Article
Full-text available
Crop wild relatives are species related to cultivated plants, whose populations have evolved in natural conditions and confer them valuable adaptive genetic diversity, that can be used in introgression breeding programs. Targeting four wild lentil taxa in Europe, we applied the predictive characterization approach through the filtering method to id...

Full-text available
During the last century, the progressive substitution of landraces with modern, high yielding varieties, led to a dramatic reduction of in situ conserved crop diversity in Europe. Nowadays there is limited and scattered information on where landraces are cultivated. To fill this gap and lay the groundwork for a regional landrace in situ conservatio...

Many species cannot either migrate or adapt at the rate of temperature increases due to climate warming. Therefore, they need active conservation strategies to avoid extinction. Facilitated adaptation actions, such assisted gene flow, aim at the increase of the evolutionary resilience of species affected by global change. In elevational gradients,...

In this report, Farmer’s Pride project partners assess the potential of the Natura 2000 network to secure crop wild relative (CWR) diversity. They present results of analyses showing the priority CWR populations that occur within the limits of the network and analyse the coverage and efficiency of the Natura 2000 network as a tool for CWR in situ c...
Article
This report describes the work of Farmer’s Pride project partners to increase knowledge about the occurrence of natural populations of crop wild relatives (CWR), as well as the existence of active in situ conservation actions.
Article
The evolutionary potential of populations inhabiting marginal areas has been extensively debated and directly affects their conservation value. Gene flow is one of the main factors influencing selection, adaptive potential and thus, local adaptation processes in marginal areas. The effects of differential gene flow provenance are still not well und...
Article
Full-text available
Populations of widely distributed species often exhibit geographic variation in functional traits in response to environmental heterogeneity. Such trait variation may be the result of different adaptive mechanisms, including genetically based differentiation, phenotypic plasticity or a combination of both. Disentangling the genetic and environmenta...
Article
Full-text available
Crop wild relatives (CWR) can be used to mitigate the negative effects of climate change on crops, but their genetic diversity conservation has not been properly addressed. We propose a new target unit for conservation (Asso-EcoU) based on the occurrence of phytosociological associations in different environments. This approach involves using ecoge...

Crop Wild Relatives (CWR) are receiving significant attention over the last decades. Numerous conservation plans and guidelines to better manage these resources have been developed lately at both national and international levels. In this sense, Spain is following a similar path to that followed by other countries and has included CWR in the Nation...

Crop wild relatives (CWR) have recently received significant attention due to their value as plant genetic resources and their contribution to world food security. We present a prioritized checklist of CWR in Spain in which the criteria of crossability with crops of economic importance, endemicity and threat status have been taken into account. Fir...
Article

The genetic diversity of Patellifolia patellaris has been investigated to generate information required for the organisation of a systematic genetic resources conservation action combining the best elements of the ex situ and in situ conservation concept. To this end, ten occurrences of the species were sampled on the Iberian Peninsula in Portugal...
Article
Full-text available
Habitat fragmentation, i.e., fragment size and isolation, can differentially alter patterns of neutral and quantitative genetic variation, fitness and phenotypic plasticity of plant populations, but their effects have rarely been tested simultaneously. We assessed the combined effects of size and connectivity on these aspects of genetic and phenoty...
Chapter
In the context of flourishing crop wild relative (CWR) conservation studies and initiatives at the national level, the purpose of this chapter is to review the current status of development and implementation of national CWR conservation strategies worldwide, and to perform a comparative study of the different approaches, challenges and solutions p...
Article
Full-text available
Characterization and evaluation (C&E) of CWR and landraces (LR) essential for enhancing their conservation and use—has nearly always involved an element of prediction. In practice, breeders rarely choose accessions for field characterization and evaluation randomly where possible they select accessions they believe are likely to contain the desired...

Predictive characterization methods use ecogeographical and climatic data derived from the specific location of a collecting or observation site, to predict characteristics of accessions and populations that can inform conservation and use options. The predictive characterization methods presented in these technical guidelines for crop wild relativ...

Project
Living organisms can show different responses to climate change. One of them is to migrate both in altitude and/or in latitude in search of more favorable conditions. However, for some species, effective migration is hard to achieve due to habitat fragmentation and limited dispersal. In such cases, these species must adapt to the new environmental conditions, either by non-genetic adaptation (phenotypic plasticity) or by evolutionary adaptation. Some populations experience difficulties adapting genetically to new conditions because they lack the necessary genetic diversity or cannot adapt fast enough to cope with climate change. A potential conservation strategy little studied until now involves selecting and maintaining genetic diversity of adaptive value to endow evolutionary resilience to target populations. Thus, the concept of “assisted evolution” encompasses any action in which there is an intentional human intervention on any of the four evolutionary forces (mutation, genetic drift, genetic flow and selection) for conservation purposes. In this context, the objective of the project is to assess the use of selection and genetic flow as tools to facilitate adaptation and increase the evolutionary resilience of populations affected by climate change. The research will focus on the advance of flowering onset, a trait of enormous adaptive importance in the context of the effects of climate warming. Working with two species of different life cycle and contrasting breeding systems (Lupinus angustifolius and Silene ciliata), the effectiveness of these tools on species with different life history traits will be evaluated. In parallel, the associated genetic risks will be evaluated through the study of potential genetic and phenotypic responses correlated with flowering onset that may also affect the fitness of individuals. The obtained results will help in assessing the feasibility of this type of actions and establishing, when appropriate, the necessary conditions for their application.
Project
Adaptation is one of the main responses of living beings to new environmental conditions. It has been argued that populations that occur at the range limits have great adaptive value as they are found under environmental conditions that are limiting for the species. Nevertherless, this is a controversial statement because it is foreseable that these populations present low genetic diversity on which natural selection can barely operate. The purpose of this project is to assess the processes of local adaptation in the populations of the southernmost limit of distribution of Silene ciliata Pourret (Caryophyllaceae), a plant of the psicroxerophilous pastures of the Mediterranean high mountains, representative of one of the most vulnerable habitats to global change in Spain. The project will analyze the relevance of population size, a key factor in this process. Taking into account possible conservation actions that may be taken to rescue marginal populations, the effect of center-periphery genetic flux on individual fitness of marginal populations will be compared with that of periphery-periphery genetic flux. Finally, the genes expressed during the establishment of Silene ciliata seedlings that may be involved in local adaptation processes will be identified and loci that are under selection will be detected and identified. The combination of field experiment approaches (common gardens with in situ reciprocal sowings), ecogeographical characterization based on field data and geographic information systems, and molecular and genomic techniques, including next generation sequencing, allow an integral perspective of local adaptation and the assessment of the relevance of this process when developing strategies that minimize the impact of global change on biodiversity.
