简介：
Overview
This article presents protocols for transforming potato plants using Agrobacterium tumefaciens and Agrobacterium rhizogenes. The former results in complete transgenic plants, while the latter produces transgenic hairy roots that can self-propagate. Promoter activity is assessed through GUS staining in the transformed roots.

What is Agrobacterium-mediated transformation?
It is a method used to introduce foreign DNA into plant cells, resulting in genetically modified plants.
How does Agrobacterium tumefaciens differ from Agrobacterium rhizogenes?
Agrobacterium tumefaciens typically produces complete transgenic plants, while Agrobacterium rhizogenes generates transgenic hairy roots.
What is GUS staining?
GUS staining is a technique used to visualize gene expression by detecting the activity of the β-glucuronidase enzyme in transformed tissues.
Why is it important to study gene functions in plants?
Understanding gene functions helps elucidate their roles in plant physiology and can lead to advancements in agricultural biotechnology.
Can the transformed potato plants be propagated?
Yes, the transgenic hairy roots produced can self-propagate, allowing for further studies and applications.
