An efficient Agrobacterium-mediated soybean transformation method using green fluorescent protein as a selectable...

Area of Science:

• Plant biotechnology
• Molecular biology
• Genetics

Background:

• Genetic transformation is crucial for soybean gene study and breeding.
• Conventional methods using chemical markers are labor-intensive and time-consuming.
• Visual markers can streamline the identification of transgenic plants.

Purpose of the Study:

• To develop an efficient method for soybean transformation using a visual selectable marker.
• To reduce the time and cost associated with identifying transgenic soybean lines.
• To enable early detection and selection of transgenic soybean plants.

Main Methods:

• Utilized green fluorescent protein (GFP) as a visual selectable marker in soybean transformation.
• Visualized green fluorescence signals to detect positive transformants at early developmental stages.
• Applied recurrent selection based on fluorescence visualization throughout the transformation process.

Main Results:

• Successfully detected transgenic soybean lines early using GFP visualization.
• Reduced experimental costs and lab space by discarding non-transgenic plants at each stage.
• Enabled identification of positive transgenic seeds before planting for advanced homozygous line development.

Conclusions:

• GFP serves as an effective visual marker for early soybean transformation selection.
• The developed method offers a more efficient and cost-effective approach to soybean genetic modification.
• This technique provides a valuable reference for transformation studies in other plant species.
