- 摘要:
- 将芝麻的SiLTP3序列与大豆的核苷酸序列进行blast比对,发现大豆含有与芝麻该基因同源性高达94%的序列,克隆该基因并命名为GmLTP3。通过GmLTP3的核苷酸序列推测出其氨基酸序列,利用软件进行多重序列比对和系统发育树构建,发现该氨基酸序列与已确定功能的大豆脂质转运蛋白同源性高达99%,与蒺藜苜蓿和巴旦杏的进化距离最近。采用实时荧光定量PCR法对GmLTP3基因进行定量检测,组织表达分析表明,GmLTP3属于组成性表达基因,在大豆的根、茎、叶、花、萌发的种子中均有表达,并且在花蕾、茎和萌发的种子中表达量较高,在根、叶中表达量较低。非生物胁迫诱导表达分析表明,GmLTP3基因能够对IAA、ABA、PEG、NaCl和冷害作出应答。胁迫处理2 h后,GmLTP3表达量均有下调趋势;胁迫处理12 h后,IAA、ABA、PEG、NaCl诱导GmLTP3的表达量均有不同程度的上调,冷害处理则继续下调表达量。
- Abstract:
- In this study,a gene which have 94% identity with the SiLTP3 was cloned and named as GmLTP3. GmLTP3 encodes a lipid-transfer protein(LTP)that have 99% identity with the known Glycine max lipid transfer protein.The transcriptional level of GmLTP3 was quantitatively determined using realtime-PCR,it was expressed in almost all the tissues,such as root,stem,leave,flower and seed.It was highly expressed in alabastrum,7-days old stem and 3-days germinating seed,while it was lowly expressed in root and leave.When treated by abiotic stress,such as IAA,ABA,PEG and NaCl,the expression level was down-regulated after treated 2 hours,but was up-regulated after treated 12 hours,while it was downregulated consistently after treated by cold stress.
