Fig. 5From: Genome-wide identification of the Jatropha curcas MYB family and functional analysis of the abiotic stress responsive gene JcMYB2 The promoter activity of JcMYB2. Detection of JcMYB2 promoter activity by GUS staining. a wild type. b the transgenic plant under normal cultural condition. c seedlings under 4 °C cultivate condition for 6 h. d seedlings under salt treatment (treated with 200 mM NaCl for 6 h). e seedlings under ABA treatment (treated with 100 μM ABA for 3 h). f seedlings under MeJA treatment (treated with 100 μM MeJA for 6 h). B, C, D, E and F show GUS staining signal except for A. The GUS staining analysis of transgenic Arabidopsis harboring Pro-JcMYB2:: GUS revealed that the JcMYB2 promoter was active in transgenic seedlings. C, D, E and F display GUS staining signal which proved that its activity of JcMYB2 promoter will be increased under cold, salt, ABA and MeJA treatmentBack to article page
