Elevated carbon dioxide (CO2) on maize susceptibility to grey leaf spot

This data intends to show the analysis of B73 inbred line maize plants grown at ambient (415 ppm CO2) and elevated CO2 levels (700 ppm) in separate Conviron growth chambers. Half of the plants in each chamber were inoculated with C. zeina and the remaining control plants mock-inoculated. Disease development and severity was assessed visually and molecularly via a qPCR assay, while the individual effects of CO2 enrichment on maize and fungal growth were also measured. Gas exchange parameters and other maize leaf properties, such as the stomatal density and sugar concentrations, were quantified and compared between the different treatments.本数据集旨在呈现对B73自交系玉米植株的相关分析，这些植株分别种植于独立的Conviron人工气候箱中，培养条件分别为环境CO₂浓度（415 ppm）与升高CO₂浓度（700 ppm）。每个气候箱内的植株中，半数接种玉米尾孢菌（C. zeina），剩余植株作为对照进行模拟接种。病害发生情况与严重程度通过目视观察与实时定量聚合酶链式反应（qPCR）检测进行评估，同时还测定了CO₂富集对玉米及真菌生长的单独影响。气体交换参数及其他玉米叶片性状（如气孔密度、糖分浓度）在各处理组间均进行了定量分析与比较。
