Chlamydomonas reinhardtii flagellar motility mutant pf-14 fails to assemble radial spokes because of a deficiency for assembly-competent radial spoke protein 3 (Huang, B., G. Piperno, Z. Ramanis, and D. J. L. Luck. 1981. J. Cell Biol. 88:80-88). Here, we raise an antiserum to protein 3 and use it to isolate the corresponding structural gene from an(More)
Flagellar radial spokes contribute to the regulation of dynein arm activity and thus the pattern of flagellar bending. We have sequenced the genes for radial spoke protein 4 (RSP4) and RSP6, two of the five proteins that make up the radial spoke head in Chlamydomonas reinhardtii. The two genes, which are tightly linked genetically (B. Huang, G. Piperno, Z.(More)
The pathways that regulate the S-phase events associated with the control of DNA replication are poorly understood. The bone marrow megakaryocytes are unique in that they leave the diploid (2C) state to differentiate, synthesizing 4 to 64 times the normal DNA content within a single nucleus, a process known as endomitosis. Human erythroleukemia (HEL) cells(More)
Sustained post ‘Little Ice Age’ retreat of the northern lobe of the Feegletscher, Valais, Switzerland, has exposed lateral moraines that show pronounced over-steepening on the upper proximal slopes, with upper slope segments displaying angles of up to c. 70o. Paraglacial processes have eroded gullies into the upper slope segments, and associated debris flow(More)
The biflagellate alga Chlamydomonas has been used extensively in the genetic and biochemical analysis of flagellar assembly and motility. We have restored motility to a paralyzed-flagella mutant of Chlamydomonas by transforming with the corresponding wild-type gene. A nitrate reductase-deficient paralyzed-flagella strain, nit1-305 pf-14, carrying mutations(More)
