Metabolite and transcript profiling of Guinea grass (Panicum maximum Jacq) response to elevated [CO2] and temperature.

ABSTRACT: INTRODUCTION:By mid-century, global atmospheric carbon dioxide concentration ([CO2]) is predicted to reach 600 μmol mol-1 with global temperatures rising by 2 °C. Rising [CO2] and temperature will alter the growth and productivity of major food and forage crops across the globe. Although the impact is expected to be greatest in tropical regions, the impact of climate-change has been poorly studied in those regions. OBJECTIVES:This experiment aimed to understand the effects of elevated [CO2] (600 μmol mol-1) and warming (+ 2 °C), singly and in combination, on Panicum maximum Jacq. (Guinea grass) metabolite and transcript profiles. METHODS:We created a de novo assembly of the Panicum maximum transcriptome. Leaf samples were taken at two time points in the Guinea grass growing season to analy
