BACKGROUND The vegetative phenotype of the pea mutant unifoliata (uni) is a simplification of the wild-type compound leaf to a single leaflet. Mutant uni plants are also self-sterile and the flowers resemble known floral meristem and organ identity mutants. In Antirrhinum and Arabidopsis, mutations in the floral meristem identity gene FLORICAULA/LEAFY(More)
In studies of the inheritance of resistance, pea seedlings of seven lines in which stems and leaves were both resistant to Mycosphaerella pinodes were crossed with a line in which they were both susceptible. With seven of the crosses resistance was dominant to susceptibility. When F2 progenies of five crosses were inoculated on either stems or leaves(More)
A cDNA clone, OsGAmyb, which encodes a homologue to the barley Myb-like transcription factor, HvGAMyb, was isolated from a rice endosperm cDNA library. The clone was used to show that expression of the OsGAmyb gene in aleurone cells was stimulated by gibberellic acid and the gene product was shown to transactivate an alpha-amylase gene promoter in transient(More)
Morpholino and phosphorothioate (S-DNA) antisense oligos were compared in both cell-free and in-cell translation systems. In the most stringent test of specificity in the cell-free system, a globin-targeted S-DNA oligo was found to inhibit its target sequence at concentrations of 10 nM and above, but the sequence-specific component of this inhibition(More)
The history of the investigation of the sensorimotor control of movement is outlined from its inception at the beginning of the 19th century. Particular emphasis is placed on the opening up of new possibilities by the development of new techniques, from chronophotography to magnetic brain stimulation, all of which have exploited developments in technology.(More)
