Abstract

The observed and predicted rise in global atmospheric carbon dioxide concentration ([C02]), together with potential global warming and changes in precipitation, will undoubtedly have a significant economical and ecological impact on world agricultural crop plants, grasslands and forests. However, the response of tropical species to elevated [C02] and warming has received little attention to date. The major contribution of this research proposal to FAPESP-RPGCC is regarding the production of new and relevant scientific knowledge with emphasis in adaptation of tropical grazing species to a conservative climate change scenario. This proposal has been specifically designed to address a number of highly focused scientific questions in an interdisciplinary approach (in a national and international collaborative effort among agronomists, biologists, plant physiologists, molecular biologists, husbandry specialists) in order to provide milestones and scientific deliverables regarding the responses of contrasting tropical plants to global climate change. This research proposal aims to determine the effects of elevated CO2 (600 ppm) and warming (+ 2°C), induced by infrared heaters, on the physiological, gene expression, biochemical, growth, carbon and nitrogen dynamics and yield responses of two tropical grazing species Panicum maximum (C4 grass) and Stylosanthes. guianensis (C3 legume) grown in consortium on a climate-change impact experiment using a miniF ACE (Free air CO2 enrichment) system. The hypothesis of the proposal is that exposure of plants to high [C02] impact positively the performance of both functional groups grown in consortium, but the responses of plants will be modified by effect of warning. The major challenge of this project is that it will provide the first study concerning adaptation of grass and leguminous plants growing in consortium to the climate expected 50 years from now and regarding the ability of grazing plants to act as CO2 sink in Brazilian tropics.
