【摘要】 SBP家族对月季(Rosa chinensis)开花时间调控和花发育分子机制的研究具有重要意义。对月季SBP-box基因家族进行全基因组鉴定分析,并对该家族潜在负调控因子miR156进行靶基因预测。结果显示,月季SBP-box基因家族包含17个成员,蛋白长度为156～1 075 aa。上游顺式元件主要以胁迫、激素响应和光响应为主。其中12个成员是miR156的潜在靶基因。月季RcSBP4A/4B/8/9基因可能参与花瓣早期发育, RcSBP2/6C基因可能与花瓣成熟相关。RcSBP3/4B可能是潜在的激活开花调控的关键因子。以上研究概述了月季SBP-box基因家族的情况,为进一步研究月季花期调控的分子机制提供参考。更多还原

【Abstract】 SBP family plays an important role in the regulation of flowering time and the molecular mechanism of flower development of Chinese rose(Rosa chinensis). The whole genome of the rose SBP-box gene family was identified and analyzed, and the potential negative regulatory factor miR156 was predicted. The results showed that the rose SBP-box gene family comprises a total of 17 members, with protein lengths ranging from 156 to 1 075 amino acids. The upstream cis-elements were primarily associated with stress responses, hormone signaling, and light responsiveness. Notably, 12 members of this gene family showed potential as target genes for miR156. Specifically, genes RcSBP4A/4B/8/9 in roses are likely to participate in early petal development, while genes RcSBP2/6C may be involved in petal maturation. Moreover, RcSBP3/4B might serve as crucial factors for activating flowering regulation. The above study summarized the situation of Chinese rose SBP-box gene family and offers valuable insights for future investigations on the molecular mechanisms governing rose flowering regulation.更多还原
