AdaptOlive Project

 


AdaptOlive Project - Understanding olive adaptations to changing environments: physiology, metabolomics and gene expression


 

Olive (Olea europaea L.) is a major agricultural crop in the Mediterranean basin, including Portugal. This crop tree has an important economic impact in this region; for instance, 98% of the world olive and 78% of the world oil are produced in this region.
Research combining several stresses is particularly important as, in nature, simultaneous stresses are common place. In addition, the emerging climate change scenarios, such as increases of heat waves frequencies and UV radiation accompanied by changes in precipitation patterns, highlighted the need to understand how plants cope with the simultaneous action of several stresses.

This project proposes to investigate the effects of the most common stresses occurring simultaneously in nature (DS, heat and UVB radiation) and subsequent recovery, on the most representative olive cultivars in Portugal (Galega, Cobrançosa, Cordovil de Serpa and Castelo Branco) and Spain (Arbequina), by using an innovative and transversal approach that combines physiology, metabolomics and gene expression analysis. Plant physiological responses (photosynthesis/carbon metabolism/anatomical change/oxidative stress/antioxidant responses), fruit morphological characteristics, plant and fruit metabolite changes (metabolomic analysis: GCMS/HPLCMS/ LCNMR) and the profile of the expression of genes related to stress adaptation/tolerance are investigated.

AdaptOlive Project - Physiology

 


O. europaea cv Cobrançosa experiment: DS + HS + high UVB radiation


  • Plants of O. europaea, cultivar "Cobrançosa", were exposed to DS, HS and UVB radiation separately and to combined DS+HS+UVB. Photosynthsis (chlorophyll a fluorescence, pigments and sugar content), oxidative stress and antioxidante capacity were evaluated.
  • Information concerning the quantum yield of photosynthetic energy conversion was obtained by PAM fluorometry and the saturation pulse method. A large range of photosynthetic parameters (Fv/Fm, Fv´/Fm´, фPSII, qP and NPQ) were calculated, giving insight into the physiological state of O. europaea plants after stresses exposition.

 

 

 

AdaptOlive Project - Physiology and Metabolomics


O. europaea cv Galega experiment: UVB treatment


 

  • Increased ultraviolet-B (UVB) radiation (280-315 nm) due to ozone depletion exert a dramatic challenge for agriculture. To cope with UVB stress plants have evolved a number of protective mechanisms. Photoprotection occurs at a range of scales from processes at the molecular level to organ level mechanisms.
  • Plants of O. europaea, cultivar "Galega", were exposed to three levels of supplemental biologically effective UVB radiation: 0, 6.5 and 14.4 kJ m-2d-1.
    Photosynthesis (chlorophyll a fluorescence, pigments and sugar content), cell cycle dinamics/DNA content, oxidative stress, antioxidante capacity and metabolomic profile were evaluated.
  • Metabolomics: Due to the high diversity of structural classes of metabolites (ranging from primary to secundary metabolites), in the AdaptOlive project we combine different instrument and techniques: 1. Gas chromatography mass spectrometry (GC-MS) and 2. Liquid chromatography-mass spectrometry (LC-MS).
  • Stress affect the metabolic composition of olive. Metabolomics provides a comprehensive analysis of all metabolites present in olive leaves and fruits.
