| Description | we performed global transcriptome and metabolic profiling in Nipponbare (NIP), 93-11 and CSSL4-1 (a near-isogenic line in 93-11 background with NIP segment) at a series of time points of chilling stress. We observed a significant time-lag response between these two levels, indicating the regulation from transcriptional level to the metabolic response. Among several candidate metabolites, we explored tocopherol and vitamin K1 pathways in chloroplast may play vital roles in chilling stress response in rice. Further overexpression and knock-out of COLD1, the major gene in CSSL4-1, could effectively change the concentration of α-tocopherol, so as to improve the cold tolerance. Therefore, in this study, our systemic analysis at the transcriptional and metabolic levels partially explains the causes of the different tolerances between japonica and indica rice and will facilitate our understanding of the rice adaptation mechanism to low temperature environments. | ||||||||||
