摘要: The cucumber is one of the most important vegetables worldwide and used as a research model for study phloem transport, sex determination temperature-photoperiod physiology. shoot apex plant tissue in which cell fate organ meristems have been determined. In this study, series whole-genome small RNA, degradome transcriptome analyses were performed on apical tissues treated with high vs. low temperature long short photoperiod. A total 164 known miRNAs derived from 68 families 203 novel 182 identified. Their 4611 targets predicted using psRobot TargetFinder, amongst 349 validated by sequencing. Fourteen six differentially expressed between treatments. eight 16 affected Functional annotations revealed that “Plant hormone signal transduction” pathway was significantly over-represented miRNA targets. miR156/157/SBP-Boxes novel-mir153/ethylene-responsive transcription factor/senescence-related protein/aminotransferase/acyl-CoA thioesterase are two credible miRNA/targets combinations modulating plant’s responsive processes to changes. Moreover, newly evolved, cucumber-specific (novel-mir153) found target 2087 mRNAs prediction has 232 proven analysis, accounting 45.26–58.88% plant. This largest sum genes targeted single best our knowledge. These results contribute better understanding mediating adaptation photoperiod sheds light recent evolution new cucumber.
