Why in news
NASA researchers demonstrated that the plant *Nicotiana benthamiana* can be used as a bio-factory to produce medicines in space using the Cowpea mosaic virus (CPMV).
Background
The study utilized *Nicotiana benthamiana*, a relative of the tobacco plant, and the Cowpea mosaic virus (CPMV) to synthesize therapeutic proteins. This method was tested under simulated space conditions to facilitate in-situ medicine production for long-duration lunar and Martian missions.
Facts for Prelims
- S&TNicotiana benthamiana: A plant species used in biotechnology as a host for producing recombinant proteins.
- S&TCowpea mosaic virus (CPMV): A plant virus used as a vector for protein expression in plant-based systems.
- PostNASA: The US space agency responsible for the research on space-based pharmaceutical production.
For Mains
Q. Discuss how advancements in plant-based biotechnology and space medicine can facilitate long-duration human space exploration and reduce Earth-dependency.
Dimensions to cover in your answer
- Logistical bottleneck: High cost and risk of maintaining a continuous supply chain of perishable pharmaceuticals to deep-space missions.
- Biotechnological leap: Utilization of plant-based expression systems to bypass complex synthetic biology requirements in microgravity.
- Self-sufficiency paradigm: Transition from Earth-reliant life support to autonomous, in-situ manufacturing of critical healthcare resources.
