PhenoAccess: Physiological Phenotyping of Brachypodium Accessions


EMSL Project ID
50010

Abstract

Although the effects of elevated CO2 on plant growth, physiology and metabolism has been investigated thoroughly, the underlying integrated organismal, cellular and molecular mechanisms of these changes are less understood. Also, two major plant photosynthesis types i.e. C3 and C4 plants, are often affected by all global change parameters in a manner that is distinct from each other. In this study, accessions of Brachypodium distachyon Bd21 (C3 model grass) and Setaria viridis A10.1 (C4 model grass) will be grown under current and elevated CO2 levels in growth chambers. Detailed growth stage-based phenotypic analysis will be performed to reveal different above and below-ground morphological and physiological responses of C3 and C4 grasses to enhanced CO2 levels condition. Also, the whole plant phenotypic observations will be complemented with the stomatal density, stomatal area, epidermal cell area and omics data to further link the observed phenotypic traits in the organismal level to tissue and molecular levels.
