Water Relations Ko, Dae Kwan [1], cho, eun kyung [2], Hong, Choo Bong [3]. Functional analysis of heat shock protein 70 in flooding-stressed Nicotiana tabacum. Heat shock protein 70 (HSP70)-based chaperone machinery is expected to play a pivotal role in plants under environmental stresses. Three genomic clones, NtHSP70-1, NtHSP70-2 and NtHSP70-3, coding tobacco HSP70s were isolated and analyzed for their expression patterns. Open reading frames of NtHSP70-1, NtHSP70-2, NtHSP70-3 were 653, 653 and 648 amino acid residues, respectively. They all shared three conserved regions, namely C-terminal substrate binding domain, oligomerization domain, and N-terminal ATPase domain. Among them, transcription of NtHSP70-3 was especially increased under flooding-stress in addition to heat shock condition. In light of recent reported results that define the cooperative functions of HSP70 and sHSPs under heat shock condition, there is a possibility that NtHSP70-3 interacts with sHSPs under flooding-stress condition.
