Transcriptome Analysis of Rice Response to Low Temperature Stress at Booting Stage in Cold Region
Rice is an important food crop in the world,and the whole growth cycle will be threatened by low temperature.In order to explore the discovery of low temperature stress response genes and the regulation mechanism of low temperature response,transcriptome sequencing was performed on young spikelets of cold tolerant variety Longgeng25(LG25)and cold sensitive variety Longgeng11(LG11)under cold stress at booting stage in cold region.The results showed that a total of 11 269 differentially expressed genes(DEGs)were obtained from LG11,while only 1 148 DEGs were obtained from LG25.The GO enrichment analysis showed that the differential genes in LG11 were mostly significantly enriched in the GO terms related to photosynthesis,while LG25 were mostly enriched in the GO terms related to cold response,heat response and pollen development.Under cold stress,both of them significantly enriched to cold response and pollen development.KEGG enrich-ment analysis showed that most of the DEGs in LG11 were significantly enriched in KEGG pathways such as carbon fixation in photosynthetic organic matter and photosynthesis.LG25 was significantly enriched in KEGG pathways such as starch sucrose metabolism,amino sugar metabolism and ribose metabolism.
