Thats why NASA is sending up a plant environment to the ISS. Its part of a program called Epigenetic Adaptation to the Spaceflight Environment– Accumulated Genomic Change Induced by Generations in Space (Plant Habitat-03). The concept is to follow succeeding generations of plants as they sprout, grow, live, and die in a microgravity environment.
Maturing Green in Low Gravity
Like human beings, plants progressed in Earths gravity and in ground-based environments. Exposure to the stress of spaceflight shows that things like an arabidopsis plant (previously grown on the station) really alter their genetics. Thats where Plant Habitat-03 comes in.
Plants should be in there, too. And, astronauts aboard the ISS have actually been growing gardens in space for years.

” Plant Habitat-03 will offer a better understanding of how the epigenome contributes to an organisms capability to adjust to environmental stress, in both present and subsequent generations,” stated Sharmila Bhattacharya, space biology program researcher in NASAs Biological and Physical Sciences Division at NASA Headquarters in Washington. “This is an essential insight into how astronauts could possibly grow repeated generations of crops in orbit as well as on the Moon or Mars to offer food and other services aboard future space objectives. The outcomes can also support the advancement of techniques for adjusting crops for development in severe environments in the world.”
Plants Adapting in Space
Plants develop all the time. Plant Habitat-3 will put them in microgravity and then watch them adapt to life in area. What epigenetic changes (that is, changes in gene expression) will occur?
Their seeds will return to area, along with brand-new seeds on their very first “objective” to the ISS. Eventually, the concept is to discover out simply how much the plant epigenetics change from spaceflight-affected specimens and compare them to new generations of plants flown in area.
Plant Habitat-03 is one of lots of projects that study how living things react to living in area. Previous ISS studies have looked at growing plants in space, for example, by studying how best to supply water and aeration to microgravity gardens.

Eventually, the concept is to discover out just how much the plant epigenetics change from spaceflight-affected specimens and compare them to new generations of plants flown in space.

Studies in Space Benefit Earth.
In addition to the space-based applications of the Plant Habitat-03 flight, there are Earth-based benefits. For something, our world has regions that are undergoing stresses from environment change. Discovering how tension impacts genetic expression in food crops might assist farmers in the world to adapt crops as conditions change across the continents.
