Interactions between Plant Immunity, Temperature, Light, and Circadian Rhythm

Plants respond and adapt to their environment for survival and reproduction. Plant growth, development and fitness are important factors affecting crop production and food security. Plants have evolved inducible defenses in response to biotic and abiotic stresses regulated by temperature, light and circadian rhythm. Activation of plant immune signals against particular pathogen infection is a securely controlled mechanism wherein defense responses are specifically turned on upon recognition of pathogen. As a result, adverse effects on plant growth and development can be controlled and minimized. It remains elusive how interactions between plants and pathogens operate the immune signaling responses in relation to environmental fluctuations. This paper summarizes recent studies demonstrating the interactions between plant innate immunity, temperature, light and circadian rhythm. In addition, our review identifies further research questions and implications for experimental design and analysis to elucidate the complex relationship necessary to explain the interaction between plant immunity temperature, light and circadian rhythm.
