| 1 | A basic helix-loop-helix transcription factor, PhFBH4, regulates flower senescence by modulating ethylene biosynthesis pathway in petunia显示文摘The basic helix-loop-helix(bHLH)transcription factors(TFs)play important roles in regulating multiple biological processes in plants.However,there are few reports about the function of bHLHs in flower senescence.In this study,a bHLH TF,PhFBH4,was found to be dramatically upregulated during flower senescence.Transcription of PhFBH4 is induced by plant hormones and abiotic stress treatments.Silencing of PhFBH4 using virus-induced gene silencing or an antisense approach extended flower longevity,while transgenic petunia flowers with an overexpression construct showed a reduction in flower lifespan.Abundance of transcripts of senescence-related genes(SAG12,SAG29)was significantly changed in petunia PhFBH4 transgenic flowers.Furthermore,silencing or overexpression of PhFBH4 reduced or increased,respectively,transcript abundances of important ethylene biosynthesis-related genes,ACS1 and ACO1,thereby influencing ethylene production.An electrophoretic mobility shift assay showed that the PhFBH4 protein physically interacted with the G-box cis-element in the promoter of ACS1,suggesting that ACS1 was a direct target of the PhFBH4 protein.In addition,ectopic expression of this gene altered plant development including plant height,internode length,and size of leaves and flowers,accompanied by alteration of transcript abundance of the gibberellin biosynthesis-related gene GA2OX3.Our results indicate that PhFBH4 plays an important role in regulating plant growth and development through modulating the ethylene biosynthesis pathway. | Jing Yin Xiaoxiao Chang Takao Kasuga Mai Bui Michael S Reid Cai-Zhong Jiang | 2015 | Horticulture Research2015，2，1： | 7 |
