iTRAQ-Based Proteomic Reveals Cell Cycle and Translation Regulation Involving in Peanut Buds Cold Stress

Cold stress is one major threats to field crops. The cold tolerant ability is a key limiting factor for the popularization of peanut ( Arachis hypogaea L.) in cold areas. Our previous research showed three key metabolic change time points of peanut buds in response to low temperature. The present study applied iTRAQ proteomic to further quantify differentially expressed proteins in three key metabolic change time points. A total of 2684 non-redundant proteins and 333 differentially expressed proteins across the three cold stress treatment points were identified. The results enrich the cold stress regulation network and provide useful information for further improving the ability of peanut under cold stress.
