Comparative analysis on metabolites and gene expression difference of various allelopathic potential rice under weed stress

Comparative analysis on metabolites and gene expression difference of various allelopathic potential rice under weed stress

In this study, allelopathic rice ‘PI312777’ (PI) and non‐allelopathic rice ‘Lemont’ (LE) were used to study gene expression related to secondary metabolism and relative metabolites in soil under field conditions with and without weeding. The results showed that the inhibition rates of PI and LE soil...

Zusammenfassung:In this study, allelopathic rice ‘PI312777’ (PI) and non‐allelopathic rice ‘Lemont’ (LE) were used to study gene expression related to secondary metabolism and relative metabolites in soil under field conditions with and without weeding. The results showed that the inhibition rates of PI and LE soils to barnyard grass were significantly increased under weed stress. The inhibition rate of phenolic acid extracts in PI rhizosphere soils was significantly higher (p
