Biotrophs depend on the functional metabolism of their hosts for an adequate supply of nutrients, whereas necrotrophs feed on the breakdown products of host degradation (Heisteruber et al., 1994).
To investigate the molecular interaction of biotrophs during disease establishment at the haustorium level, the following research program is proposed:
It is well documented that over 80% of all land plant species form ancient mutualistic interactions with arbuscular mycorrhizal fungi (AMF), soil inhabitants of the monophyletic phylum Glomeromycota [8], which are considered to be obligate biotrophs and complete their life cycle by obtaining the carbohydrate from the host [9,10].
After an informative preface explaining why the study of plant pathology is important and how to use both this introductory textbook and its accompanying CD-Rom, the first chapter provides and explanation of how plant diseases are diagnosed, the 'plant disease triangle', how to determine the cause of a specific disease, what 'biotrophs' and necrotrophs are, disease cycles and they can be utilized.
