Plant Sciences Reviews 2012 provides scientists and students with analysis on key topics in current research, including plant diseases, genetics, climate impacts, biofuels and postharvest. Experts such as Frances Seymour, Roger Jones, Paul Christou and Errol Hewett provide incisive reviews of their fields. Originally published online in CAB Reviews, this volume makes available in printed form the reviews in plant science published during 2012.Table of Contents: 1: The role of plant viroids in diseases - new developments 2: Antioxidant properties in vitro and in vivo: realistic assessments of efficacy of plant extracts 3: Seed orchard genetics 4: Perennial herbaceous crops with potential for biofuel production in the temperate regions of the USA 5: Using near-infrared spectroscopy to predict postharvest quality 6: Influence of climate change on plant disease infections and epidemics caused by viruses and bacteria 7: Aromatic plant species in agricultural production systems based on marginal soils 8: Bioenergy: a potential for developing countries? 9: Appropriate precision agriculture with site-specific cropping system management for marginal and small farmers 10: Increasing the vitamin E content of food by in-plant production 11: REDD reckoning: a review of research on a rapidly moving target 12: Olives and olive oil: diet and health impacts 13: Biofuels: the food versus fuel debate 14: Switchgrass -practical issues in developing a fuel crop 15: Toxicity of Jatropha curcas L. as a biofuel crop and options for management 16: Using metabolomics to improve the quality of harvested fruit 17: Soybean sudden death syndrome – advances in knowledge and disease management 18: High-value horticulture in developing countries: barriers and opportunities 19: The tomato borer Tuta absoluta: insecticide resistance and control failure 20: Genetic diversity in the Jatropha genus and its potential application
