Abstract: A gene SiFAD2-1 controlling the oleic acid content trait in sesame and its SNP marker SiSNPFAD2-1 are provided. This gene is located on chromosome 4 of sesame and belongs to an incomplete dominant control gene; compared with a wild-type allele Sifad2-1. The high oleic acid mutant gene SiFAD2-1 has a 100% explanation value for a mutant trait of sesame high oleic acid mutant HO995 (i.e., this gene controls a high oleic acid phenotype). The present application can provide a certain theoretical basis for studying the regulation mechanism of high oil acid in sesame and other crops, and also provide a material basis and genetic resources for developing molecular assisted breeding technology for sesame, breeding new varieties with high oleic acid in sesame and even other crops.

Abstract: A sesame shattering resistance trait regulation gene Sihec3 and its application are provided. This gene is located on the third chromosome of sesame, is a recessive control gene, and fully explains the phenotypic variation of the shattering resistance trait. Genetic analysis of the shattering trait was conducted with F2 and F2:3 populations derived from a hybrid combination between a shattering resistance mutant M7 and normal shattering material. The research indicates that the seed shattering resistance trait in the tested population is a recessive trait controlled by a single gene. Based on the self-constructed sesame genome fine map and efficient gene mapping technology, the key gene Sihec3 and its allele SiHEC3 regulating the sesame shattering trait were cloned and compared. A corresponding gene marker named SSR1 for the sesame shattering resistance trait was dig. This invention provides a technical foundation for breeding new sesame varieties with shattering resistance trait.

Abstract: The present disclosure relates to a mosquito-killing lamp, including a shell. The shell is provided with a fan, an air inlet, an air outlet, a manual operation open-close mechanism, and an installation cavity and a mosquito storage cavity that are cut through. The air inlet, the installation cavity, the mosquito storage cavity, and the air outlet constitute an air duct; mosquitoes enter the mosquito storage cavity from the air inlet when the manual operation open-close mechanism is in opened state, and mosquitoes are prevented from flying from the mosquito storage cavity to the installation cavity when the manual operation open-close mechanism is in the closed state. The present disclosure has the advantages that mosquitoes fly out hardly, and the mosquito-killing effect is better.
