[CBNPMP-Thématique] Plantes médicinalesRésumé : Lavandula angustifolia Mill. or true lavender is an emblematic plant from dry and calcareous hills of the south of France. Lavender essential oils obtained from inflorescences harvested at bloom stage are mainly composed of monoterpenes and few sesquiterpenes. The characteristic lavender smell is due to linalool and linalyl acetate that represent more than half of the emitted volatile organic compound (VOC) quantity. These monoterpenoids are derived from plastidial pathway precursors. The regulation of this pathway in lavender is mainly managed by the successive expression of two DXS during flower development. In the light of 10 years of published data on lavender, it appears that biochemical pathways of main terpenes are mostly depicted. Several transcriptomic libraries are available and a genome at chromosome scale has been assembled and molecular markers developed. The diversity of lavender terpenes and their biosynthesis are reviewed with additional original data regarding the anatomical glandular structures and expression of genes involved in IPP biosynthesis.

Richard Ranunculus lateriflorus Résumé : mall demographic size and reduced genetic diversity increase the extinction probability of a population. Genetic diversity within populations for neutral markers is an heuristic parameter, as it reflects past and ongoing processes acting on populations, and informs on possible futures. This study presents a synthesis of the knowledge on neutral genetic diversity for threatened plants in metropolitan France and the use of such data in management actions. Pairing threatened species with the closest non-threatened species for which we could find appropriate genetic data, we collected information on genetic diversity for 25 threatened species and non-threatened controls. We found that threatened species in France have on average a lower within-population genetic diversity than non-threatened controls and thus are exposed to risks linked to genetic erosion. Combining an analysis of recovery plans and a survey addressed to practitioners, we concluded that genetic diversity is rarely integrated in management actions. The integration of such information into applied conservation remains a challenge. We provide some guidelines to collect biological traits impacting within-population genetic diversity and some specific recommendations for a better incorporation of population genetics concepts into conservations actions.
