“…Peptide length is considered to be closely related to biological activity (Cao et al, 2010;Gross & Zhao, 2014). Different peptide length-fractions of particular size ranges were fractionated by gel filtration chromatography, as a type of size exclusion chromatography.…”

“…Among these immunodulatory peptides, the enzymatic peptides from rice protein (RP) have been reported to exhibit strong immune activities in animal experiments as well as in clinical research (Takahashi et al, 1996;Takahashi, Moriguchi, Yoshikawa, & Sasaki, 1994;Wen et al, 2016). In addition, rice is one of the most important staple foods for more than half of the world's population, and provides approximately 60% of the food intake in some Asian countries (Cao et al, 2010;Gross & Zhao, 2014). The RP is rich in essential and balanced amino acids and has higher biological and protein values than other cereal proteins (Ochiai, Tanaka, Tanaka, & Taniguchi, 2016;Zhang & Wang, 2013).…”

2019) Purification and identification immunomodulatory peptide from rice protein hydrolysates, Food and Agricultural Immunology, 30:1, 150-162, ABSTRACTTo prepare immunomodulation peptides from rice protein hydrolysates (RPHs), trypsin was employed for enzymatic hydrolysis, and the immunomodulating activities of RPHs were studied using mouse peritoneal macrophage proliferation assay. The peptide fractions with the highest activity were further purified using macroporous adsorption resin, strong cation-exchange chromatography, gel filtration chromatography and reversed-phase high-performance liquid chromatography. The peptide sequence was identified as Tyr-Gly-Ile-Tyr-Pro-Arg (YGIYPR) by highperformance liquid chromatography electrospray ionization quadrupole time-of-flight mass spectrometer. Evaluating its immunomodulatory activity showed that YGIYPR enhanced the proliferation of macrophage RAW 264.7 cells in the range of 12.5-100 μg/mL, and even a minimum dose achieved good proliferation. The results demonstrated that the RPHs prepared by trypsin could serve as a source of immunomodulating peptides and the immunomodulatory peptide YGIYPR is a potential natural ingredient for manufacture of functional foods or health care products.

Super hybrid rice breeding is a new breeding method combining semi-dwarf breeding and heterosis breeding using germplasm and gene-environment interactions. This paper reviews the breeding strategies of super hybrid rice breeding in China, focusing on the utilization of heterosis of indica and japonica subspecies, construction of ideal plant architecture and pyramiding of disease resistant genes in restorer lines. To develop super hybrid rice, considerable effort should be made to explore genes related with high yield, good quality, resistance to pests and diseases, tolerance to stresses. Molecular breeding methods in combination with crossing techniques should be adopted in super hybrid rice breeding.

“…Comprehensive knowledge of the degradation of endogenous and exogenous genes during various processing procedures of different kinds of foods is required (Chen and others ). Steamed rice is the staple food in China, feeding more than 60% of the population and contributing nearly 40% of total calorie intake (Cao and others ). Rice noodles and rice crackers are popular snack foods, and sweet rice wine is a traditional fermented beverage in China.…”

In our study, we gained some information about the degradation of endogenous and exogenous genes during 4 foods processing, compared the different stabilities between endogenous and exogenous genes, and analyzed different effects of procedure on degradation of genes. In addition, the fragments of endogenous and exogenous genes about 200 bp could be detected in final products, except NOS terminator. As a result, we provided some base information about risk assessment of genetically modified (GM) food and appropriate length of fragment to detect GM component in processed foods.
