Abstract Details

2011, Master of Science, Miami University, Botany.
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.
