Root metabolites remodeling regulated by γ-aminobutyric acid (GABA) improves adaptability to high temperature in creeping bentgrass

γ Aminobutyric Acid (GABA): A Key Player in Alleviating Abiotic Stress Resistance in Horticultural Crops: Current Insights and Future Directions

“…Recent research on GABA has shown that GABA enhances the adaptability of roots to heat stress by boosting their antioxidant capacity, vitality, and osmotic adjustment. In addition, GABA regulates metabolites under heat stress, enhancing antioxidant capacity, energy metabolism, cellular structures, and osmotic balance in the roots [47]. These findings imply that the exogenous administration of GABA can improve plant growth and survival in the face of heat stress by ameliorating antioxidant capacity and lowering oxidative damage.…”

Editorial: Belowground adaptation of plants to climate change

“…Additionally, the rearrangement and distribution of root metabolites also play significant roles in the overall growth and survival strategy (Atkinson et al in 2012). Here, Li et al (2023) investigated the adaptability of cool-season creeping bentgrass (Agrostis stolonifera) roots to high temperatures induced by global warming, focusing on the role of γ-aminobutyric acid (GABA). The study suggests that GABA plays a crucial role in enhancing the adaptability of cool-season creeping bentgrass roots to high temperatures induced by global warming.…”

“…The interactions between plants and microbiome are complex and have a number of critical players and trophic interactions, which include critical endophytic bacteria and fungi, notably mycorrhizal fungi and nitrogen fixing bacteria, and the rhizosphere microbiome which include important bacteria, archaea and fungi which provide the plant some critical functions. Add in the complexity of the trophic interactions between plants, mycorrhizae and hyphosphere microbiome (Li et al 2023;Wang et al 2023a) and it is easy to appreciate how complex this invisible belowground interaction is.…”
