为了探究我国3个储粮生态区的大豆存储质量变化周期，指导不同储粮生态区大豆保质技术措施，收集了相关储存库点2014—2016年大豆品质数据，考察了大豆储存过程中粗脂肪酸值、蛋白质溶解比率的变化，分析了大豆品质指标与粗脂肪酸值、蛋白质溶解比率的相关性。结果发现：区域储存温度对大豆粗脂肪酸值影响较为明显，对蛋白质溶解比率影响较弱；在第五区中温高湿区储存大豆，其粗脂肪酸值增长与损伤粒、热损伤粒的增加及储存时间的延长有一定关系，蛋白质溶解比率与热损伤粒有一定的关系。综上，合理控制大豆的损伤粒、热损伤粒比例，对于控制其粗脂肪酸值和蛋白质溶解比率有较明显作用。 In order to explore the changing cycle of soybean storage quality in three grain storage ecological regions in China and guide the technical measures of soybean quality preservation in different grain storage ecological regions. Soybean quality data from relevant storage points during 2014-2016 were collected, the changes in crude fat acid value and protein solubility ratio during storage of soybeans were examined, and the correlations between soybean quality indexes and crude fat acid value, protein solubility ratio were analyzed. The results showed that regional storage temperature had obvious effect on crude fat acid value of soybean, but had little effect on protein solubility ratio. Storing soybeans in the fifth areas with moderate temperature and high humidity had a certain relationship with the increase of crude fat acid value and the increase of damaged grains, heat damaged grains, and storage time. There was a certain relationship between protein solubility ratio and heat damaged grains. In conclusion, reasonable control of damaged grain ratio and heat damaged grain ratio of soybean has obvious effect on controlling crude fat acid value and protein solubility ratio.

N6-methyladenosine (m 6 A) is the most prevalent modification in the eukaryotic transcriptome and has a wide range of functions in coding and noncoding RNAs. It affects the fate of the modified RNA, including its stability, splicing, and translation, and plays an important role in post-transcriptional regulation. Bones play a key role in supporting and protecting muscles and other organs, facilitating the movement of the organism, ensuring blood production, etc . Bone diseases such as osteoarthritis, osteoporosis, and bone tumors are serious public health problems. The processes of bone development and osteogenic differentiation require the precise regulation of gene expression through epigenetic mechanisms including histone, DNA, and RNA modifications. As a reversible dynamic epigenetic mark, m 6 A modifications affect nearly every important biological process, cellular component, and molecular function, including skeletal development and homeostasis. In recent years, studies have shown that m 6 A modification is involved in osteogenesis and bone-related diseases. In this review, we summarized the proteins involved in RNA m 6 A modification and the latest progress in elucidating the regulatory role of m 6 A modification in bone formation and stem cell directional differentiation. We also discussed the pathological roles and potential molecular mechanisms of m 6 A modification in bone-related diseases like osteoporosis and osteosarcoma and suggested potential areas for new strategies that could be used to prevent or treat bone defects and bone diseases., (© 2023 The Authors.
