A detailed study of the holotype of Sphecomyrma canadensis Wilson, 1985 from Canadian amber has led to the conclusion that the specimen belongs to a new genus, here named Boltonimecia gen.n. Since the taxonomy of stem-group ants is not well understood, in order to find the taxonomic position of this genus, it is necessary to review the classification of stem-group ants in a study of their relat...
Human mitochondrial methionine transfer RNA ðhmtRNA CAUÞ has a unique post-transcriptional modification, 5-formylcytidine, at the wobble position-34 (fC34). The role of this modification in hmtRNA Met CAU for the decoding of AUA, as well as AUG, in both the peptidyland aminoacyl-sites of the ribosome in either chain initiation or chain elongation is still unknown. We report the first synthesis ...
Although many fundamental blue light responses have been identified, blue light dose-response curves are not well characterized. We studied the growth and development of soybean, wheat and lettuce plants under high-pressure sodium (HPS) and metal halide (MH) lamps with yellow filters creating five fractions of blue light. The blue light fractions obtained were < 0.1, 2 and 6% under HPS lamps, a...

Human mitochondrial methionine transfer RNA (hmtRNA(Met)(CAU)) has a unique post-transcriptional modification, 5-formylcytidine, at the wobble position-34 (f(5)C(34)). The role of this modification in (hmtRNA(Met)(CAU)) for the decoding of AUA, as well as AUG, in both the peptidyl- and aminoacyl-sites of the ribosome in either chain initiation or chain elongation is still unknown. We report the...
Xyloglucan, isolated from the soluble extracellular polysaccharides of suspension-cultured sycamore (Acer pseudoplatanus) cells, was digested with an endo-beta-1,4-glucanase purified from the culture fluid of Trichoderma viride. A nonasaccharide-rich Bio-Gel P-2 fraction of this digest inhibited 2,4-dichlorophenoxyacetic-acid-stimulated elongation of etiolated pea stem segments. The inhibitory ...
R um ex m aritim us L. occurs in fre quently flooded sites of lowland flood plains. Upon submergence this species exhibited rapid elongation of shoots, but the response depended upon the developmental stage when flooding was initiated. In the rosette stage, petioles showed a fast and large response; during early stem elonga tion the response of petioles was less, but the extension of the lowe...
