Embodiment 1

[0025] Example 1: Acquisition of gene encoding BmbZIP62 transcription factor in filial bamboo

[0026] 1. RNA extraction

[0027] The extraction material was bamboo shoots of filial piety bamboo. RNA was extracted using the Yuanping Hao RNAPure Ultra-Pure Rapid Extraction Kit, extracted according to the operating instructions, and stored at -80°C for later use.

[0028] 2. cDNA first-strand synthesis and reverse transcription PCR

[0029] The total RNA was reverse-transcribed into cDNA using the Whole Type Gold (Beijing) one-step cDNA synthesis kit, following the operating instructions. Reaction system and reaction conditions are: 2 μg prepared total RNA, Anchored Oligo(dT) 18 Primer 1μL, 10μL 2×TS Reaction Mix, 1μL TransScript RT / RI Enzyme Mix, 1μL gDNARemover, add RNase-free Water to make up to 20μL, mix gently and centrifuge. Reverse transcription at 42°C for 30 minutes in a PCR instrument, 5s at 85°C; cool on ice; store at -20°C after centrifugation.

Embodiment 2

[0033] Example 2: Functional Analysis of BmbZIP62 Transcription Factor of Filial Bamboo

[0034] 1. Sequence comparison analysis

[0035] In order to analyze the genetic relationship between BmbZIP62 of filial bamboo and bZIP transcription factors in model plants Arabidopsis and rice, a phylogenetic tree of BmbZIP62 and bZIP transcription factors in other species was established using MEGA7. result( figure 2 ) indicated that BmbZIP62 had the closest relationship with rice OsbZIP62 and OsbZIP29 transcription factors.

[0036] The amino acid sequence homology of BmbZIP62 and its closest relatives OsbZIP62 and OsbZIP29 was analyzed by DNAMAN8. Analysis results such as image 3 As shown, the sequence similarity between BmbZIP62 and OsbZIP62 is 61.27%, and the sequence similarity between BmbZIP62 and OsbZIP29 is 47.97%.

[0037] 2. Arabidopsis transgene analysis

[0038] 2.1 Vector construction

Abstract

The invention discloses a filial bamboo transcription factor BmbZIP62 gene and an application thereof, belonging to the technical field of plant genetic engineering. The transcription factor BmbZIP62 provided by the present invention belongs to the basic leucine zipper transcription factor family, and its nucleotide sequence is shown in SEQ ID NO.1, and the amino acid sequence of the encoded protein is shown in SEQ ID NO.2. The invention reveals the phylogenetic status of the gene encoding the BmbZIP62 transcription factor of Bamboo filial piety through gene cloning, expression and comparative analysis. Overexpression in the Columbia type Arabidopsis plant can change the leaf shape and shorten the petiole of the rosette leaves of the plant; Overexpression in rice can dwarf plants. In addition, a method of applying the gene is provided, and the gene will play an important role in studying the developmental mechanism of plant dwarfing, leaf shape change and petiole shortening.

Description

technical field [0001] The invention belongs to the technical field of plant genetic engineering, and in particular relates to a transcription factor BmbZIP62 gene of filial bamboo (Bambusa multiplex) and an application thereof. Background technique [0002] The bZIP (basic leucine zipper motif) transcription factor is one of the most widely distributed and conserved transcription factors in eukaryotes. The A subfamily is mainly involved in the regulation and expression of ABA and environmental stress, the C subfamily is mainly involved in seed development and environmental stress, the D subfamily is involved in the regulation of antioxidant and pathogen defense, and the B, F, E, I and other subfamilies There are few reports (Jakoby et al., Trendsin Plant Science, 7(3), 106-111, 2002), members of this family participate in the regulation of various biological processes of plant growth and development. Although the biological functions of many bZIP transcription factors have...
