TREX Inra - TECHNICIAN

Signoret
Equipe DADI

Functions - Theme of research

Member of the team ‘Prunus Integrative genetics and Innovation’ (G2IP)

Person in charge of the experiments on peach trees: characterization of fruit quality and resistance to brown rot, for genetic studies and design of ecophysiological models.

  • Management of the plant material (orchards and tunnels): hybridizations, cutting of twigs, thinning, grafting.

 Study of the metabolism of sugars in peach fruit

Description of the evolution of major sugars during the development of fruit in a mapping progeny.

 Analysis of a low  fructose phenotype: creation of recombinants for fine mapping - preparation of samples to follow the expression of the genes implied in the metabolism of sugars.

  • Seeking for resistance to brown rot (Monilinia laxa) in peach

Methodology: management of the strain of the fungus - development of tests of infection.

 Research for sources of resistances: realization of resistance tests on two populations in controlled conditions and in orchard.

 Exploration of the physical barriers: transpiratory losses of the fruit - enumeration of the stomata of fruits - highlighting of the microcracks on fruits.

 Analysis of the biochemical barriers: preparation of samples for analyses of the compounds of surface and skin and for candidate genes expression.

  • Management of the laboratories " physical measures " and " fine quality " of the Unit GAFL
  • Member of the Committee AQR of Unit GAFL
