This invention discloses a mango terpene synthase gene TPS4 and its applications, the nucleotide sequence of which is shown in SEQ ID NO:1. The amino acid sequence of the protein it encodes is shown in SEQ ID NO:2. The invention also discloses a recombinant expression vector containing the mango terpene synthase gene TPS4, a recombinant engineered strain, and the recombinant mango terpene synthase TPS4; and the application of the mango terpene synthase gene TPS4, its encoded protein, the recombinant expression vector, the recombinant engineered strain, or the recombinant TPS4 in regulating the synthesis of terpenoid compounds from geraniol diphosphate (GPP), neroli diphosphate (NPP), and farnesyl diphosphate (FPP). This invention is the first to clone and verify a terpene synthase gene TPS4 from the Sacred Heart mango genome, capable of simultaneously catalyzing the synthesis of monoterpenes and sesquiterpenes from three substrates: GPP, NPP, and FPP. It has broad application prospects and significant economic value.

The invention discloses application of 2-methylbutyric acid in prevention and treatment of postharvest diseases of mangifera indica. The diseases comprise mangifera indica anthracnose and mangifera indica stem-end rot. Wherein the pathogenic bacteria of the mango anthracnose comprise Asian colletotrichum gloeosporioides; the pathogenic bacteria of the mango stem-end rot comprise botryosphaeria dothidea and / or physosphaeria sojae. It is found for the first time that 2-methylbutyric acid has significant inhibitory activity on main pathogens after mango picking, and especially shows an efficient fumigation bacteriostatic effect on colletotrichum asiaticum causing mango anthracnose, botryosphaeria dothidea causing mango stem-end rot, and soybean mesotheca dothidea causing mango stem-end rot. 2-methylbutyric acid is mild in smell, so that the adverse effect on the original flavor of mangifera indica can be reduced to a greater extent.

The present utility model generally relates to a coffee product, particularly in the preparation method for producing a mango (Mangifera indica) seed drip coffee product. The preparation method for producing a mango seed coffee powder comprises steps of collecting, cleaning and washing 500 g mango seed kernels, sun-drying of mango seed kernels for about 7-9 days, getting the kernels inside of the mango seeds, roasting of the mango seed kernels in an oven for 45-60 minutes in 80-90 degrees Celsius, cooling of the roasted seed kernels for 5-10 minutes, grinding of the roasted seed kernels using a grinder, packaging and sealing of the mango seed coffee powder (10 g per pack), and brewing of the mango seed coffee powder through a hot water. The mango seed drip coffee powder is a great caffeine-free alternative to ordinary coffee, though it has a mildly roasted flavor with mild nutty undertones and is earthy and smooth.

The invention relates to the technical field of tissue culture in plant biotechnology, in particular to a rapid propagation culture medium and method for in-vitro regeneration of stem segments and petioles of Shuidong wikstroemia macrocephala. According to the specific technical scheme, a rapid propagation culture medium is based on 1 / 2 MS, and 0.5 mg / L of 6-BA, 0.2 mg / L of NAA and other components are added. According to the invention, the defect that leaves and other plants (such as rubus corchorifolius, olive kernel and neoparthenocissus nepalensis) cannot be regenerated by using the same formula is overcome, it is found and proved for the first time that the hormone composition only has a specific efficient induction effect on stems and petioles of Shuidong wikstroemia macrocephala, and the Shuidong wikstroemia macrocephala can be guided to rapidly differentiate calluses, so that the growth of Shuidong wikstroemia macrocephala can be promoted. And cluster buds can be rapidly differentiated from the calluses. According to the method, the propagation path is direct and efficient, and a core technology is provided for resource preservation and seedling raising of the Shuidong wikstroemia macrantha.

The application provides a high grafting crown changing method for Lecythis minor, which comprises the following steps of germplasm resource screening, scion treatment, mother stock cutting, grafting, stock removal from shade and post-grafting management, has high grafting survival rate and stock survival rate, short healing time and nursery time, and the scion is intact without damage, no dry burst, the stock survival rate is 95.2-97.2%, and the grafting survival rate is 95.2-98.4%.
