The present application relates to a kind of KASP molecular markers related to common pakchoi leaf purple and its application, by QTL-seq technology and genetic map location, the main effect QTL site related to leaf purple located on the 3rd chromosome of common pakchoi is found, and further developed the molecular marker closely linked to site, by the seed or seedling leaf extraction DNA of color unknown common pakchoi material, combined with the KASP primer of the present application carries out KASP molecular marker genotyping test, the color of common pakchoi can be predicted by the genotyping result of marker, without using artificial identification method, can obviously improve breeding efficiency, save breeding cost.

The invention belongs to the field of CRK gene family research, and discloses an identification and expression regulation analysis method of amorphophallus konjac AkCRKs gene family members, which is based on a hidden Markov model of a CRK gene conserved domain, and uses TBtools software to carry out identification and bioinformatics analysis on the AkCRKs gene family members. And the expression characteristics of AkCRKs gene family members in different tissue parts, jasmonic acid, soft rot bacteria (Pcc) and under low temperature stress are analyzed. 19 AkCRKs gene family members are identified in the whole genome of amorphophallus konjac and are non-uniformly distributed on 7 chromosomes. The promoter of the AkCRKs gene family member comprises a plurality of adversity stress response, hormone response, growth and development regulation and other cis-acting elements. The expression of the AkCRKs gene has tissue specificity and participates in response to Pcc, MeJA and low-temperature stress. The research result of the invention provides a basis for further researching the function and adversity stress response mechanism of the amorphophallus konjac AkCRKs gene.

The application belongs to the technical field of genetic engineering, and particularly relates to application of a PsPILS1b gene in regulating flowering of plants. The PsPILS1b gene is first excavated in peony flowers, a coding sequence of the PsPILS1b gene is shown as SEQ ID NO:1, and experiments prove that the PsPILS1b gene is involved in auxin transport in petals, promotes and maintains blooming of flowers. Meanwhile, the PsPILS1b gene is overexpressed in Arabidopsis, and a transgenic group is obviously delayed in petal abscission position, and the flowering period of the Arabidopsis is prolonged, further verifying that the PsPILS1b gene is involved in the peony petal senescence process, and has good application prospect.

The application discloses a method for clearing and controlling recurrence of Spartina alterniflora, which comprises the following steps: firstly, arranging straw stacking fields and landfill pit positions in a Spartina alterniflora clearing area; secondly, mowing, recycling and airing the aboveground part of the Spartina alterniflora before a flowering period; thirdly, excavating the landfill pits according to the terrain, pushing the surface soil containing seeds and residual roots into the landfill pits, covering and compacting the soil, and further performing rotary tillage on the root dense positions to break the roots; and finally, restoring the beach by using the excavated deep earthwork or external planting soil, and planting native vegetation after the terrain is stable. The application mainly utilizes mechanical equipment, is simple and easy to implement, can form a strong interference habitat for the Spartina alterniflora, effectively solves the problem of recurrence of the Spartina alterniflora, and improves the success rate of plant replacement.

The invention provides Angelonia plants comprising a recessive amf1-1 allele that confers to the plant a desired flower color, wherein said flower color is of a higher intensity when at least two copies of said allele are present in a plant when compared to the flower color of a plant lacking said at least two alleles and methods for producing a plant produced by crossing such plants with themselves or with another plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by crossing Angelonia plants comprising a recessive amf1-1 allele. The invention further relates to parts of such plants.

The invention belongs to the technical field of endangered plant breeding, and particularly relates to a seven-flower high-pressure breeding method. The high-pressure propagation method comprises the following steps: S.1, selecting a paris polyphylla plant, and carrying out bark girdling treatment on the base part of a branch; s.2, after the cut of the bark at the girdling part is dried, smearing the cut with a rooting powder solution which takes naphthylacetic acid and indolebutyric acid as main components; s.3, wrapping the branches with a high-pressure breeding box filled with a seedling culture substrate; s.4, daily cultivating and maintaining the branches until a spherical root system is formed; s.5, removing the high-pressure breeding box, and cutting off the bulb root; and S.6, transplanting the branches with good growth conditions into the seedling raising pot filled with the substrate, and transplanting the branches into a field in the next spring after the root system further grows. According to the method, by limiting branch selection and pretreatment, rooting powder solution concentration, matrix and rooting post-treatment in the high-pressure propagation process of the rhodiola rosea, efficient propagation of the rhodiola rosea is achieved, the highest rooting rate can reach 86% through the optimal method, and the rooting condition is good; the highest survival rate can reach 84%.

This invention relates to the field of microbiology, and more particularly to a highly efficient proliferating strain of *Aspergillus cristatus*. The strain is *Aspergillus cristatus* Ec-520, deposited on December 27, 2023, at the Guangdong Provincial Microbial Culture Collection Center (GDMCC), located at 5th Floor, Building 59, No. 100 Xianlie Middle Road, Guangzhou, with accession number GDMCC No. 64205. This invention screens a highly efficient proliferating strain of *Aspergillus cristatus*, further shortening the flowering time, increasing the number of flowers, and achieving better flowering results.

The invention belongs to the technical field of gene engineering, and particularly relates to application of a PsPILS1b gene in regulating and controlling the flowering phase of plants. The PsPILS1b gene is excavated in peony for the first time, the coding sequence of the PsPILS1b gene is shown as SEQ ID NO: 1, and experiments prove that PsPILS1b participates in auxin transport in petals and promotes and maintains flower blooming; meanwhile, the PsPILS1b gene is overexpressed in arabidopsis thaliana, a transgenic group obviously delays the petal falling position, the flowering phase of arabidopsis thaliana is prolonged, it is further verified that the PsPILS1b gene participates in the peony petal aging process, and the PsPILS1b gene has a good application prospect.
