.
Rice is one of the most important crops in the world.
Recently, Professor Roger's team from the School of Tropical Crops of Hainan University published a research paper entitled "Molecular Plant Metabolism Regulation Network" online
.
The study used the combined analysis of metabolome and transcriptome to construct the metabolic regulation network of the main tissues and organs during the whole growth period of rice, and precisely identified the regulatory genes that regulate the accumulation of key metabolites
.
This research is not only of great significance for rice basic research and breeding practice, but also provides a reference for the metabonomics research of other crops throughout the growth period
The study used indica varieties Zhenshan 97 and Minghui 63 samples from different tissues throughout the life cycle, combined with targeted and non-targeted metabolomics analysis methods, and a total of 825 metabolites were annotated and quantitatively analyzed
.
Combining the metabolome and transcriptome data from the same period, the rice metabolic regulatory network (RMRN) was constructed
Using this data set, the study successfully used two independent strategies to analyze new metabolic pathways, using known transcription factors as bait to screen new regulatory networks for lignin metabolism, and identifying unbiasedly based on tissue specificity.

.
Therefore, this study conducted a comprehensive metabolic profile analysis of the whole growth period of rice through multi-omics methods, and its big data resources will also promote the improvement of rice growth regulation, resistance and nutritional quality
