Molecular genetics, Interaction

Antibiotic substances and their molecular genetics are summarized for the best studied system of fluorescent Pseudomonas, producing up to. seven different compounds. Similar extensive studies should be done for other important rhizosphere bacteria as potential important antagonists for root pathogens. The best-studied example for the effects of vitamins in the rhizosphere is biotin. The molecular genetics of production and uptake of vitamins in the plant-microbe interaction is also a field of interesting future work.

Despite the advent of molecular genetics in neurobiology, our understanding of the functional relationships of the components of the CNS remains in its infancy, particularly in the areas of cellular interaction and synaptic modulation. Nevertheless, the fine structural relationships of most elements of nervous system tissue have been described well [1-5]. The excellent neuroanatomical atlases of Peters et al. [3] and Palay and Chan-Palay [1]... 

The powerful tool of molecular genetics allows the modification of each single amino add in the peptide chain of a protein, e.g. ddetion of side residues necessary for isoprenylation or palmitoylation1361 or introduction of additional charged amino acids for electrostatic interaction with the plasma membrane.1371 Even some artificial modifications can be introduced by means of recombinant enzymes as shown above.
