Annotated Information

Gene Symbol

• Os01g0907400 <=> JMJ705,OsJMJ705

Function

• JMJ705 encodes a histone lysine demethylase that specifically reverses H3K27me2/3.
• Overexpression of JMJ705 reduces the resting level of H3K27me2/3 resulting in preferential activation of H3K27me3-marked biotic stress responsive genes and enhances rice resistance to the bacterial blight disease pathogen Xanthomonas oryzae pathovar oryzae.
• Mutation of JMJ705 reduces plant resistance to the pathogen.
• JMJ705 is involved in methyl jasmonate–induced dynamic removal of H3K27me3 and gene activation.
• The results suggest that JMJ705 is a biotic stress-responsive H3K27me2/3 demethylase that may remove H3K27me3 from marked defense-related genes and increase their basal and induced expression during pathogen infection.

Expression

• RT-PCR analysis indicated that JMJ705 was expressed in all tested tissues/organs, with a relatively higher level in rice leaves, and was found to be induced by NaCl, abscisic acid, ethylene (ACC), and JA (see Supplemental Figure 2 online), suggesting that JMJ705 might be involved in stress responses.
• The expression of JMJ705 is induced by stress signals and during pathogen infection.
