Interests: plant ecology; plant ecophysiology; fire ecology; plant secondary metabolism; plant abiotic stress; global change
Rapid climate changes, occurring naturally or due to human interventions, are well documented worldwide and include warming and drought (and the associated forest fires) or floods depending on the region. The capacity of single trees and shrubs or entire forest ecosystems to survive climate changes is thus critical to the maintenance of their ecological and social services. To face climate changes, forest species modulate their physiological functioning, eventually resulting in changes in their metabolome (production and composition) and morphology. These morpho-chemical modifications (in living plants and litter) are very diverse and include, non-exhaustively, plant growth, litter production, leaf density, tissue, trichome and stomata development and distribution, and production of both primary (e.g., lignin, primary antioxidants) and specific metabolites (e.g., phenolic compounds, terpenes).
Despite the vast amount of literature reporting metabolic and/or morphological modifications under climate change, several fundamental points remain poorly addressed, including the role of such modifications in forest health (CO2 uptake, oxidative pressure), their trade-offs, and metabolite localization as a mechanism to adapt to climate constraints.
This interdisciplinary Special Issue welcomes the submission of articles (original research papers, perspectives, hypotheses, opinions, reviews, modeling approaches, and methods) that tackle changes in metabolomic and/or morphological forest traits in response to climate change, with a focus on living and decomposing plant material, from the cell to the plant and population scales. Such changes can be discussed in the frame of plant health and adaptation to climate change, litter dynamics, or forest functioning as a whole. In addition to these fundamental ecophysiological aspects, this Special Issue welcomes contributions highlighting morpho-metabolomic changes in the context of applied environmental issues exacerbated by climate changes (air pollution, fire hazards), since the plant volatile metabolome is known to modify production of a certain number of air pollutants, and both traits are closely related to plant flammability.

Abstract: Global change scenarios in Mediterranean basin predict a precipitation reduction within the coming hundred years. Therefore, increase drought will affect forests both in terms of adaptive ecology and exosystemic services. However, how vegetation might adapt to drought is poorly understood. In this report, four years climate change was simulated by excluding 35% of precipitation above a downy oak forest. RNASeq data allowed to assemble a genome guided transcriptome. This led to the identification of differentially expressed features which was supported by the characterization of target metabolites using a metabolomics approach. We provided 2.5 Tb of RNASeq data and the assembly of the first genome guided transcriptome of Quercus pubescens. Up to 5724 differentially expressed transcripts were obtained; 42 involved in plant response to drought. Transcript set enrichment analysis showed that drought induces an increase oxidative pressure that is mitigated by the upregulation of ubiquitin-like protein protease, ferrochelatase, oxaloacetate decarboxylase and oxo-acid-lyase activities. Also, the down regulation of auxin biosynthesis and transport, carbohydrate storage metabolism were observed as well as the concomitant accumulation of metabolites as oxalic acid, malate and isocitrate. Our data suggest that early metabolic changes of Q. pubescens resistance to drought involve a TCA cycle shunt through the glyoxylate pathway, galactose metabolism by reducing carbohydrates storage and increase proteolytic activity.
