Figure 3. Promoter analysis and transcripts level of TaVRN2 in response to various abiotic stresses.

Figure 3

A) Putative regulatory cis-elements in TaVRN2 promoter (MBS: MYB binding site involved in drought-inductibilty, ABRE: cis-acting element involved in abscisic acid responsiveness, HSE: cis-acting element involved in heat stress responsiveness, ACE: cis-acting element involved in light responsiveness, DRE: cis-acting element involved in cold stress and TATA-box). The plant CARE and PLACE programs were used for the promoter analysis. B) Transcripts abundance in winter wheat exposed to various stresses. Seven days old plants were exposed to different stresses: Non-acclimated (NA), cold acclimated (CA), wounding (W), heat shock (HS), salt (NaCl), water stress (RWC), abscisic acid (ABA). Data shown represent mean values obtained from independent amplification reactions (n = 4), experiment was repeated three times with similar results. A statistical difference between each sample and the expression observed in non acclimated plants is indicated by an asterisk on top of each histogram columns. The threshold for statistical significance was: *: p<0.05; **: p<0.01; ***: p<0.001; ns: P>0.05.
