Summary

This book is meant for those actively involved in fundamental and appl ied aspects of pectin and pectinase research but it is also of value f or those interested in plant cell wall biosynthesis and architecture, phytopathology, food technology and human nutrition. This book not onl y reflects the present status of research in the field but it will tur n out to be a very useful reference work as well.
