Tomato is a plant of the Solanaceae family and is an annual or perennial herbaceous plant. Tomato is one of the most cultivated vegetable crops in the world. Because it has the advantages of self-poll
Cucumber originates from the tropical rainforest areas at the southern foothills of the Himalayas. The botanical classification is Cucurbitaceae. Improving existing cucumber varieties through bioengin
Principle Arabidopsis thaliana is a cruciferous plant, a biennial herb, 7-40 cm tall. It is widely used in research on plant genetics, developmental biology and molecular biology, and has become a typ
In recent years, with the continuous improvement of transformation technology, the application of pollen tube pathway in agricultural molecular breeding has become more and more widespread. More than
Principle Gene gun method is also called microprojectile bombardment, parti-cle bombardment and biolistics. The gunpowder-detonated gene gun was first developed by Sanford et al. (1987) of Conell Univ
Principle Transformation of plant cells by Agrobacterium involves a series of complex reactions, including the attachment of Agrobacterium to plant cells, the release of signal molecules from plant ce
Expression of some eukaryotic proteins in prokaryotic host cells is efficient and cost-effective. However, many eukaryotic proteins synthesized in bacteria have low or inactive protein activity due to
The method of inserting the cloned foreign gene into a suitable vector and then introducing it into E. coli to express a large number of proteins is generally called prokaryotic expression. Prokaryoti
Cloning vectors are used to clone and amplify target gene fragments in host cells. This type of vector contains a replication signal sequence, which can replicate in host cells to obtain high-copy DNA
Since the Arabidopsis genome has been sequenced, when studying the promoter of a certain gene, primers can be designed based on the known gene sequence and the promoter sequence of the gene can be dir
