Figure 4From: Transcriptome profiling of the spl5 mutant reveals that SPL5 has a negative role in the biosynthesis of serotonin for rice disease resistanceA hypothetical model for the SPL5 signaling pathway in rice. The SPL5 may act as a negative regulatory factor activating the serotonin metabolic pathway, which is mediated by OsWRKY14. The accumulation of serotonin may lead to pathogen resistance in rice.Back to article page
