The invention provides a CCT domain-containing transcription factor ZmCOL3 and its coding gene, carrier, host bacteria and application, belonging to the technical field of plant genetic engineering. The CCT structural domain-containing transcription factor ZmCOL3 provided by the present invention has a better effect on regulating crop agronomic traits; the gene ZmCOL3 encoding the CCT structural domain ZmCOL3 and the locus containing the gene can be applied to crop genetics through vectors or host bacteria. Improvement; it has good practical application value and promotion value.
Description
technical field [0001] The invention relates to the technical field of plant genetic engineering, in particular to a transcription factor ZmCOL3 containing a CCT domain and its coding gene, carrier, host bacteria and application. Background technique [0002] Maize (Zea mays L.) is the cereal crop with the highest yield among the grain crops in the world. It has great potential for increasing yield and plays an extremely important role in agriculture. The three agronomic traits of maize flowering period, plant height and leaf number are important components of ideal maize plant design and play a vital role in improving maize yield. [0003] Corn originated in the tropical regions of Central and North America and is a typical short-day plant. The widespread planting of maize in temperate regions is the result of artificial domestication. The flowering of maize is significantly regulated by photoperiod. After the introduction of tropical and subtropical maize germplasm to th...
