Abstract:
Inoculation of tubers with fungi non-pathogenic to potato suppresses glycoalkaloid accumulation and elicits accumulation of norsequi and sesquiterpenoids. Inoculation with compatible races of the pathogen Phytophthora infestans suppresses accumulation of terpenoids. Suppressors and elicitors of terpenoid accumulation were isolated from P. infestans . Specificity in the P. infestans - potato interaction appears controlled by suppressors (17-23 glucose units linked β1 → 3. β1 → 6). Ethylene, temperature and aging also markedly influence terpeuoid accumulation.

What is Metabolism?
Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
Overview of Metabolism
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...
