氈毛忍冬蕾期延長(zhǎng)相關(guān)基因AGL15的克隆與表達(dá)
[Abstract]:Lonicera macranthoides Hand.-Mazz. It comes from Lonicera, which is one of the Chinese medicinal materials, and its medicinal material is dried flower bud or first blooming flower. It has the effect of clearing heat and detoxifying, dispersing wind and heat. Used for treating carbuncle, larynx, erysipelas, heat-toxic blood dysentery, wind-heat cold, warm fever. But for a long time, how to solve the problem of short bud period and untimely picking is a thorny problem in production and application of Lonicera japonica. Since 1999, the natural variant plant of Lonicera feldis was used as scion. Through many years of grafting screening experiment, the clone of Lonicera feldis with long bud stage and non-spreading flower crown was preliminarily cultivated and named "Honeysuckle in Hunan bud". Through denovo sequencing and analysis of the transcription group of Lonicera feldis in the early stage, a large number of functional and independent intellectual property rights gene sequences were obtained, which provided a large number of data for the further study of Lonicera feldis. There were 20709 Unigene genes with significant difference in expression between the two varieties. Among them, 4 important genes of MADS-box family were obtained, among which AGL15 homologous genes were cloned and their expression was verified. In this paper, LmAGL15, a floral related gene, was isolated from the stem, leaves and buds of Lonicera tenuifolia by homologous cloning. At the same time, the temporal and spatial expression patterns of the gene in different parts of Lonicera feldis were analyzed by real-time quantitative PCR (realtime fluorescence quantitative PCR). At the same time, the overexpression and interference plant expression vectors of LmAGL15 gene were constructed, and the vectors were transferred into Arabidopsis thaliana. After verification, some positive plants were obtained. The main results are as follows: 1. According to the conserved sequence of known gene and primer, the cDNA length of AGL15 gene was successfully obtained from stem, leaf and flower buds of Lonicera feldis by RACE method for the first time, and named LmAGL15 (GenBank accession number: KR028478). Sequence analysis showed that the gene contained MADS domain and K domain, belonging to the MADS-box gene family. The expression differences of LmAGL15 gene in different parts of Lonicera feldis were analyzed by using real-time quantitative PCR and 18SrRNA gene as internal reference gene. There were different expression patterns of LmAGL15 gene in different tissues. It has a certain tissue specificity. LmAGL15 was mainly expressed in buds, but hardly in leaves and stems. The difference of expression of LmAGL15 gene in flowering process of Lonicera feldis was analyzed. The expression of LmAGL15 was the highest in the early stage of flower differentiation and the lowest in the late stage. The overexpression and interfering plant expression vector of LmAGL15 was successfully constructed, and transformed into Arabidopsis thaliana. The positive plant. 4. LmAGL15 gene was overexpressed in Arabidopsis thaliana. Through the phenotype of transgenic plants, it was found that transgenic Arabidopsis could delay flowering. It is suggested that LmAGL15 gene may play an important role in the regulation of flowering.
