Early events of Bacillus anthracis germination identified by time-course quantitative proteomics
(WILEY-VCH Verlag, 2006-10)
Germination of Bacillus anthracis spores involves rehydration of the spore interior and rapid degradation of several of the protective layers, including the spore coat. Here, we examine the temporal changes that occur ...
Tomato yellow leaf curl virus: A whitefly-transmitted geminivirus with a single genomic component
(Elsevier, 1991-11)
The genome of the tomato yellow leaf curl virus (TYLCV), a Bemisia tabaci-transmitted geminivirus, was cloned. All clones obtained were of one genomic molecule, analogous to DNA A of African cassava mosaic virus. Nucleotide ...
On the origin of light-induced changes in the proton magnetic relaxation rate of chloroplast thylakoid membrane suspensions
(Elsevier, 1981-03)
The spin-lattice relaxation rate of solvent protons in suspensions of chloroplast thylakoid membranes undergoes a large transient depression following illumination in white light. This change appears to require the presence ...
Properties of the cyanobacterial coupling factor ATPase from Spirulina platensis : II. Activity of the purified and membrane-bound enzymes
(Elsevier, 1986-02-15)
Cyanobacterial (Spirulina platensis) photosynthetic membranes and isolated F1 ATPase were characterized with respect to ATP activity. The following results indicate that the regulation of expression of ATPase activity in ...
Heparin inhibition of ferredoxin-NADP reductase in chloroplast thylakoid membranes
(Elsevier, 1985-02-01)
Heparin, an anionic polysaccharide, inhibited the ferredoxin-catalyzed reduction of NADP in spinach chloroplast thylakoid membranes. Under the same conditions of assay, heparin did not interfere markedly with photoreduction ...
Continued search for the cellular signals that regulate regeneration of dopaminergic neurons in goldfish retina
(Elsevier, 1993-12-17)
Intraocular injections of low doses (0.7-1.4 mM estimated intraocular concentration) of 6-hydroxydopamine (6OHDA) selectively destroy dopaminergic neurons in the inner nuclear layer (INL) of goldfish retina, and they never ...
Getting to the root of plant development: the genetics of Arabidopsis root formation
(Elsevier, 1994-03)
Root development in Arabidopsis thaliana is amenable to molecular genetic analyses because of its simplicity and accessibility. Genetic screens have identified a rich collection of mutants that can be used to address a ...
Properties of the cyanobacterial coupling factor ATPase from Spirulina platensis : I. Electrophoretic characterization and reconstitution of photophosphorylation
(Elsevier, 1986-02-15)
The coupling factor ATPase (F1) from photosynthetic membranes of the cyanobacterium Spirulina platensis was purified to homogeneity by a combination of ion-exchange chromatography and sucrose density gradient centrifugation. ...
Reversal of dibromothymoquinone inhibition of photosynthetic electron transport by bovine serum albumin
(Elsevier, 1980-09)
Addition of bovine serum albumin to cholorplasts inhibited by prior addition of 1 [mu] dibromothymoquinone results in a time- and light-dependent restoration of electron transport activity. The kinetics of this reversal ...
