Abstract: In order to reveal the mechanism of 6-benzyl adenine deferring contabescence of rice,the hybrid rice Weiyou 916 seedlings were cultivated with distilled water and 6-benzyl adenine(8 mg / L),respectively,and the proteins expression profile of functional leaves were investigated by using the approach of proteomics. Proteins were extracted from rice functional leaf and separated by two-dimensional gel electrophoresis,then 22 differential expression proteins that induced by 6-benzyl adenine were obtained,among which 15 proteins were identified by matrix-assisted laser desorption / ionization-time of flight mass spectrometry,and categorized into 4 groups of functions including photosynthesis,respiration,hormone metabolism and stress response. Results showed that under nutrient stress condition,6-benzyl adenine had benifical effect on rice plant: the expression abundance of proteins associated with photosynthesis and respiration increased,and proteins associated with contabescence were down-regulated in expression abundance. Thereby,application of 6-benzyl adenine chould enhanced the photosynthesis and respiration directly, provided the material and energy for plant growth and defered rice contabescence.
