Project description:Current projections for global climate change predict an increase in the intensity and frequency of heat waves and droughts. The improvement in our understanding of the mechanisms of how trees precisely can predict environmental threats and cope with these stresses benefits our natural selection or genetic improvement to the maintenance of forest sustainability. In this work, we investigate the metabolic changes in heat and drought combined stress in Pinus pinaster plantlets. Maritime pine is a coniferous tree with native populations distributed across the European Atlantic and Mediterranean basins and the north of Africa ranging from cool moist to warm dry climates. This species shows high plasticity and a contrasting adaptive capacity and resilience. This plasticity in the response to stress exposure may be associated with a differential ability to modulate their secondary metabolism. For this reason, the current study aims to investigate the gradual and synergetic metabolomic response using liquid chromatography coupled to mass spectrometry (LC-MS) based on untargeted metabolomic profiling of four stress levels. These metabolic profiles were supported by physiological and biochemical determinations. Our results showed that the metabolic profiles induced by low-stress exposition represent an adaptive conditioning mode with metabolome changes that help seedlings to cope with upcoming stress. The metabolism pathways involved in this response were mainly included in amino acid metabolism and carbohydrate metabolism leading to an enhanced accumulation of phenolics, flavonoids, and terpenoids. However, when the plantlets were exposed to higher-stress exposition, the secondary metabolites that starred the response are more complex and decorated, such as alkaloids, lignans, and glycosyloxyflavones. Those changes could help to maintain homeostasis and control the response magnitude on establishing and facilitating the plantlets’ survival. Overall, our findings provide new insights into the responsive mechanisms of the maritime pine under heat and drought stress in terms of metabolic profiles.

Project description:BACKGROUND:Fusarium circinatum, the causal agent of pitch canker disease, poses a serious threat to several Pinus species affecting plantations and nurseries. Although Pinus pinaster has shown moderate resistance to F. circinatum, the molecular mechanisms of defense in this host are still unknown. Phytohormones produced by the plant and by the pathogen are known to play a crucial role in determining the outcome of plant-pathogen interactions. Therefore, the aim of this study was to determine the role of phytohormones in F. circinatum virulence, that compromise host resistance. RESULTS:A high quality P. pinaster de novo transcriptome assembly was generated, represented by 24,375 sequences from which 17,593 were full length genes, and utilized to determine the expression profiles of both organisms during the infection process at 3, 5 and 10 days post-inoculation using a dual RNA-sequencing approach. The moderate resistance shown by Pinus pinaster at the early time points may be explained by the expression profiles pertaining to early recognition of the pathogen, the induction of pathogenesis-related proteins and the activation of complex phytohormone signaling pathways that involves crosstalk between salicylic acid, jasmonic acid, ethylene and possibly auxins. Moreover, the expression of F. circinatum genes related to hormone biosynthesis suggests manipulation of the host phytohormone balance to its own benefit. CONCLUSIONS:We hypothesize three key steps of host manipulation: perturbing ethylene homeostasis by fungal expression of genes related to ethylene biosynthesis, blocking jasmonic acid signaling by coronatine insensitive 1 (COI1) suppression, and preventing salicylic acid biosynthesis from the chorismate pathway by the synthesis of isochorismatase family hydrolase (ICSH) genes. These results warrant further testing in F. circinatum mutants to confirm the mechanism behind perturbing host phytohormone homeostasis.
