'Yukihomare' seedlings in response to flooding Waldenmaier, Hans Eugene Biochemistry Bioinformatics Biology Botany Molecular Biology Plant Biology Plant Sciences flooding water logging vascular cavity soybean Glycine max microarray transcriptome aerenchyma hypoxia PCD programmed cell death Flooding of crop lands results in the displacement of soil oxygen, which causes physiological stress in the plants. Like some other legumes, flooded Glycine max cv. 'Yukihomare' seedlings develop a longitudinal cavity in the vascular cylinder beginning 1.0 cm behind the root tip and progress for varying distances toward the root base. We have investigated the transcriptome during vascular cavity formation in order to identify the involved genes. This study was focused around a 24 hour time course DNA microarray analysis of total RNA during vascular cavity formation. Results indicate 8529 genes are temporally up- or down-regulated two-fold or more during flooding. We found rapid changes in gene expression for ESTs involved in transcription and signal transduction and metabolism. There was two apparent waves of ethylene signaling in response to flooding, suggesting a multistage response. Hallmarks of programmed cell death were observed, and attributed to the formation of vascular cavities. 2011-08-16 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1313012579 http://rave.ohiolink.edu/etdc/view?acc_num=miami1313012579 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
