Comparative Proteomics Research Of Erect Leaf Mutant From Oryza Sativa L.

Rice (Oryza sativa L.) is an important stable food crop in the world and its leaf is the main organ that carries out photosynthesis and respiration. Rice with erect leaf facilitates sufficient ventilation, efficient photosynthesis and to reduce the incidence of pests and diseases. Therefore, it is theoretical and practical guidance to research the molecular mechanism on the erect leaf mutant in rice. Using high-throughput proteomics technology, the different proteins between of the T65 and 1317 were analyzed from their seedling leaves, tiller leaves, leaf cushions and leaf vein, respectively. Using CapLC-ESI-Q-TOF MS/MS mass spectrometry, a total of 16 proteins were identified. These proteins were categorized into classes related to energy and proteins metabolism such as phosphoglucomutase and phosphoglucose isomerase; regulatory proteins such as HSP70, protein disulfide isomerase, which are mainly involved in protein synthesis and processing, stress response and other processes. Thees differentially expressed proteins between the T65 and 1317 provides new insights for further understanding the molecular mechanisms of erect leaf in plants.
