GC-MS-based metabolite profiling of key differential metabolites between superior and inferior spikelets of rice during the grain filling stage.

ABSTRACT:

Background

The asynchronous filling between superior spikelets (SS) and inferior spikelets (IS) in rice has become a research hotspot. The stagnant development and poor grain filling of IS limit yields and the formation of good quality rice. A large number of studies on this phenomenon have been carried out from the genome, transcriptome and proteome level, indicating that asynchronous filling of SS and IS filling is a complex, but orderly physiological and biochemical process involving changes of a large number of genes, protein expression and modification. However, the analysis of metabolomics differences between SS and IS is rarely reported currently.

Results

This study utilized untargeted metabolomics and identified 162 metabolites in rice spikelets. Among them, 17 diffe
