Unveiling convergent adaptation in Mediterranean pines to inform a new tool for the management of forest genomic resources

Project description

Checking genetic secrets to combat climate change

Climate change poses a severe threat to forest species, particularly as the genetic makeup of populations struggles to keep pace with rapidly shifting climatic conditions. This disconnect can hinder local adaptation, leading to increased genetic erosion and even extinction. Supported by the Marie Skłodowska-Curie Actions programme, the MedForAct project focuses on three iconic pine species native to the Mediterranean basin: Pinus halepensis, P. pinaster, and P. pinea. By analysing a genomic dataset of around 800 individuals, the project aims to identify key genes that contribute to these species’ adaptation. Ultimately, MedForAct will develop software to assist forest managers in implementing targeted reforestation strategies, enhancing the resilience of forests against climate change.

Objective

The impact of climate change on forest species is predicted to be dramatic due to the insurgence of adaptive lags between the current genetic make-up of populations and the newly established climatic conditions. The consequent disruption of local adaptation is of concern as plants may not be able to readapt or migrate fast enough, which could inflate genetic erosion, eradication and extinction. Ongoing conservation efforts are currently devoted to the characterization of forest genetic resources, with the aim of maximising adaptive potentials and increasing the chance for forests to tackle future conditions. Here, MedForAct will focus on three iconic pine species native to the Mediterranean basin (Pinus halepensis, P. pinaster and P. pinea) to identify a core set of genes and gene networks that may have fostered their convergent adaptation in the face of compelling ecological challenges and despite million years of independent evolution. To tackle this challenge, the project will use a newly produced genomic dataset composed of c. 800 individuals genotyped at c. 100K SNPs representing both neutral and adaptive variation. Detecting signatures of convergent adaptation could highlight the adaptive potential of these species, with implications for the development of genomic-informed management strategies and setting conservation priorities based on predicted climate change scenarios. Following this, MedForAct envisages using the detected top-ranked candidates to develop a new software for forest management, with the aim of providing forest managers with a practical means of implementing targeted reforestation approaches by monitoring the expected adaptive lag of populations using genomics and future climatic predictions.
