Plant Responses to High Ambient Temperature

Thermomorphogenesis refers to the growth of elongated petioles, leaf hyponasty, and early flowering phenotypes in plants grown at a high ambient temperature. Thermomorphogenesis, like other physiological responses in plants, is closely synchronized with other environmental cues and endogenous phytohormones. Recent research has discovered some thermosensing and signaling mechanisms, as well as cross-talk with other signals and natural variations among different ecotypes, all of which lead to a better understanding of plant temperature adaptations.

The last decade, especially in recent years, has seen considerable progress in thermomorphogenesis. The field is at an exciting phase where discoveries are being made rapidly and systematically across diverse areas of thermomorphogenesis. The goal of this Research Topic is to summarize what we have known in plant thermomorphogenesis and provide a platform for presenting exciting new discoveries in this field.

We welcome submissions of different types of manuscripts including original research articles and reviews, including but not limited to:

• New mechanisms underlying temperature sensing and signaling
• Temperature signal integration with other signal cues, such as light or hormones
• Genetic and epigenetic regulation of thermal responses
• Post-transcriptional and post-translational regulation of thermal responses
• The trade-off between growth and defense response under high temperature
• Evolutionary view on plant heat adaption
• Genomic analysis for understanding crop heat adaptions
• Coordination between different organ and/or tissue development under high ambient temperature

Studies in non-model plants are welcomed, but descriptive studies lacking significant biological advances might be rejected without peer review.
