小麥春化相關基因的克隆及其功能研究
[Abstract]:The vernalization stage is an important stage in wheat growth and development. In this study, two highly up-regulated ESTs CL13519,Unigene 1312 and two down-regulated ESTs Unigene 4460 Unigene 20 were screened from the high-throughput Illumina sequencing results of the vernalization response transcriptional sets of wheat Liaochun 10 and Jing841 with different vernalization developmental characteristics. Using the spring wheat Liaochun 10 and winter wheat Jing841 as materials, the sequence differences of four candidate ESTs at transcription level and their expression characteristics during vernalization were systematically analyzed, and the gene function was verified by virus-induced gene silencing. CL13519 overexpression vector was constructed and the recombinant vector was introduced into Arabidopsis thaliana by Agrobacterium tumefaciens to analyze the growth and development characteristics of transgenic materials. The main results are as follows: 1. Using the spring variety Liaochun 10 and winter variety Jing841 as materials, the sequence differences of four ESTs were cloned and analyzed. The results showed that CL13519 length 1010 bp,ORF length 681 bp, encode 226 amino acids, and the similarity with Ta HOX1 (Gen Bank:JQ915062.1) is 87.49%. The length of bp,ORF is 282 bp,5'UTR 169 bp,3'UTR 26 bp, which encodes 93 amino acids. The consistency with hard tetraploid wheat dehydrin (Gen Bank:X78432.1) is as high as 851 BP by TAIR on-line analysis. The similarity between Unigene20 length 632 bp, and Chinese Spring 3B chromosome (Gen Bank:HG670306.1) is as high as 83.91l, and the similarity with hypothetical protein F775Serial 32582 (Gen Bank:KD510223.1) is 77.150.The four ESTs were analyzed by real-time fluorescence quantitative PCR. Vernalization characteristics in wheat, The results showed that the expression of CL13519,Unigene1312 was parabolic in Liaochun 10, and reached the maximum at the 5th week, and the expression of Unigene1312 in Jing841 was parabola. At the 5th week, the expression of CL13519 reached its maximum value, and there were two peaks in the expression pattern of CL13519 in Jing841. The maximum value appeared in the fifth week of vernalization, the expression of Unigene4460 in Liaochun 10 was down-regulated, the expression of Unigene4460 in Jing841 increased sharply in the first week and then decreased sharply, and the expression of Unigene20 was wave-like in Liaochun 10 and Jing841. At the fifth week, the lowest expression was found. 3. Using Liaochun 10 as the experimental material, the functional verification system of wheat VIGS gene was successfully constructed by virus induced gene silencing technique (VIGS), and the four selected ESTs were verified and analyzed. The results showed that BSMV infection had a certain effect on the process of spike differentiation of wheat plants. In this experiment, there was almost no difference between the blank control group, the negative control group and the positive control group. The spike differentiation of BSMV:CL13519,BSMV:Unigene1312,BSMV:Unigene20 was later than that of the control, but the BSMV:Unigene4460 infection accelerated the spike differentiation. 4. The CL13519 overexpression vector was successfully constructed with pCAMBIA3301 as expression vector. Through Agrobacterium tumefaciens mediated transformation of Arabidopsis thaliana, herbicide resistance screening and PCR identification of marker genes, positive transgenic T1 plants were obtained. Reproductive growth was earlier than wild-type plants.
