FAR-RED ELONGATED HYPOCOTYL3 (FHY3) and its homolog FAR-RED IMPAIRED RESPONSE1 (FAR1),are involved in the regulation of seed germination induced by far red and abscisic acid,but the transcriptional changes of FHY3/FAR1 in dormancy induction process of flower bud is still to be explored.The homologous genes of Arabidopsis thaliana in peach were firstly identified by NCBI blast toolkit.At the same time the expression pattern of the five highest homology genes was characterized during the dormancy induction course,far-red light conditions and ABA-treated conditions,respectively,in floral buds of seven-year-old ‘Zhongyousihao’ nectarine (Prunus persica var.nectariana cv.‘Zhongyousihao’).Quantitative real-time PCR analysis demonstrated that the expression of Prupe.3G186100,Prupe.3G186200,Prupe.4G115100,and Prupe.3G186000 have a up-regulated tendency during the dormancy induction course,also,their transcripts are up-regulated by ABA,down-regulated by far-red light.Conversely,Prupe.2G327900 transcript is down-regulated during both the dormancy induction course and ABA-treated conditions,but up-regulated by far-red light.According to the aforementioned results,we could speculate that PpFRSs may be involved in dormancy induction of flower bud through different methods.
