Abstract
The coding sequence of Cyanobacterium Hemoglobin (CHB) gene was inserted into vectors pET-30a, pYES2 and pCAMBIA1300. Heterologous expression of CHB enhanced the growth rate of bacteria and yeast. Constitutive CHB over-expression in Brassica napus led to transgenic seeds early germination and enhanced the content of chlorophyll in transgenic seedlings. Under submergence conditions, the bioassays revealed that the CHB over-expression protected transgenic plants against prolonged waterlogging. These results suggest that CHB gene has the potential use in microorganism metabolic engineering, plant growth and system acquired resistance (SAR).
