Proposed Symposium Title: GASOTRANSMITTERS: SIGNAL MOLECULES IN PLANT METABOLISM AND DEFENSE ADAPTATIONS

Abstract: Theoretical Background: The role of gasotransmitters in plant physiology during normal or biotic/abiotic stress conditions has drawn considerable attention. Within the diversity of gasotransmitters, most of the research has been focused on nitric oxide (NO), hydrogen sulfide (H2S), and to some extent, carbon monoxide (CO). The potential effect of other gaseous molecules, like H2, sulfur dioxide (SO2), methanol (CH4), and ozone (O3), has also been addressed, but their consideration as “gasotransmitters” is debated. NO and H2S emerged as indispensable signal molecules due to their myriad roles in plant growth development, including germination, root formation, stomatal movement, fruit development/ripening, metabolic reprogramming, microbial interactions, stress adaptation, and, finally, plant defense against pathogens. Being gaseous, these molecules can easily diffuse and modulate cellular compartments easily. Gasotransmitters can interact with one another, with phytohormones (abscisic acid, salicylic acid, jasmonic acid, gibberellin, ethylene, brassinosteroids, cytokinins, and auxin), ions, polyamines, and nutrients. As a result, gasotransmitters can effectively alleviate plant stress by modulating multiple defense mechanisms in plants. Scope: The symposium will cover all possible aspects of gasotransmitter roles in plants involving physiology, biochemistry, molecular biology,” omic” approaches, ecology, and resilience under global/climate change. The organizers will select outstanding speakers from different countries worldwide to represent a spectrum of the scientific community in terms of gender, career stage, and expertise. Goals and objectives: (i) Review state-of-the-art and identify aspects for future research. (ii) Exploit the knowledge to engineer plants for stress resilience, particularly concerning global climate change. (iii) Identify the uses of NO-based molecules/methods for practical applications Importance and Interest: The topic is contemporary and an emerging field. The topics are multidisciplinary and of interest to a diverse audience in plant physiology, ecophysiology, reproductive biology, plant-microbe interactions, and plant biotechnology.

Topics (Up to three): Physiology

Topic 2: Plant, Animal, and Microbe Interactions

Topic 3: Ecophysiology

Justification: Gasotransmitters, such as nitric oxide, hydrogen sulfide, and carbon monoxide, emerged as plant signaling molecules. These are essential for plant growth, development, and stress adaptations. Further, interaction among themselves, plant hormones, and environmental factors make the gasotransmitters crucial for plant survival. The topic encompasses four topics of IBC2024: Physiology, Ecophysiology, Reproductive Biology, and Plant/Animal/Microbe Interactions. As a result, the Symposium would attract a diverse and broad audience at IBC2024. The organizer and co-organizer are from two continents. The speakers chosen are of mixed gender, career stage, and geography. Thus, our Symposium meets all the expectations of IBC2024.
