Paramecium continues to be used to study motility, behavior, exocytosis, and the relationship between the germ and the somatic nuclei. Recent progress in molecular genetics is described. Toward cloning genes that correspond to mutant phenotypes, a me

We have generated a transformation marker for Paramecium using a Paramecium expression vector (pPXV) and the open reading frame (ORF) of the bacterial antibiotic resistance gene aminoglycoside 3'-phosphotransferase-II (APH-3'-II or neor) from the tra

An Ile-136----Thr substitution in calmodulin reduces the Ca(2+)-dependent K+ currents of cam2, a behavioral mutant of Paramecium tetraurelia, and renders it overly susceptible to BaCl2. DNA fragments carrying the wild-type CAM gene injected into cam2

The cross section for the process γ p → p pp has been measured from threshold up to 4.8 GeV using a tagged photon beam and a multiparticle spectrometer which detected all final state particles. The production cross section rises rapidly from thres

A tagged photon beam and multiparticle spectrometer have been used to measure the backward photoproduction process γp → Δ ++ π − . The energy dependence of the production cross section between 2.8 and 4.8 GeV is studied and found to exhibit sh

The s and t dependence of φ (1019) photoproduction has been investigated in the incident photon energy range 2.8 to to 4.8 GeV. Differential cross-sections and density matrix elements are presented for a t range extending from t min out to −1.3 (G

We present measurements on the inclusive structure function for π 0 photoproduction for the incident photon energy range of 2.8–4.8 GeV. Comparisons are made with electroproduction data and it is found that the scaling behaviour already observed f

A large aperture magnet spectrometer (LAMP 2) is described which was used in a tagged photon beam to collect 1.5 x 10 7 triggers from photoproduction processes in hydrogen. The techniques employed for the data acquisition and subsequent event reconst
