A method for restoring aquatic vegetation in eutrophicated shellow lake features that the hygrophyte, emergent aquatic plant and flootingleaf and floating plants are used to create a biologic fence for improving the local environment of outrophicated water, and the pilot nursing spermatophyte, following equatic and target plants are gradually introduced into the said fence to form a stable cycle of different aquatic plants in the year round.

The invention discloses a specific primer pair for identification of spermatophyte species and applications of the specific primer pair. The invention provides a pair of specific primers consisting of a single stranded DNA (Deoxyribose Nucleic Acid) A and a single stranded DNA B. The single stranded DNA A is 15-40bp and has a DNA fragment same as the DNA fragment shown as a sequence I in a sequence table. The single stranded DNA B is 15-40bp and has a DNA fragment same as the DNA fragment shown as a sequence II of the sequence table. In the invention, with the ycflb gene of a plant to be tested as a template, the DNA fragment obtained by PCR (Polymerase Chain Reaction) amplification with the specific primer pair is also protected. The DNA fragment can be used for assisting identification of the spermatophyte species. The specific primer pair can be used for developing general kits, effectively identifying land plant species, and promoting the development of plant DNA bar codes, contributing to social progress.

The invention relates to a botanic vegetative growth maintenance gene system, the establishment of a vegetative growth maintenance plant, and a method for utilizing the infinite growth capacity of seed plants. The vegetative growth maintenance gene system comprises a promoter, a cellular lethal factor gene, and a gene device which is arranged when necessary and is used for limiting or eliminating the toxicity of non-target cells of the vegetative growth maintenance gene system; and the utilization of the infinite growth capacity of the seed plants is that the gene system is integrated into a botanic nuclear genome and accurately and correctly begins to perform expression according to given tissues and organs and the specificities of developmental stages. The vegetative growth maintenance gene system can effectively remove cells of reproductive meristems which appear in vegetative apical meristems, and prevent the vegetative meristems from being differentiated, so that a novel, high-yield and high-quality vegetative mass utilization plant, namely the vegetative growth maintenance plant is created; and the vegetative growth maintenance gene system can be applied to all vegetative mass utilization plants, so that the growth speed, production efficiency and yield of vegetative masses of the vegetative mass utilization plants are greatly improved on the original basis.

The invention provides an application of protein in regulating and controlling the selenium content of plant tissues and/or organs. The protein is any one of the following proteins: a) protein with anamino acid sequence as shown in SEQ ID No.7; b) fusion protein obtained by connecting a label to an N terminal or/and C terminal of the protein as shown in SEQ ID No.7; and c) protein related to selenium metabolism and obtained by substituting and/or deleting and/or adding one or more amino acid residues to the amino acid sequence as shown in SEQ ID No.7. The selenium content of the plant tissuesand/or organs is regulated and controlled to increase the selenium content of the plant tissues and/or organs. The selenium content in the plant tissues and/or organs is regulated and controlled to increase the selenium content in the plant tissues and/or organs. The organs are seeds; and plants are spermatophytes.

The invention discloses a specific expression promoter for a plant embryo and application thereof. The promoter is derived from (1) a DNA (Deoxyribonucleic Acid) sequence shown as a sequence 1 in a sequence table, (2) a DNA sequence having over 70 percent of homology with the DNA sequence defined by the sequence 1 in the sequence table and having the function of a specific expression promoter forthe plant embryo, and (3) a nucleotide sequence which can be hybridized with the DNA sequence defined by the sequence 1 in the sequence table under a highly serious condition. The promoter can be used for promoting specific expression of an exogenous gene in the plant embryo, and is suitable for any seed plant.
