[Research progress on mutation by spaceflight in medicinal plants breeding]

Area of Science:

• Plant genetics and breeding
• Space biology
• Pharmacognosy

Context:

• Space breeding is a specialized field in China focusing on medicinal plants.
• Medicinal plants exhibit unique traits and advantages, though research is less extensive than in crops or vegetables.
• Current research covers biological traits, physiology, biochemistry, genomics, and chemical composition.

Purpose:

• To highlight the deficiency in genetic and breeding research for space-bred medicinal plants.
• To emphasize the need for follow-up studies on the genetic stability of space-bred medicinal plants.
• To explore the potential of space breeding for improving medicinal plant resources.

Summary:

• While space breeding in medicinal plants is advanced in China, genetic and breeding research, particularly on trait stability, remains insufficient.
• Studies have investigated various aspects of medicinal plants, including their genomics and chemical profiles.
• There is a need for in-depth breeding research to ensure the genetic stability of space-bred varieties.

Impact:

• Selecting genetically stable, high-quality space-bred medicinal plants can alleviate pressure on wild resources.
• This research is crucial for conserving valuable medicinal plant biodiversity.
• It will significantly contribute to the modernization of traditional Chinese medicine and the advancement of space botany.
