• Temperature Regulation of Plant Hormone Signaling During Stress and Development

  It is important to understand how fluctuating temperatures regulate important plant hormone signaling pathways so that we can develop climate-smart crops that can withstand weather extremes in our dynamically changing world. Increasing average temperatures and more frequent heat waves have negative effects on the food we grow and wild species in natural ecosystems and causes stress in plants. How a plant responds to these temperature extremes is governed by plant hormones. In this review, we highlight our current understanding of how changing temperatures regulate plant hormone pathways during immunity, stress responses, and development. Here we present an overview of known temperature-sensitive or temperature-reinforced molecular hubs in hormone biosynthesis, homeostasis, signaling, and downstream responses. These include recent advances in temperature regulation at the genomic, transcriptional, post-transcriptional, and post-translational levels—directly linking some plant hormone pathways to known thermosensing mechanisms. Where applicable, diverse plant species and various temperature ranges are presented, along with emerging principles and themes.
• Grasslands and Climate Change

  Grasslands are the most extensive terrestrial biome on Earth and are critically important for forage, biodiversity, and ecosystem services. This book brings together an international team of researchers to review scientific knowledge of the effects of climate change on world grasslands, a process we are only just starting to understand.
