KEY MESSAGE: Ethylene formation via methionine reacting with trichloroisocyanuric acid under FeSO4 condition in a non-enzymatical manner provides one economically and efficiently novel ethylene-forming approach in planta. Rice seed germination can be stimulated by trichloroisocyanuric acid (TCICA). However, the molecular basis of TCICA in stimulating rice seed germination remains unclear. In this study, the molecular mechanism on how TCICA stimulated rice seed germination was examined via comparative transcriptome. Results showed that clustering of transcripts of TCICA-treated seeds, water-treated seeds, and dry seeds was clearly separated. Twenty-two and three hundred differentially expressed genes were identified as TCICA treatment responsive genes and TCICA treatment potentially responsive genes, respectively. Two and one TCICA treatment responsive genes were involved in ethylene signal transduction and iron homeostasis, respectively. Seventeen of the three hundred TCICA treatment potentially responsive genes were significantly annotated to iron ion binding. Meanwhile, level of methionine (ethylene precursor) showed a 73.9% decrease in response to TCICA treatment. Ethylene was then proved to produce via methionine reacting with TCICA under FeSO4 condition in vitro. Revealing ethylene formation by TCICA not only may bring novel insights into crosstalk between ethylene and other phytohormones during rice seed germination, but also may provide one economically and efficiently novel approach to producing ethylene in planta independently of the ethylene biosynthesis in plants and thereby may broaden its applications in investigational and applied purposes.
