This invention provides Angelica dahurica AdSVP This invention relates to genes and their applications, belonging to the field of plant molecular biology technology. The Angelica dahurica provided by this invention... AdSVP The CDS sequence of the gene is shown in SEQ ID NO.16, and the amino acid sequence is shown in SEQ ID NO.17. The gene was obtained by overexpression in Arabidopsis thaliana. AdSVP Gene, results showed overexpression AdSVP Arabidopsis plants not only showed significantly greater rates of bolting and rosette leaf number compared to wild-type plants, but also exhibited significantly greater pod length and plant height. AdSVP Gene overexpression not only significantly inhibits flowering in plants and increases the number of rosette leaves in transgenic plants, but also... AdSVP It can also cause transgenic plants to have longer pods and taller plants.

The application relates to the technical field of plant genetic engineering, and particularly discloses LsMAPK6 Protein and its coding gene and application thereof in regulating high-temperature bolting performance of leaf lettuce LsMAPK6 The application finds that the high-temperature bolting performance of leaf lettuce can be regulated by controlling the expression of the protein. LsMAPK6 The application discloses the protein or the coding gene thereof or biological material containing the coding gene and application thereof in regulating the high-temperature bolting performance of leaf lettuce; the high-temperature bolting performance of the leaf lettuce refers to the bolting performance of the leaf lettuce after being treated at 33±2 DEG C. The application has great significance for exploring the high-temperature bolting mechanism, formulating scientific management measures and creating excellent germplasm resistant to bolting.

The application discloses a Sapindus mume SmAP1 gene and application thereof, and the SmAP1 gene is expressed in plants to regulate the flowering time of the plants, and the SmAP1 gene is a nucleotide sequence shown in a sequence table Seq ID NO.1 or a nucleotide sequence encoding an amino acid sequence shown in a sequence table Seq ID NO.2. The application of the Sapindus mume SmAP1 gene is used for cultivating new Sapindus mume varieties with different flowering times. Through observation of the whole transgenic Arabidopsis thaliana plants of 35S::SmAP1 and analysis of the flowering time difference, overexpression of the SmAP1 gene can make the flowering time of the plants advance to different degrees, and the flowering time, days of bolting and the number of rosette leaves of the transgenic Arabidopsis thaliana plants are significantly different from those of wild type plants, which is beneficial to accelerating the breeding cycle of the Sapindus mume species and accelerating the cultivation of high-yield varieties.

The application belongs to the technical field of vegetable breeding, and discloses a method for breeding a bolting-tolerant hybrid of a male sterile line of green radish. The method constructs a host-microorganism synergistic regulation system to maintain the fertility stability of the male sterile line while strengthening its bolting tolerance and vegetative growth potential. The core of the method is to screen and engineer rhizosphere probiotics with double functions of delaying bolting and promoting growth, form an optimal ternary compound microbial agent, and apply it to the whole process of breeding and hybrid seed production of the male sterile line; combined with multi-generation backcross breeding and BrFLC2-InDel1 molecular marker assisted selection, a high-purity, high-yield and bolting-tolerant hybrid of green radish is bred. The application effectively breaks through the negative correlation restriction of stress resistance and high yield, solves the technical problems of fertility instability, difficulty in balancing bolting tolerance and high yield, and lack of precision of microbial intervention in the prior art.

The application discloses a culture method for improving rooting efficiency of Phoebe sheareri tissue culture seedlings, and the rooting efficiency of the Phoebe sheareri tissue culture seedlings is improved through multiple steps of seed disinfection, germination culture, external hormone treatment, active carbon adsorption of secondary metabolites and culture medium optimization, so that the tissue culture efficiency of the Phoebe sheareri is systematically optimized and improved, the survival rate of the Phoebe sheareri tissue culture is improved, and the rooting rate of the Phoebe sheareri is improved from 6.57% to 100%. In addition, the addition of active substances significantly promotes the bolting growth of the Phoebe sheareri, and the bolting rate is increased by about 20% compared with the culture medium without the addition, thereby providing strong support for the subsequent growth of the Phoebe sheareri, especially in the rapid growth of the Phoebe sheareri plant, and providing technical support for commercial application and forestry resource development.

This invention belongs to the field of genetic engineering technology, specifically involving BjuPP2C52 Application of gene-related bioproducts in delaying bolting in plants. This invention utilizes transgenic technology to introduce endogenous genes from *Strombax cuneata*. BjuPP2C52 Overexpression in *Mucor* sp. was observed through phenotypic analysis. BjuPP2C52 The bolting time of plants induced by the gene is significantly delayed, providing important genetic resources and strategies for breeding bolting-resistant varieties of stem mustard.
