[Chinese Scientists Unravel the Mechanism of On-Demand Cold Resistance in Crop Flowering Stage] A research team led by Professor Xu Cao of the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, after eight years of continuous research, has discovered the first small peptide signal for low-temperature perception during the crop's growth period, thus unraveling the mechanism of low-temperature perception and signal transduction in crop pollen development. This mechanism elucidates how plants achieve precise and efficient defense against unpredictable short-term cold damage through "on-demand stress resistance," ensuring resilient and stable yields. The findings were published online in the international academic journal *Nature* on June 3rd (Beijing time). (Xinhua)

A chart showing the latest China Cotton Price Index (CC Index) data (June 4, 2026): The 3128B cotton price index was 17,899 yuan/ton (3128B is the benchmark for cotton futures delivery recognized by the Zhengzhou Commodity Exchange), up 75 yuan/ton, or 0.42%. The 2227B cotton price index was 16,329 yuan/ton, up 59 yuan/ton, or 0.36%, and the 2129B cotton price index was 18,212 yuan/ton, up 78 yuan/ton, or 0.43%. FX678's specially created chart provides a summary of the latest 30 trading days of the China Cotton Price Index (CC Index). (The China Cotton Price Index is published once per trading day, quoting prices in three denominations: 3128B, 2227B, and 2129B. The Zhengzhou Commodity Exchange (ZCE) stipulates that the benchmark delivery commodity for cotton futures is domestic cotton of '3128B' grade. The spot market cotton transaction price needs to be converted to the price of 3128B cotton using a specific formula. For example, research reports will state the price of cotton from a certain origin, and then calculate its equivalent price in 3128B.)

The Nikkei 225 index closed the morning session at 67,101.83 points, down 1.90%.
