摘要: 为筛选调控蓖麻株高、叶型及产量相关的优良基因,培育出节间较短、茎体粗壮而长度适中、高产的蓖麻矮化良种。采用cDNA-AFLP技术分析始花期矮秆蓖麻茎秆的cDNA表达差异片段,共回收128条差异片段,114条可在Balatx数据库中查询,39条序列被Blast2GO中的GO注释。这些基因几乎涵盖了与矮化相关的各类基因,涉及细胞生长、分化、信号转导、转录调控、物质与能量代谢及运输等,可能在蓖麻矮化机制中起重要或决定性作用,为揭示蓖麻矮化的分子机制找到新的突破口。

Abstract: Screening good genes related to plant height, leaf type and yields in order to culture an internode shorter, caulome stockiness, length medium, and high-yielding dwarf varieties of castor.This paper analyzed differen-tial cDNA fragmentation of dwarf castor caster on date of initial blooming with cDNA-AFLP technology.It gained 128 bands of differences in genes, of which 114 bands can be finded in Balatx database.39 sequences can be anno-tated by GO of blast2GO.These genes are almost covers all kinds of genes related to dwarf involved in cell growth and differentiation, signal transduction, transcription regulation of substance and energy metabolism and transport, etc.They may be plays an important and decisive role in castor dwarf mechanism.And this will find new break-through to reveal the molecular mechanism of castor dwarf.

Key words: CastoR, Stem, cDNA-AFLP, DiffeRential gene
