Tomatoes are widely planted in the world as vegetables and fruits, and are popular among consumers in various countries. The fruit type of tomato is an important economic trait. At present, most fresh tomato fruits are round juicy fruits, because the round shape is the most favored character by consumers, and the juicy fruits have better mouthfeel. The rapid and accurate improvement of tomato fruit type has been one of the important targets of Chinese breeding.

Claims

1. The use of the protein in any one of the following B1) -B12):

B1) regulating and controlling the shape of the plant fruits;

B5) regulating and controlling the content of the plant juice;

B11) changing the fruit of the plant from a rectangular less juicy fruit type into a round juicy fruit type;

B12) preparing a product which enables the fruit of the plant to be changed from a rectangular less juicy fruit type into a round more juicy fruit type;

the protein is A1) or A2) as follows:

A2) the N end or/and the C end of the protein shown in the sequence 3 in the sequence table is connected with a protein label to obtain a fusion protein;

the plant is a plant of the genus Lycopersicon.

2. Use of the protein-related biomaterial of claim 1 in any one of B1) -B12) of claim 1, said related biomaterial being any one of the following C1) -C10):

C1) a nucleic acid molecule encoding the protein of claim 1;

C2) an expression cassette comprising the nucleic acid molecule of C1);

C10) protoplasts produced by the tissue culture of C9).

3. Use according to claim 2, characterized in that: c1) The nucleic acid molecule is shown as D1) or D2) or D3) as follows:

D1) DNA molecule shown in sequence 1 in the sequence table;

D3) transcribing the DNA molecule of the RNA shown in sequence 5 in the sequence table.

4. Use of a protein according to claim 1 or related biological material according to claim 2 for the cultivation of transgenic tomato plants of the genus round and/or juicy fruit.

5. A method of modifying the fruit shape and/or juice content of a plant, comprising: comprising modifying the expression and/or content of the protein of claim 1 in a plant of interest such that the fruit shape and/or juice content of the plant of interest is modified; the plant is a plant of the genus Lycopersicon.

6. A method of breeding transgenic plants of round and/or juicy fruits, characterized in that: comprising increasing the expression and/or content of the protein of claim 1 in a plant of interest of rectangular fruit and/or low-juice fruit to obtain a transgenic plant; the transgenic plant is round fruit and/or juicy fruit compared with the target plant; the plant is a plant of the genus Lycopersicon.

7. The method of claim 6, wherein: the method for improving the expression and/or the content of the protein in the rectangular fruit and/or the low-juice fruit in the target plant is to express or over-express the protein in the target plant in the rectangular fruit and/or the low-juice fruit in the target plant.

8. The method of claim 7, wherein: the method for expression or overexpression is to introduce the gene coding for the protein in claim 1 into the target plants of rectangular fruit and/or juicy fruit.

9. The method of claim 8, wherein: the nucleotide sequence of the gene encoding the protein of claim 1 is represented by sequence 2 in the sequence table.
