Proteomic response of hybrid wild rice to cold stress at the seedling stage.

ABSTRACT: Low temperature at the seedling stage is a major damaging factor for rice production in southern China. To better understand the cold response of cultivated and wild rice, cold-sensitive cultivar 93-11 (Oryza sativa L. ssp. Indica) and cold-resistant hybrid wild rice DC907 with a 93-11 genetic background were used for a quantitative proteomic analysis with tandem mass tags (TMT) in parallel. Rice seedlings grown for four weeks at a normal temperature (25°C) were treated at 8-10°C for 24, 72 and 120 h. The number of differentially expressed proteins increased gradually over time in the cold-exposed rice in comparison with the untreated rice. A total of 366 unique proteins involved in ATP synthesis, photosystem, reactive oxygen species, stress response, cell growth and integrity were identif
