High temperature stress is a significant factor limiting rice growth and yield formation. DEAD-box RNA helicase plays a vital role in the processing of pre-rRNA and plant stresses response. Recently, Chinese scientists have great progress in the molecular mechanism of regulating thermo-tolerant of DEAD-box RNA helicase in rice.

Key words: DEAD-box RNA helicase, homeostasis, ribosomal RNA (rRNA), rice, thermotolerance
