"We have discovered that it is the plant equivalent of the nude mouse used in medical research."
"The plant has lost its 'immune system' and has done that to focus its energies on being able to germinate and grow quickly, rapidly flower, and set seed after even a small amount of rainfall.
"Its focus is on creating small flowers but large seeds and on getting these seeds back into the soil in time for the next rain.
"The plant has worked out how to fight drought -- its number one predator -- in order to survive through generations."
Professor Waterhouse, a molecular geneticist with QUT's Centre for Tropical Crops and Biocommodities, said scientists could use this discovery to investigate other niche or sterile growing environments where plants were protected from disease -- and space was an intriguing option.
"So the recent film The Martian, which involved an astronaut stranded on Mars growing potatoes while living in an artificial habitat, had a bit more science fact than fiction than people might think," he said.
Professor Waterhouse said the team's findings also have implications for future genetic research back here on Earth.
"Scientists can now know how to turn other species into 'nude mice' for research purposes. So just as nude mice can be really good models for cancer research, 'nude' versions of crop plants could also speed up agricultural research," he said.
Professor Waterhouse said the fact that the N. benthamiana variety from central Australia had doubled its seed size also opened the door for investigations into how N. benthamiana could be used commercially as a biofactory, as seeds were an excellent place in which to make antibodies for pharmaceutical use.
