Stress repressive expression of r g

three C2C2-type zinc fingermotifs that are structurally similar to human ZNF265 zinc fingermotifs. SRZ1was expressedwith high level in leaves and markedly repressed by salt, cold, drought and abcisic acid stresses but not by salicylic acid and blast inoculation in rice seedlings. Ectopic have identified several genes that are repressed by abiotic stress from different plant species [4,5]. However, the signal transduc-Furtherwe foundSRZgeneswerewidely distributed amongplant Available online at www.sciencedirect.com Plant Science 174 (2008 redundant; RACE, rapid amplification of cDNA end; RT, reverse transcription;species and their expressions were shown to be down-regulated by abiotic stress. This study indicates that down-regulation of SRZ1 and its relatives in plants may play crucial roles in abiotic-stress tolerance. SA, salicylic acid; SRZ, stress repressive zinc finger protein
