A group led by British-born plant scientist Stephen Long is trying to improve the ability of plants to harness energy from the sun. Their aim is to turbocharge photosynthesis,

when it comes to photosynthesis, which hints that if you can find a way to ramp it up,

In 2006, Long and his colleagues described how climate-change experiments have shown that rising atmospheric levels of carbon dioxide lead to higher rates of photosynthesis in plants.

More than 100 different proteins play a role in photosynthesis interacting in countless different permutations, Long says.

which ones could boost photosynthesis through trial and error would take years. But there is a shortcut: supercomputers.

Long's team broke photosynthesis down into a long series of mathematical equations and fed them to the National Center for Supercomputer Applications in Illinois. The supercomputer whirred through the numbers and spat out a list of"best-bet

since photosynthesis does not vary much among plants. However, this is not the only way of increasing photosynthesis. Scientists are also exploring the idea that genes from the ancestors of modern-day plants might boost the ability of crops to harness the sun. It is well known that primitive plants known as cyanobacteria have a talent

for concentrating CO2 within their cells at levels that make photosynthesis more efficient. It is believed that plants lost this ability

when they transferred to the land 500 million years ago, because they did need not it.

and efforts to re-engineer photosynthesis succeed, Long admits it would take at least a decade to move these transformed plants from research settings to farm fields.

In the near term before colonists can construct greenhouses they will have to use artificial light from LEDS for example to power their plants'photosynthesis. NASA has conducted plant-growth research in microgravity aboard the International Space station (ISS) and in the Long Duration Exposure

Photosynthesis would halt immediately and most plants would die in a few weeks. Large trees however could survive for several decades thanks to slow metabolism and substantial sugar stores.

since the food chain in rivers/oceans would be disrupted by the end of photosynthesis so even canned tuna/salmon would be used up within a few weeks.

We need photosynthesis without it we all die. It seems you donã¢Â#Â#t know much about life.

#Substance in photosynthesis was in play in ancient, methane-producing microbesan international team of researchers led by scientists at Virginia Tech

and the University of California Berkeley has discovered that a process that turns on photosynthesis in plants likely developed On earth in ancient microbes 2. 5 billion years ago long before oxygen became available.

They found that the protein thioredoxin which plays a major role in contemporary photosynthesis could repair many of the organism's proteins damaged by oxygen.

and photosynthesis are contributing to understanding the ancient process of methane formation Buchanan said. It is an excellent illustration of how a process that proved successful early in evolution has been retained in the development of highly complex forms of life.
