In recent years plant scientists have been looking at mechanisms by which atmospheric CO2 is taken up and assimilated within the plants. Dr. Moroney has made an important contribution to this area by his finding that CO2 is actively transported across the plasma membrane of the green algae, Chlamydomonas, when it is adapted to low CO2. Moreover, he has identified polypeptides which are induced under these conditions. He now plans to use mutant strains to pursue these studies to determine the localization and function of these systems, and hopefully identify the genes which are activated under these conditions. Dr. Moroney has made important contributions to plant biosciences including bioenergetics in chloroplast thylakoids, and ATP biosynthesis in chloroplasts. His biochemical and molecular investigations of the C accumulating mechanisms will be important in understanding how organisms can adapt under different environmental conditions.

近年来，植物科学家一直在研究大气中二氧化碳被植物吸收和同化的机制。莫罗尼博士对这一领域做出了重要贡献，他发现，当绿藻衣藻适应低二氧化碳时，它会主动地通过质膜运输二氧化碳。此外，他还鉴定了在这些条件下诱导产生的多肽。他现在计划使用突变菌株进行这些研究，以确定这些系统的定位和功能，并有望识别在这些条件下被激活的基因。Moroney博士在植物生物科学方面做出了重要贡献，包括叶绿体类囊体中的生物能量学和叶绿体中的ATP生物合成。他对碳积累机制的生化和分子研究将对理解生物如何适应不同的环境条件具有重要意义。
