Transgenic Cotton: From Biotransformation Methods to Agricultural Application

Area of Science:

• Agricultural Biotechnology
• Plant Science
• Genetics

Background:

• Transgenic cotton represents one of the earliest commercially successful genetically modified crops globally.
• Rapid adoption by farmers worldwide since the mid-1990s highlights its perceived value.
• Key benefits include reduced pesticide application, yield enhancement, environmental protection, and cost savings.

Purpose of the Study:

• To review the development and adoption of transgenic cotton.
• To highlight the primary methods used for genetic modification.
• To identify the dominant traits in the commercial transgenic cotton market.

Main Methods:

• Agrobacterium-mediated genetic transformation is the predominant technique for creating transgenic cotton.
• Pollen tube pathway-mediated transformation is also employed, notably in China for commercial breeding.
• Development of traits such as disease resistance, abiotic stress tolerance, and improved fiber quality has been pursued.

Main Results:

• Transgenic cotton has demonstrated significant environmental and economic advantages.
• Insect resistance and herbicide tolerance are the most commercially successful traits.
• Diverse genetic modifications have led to various improved cotton varieties.

Conclusions:

• Transgenic cotton technology has been widely adopted due to its substantial benefits.
• The market is dominated by insect-resistant and herbicide-tolerant varieties, indicating farmer preference.
• Continued research aims to further enhance cotton's resilience and quality through genetic engineering.
