In recent years, my country's crude oil production and sales have increased significantly. However, due to factors such as rising international oil prices and weak domestic demand, the development of the oil industry has experienced a bottleneck period and serious overcapacity. Therefore, for the current production of petrochemical enterprises However, with the rapid growth of the national economy, the increase in energy demand and the increase in environmental protection requirements, higher standards have been put forward for power supply. Problems are analyzed and corresponding solutions are formulated to promote the healthy and orderly operation of the entire industrial system.展开更多

A search of the rice genome identi-fied 97 genes encoding WRKY proteins. Of these 97 WRKY homologs found in rice, 13 cDNAs encoding WRKY proteins were consequently isolated from a rice cDNA library con-structed from 4℃-treated shoots by probing for the con-served WRKY domain. Northern blotting analysis revealed that 10 of 13 OsWRKY genes were differentially regulated in plants that were treated by the four following abiotic stress factors: NaCl,PEG,cold (4℃) and heat (42℃). The resulting expression profiles exhibited great differences in both the manner and timing of their response to the four different abiotic treatments. The difference of gene expression profiles suggested the different physiological functions among the WRKY genes.展开更多
