The invention relates to the technical field of poultry cultivation, in particular to a breeding method for increasing the survival rate of forcibly-weaned lambs. The breeding method comprises the following steps: forcibly weaning the lambs aged 10 days; after weaning, performing adaptation period management, internal organ development promoting management and bone development promoting management and respectively feeding different diets during management. According to the breeding method for increasing the survival rate of the forcibly-weaned lambs, provided by the invention, the lambs aged 10 days can be quickly weaned, and after weaning, the good development of various signs of the lambs can be ensured. When the breeding method provided by the invention is adopted for performing weaning management on the lambs aged 10 days, the overall incidence of various diseases during management is lower than 0.03 percent, the development indexes of internal organs are higher, the bone development is faster, and the weight increasing speed is high.

The invention belongs to the field of plant molecular biology, and particularly relates to a loquat flower organ development related transcription factor gene EjPI and application thereof. The full length of the cDNA sequence of EjPI gene is shown in SEQ ID NO. 1, and the amino acid sequence of the coded protein is shown in SEQ ID NO. 2. The EjPI gene of the invention is expressed only in petals,filaments and anthers, but not in sepals and pistils. The EjPI gene overexpression vector is transformed into wild-type arabidopsis and pi-1 mutant by agrobacterium-mediated inflorescence staining. The results show that overexpression of the EjPI gene in wild-type arabidopsis could make the sepals of arabidopsis valvulae and open; and the overexpression of the EjPI gene in the arabidopsis pi-1 mutant can restore petals and stamens. The transgenic plant material obtained by using the EjPI gene overexpression vector can enable the wild-type angiosperms to achieve sepal petalization and can be used for breeding double petal flowers; and the plant pi mutant restores petals and stamens, and a reproduction process is completed effectively. The gene can be used for plant double flower transformation so as to improve ornamental value and restore stamen organs for cross breeding, and has good application prospect.

The invention discloses a cucumber AG-like gene CsMADS24 overexpression carrier and application thereof to flower organ modification, and belongs to the technical field of biology. The carrier is a plant expression carrier containing double 35S promoters and a cucumber gene CsMADS24. A CsMADS24 transgenic plant obtained by overexpressing the CsMADS24 in Arabidopsis thaliana is in a flowering state at the early development stage of flowers; and at the later development stage of the flowers, only few relatively thin and long flowers can be formed, the petals and the stamens of most of the flowers cannot normally develop, and only sepals and carpel develop. The result shows that CsMADS24 play an important control role on the aspect of flower organ development. A novel flower organ variant material obtained by virtue of the gene CsMADS24 can be applied to breeding of crops and ornamental plants and has certain agricultural and ornamental values.

The invention belongs to the technical field of plant gene engineering, and discloses a pleiotropic gene DDF1 (dwarf and delayed flowering 1) for controlling vegetative growth and development of floral organs of rice and application thereof, particularly mapping, cloning, function verification and application of a pleiotropic gene for controlling vegetative growth and development of floral organsof rice. The nucleotide sequence of the gene DDF1 is disclosed as SEQ ID NO.1 in the sequence table, and the amino acid sequence coded by the gene DDF1 is disclosed as SEQ ID NO.2 in the sequence table. The DDF1 determines the vegetative growth and development of floral organs of rice, especially the development of stamen. Gene engineering technology can be utilized to purposefully regulate the expression of the gene in rice, thereby regulating the plant type and fertility of rice, and creating new species of rice seeds. Therefore, the invention has wide application prospects in genetic improvement of rice.

The invention discloses a plant lodging and flower organ development regulation protein ZmLA1, and a coding gene and an application thereof. The protein ZmLA1 is from Zea mays L., and is composed of an amino acid sequence represented by a sequence 1 in a sequence table. The protein or the gene can be used for regulating at least one of the following four properties of a target plant: the auxin-to-base transport efficiency, the auxin lateral transport efficiency, the stem lodging resistance ability and the flower organ development; and the flower organ growth properties comprise at least one of pistillate flowering, tassel flowering, tassel branch number, ear length, ear handle number of filaments, ear fresh weight, cluster length and fruiting rate. The gene and the protein provided by the invention have wide application prospects in the improvement of the properties directly relating to the plant steam lodging resistance, the ideal strain, the flower organ form and the like.
