Research Biography

Marina C. M. Martins Soldi is a biologist, with PhD in Molecular Plant Physiology (Max Planck Institute of Molecular Plant Physiology, Potsdam-Golm, Germany). She has experience in carbohydrate biochemistry, interaction between carbon and nitrogen metabolism, and enzymology. Since 2012 she works at the Brazilian Bioethanol Science and Technology Laboratory (CTBE) investigating processes that influence plant productivity, such as assimilation, use and storage of carbon and nitrogen..

Carbon Metabolism and Partitioning in Sugarcane
Sucrose is the main product of photosynthesis, the transported sugar and the storage reserve carbohydrate in sugarcane. Although sucrose accumulation has been studied quite extensively in this crop, a true understanding of the biochemical and genetic factors involved in this process is still missing. Information on where and how sucrose accumulation is controlled in the stems of sugarcane is essential for the development of new strategies for agronomic and/or genetic regulation of carbon partitioning and allocation. Our group uses different technologies (e.g. enzyme activity, metabolite level and gene expression) to investigate sucrose metabolism sugarcane.
