Abstract: The present disclosure provides a cultivation method of morels and belongs to the technical field of cultivation of edible fungi. After nutrient contents that can be metabolized and utilized by morel mycelia are scientifically matched, sterilization treatment of exogenous nutrients is eliminated, and the exogenous nutrients are directly compressed for forming. Formed exogenous nutrient blocks and spawn is sowed and covered with soil, so as to realize a potential difference between “rich” and “poor” nutrients in a physical space. When the spawn germinate to form a mycelium network, the mycelia will enter a nutrient-rich exogenous nutrient area, secrete various extracellular enzymes to decompose and utilize these exogenous nutrient blocks, and transport them to a nutrient-poor mycelium network for storage, so as to complete nutrient assimilation and absorption, and reserve energy for later sexual reproduction.

Abstract: The present disclosure provides an identification method of two parents of a Nymphaea hybrid based on sequences of internal transcribed spacer (ITS) and matK, and belongs to the technical field of plant molecular identification. In the present disclosure, the identification method includes: based on Sanger sequencing, obtaining an ITS sequence of a nuclear genome fragment inherited from the two parents and a matK sequence of a chloroplast genome fragment inherited from a maternal line in the Nymphaea hybrid; subjecting ITS and matK sequences downloaded from a GenBank to strict screening, and establishing a database of the ITS and matK sequence of the Nymphaea; aligning ITS and matK sequences of the Nymphaea of the parents to be determined with respective database, and constructing a neighbor-joining tree based on a genetic distance; and checking specific loci to obtain information on male and female parents of the Nymphaea to be determined.

Abstract: The present disclosure relates to the prevention of osteoporosis and specifically relates to an application of xylan (polyxylose) in the preparation of drugs or food for preventing or treating osteoporosis. The present disclosure proves by utilizing high-purity xylan in animal experimentation that xylan significantly improves bone metabolism, increases blood vitamin D, PINP, and BALP levels, reduces blood CTXI and urine hydroxyproline levels, and reduces urinary calcium loss, thus providing the effects of inhibiting bone resorption and promoting bone formation. Compared with animals having cellulose, lignin, pectin, fructan, glucomannan intakes or having no dietary fiber intake, animals having a xylan intake have higher bone mass and bone density and better bone biomechanical properties. Xylan is suitable for further development into the drugs or food for preventing or treating osteoporosis.

Abstract: Anthranilate synthase allele fragments for increasing rice yields and uses thereof. A method of differentiating rice materials with a superior allele associated with high yield includes: (1) detecting a genotype of rice to be detected based on a specific gene fragment; where the specific gene fragmentOsASA1 is located in rice genome, and there are typically two allelic forms of OsASA1, OsASA1_a shown as SEQ ID NO. 1 and OsASA1_b shown as SEQ ID NO. 2; and (2) determining and comparing the average yield of a rice population with a genotype of homozygous OsASA1_b and that of a rice population with a genotype of homozygous OsASA1_a under the same growth conditions in different geographical regions. The rice population with the genotype of homozygous OsASA1_b shows a higher average yield than the rice population with the genotype of homozygous OsASA1_a.
