Phototaxis genes on linkage group V inDictyostelium discoideum

Phototaxis of Dictyostelium discoideum Slugs

Functional studies of phototaxis in Dictyostelium discoideum mutants

Dictyostelium discoideum has proven indispensable to elucidate cytoskeletal dynamics. The cytoskeleton plays a key role in almost all cellular processes, including motility, cytokinesis, cell-to-cell and cell-substrate adhesions and intracellular transport. Several actin binding proteins are also involved in these processes, among them are actin crosslinking proteins (for example, filamin and α...

A linkage group of four genes related to morphological traits in lentil (Lens culinaris Medik.)

Monogenic inheritance and linkage among four morphological traits of lentil were established on the basis of F1 observations and analysis of 204 F2 plants in a cross for development of pubescence on peduncle, 228 F2 plants in a cross for tendril formation, 574 F2 plants in 5 crosses for flower numbers per peduncle and 464 F2 plants in 4 crosses for flower color under field conditions. Developme...

Transitions in Dictyostelium discoideum behaviour: influence of calcium and fluoride on slug phototaxis and thermotaxis.

Phototaxis and thermotaxis by slugs of Dictyostelium discoideum show transitions that result in bimodality in phototaxis and temperature-dependent orientation up or down temperature gradients. New steps in the sensory transduction chain for these kinds of behaviour are elucidated from studies using inorganic salts (Ca2+, EGTA, KF) and several mutants. KF enhances bimodality of phototaxis, impro...

Linkage Data for Group V Markers in Neurospora.

paper presents linkage data from crosses with markers in linkage group Ty", Neurospora cicrssa (Group E of HOULAHAN, BEADLE and CALHOUN 1949). Several new markers are reported, and the map relations of a number of other genes are clarified. Many of these data were obtained in the course of an investigation of interference ( STRICKLAND unpublished). Certain of the new markers are in positions wh...
