Current patents and future development underlying marker-assisted breeding in major grain crops

Area of Science:

• Agricultural Science
• Genetics
• Biotechnology

Background:

• Genomics and molecular markers offer novel tools for trait improvement in crops.
• Marker-assisted breeding (MAS) leverages genetic diversity from various sources, including wild relatives, to enhance commercial cultivars.
• Increasing global food demand necessitates improvements in crop quality and yield.

Purpose of the Study:

• To review current patents related to genes and quantitative trait loci (QTLs) used in marker-assisted breeding.
• To discuss the impact of intellectual property on the accessibility of advanced breeding technologies.
• To highlight the potential of MAS in improving major grain crops.

Main Methods:

• Review of existing literature and patent databases concerning marker-assisted breeding.
• Analysis of techniques for DNA isolation, amplification, and visualization.
• Examination of proprietary high-throughput systems and their associated patents.

Main Results:

• Basic MAS techniques are publicly available, while high-throughput systems are often protected by patents and trade secrets.
• High-throughput systems enable more efficient discovery of QTLs for economically important traits.
• An increasing number of patents for valuable genes and QTLs in crop improvement is anticipated.

Conclusions:

• Molecular markers and efficient detection systems are crucial for realizing the full benefits of MAS.
• MAS facilitates the reassembly and recapture of important genes lost during domestication, boosting crop production.
• Patent landscapes for crop genetics are evolving, impacting breeding strategies worldwide.
