Project description:transcriptome response of Arabidopsis cultivar Columbia and WS whole plants and plant tissue roots, hypocotyls and shoots to the spaceflight environment Arabidopsis thaliana was evaluated for its response to the spaceflight environment in three replicated experiments on the International Space Station. Two approaches were used; GFP reporter genes were used to collect gene expression data in real time within unique GFP imaging hardware, and plants were harvested on orbit to RNAlater for subsequent analyses of gene expression with using Affymetrix and SAGE transcriptome analyses. Three tissue types were examined (leaves, hypocotyls and roots) and compared to analyses conducted with whole plants. Transcriptome analyses with whole plants suggested that the spaceflight environment had little impact on the transcriptome of arabidopsis, however, closer examination of selected tissues revealed that there are a number of tissue-specific responses that arabidopsis employs to respond to this novel environment. This experiment was launched on STS-131 in 2010 and was supported by NASA grant NNX07AH27G - Transgenic Plant Biomonitors of Space Flight Exposure to R.J. Ferl and A-L. Paul.

Project description:To adapt to waterlogging in soil, some gramineous plants, such as maize (Zea mays), form lysigenous aerenchyma in the root cortex. Ethylene, which is accumulated during waterlogging, promotes aerenchyma formation. Aerencyma is formedonly in cortex in maise root. Therevore, aerenchyma is one of the model of programmed cell death. However, the molecular mechanism of aerenchyma formation is not understood. Therefore we isolated only cortex cells in maize primary root using laser microdissection. And microarray analysis was perforemed to identify the arechyma formation related genes. For microarray analysis, we designed 4 different experiments. Basal part and apical part of root were used for 1st experiment because arenchyma was formed in basal part of root, but not in apex. In second experiment, basal part of root with 6 hours waterlogged treatment and without treatment were used. And, as aerenchyma was induced by ethylene, ethylene and 1-MCP (inhibitor of ethylen perception) were used for experiment3 and 4.
