Round of FORESTIA web seminars
SEMINAR # 7
“GENOMIC TOOLS FOR GENETIC DIVERSITY MANAGEMENT, TRACEABILITY AND BREEDING PROGRAMS OF EUCALYPTS AND OTHER TREE SPECIES”
Dra. Susana N. Marcucci Poltri
IABIMO (UEDD INTA-CONICET), Buenos Aires, Argentina
November 19 at 15h (CET/Paris time)
The International Associated Laboratory FORESTIA starts in 2021 a new round of short seminars aimed at stimulating the scientific comunication among its members, as well as between them and other international laboratories. These seminars are a new opportunity for the FORESTIA scientists to present and discuss their objectives, research work and results on adaptation of forest ecosystems to global changes.
Seminar #7 by Dra. Susana N. Marcucci Poltri (IABIMO (UEDD INTA-CONICET)
Abstract
Our group works on the development and application of different genomic tools to support INTA´s forest and fruit breeding programs distributed throughout Argentina. For eucalypts, we have developed microsatellite markers located in candidate genes related to wood, plant growth and development traits. Recently, we have optimized a protocol for SNP (Single Nucleotide Polymorphism) discovery using ddRADseq strategy which has also been applied in other tree species (plum, peach). Based on leaves transcriptomic experiments, we have collaborated on the generation of novel genomic resources for native tree species of different genus such as Nothofagus, Prosopis and Cedrela.
These genomic tools as well as others publicly available have allowed us to evaluate the genetic diversity of different eucalypts breeding populations (E. grandis, E. dunnii, E. camaldulensis, E. globulus) and clonal seed orchards of pine species (P. taeda, P. caribaea). For clonally propagated fruit trees (such as plum and pecan) we applied these approaches to characterize and look for traceability of plant materials.
We are currently evaluating genomic selection (GS) and association mapping strategies focused on breeding programs of different eucalypts species, in a continuous collaboration with researchers from national and international institutions.
Examples of developed tools and genomic applications will be discussed.
These round of FORESTIA web seminars will take place Fridays every four weeks, starting on the 4th of June 2021.

MiDi is a interdisciplinary Research Thematic Network, focused on biodiversity and habitats and funded by the Centre-Val de Loire Region. The network aims to promote studies in multiple fields of BioGeoSciences and Human and Social Sciences in relation to global changes.
This conference is organised in partnership with the Le Studium (Institute for Advanced Studies).
