Proteomics analysis revealed the activation and suppression of different host defense components challenged with mango leaf spot pathogen Alternaria alternata

ABSTRACT: In this study, we performed a comprehensive proteomic analysis of mango leaves inoculated with the leaf spot pathogen A. alternata. Down-regulated proteins during pathogen invasion and colonization were primarily associated with photosynthesis, the phenylpropanoid and flavonoid biosynthesis pathways, and phenylalanine metabolism. In contrast, significantly up-regulated proteins were involved in tyrosine metabolism and the MAPK signaling pathway, highlighting their critical role in host resistance to the leaf spot pathogen. These findings provide valuable data on protein expression changes, offering potential targets for developing novel management strategies to enhance control of leaf spot disease.

<h4>Background</h4>Mango is an economically important fruit tree in many regions of the world, but is highly susceptible to mango leaf spot disease, caused by Alternaria species. How to manage this disease has been a challenge and therefore understanding the regulation of host molecular components in response to pathogen infection is necessary. In this study, we conducted a comprehensive proteomic analysis of mango leaves upon inoculation with the leaf spot pathogen A. alternata.<h4>Results</h4> ...[more]

Project description:Epidemics of coffee leaf rust (CLR) lead to great yield losses and huge depreciation of coffee marketing values, if no control measures are applied. Societal expectations of a more sustainable coffee production are increasingly imposing the replacement of pesticide treatments by alternative solutions. A good protection strategy is to take advantage of the plant immune system by eliciting its constitutive defenses. Based on such concept, plant resistance inducers (PRIs) have been developed. The Greenforce CuCa formulation made by UFLA (Brazil) is, in addition to acibenzolar-S-methyl (ASM), showing promising results in the control of CLR (Hemileia vastatrix) in Coffea arabica. In order to improve our understanding of the molecular mechanisms of the PRIs, proteomic (2DE-MALDI/TOF/TOF-MS/MS), physiological (leaf gas-exchange) and biochemical (enzymatic) analyses of coffee leaves treated with Greenforce CuCa and ASM and inoculation with H. vastatrix were performed. Proteomic data showed metabolic adjustments mainly related with photosynthesis, protein metabolism and stress responses but, the proteins modulated by the two PRIs were different. Greenforce CuCa, on its own, increased photosynthesis and stomatal conductance, while ASM caused a decrease in these parameters. Upon H. vastratix infection, the Greenforce CuCa showed a higher protective effect on the leaf physiology than ASM. The enzymatic analyses indicated that Greenforce CuCa reinforces the redox homeostasis of the leaf, while ASM seems to increase the involvement of secondary metabolism. So, the PRIs prepare the plant to resist CLR but, inducing different defense mechanisms upon pathogen infection. The data also evidenced the existence of a link between the primary metabolism and defense responses. Furthermore, Greenforce CuCa emerged as a significant agent for CLR management. The identification of components of the plant primary metabolism, essential for plant growth and development that, simultaneously, participate in the plant defense responses can open new perspectives for plant breeding programs.
