Abstract
Description
technical field
[0001] The present invention belongs to the field of plant biotechnology, in particular, the present invention relates to isolated DNA, which can direct the specific transcription and / or expression of nucleic acid operably linked downstream of it in plant anthers. In addition, the present invention also relates to expression cassettes and plants containing the DNA, and to applications of the DNA. Background technique
[0002] The exogenous DNA sequence is linked to a specific promoter to promote expression in the plant host, and the choice of the promoter type determines the time and location of gene expression. At present, some constitutive strong promoters are widely used in the field of agricultural biotechnology, such as the CaMV35S promoter and the corn Ubiquitin-1 promoter. , the improvement effect is often not obvious because the time (developmental stage-specific) or space (tissue-organ-specific) of the expression of the target gene cannot be well co...
