Researchers Genetically Modify Common Houseplant To Remove Air of Hazardous Compounds

An anonymous reader quotes a report from Genetic Engineering & Biotechnology News: Now, researchers at the University of Washington (UW) have genetically modified a common houseplant -- pothos ivy or devil's ivy -- to remove chloroform and benzene from the air around it. The modified plants express a mammalian protein, called 2E1, that transforms these compounds into molecules that the plants can then use to support their own growth. Small molecules like chloroform, which is present in small amounts in chlorinated water, or benzene, which is a component of gasoline, build up in our homes when we shower or boil water, or when we store cars or lawn mowers in attached garages. These compounds are too small to be captured by even HEPA air filters and exposure to each has been linked to cancer. Findings from the new study were published recently in Environmental Science & Technology.

I thought these plants already did this...

No? I thought these plants already did this... Does this protein increase capture and conversion rate?

Maybe the new plant is extra removing of chloroform and benzene beyond what a collection of normal "removing" plants can remove.

Re:

A better guess would be that some plants do it better than others, for example if they evolved in areas with higher concentration of organic gasses.

They likely isolated the genes of interest, clipped the DNA and plugged it into something better suited for the living room.

Does this plant smell like chloroform to you?

Re:I thought these plants already did this...

[msauve]

Yep. Whoop-de-shit. I haven't been attacked by chloroform since jr high science class, and then it was deliberate.

Re:

*SOME* plants remove benzene, though you're right that it does appear that golden pothos ivy is one of the top performers among common houseplants - so I would hope they're seeing a marked improvement to be worth mentioning. On the other hand, I'm not finding much reference to anything removing chloroform naturally.

Re:I thought these plants already did this...

There are quite a few houseplants that do indeed do this, but there is a bit caveat : they do it in tiny amounts. That is what gets left out of the various 'houseplants that clean the air' articles, they do not mention that you need huge numbers of them to get a measurable decrease in whatever it is they capture. So researchers that put together a plan that removes significant amounts AND only requires a small number of plants is pretty huge.

This plant contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Re:

In California, reproduction itself has been shown to cause reproductive harm.

There's lots of work for tree planters up here in Canada, how about we use trees that will suck up pollutants via genetically modified. :)

Re:

I think it removes breathable air for hazardous compounds, so you can get your toxins PURE.

Re:

[TheRealQuestor]

ummm wrong thread there Jackson.

Do you have to "water" it with gasoline?

[misnohmer]

If the plants uses those chemicals to grow, does that mean that if your house doesn't have sufficient amount of them you have to water it with gasoline? Or can it live on regular water and non-toxic stuff too?

Re:

[Gilgaron]

Plants use atmospheric CO2 as one of their carbon sources, this modification allows them to also incorporate these chemicals into their metabolism. It wouldn't supplant the entire metabolic chain, we're not that good at genetic manipulation.

Re:

[DarkOx]

This plant already had some existing metabolic process that uses those chemicals. Since the researches just added something - a new protein - without taking anything out my guess is that yes the plant can still live on its "normal" nutrient sources.

That said I would also assume it would be slightly less fit and require a little more inputs than unmodified individuals after all its making a protein it does not need.

Triffids

[LordWabbit2]

The day of the Triffids [wikipedia.org] is coming soon. One of favorite books btw.
Could they not have picked a plant with a more innocuous name, "devil's ivy" has an ominous ring as it is, never mind "genetically modified devil's ivy".

Title?

[CrimsonAvenger]

I'm assuming the submitter isn't a native English speaker, but would it be too much for the Editor to convert the title to something that passes for colloquial English?

Doesn't it ...

[aliquis]

... remove hazardous components from the air?

Then again if you do have a collection of hazardous things with some CO2 in it possibly also N2? a plant could remove that.
