| Abstract: | Genomics, phytophysiology and biochemistry are important bases for crop improvement through genetic engineering. Based on the advances in the basic research, regulations on metabolic pathways have been realized in crops. The increases of oil content in rapeseed and vitamin E activity in the seeds of \%Arabidopsis thaliana\%, the provitamin A biosynthesis in rice endosperm and the enhanced tolerance of rice to low iron availability in alkaline soils are some of the successful examples which show the prospects of metabolic engineering in target\|oriented crop improvement. |
