compounds against herbivores and microbes, but also as signal compounds to attract …

▪ Abstract As phloem feeders and major vectors of plant viruses, aphids are important pests
of agricultural and horticultural crops worldwide. The processes of aphid settling and …

Plant secondary metabolites, which include a wide variety of phytochemicals, have always

Secondary metabolites (SM) occur in plants in a high structural diversity. The different
classes of SM and their biosynthetic pathways are summarized in this introduction. A typical …

The secondary metabolites of plants were once considered to be waste products-today, their
true value is understood. New methods of separation and structural elucidation, and …

Plants use complex mixtures of secondary compounds (SM) of different structural classes to
protect themselves against herbivores, bacteria, fungi and viruses. These complex mixtures …
