Os09g0456200

The rice Os09g0456200 was reported as OsbZIP72 in 2009 by researchers from China.

Annotated Information

Function

• Abscisic Acid (ABA) is an important phytohormone involved in abiotic stress resistance in plants.
• A group of bZIP transcription factors play important roles in the ABA signaling pathway in Arabidopsis.
• The rice OsbZIP72 was proved to be an ABRE binding factor in rice.
• OsbZIP72 was an important regulator in abiotic stress response and ABA signaling transduction pathway.
• OsbZIP72 plays a positive role in drought resistance through ABA signaling, and is potential useful for engineering drought tolerant rice.

Expression

• Quantitative RT-PCR that the expressions of most of the OsbZIPs were signiWcantly induced by ABA, ACC, and abiotic stresses.
• The expression levels of OsbZIP72were relatively high in all tissues, and the expression levels were induced by PEG, NaCl, Cold, ABA and ACC[1].
• As compared among different tissues of the same genes, the expression levels of OsbZIP72 were relatively low in both root and stem[1].
