Production and Characterization of Growth Hormone Releasing Factor Analogs Through Recombinant DNA and Chemical Techniques
A growth hormone releasing factor analog [Leu27,Hse44]GRF(1–44)lactone has been made by recombinant DNA techniques. The peptide was expressed from a multiple–copied GRF gene fused to lacZ. The monomeric GRF pepti...

The induction of taxol production in the endophytic fungus—Periconia sp from Torreya grandifolia
A Periconia sp was isolated from Torreya grandifolia (a relative of yew that does not synthesize taxol) near Huangshan National Park in the People’s Republic of China. This fungus, not previously known as a tree ...

Three-dimensional cellular development is essential for ex vivo formation of human bone
Tissue engineering of human bone is a complex process, as the functional development of bone cells requires that regulatory signals be temporally and spatially ordered. The role of three-dimensional cellular i...

Serial extraction of endosperm drillings (SEED)—A method for detecting transgenes and proteins in single viable maize kernels
We have developed a method for detecting a transgene and its protein product in maize endosperm that allows the kernel to be germinated after analysis. This technique could be highly useful for several monocot...

Engineering of complex polyketide biosynthesis — insights from sequencing of the monensin biosynthetic gene cluster
The biosynthesis of complex reduced polyketides is catalysed in actinomycetes by large multifunctional enzymes, the modular Type I polyketide synthases (PKSs). Most of our current knowledge of such systems ste...
