| 摘要 |
The present invention relates to Brassica sequences comprising shoot apex-preferential promoter activity. Provided are recombinant genes comprising the shoot apex -preferential promoter operably linked to a heterologous nucleic acid sequence, and cells and plants comprising the recombinant gene. The promoters can be used to alter gene expression specifically in the shoot apices and to optimize shoot growth or shoot architecture, improve the resistance to pests and pathogens, improve the tolerance to abiotic stress, confer herbicide resistance, alter the flowering time or improve yield of a plant. |
