雌雄异型异熟胡桃楸性别分化关键miRNA的鉴定和分析
Identification and analysis of key miRNA for sex differentiation in hermaphroditic Juglans mandshurica Maxim.
[背景]雌雄异型异熟是雌雄同株向雌雄异株转变的中间过渡形态。珍稀树种胡桃楸是雌雄同株异型异熟植物,分为雌先型和雄先型两种类型,其在东北地区是良好的经济树种和生态树种。MicroRNA(miRNA)是一类内源性真核非编码RNA,其长度为18-24nt左右。在植物中主要通过靶向互补序列,调控靶基因表达,从而控制许多生物学功能。但由 miRNA介导的胡桃楸性别分化和雌雄异型异熟机制的形成尚不清楚。[结果]本研究利用高通量测序技术对胡桃楸雌雄先型的雌雄花…查看全部>>
[Objective]The dioecious heterozygous maturation is an intermediate transition form from monoecious to dioecious plants.The rare tree species Juglans mandshurica Maxim.is a dioecious heterozygous heteromorphic plant,which is divided into two types:female-first and male-first,and it is a good economic and ecological tree species in Northeast China.microRNA(miRNA)is a class of endogenous eukaryotic non-coding RNAs with a length of about 18-24 nt.In plants,they…查看全部>>
