Expression analysis of Hsp70 genes of rice. a Semi-quantitative RT-PCR of selective Hsp70 genes under stress conditions. Rice seedlings were given stress under different conditions as mentioned: HS1 heat shock at 42 °C for 10 min, HS2 heat shock at 42 °C for 1 h, ABA 100 μM abscisic acid for 3 h, CS cold stress at 6 °C for 6 h, SS salt stress in 150 mM NaCl for 6 h, C control maintained at 26 °C. b Microarray based expression profiles during heat stress and recovery conditions as described (Sarkar et al. 2009). HS_10 heat stress at 42 °C for 10 min, HS_60 heat stress at 42 °C for 1 h, HS_Rec 30 min recovery after heat stress at 42 °C for 1 h. c Heat map showing in silico expression data retrieved from Genevestigator (www.genevestigator.com/)
