Exogenous γ-aminobutyric acid enhances heat tolerance of kiwifruit plants by protecting photosynthetic system and promoting heat shock proteins expression
Kiwifruit plants are highly susceptible to increased atmospheric temperature, and the extreme high temperature often causes the loss of production and quality of the fruit. The γ-aminobutyric acid (GABA) has been widely proved to play important roles in plants in response to abiotic stresses, showing an important potential for application in agricultural industry to overcome environmental challenges. However, application of GABA in kiwifruit plants to resist external stresses has not been reported yet. This study found that pre-irrigation of kiwifruit plants with 0.5 mM GABA was effective in alleviating the heat damage on them. GABA treatment led to better antioxidant capacity and reduced ROS production in kiwifruit plants under high temperature. Moreover, exogenous GABA protected the photosynthetic system of kiwifruit plants when exposed to high temperature. Particularly, we found that endogenous ABA, Glu, Pro metabolisms were participated in the GABA-mediated heat resistance of kiwifruit plants. Furthermore, GABA treatment induced higher expression of AdHsps in kiwifruit plants, being partly responsible for their better performance under heat stress. In summary, this research first demonstrated that exogenous GABA treatment plays a positive role in kiwifruit plants to response to extreme heat stress.
期刊介绍:
Annals of Agricultural Sciences (AOAS) is the official journal of Faculty of Agriculture, Ain Shams University. AOAS is an open access peer-reviewed journal publishing original research articles and review articles on experimental and modelling research at laboratory, field, farm, landscape, and industrial levels. AOAS aims to maximize the quality of the agricultural sector across the globe with emphasis on the Arabian countries by focusing on publishing the high-quality applicable researches, in addition to the new methods and frontiers leading to maximizing the quality and quantity of both plant and animal yield and final products.
