This invention relates to the Bg.MEW_38304 gene regulating plant growth and flowering, its encoded protein, and its applications, belonging to the fields of plant molecular biotechnology and genetic engineering. This gene is derived from *Prunus glabra*, with a full-length CDS sequence of 378 bp. The encoded protein contains a conserved SBP domain, and its nucleotide sequence is shown in SEQ ID NO.1. It was cloned from the bracts of the 'Snow White' variety at the BR3 stage. Bioinformatics analysis, subcellular localization, virus-induced gene silencing, and heterologous overexpression experiments verified that the protein encoded by this gene is located in the cell nucleus and cell membrane. Silencing this gene leads to bract and stem / leaf abortion in *Prunus glabra*, while overexpression promotes growth and earlier flowering in *Arabidopsis thaliana*. This application identifies a key gene for *Prunus glabra* bract development, which can be used to promote plant growth and flowering, and has important application value in the molecular breeding of ornamental plants.

This invention discloses a plant stress-resistance composition and its application, wherein the composition uses calcium chloride and / or betaine as active ingredients.

The invention relates to the technical field of fruit tree cross breeding, and discloses a method for obtaining seeds through artificial pollination of figs. The method comprises the following steps: treating Caprifig type figs by using a plant growth regulator to obtain pollen, and transferring the pollen into fig stigmas by using an artificial pollination dry powder method to obtain seeds. The method comprises the following steps: applying a cytokinin plant growth regulator at the stage that the fruit diameter of the Caprifig type figs is less than 3cm for treatment; harvesting mature Caprifig type fruits, separating anther, drying in the shade, and sieving to obtain pollen; fully mixing pollen and starch to form a pollen working agent in a dry powder state; at the stage that the diameter of the pollinated fig fruit is 1-3 cm, a pollen working agent is sprayed into a fruit cavity through a bract opening, so that the pollen working agent is attached to the stigma of a female flower; after the fruits are ripe, harvesting and water-selecting to obtain seeds. By means of the method, pollen with vitality can be obtained, artificial pollination and fruiting of the figs can be achieved, and the method is suitable for fig cross breeding and fruit improvement.
