In the scenario of global warming and climate change, heat stress is a serious threat to crop production worldwide. Being sessile, plants cannot escape from heat. Plants have developed various adaptive mechanisms survive stress. Several studies focused on diversity tolerance levels in divergent Arabidopsis thaliana (A. thaliana) ecotypes, but comprehensive genome scale understanding response still lacking. Here we report transcript responses 10 A. ecotypes (Col, Ler, C24, Cvi, Kas1, An1, Sha, Kyo2, Eri, Kond) originated different geographical locations. During experiment, were subjected (38°C) monitored using NimbleGen ATH6 microarrays. The exhibited considerable variation abundance levels. total, 3644 transcripts significantly regulated (p < 0.01) including 244 transcription factors 203 transposable elements. By employing systems genetics approach- Network Component Analysis (NCA), constructed an silico regulatory network model for 35 responsive during cellular thaliana. computed activities showed ecotype specific treatment.
