    • ) spotted leaf 5 (spl5) indicates that wild-type SPL5 negatively regulates cell death and resistance responses
    • Bioinformatic analysis showed that SPL5 gene encodes a putative splicing factor 3b subunit 3 (SF3b3) and might be involved in splicing reactions of pre-mature RNAs participating in the regulation of cell death and resistance responses
    • The data presented here clearly indicate that the SPL5 negatively regulates cell death and resistance responses via modulating RNA splicing in plants
    • SPL5, a cell death and defense-related gene, encodes a putative splicing factor 3b subunit 3 (SF3b3) in rice
    • Rice mutant, spl5 (spotted leaf 5), has spontaneous hypersensitive-like lesions on its leaves and shows enhanced resistance to pathogens, indicating that SPL5 plays a role in programmed cell death (PCD) and disease resistance
    • Since the serotonin plays a critical role in inducing disease-resistance, the increased serotonin level may contribute, at least partly, to the disease resistance in spl5
    • The SPL5 gene may act as a negative regulatory factor activating the serotonin metabolic pathway, and these results might provide a new insight into the spl5-induced defense response mechanisms in plants
    • Interestingly, according to our microarray and real-time PCR assays, the expressions of a transcription factor OsWRKY14 and genes responsible for the biosynthesis of serotonin, anthranilate synthase (AS), indole-3-glycerolphosphate synthase (IGPS), tryptophan synthase (TS) and tryptophan decarboxylase (TDC) were significantly up-regulated in the spl5 mutant
    • Transcriptome profiling of the spl5 mutant reveals that SPL5 has a negative role in the biosynthesis of serotonin for rice disease resistance.
