracea) do not share sequence similarity and have been proposed to form the new Mirabilis serine protease inhibitor family. These 30-40-amino-acid inhibitors possess a def...
