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.
Abstract
SBP family plays an important role in the regulation of flowering time and the molecular mecha-nism 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 predict-ed.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.More-over,RcSBP3/4B might serve as crucial factors for activating flowering regulation.The above study sum-marized the situation of Chinese rose SBP-box gene family and offers valuable insights for future investi-gations on the molecular mechanisms governing rose flowering regulation.
