Description

Application of E41 gene in regulation and control of plant embryonic development

Technical Field

The invention relates to the technical field of plant genetic engineering, in particular to application of a peroxisome gene E41 in regulation and control of plant embryonic development.

Background

Peroxisomes are small, ubiquitous organelles in eukaryotic cells, consisting of a single membrane coating. Although peroxisome is small in size and simple in structure, it has high diversity in morphology, protein content, metabolism and the like, can respond to various signals, and plays an important role in growth and development of animals and plants.

Plant peroxisomes contain at least 200 proteins, which are involved in a wide range of physiological functions, including phytohormone biosynthesis, lipid catabolism, reactive oxygen metabolism, etc. (Pan and Hu, 2018). Mutant analysis shows that peroxisomes play a key role in plant propagation, seed development, seed germination and seedling morphogenesis, however, the potential mechanism of peroxisomes still needs to be fully elucidated.

Beta-oxidation is one of the major metabolic functions of plant peroxisomes and is critical for seed development. Arabidopsis mutants severely deficient in beta-oxidation, such as the aim1 mfp2 double mutant of two multifunctional proteins and the acx3 acx4 double mutant of acyl-CoA oxidase, exhibit a trait of stunted embryonic development (Rylott et al, 2006; Rylott et al, 2003; Khan et al, 2012). In addition, arabidopsis and barley RNA interference (RNAi) lines of the transporter CTS of fatty acids into peroxisomes produce small seeds (mendiiodo et al, 2014). In the peroxisome biogenesis mutant, the metabolic function of peroxisome cannot be normally exerted, and the seed development is influenced. Arabidopsis peroxidase protein mutants pex19a, pex19b, pex2, pex10, pex12, pex26/apem9/dayu, pex5-10pex7-2 and pex5-1 pex7-2 mutants are all embryonic lethal, with the embryos shrinking when the heart-shaped embryonic stage is arrested and/or matured (McDonnell et al, 2016; Hu et al, 2002; Sparks et al, 2003; Fan et al, 2005; Li et al, 2014; Bartel, 2010). The T-DNA insertion mutants AtPEX16 and sse1 seeds died after drying and shrinking (Lin et al, 1999).

In many other cases, it is unclear how peroxisome gene mutations lead to certain developmental defect molecular mechanisms, particularly those involved in embryonic development. The search and analysis of the functions of the novel peroxisome proteins contribute to the deepening of the understanding of peroxisomes, the improvement of the understanding of eukaryote biology and metabolism, and the improvement of crop quality, yield and stress resistance.

Disclosure of Invention

The invention provides application of the E41 gene in regulation and control of plant embryonic development, can be used for improving the quality of crops, and provides new gene resources and theoretical guidance for deepening the research on the functions of peroxisomes and the research and application of characters such as plant embryonic development and the like.

The specific technical scheme is as follows:

the invention provides an application of an E41 gene in regulation and control of plant embryonic development, wherein a nucleotide sequence of the E41 gene is shown as any one of SEQ ID No. 1-5.

The invention also provides an application of the E41 protein in regulating and controlling plant embryonic development, wherein the E41 protein is obtained by encoding the nucleotide sequence shown by any one of SEQ ID NO. 1-5.

Wherein the nucleotide sequence shown in SEQ ID NO.1 is a genome full-length sequence of the E41 gene, and the sequence length is 3393 bp; the nucleotide sequences shown in SEQ ID No. 2-5 are nucleotide sequences of different spliceosome coding regions of the E41 gene, and the sequence lengths are 2981bp, 2997bp, 2983bp and 2802bp in sequence; the length of the encoded amino acid sequence is 803aa, 766aa, 604aa and 570aa in sequence.

The invention finds a gene capable of influencing the embryonic development of plants through research, is named as E41, and determines that the protein coded by the gene is positioned in peroxisome through subcellular localization analysis. Furthermore, T-DNA insertion in Arabidopsis thalianaPrepared byE41 gene mutant plants, heterozygous mutants can only be obtained, and wild type and heterozygous in progeny plants correspond to 1: 2 separation ratio. Compared with the wild type, the hybrid mutant has the defects that partial seed development is influenced and the phenotype of shriveling and dry shrinkage is generated. The E41 gene is shown to be a coding gene of plant peroxisome new protein, which can affect the development of plant seeds.

The protein can promote the embryonic development of plants, and the reduction or loss of the activity of the protein can influence the embryonic development of seeds, so that viable seeds cannot be obtained.

Further, the plant is a dicot. Still further, the plant is arabidopsis thaliana.

The plant embryo abnormal development caused by E41 gene deletion shows that the tender seed is white transparent, after maturation, it is shriveled and has no vitality, and the progeny can not obtain the plant of homozygous mutant. The research of the invention shows that the E41 gene is introduced into the plant with abnormal embryonic development to obtain the transgenic plant with normal embryonic development.

The E41 gene provided by the invention has potential application value in crop breeding.

In scientific research, a model plant with embryo dysplasia needs to be constructed, and based on the characteristic that E41 gene function loss causes the embryo dysplasia of the plant, the invention provides the application of the gene in constructing an embryo dysplasia plant model. Specifically, the expression of the plant E41 gene is reduced or not expressed by using a genetic engineering technology.

Further, the application comprises the following steps:

(1) the deletion or the expression quantity reduction of the E41 gene is caused by utilizing gene mutation, gene knockout, gene interference or gene silencing technology, so that a plant model with embryonic dysplasia is constructed.

(2) Introducing the E41 gene into a receptor plant, and culturing to obtain a transgenic plant with acquired function; the recipient plant is a plant with abnormal embryonic development caused by deletion of the E41 gene.

Still further, the plant is arabidopsis thaliana. The constructed arabidopsis thaliana with abnormal embryo development is slow in embryo development or incapable of forming embryo, and gradually shrinks and shrinks along with the maturation of the silique.

Compared with the prior art, the invention has the following beneficial effects:

(1) the invention discloses the influence of plant peroxisome neoprotein coded by E41 gene on embryonic development for the first time, and the lethal character of homozygous mutant caused by mutation of E41 gene.

(2) The invention provides new gene resources and theoretical guidance for deepening peroxisome function research and application of characters such as plant embryonic development and the like.

Claims

The application of the E41 gene in regulating and controlling the plant embryonic development is characterized in that the nucleotide sequence of the E41 gene is shown as any one of SEQ ID NO. 1-5.
The application of the E41 protein in regulation and control of plant embryonic development is characterized in that the E41 protein is obtained by encoding a nucleotide sequence shown by any one of SEQ ID NO. 1-5.
3. The use of any one of claims 1 or 2, wherein the plant is a dicot.
4. Use according to claim 3, wherein the plant is Arabidopsis thaliana.
5. The use of any of claims 1 or 2, wherein the route of application comprises:

(1) utilizing gene mutation, gene knockout, gene interference or gene silencing technology to cause deletion or reduction of expression quantity of the E41 gene, thereby constructing a plant model with abnormal embryonic development;

(2) introducing the E41 gene into a receptor plant, and culturing to obtain a transgenic plant with acquired function; the recipient plant is a plant with abnormal embryonic development caused by deletion of the E41 gene.
6. The use of claim 5, wherein the plant is Arabidopsis thaliana.
