Plant Natural Products: Synthesis, Biological Functions and by Herwig O. Gutzeit

By Herwig O. Gutzeit

Not like latest books which both concentration solely at the pharmacological homes of plant average items or conceal the secondary metabolism of vegetation as one part regularly plant technology e-book, this is often the 1st to hide all features in a single volume.
It has the entire gains of a latest textbook, together with colour figures, questions and solutions and a complimentary web site. additionally, the introductory chapters supply adequate heritage wisdom within the chemistry and biochemistry of plant average items and their biotechnological functions to permit its use as a real stand-alone textual content for scholar classes.

Biologie für Einsteiger: Prinzipien des Lebens verstehen

Leben ist ein äußerst komplexes Phänomen und läuft doch vom winzigen Bakterium bis zum studierenden Menschen stets nach den gleichen Prinzipien ab. Die Einführung in die Biologie erschließt Kapitel für Kapitel diese grundlegenden Mechanismen und Strukturen. Mit ihrem modernen didaktischen Konzept legt die Einführung in die Biologie dabei auf völlig neue Weise den Schwerpunkt auf die Vermittlung eines wirklichen Verständnisses für die Abläufe in Zellen und Organismen.

Example text

The tissue also requires specific storage compartments within the cell, or within an organ. Finally, messenger ribonucleic acid (mRNA) and proteins need to be synthesized. Consequently, regulation of the biosynthesis of enzymes and transporters on a transcriptional or post-transcriptional level is extremely important. 12), at both the right time and location. 19). Transcription factors are DNA-binding proteins that interact with the regulatory promoter regions of the target genes and modulate the rate of transcriptional initiation by RNA polymerase.

17 18 1 Biosynthesis and Chemical Properties of Natural Substances in Plants The shikimate pathway contributes to the synthesis of acridone and indole alkaloids via anthranilic acid or tryptophan. 5). , cocaine) are derived from ornithine, where the polyamine putrescine is a common precursor; however, the pathways diverge before the intermediate tropolone is formed. For a second class of tropane alkaloids, the amino acid phenylalanine is required in addition to ornithine for synthesis of the backbone of the molecule littorine, which is an intermediate on the route to hyoscyamine and scopolamine.

A solid arrow symbolizes one reaction step, and a dashed arrow several reaction steps. 1/SLIM1/MYB/MYC/ WRKY ¼ transcription factors; MAP ¼ mitogenassociated protein; Me-JA ¼ methyl-jasmonate. 1 Selected Classes of Secondary Metabolites Environmental factors such as pathogens, sulfur deficiency and wounding, or nutrients such as glucose, can each induce transcription factors which, in turn, control genes involved in glucosinolate synthesis. This transcriptional control also involves the synthesis of precursors such as tryptophan.
