Project Title:Guinea Grass elevated CO2 and warming Project
Project Type:Elevated temperature and CO2 treatment
Project Summary:Experiment to test the response of Panicum maximum Jacq.(Guinea Grass) to elevated temperature (+2C) and CO2 (600ppm) or combination at University of Sao Paulo in Ribeirao Preto, Sao Paulo Brazil. Each plot was 2-m in diameter; [CO2] was controlled using Free Air CO2 Enrichment and canopy warming was provided by infrared ceramic heaters as described by Britto de Assis Prado et al. (2016).Samples for untargeted metabolomics (with GC-MS), de novo transcriptomics, and RNASeq, were taken 30 and 50 days post treatment exposure (May 22, 2014 and July 14, 2014). Lyophilized leaf material was sent to the University of Illinois Urbana-Champaign(Ainsworth lab) for the untargeted metabolomics, transcript assembly and RNASeq.
