Photorespiration and plant immunity: Interactions and implications under a changing climate
Climate change has profound impacts on plant growth, productivity, and immunity. Photosynthesis, a key biological process that sequesters atmospheric CO2, plays a crucial role in mitigating the effects of climate change. However, photorespiration, a process that consumes O2 instead of CO2 and is metabolically linked with photosynthesis, is often viewed as a wasteful process that reduces photosynthetic efficiency by nearly 48 % in C3 plants. This reduction has a significant impact on crop yield, given the direct contribution of photosynthesis to biomass accumulation. Over the years, numerous efforts have been made to rectify this perceived metabolic flaw to enhance photosynthetic efficiency. Interestingly, recent studies have unveiled a role for photorespiration in plant immunity, which can vary from positive to negative depending on the plant-pathosystem. A key challenge lies in enhancing photosynthetic efficiency by modulating photorespiration without compromising plant immunity. This review discusses the role of photorespiration in plant immunity under current and future climatic conditions. We explore how photorespiration and photorespiratory pathways influence plant defense, how alterations in photorespiration affect hormonal pathways and subsequently plant immunity, and how manipulations of photorespiration may impact plant growth and defense under elevated CO2 conditions. We highlight the roles of plant hormones such as salicylates and jasmonates as well as reactive oxygen species, in photorespiration-related plant immunity. We conclude that unraveling the underlying mechanisms of photorespiration-involved plant responses to various pathogens provides comprehensive insights for the management, breeding, and genetic improvement of crops, thereby enhancing their resilience to future climate change.
期刊介绍:
Plant Physiology and Biochemistry publishes original theoretical, experimental and technical contributions in the various fields of plant physiology (biochemistry, physiology, structure, genetics, plant-microbe interactions, etc.) at diverse levels of integration (molecular, subcellular, cellular, organ, whole plant, environmental). Opinions expressed in the journal are the sole responsibility of the authors and publication does not imply the editors'' agreement.
Manuscripts describing molecular-genetic and/or gene expression data that are not integrated with biochemical analysis and/or actual measurements of plant physiological processes are not suitable for PPB. Also "Omics" studies (transcriptomics, proteomics, metabolomics, etc.) reporting descriptive analysis without an element of functional validation assays, will not be considered. Similarly, applied agronomic or phytochemical studies that generate no new, fundamental insights in plant physiological and/or biochemical processes are not suitable for publication in PPB.
Plant Physiology and Biochemistry publishes several types of articles: Reviews, Papers and Short Papers. Articles for Reviews are either invited by the editor or proposed by the authors for the editor''s prior agreement. Reviews should not exceed 40 typewritten pages and Short Papers no more than approximately 8 typewritten pages. The fundamental character of Plant Physiology and Biochemistry remains that of a journal for original results.
