We present the results of two exploratory parsimony analyses of DNA sequences from 475
and 499 species of seed plants, respectively, representing all major taxonomic groups. The …

Because of its requirement for signaling by multiple cytokines, Janus kinase 3 (JAK3) is an
excellent target for clinical immunosuppression. We report the development of a specific, …

Nucleotide sequences of the chloroplast gene rbcL were obtained from Lonicera, Sambucus,
Adoxa, and Cornus. Phylogenetic analyses of these sequences, along with previously …

We have cloned and characterized the first human isozyme in a new family of cyclic nucleotide
phosphodiesterases, PDE9A. By sequence homology in the catalytic domain, PDE9A is …

The endemic Hawaiian lobeliads are exceptionally species rich and exhibit striking diversity
in habitat, growth form, pollination biology and seed dispersal, but their origins and pattern …

As part of our efforts to understand the regulation of intracellular cAMP and to generate new
targets for pharmacological intervention, we have cloned and characterized the first isozyme …

DNA sequences for the plastid locus that encodes the large subunit of ribulose 1,5-bisphosphate
carboxylase/oxygenase (rbcL) were determined for 18 species of monocotyledons in …

Piper is one of the largest genera of flowering plants. The uniformity of its small flowers and
the vast number of species in the genus has hindered the development of a stable …

An equation for acoustic propagation in an inhomogeneous liquid medium with relaxation
loss is systematically derived from the classical dynamic equations together with the …
