Abstract: When only roots of 13-d-old sorghum (Sorghum bicolor) seedlings were heat-shocked at 45℃ for 4h, some abnormal proteins were detected in the leaves that were not directly heat--shocked. The molecular weights of these abnormal proteins are around 80kD, 70kD, 33kD and 17 kD, respectively. For 6-d-old soybean (U.S. soybean) seedlings, when only their roots were heat-shocked at 40℃ for 3h there are at least two abnormal proteins (60 kD and 17 kD) to be obviously detected in their leaves. These abnormal proteins are named heat-shock effect proteins (HSEP). Meanwhile, a comparison of heat-shock protein and HSEP in their distribution of sizes of molecular weights has been made. A possible pathway in which the abnormal proteins could be induced is discussed. In addition, a possible physiological function of heat-shock proteins was also investigated, using a protein synthesis inhibitor, cycloheximide.
