Temperature and Plant Development provides a detailed analysis of the role of temperature fluctuations and stressors in plant development. Renowned experts in plant biology outline plant adaptation to high and low temperature stress, whole plant psychological adaptations, and temperature–regulated gene networks. A hot and interdisciplinary issue, climate change has a tremendous effect on crop production and global food security, and this book actively tends to predictions and fears surrounding those issues. It is a handy resource not only for plant biologists and students, but also for environmentalists and policy makers examining climate change effects.
