In recent years, molecular biology has infiltrated into all branches of botany. This is particularly true of plant physiology. This book attempts to provide an introduction to the metabolic and developmental physiology of higher plants from a molecular biological point of view. Starting from the heterocatalytic function of DNA the first ten chapters deal with metabolism, development is presented in the last nine, starting from the autocatalyti...

Patienten, die sich einem operativen Eingriff unterziehen oder Traumen erleben, sind Belastungen ausgesetzt, die priioperativ mit der Nahrungskarenz beginnen und post­ operativ erst dann enden, wenn die Katabolie iiberwunden ist.
