Abstract
Plant has mechanisms to adapt to sulfur deficiency and grow apparently normal. To elucidate a whole adaptive response to sulfur deficiency, we analyze transcriptome and metabolome of Arabidopsis which are grown normally under sulfur depleted condition. In this presentation, we will show time course data of transcriptome and metabolome of a series of plants, ranging from just after transfer to -S condition to after equilibrium of changes in plant's internal status.
Arabidopsis was grown for three weeks on sulfur-sufficient control medium, transferred to control or -S medium and harvested at 3, 6, 12, 24, 48 and 168 hour-after-transfer. These plants were grown normal after transfer. Transcriptome and non-targeted metabolome of leaves and roots were analyzed using microarray and Fourier transform ioncyclotron MS. Targeted metabolic profiling was also conducted using HPLC and capillary electrophoresis. In this presentation we will show putative adaptive processes to sulfur deficiency.
