The invention discloses a method for creating a rice sterile line with a white glumous flower character and application of the method, and belongs to the technical field of plant breeding, and the method comprises the following steps: introducing site-directed mutagenesis of a LOCOs03g40020 gene into a rice thermo-sensitive sterile line or a rice common genic male sterile plant by utilizing a gene editing technology, and carrying out site-directed mutagenesis on the LOCOs03g40020 gene to obtain the rice sterile line with the white glumous flower character. The new rice sterile line with the sterility and the white glumous flower marker is obtained, and in hybrid seed production, abnormal plants are visually recognized and removed through the phenotype of the white glumous flower. The absolute purity of the sterile line is realized and the safety of hybrid seed production is ensured through identification and sorting of double characteristics of seed fluorescence and glume flower color.

The present application relates to the technical field of plant genetic engineering, and specifically discloses a rice lateral small flower regulation gene LF2, a mutant gene thereof and application. The nucleotide sequence of the rice lateral small flower regulation gene LF2 is shown as SEQ ID No. 1, and the amino acid sequence of the encoded protein is shown as SEQ ID No. 2. The gene has an interaction relationship with OsNF-YA3, HAP3J, HAP5A, HAP5B, HAP5D, HAP5E, and regulates the development of rice glume by regulating the expression of G1. The mutant gene of the rice lateral small flower regulation gene LF2 is a single base substitution from T to A at the first base of the fourth intron of the LOC_Os07g44210 gene, which causes mRNA splicing disorder to form various new transcripts, and the transcript sequences are shown as SEQ ID Nos. 3-6. The rice lateral small flower regulation gene LF2 and the mutant gene thereof disclosed in the present application provide more evidence and basis for the "three-flower spikelet" hypothesis and "three-flower spikelet" breeding, and provide a new gene for breeding to increase the number of spike grains, which has very important significance for further improving the yield of rice.

The invention relates to the technical field of rice breeding, in particular to a breeding method of an ornamental rice variety for bonsai. The invention discloses a breeding method of ornamental rice varieties for bonsai. The breeding method comprises the following steps: S1, breeding a dwarf male parent variety PZ-R with green leaves and white stripes and long white miscanthus; s2, breeding female parent varieties PZ-S of clustered spikelet, purplish red spikelet and long red miscanthus; s3, matching and hybridizing to obtain F1-generation seeds F18, planting the F1-generation seeds F18, mixing and harvesting seeds F28 on F18 plants, and taking the seeds F28 as the potted ornamental rice seeds. According to the method, male parents and female parents with various characters are bred separately through a convergent cross breeding method, dwarf rice is formed through hybridization of the male parents and the female parents, the leaf color, glume flower cluster growth, glume flower color and awn character of the rice are combined to form various characters, the effects of leaf watching, flower watching and ear watching are good, and the dwarf rice is suitable for bonsai appreciation; the ornamental rice seeds can be obtained through first-generation hybridization, the batch production cost is low, and the production process is fast and convenient.

The invention relates to bacillus paralicheniformis HMF14, and the preservation number of the bacillus paralicheniformis HMF14 is CGMCC (China General Microbiological Culture Collection Center) No.30480. The bacillus paralicheniformis HMF14 has the advantages that the preservation number is CGMCC No.30480; the bacillus paralicheniformis HMF14 disclosed by the invention can resist saline and alkaline, can antagonize fusarium oxysporum, hematoptera graminearum var. Graminearum and xanthomonas brassicae specialized wheat at the same time, also has a poisoning effect on pratylenchus agilis and paenchus calcarinus, and can be used for effectively preventing and treating wheat take-all and wheat black glume disease.
