grass.jpgThe EPA states that ‘using a commercial chainsaw-powered by a two-stroke engine-for two hours produces the same amount of smog-forming hydrocarbon emissions as driving ten 1995 cars about 250 miles each.'

In May of 2006, scientists at the Howard Hughes Medical Institute and the Salk Institute discovered a steroid pathway that controls plant height so that you may have a perfectly manicured lawn without ever moving or weed whacking. Farmers could greatly benefit from this because it can also be use to make crops grow larger, producing more food per acre.

How is this possible? Well, by disrupting the plants hormones called brassinosteroids, investigator Joanne Chory explains, that play a central role in the plant structure, they can turn plants into tiny dwarves. "Brassinosteroids have been found in every plant in which they've been looked for, expressed in most tissues from roots to flowers. In fact, the steroids and their accessory enzymes are conserved far into evolutionary history". Chory and her team found that animal enzymes can actually be used to activate the plant steroids.

Removing the brassinosteroids miniaturizes plants, but also effects the plants aging and reproduction. Chory explains that plants age differently from animals, one leaf at a time. Brassinosteroids promote this aging program because as she says, "When we don't have brassinosteroids in the plant, the leaves stay green, they don't turn yellow, and they also don't fall off."

Grass that has been altered to not grow anymore has some major benefits such as it would use less water, less fertilizer, stay green longer, never need moving and you can make it any height you would want. Golf courses benefit greatly from this since it's a daily chore to keep their greens green. Plus golfers would benefit from this by not having to tee off with a lawnmower chugging away 20 feet from you.

One major concern of theres is the modified genes spreading into the environment, but since the grass is no longer growing it shouldn't be able to make pollen, which should keep it from spreading. But will altering the length of the grass effect the ecosystem of animals and creatures that living in your yard?

How do you feel about this? Should they make this available to consumers right away as an attempt to cut down on carbon emissions? Or do you think it is wrong to be meedling with Mother Nature like this and we should push using more electric lawn mowers and push mowers to cut our grass.

    Great post, Tracey Shrier. Firstly, I am totally surprised to learn that using a two stoke engine could put out so much of hydrocarbon emission. Besides the smog problems that it adds to, just how much energy, fertilizers, pesticides, herbicides etc. get used in the upkeep of the grass. Eventually these chemicals find a way of getting into our food chain. Your post on NO-MO-GRASS is very encouraging and gives us hope that help may be on the way. The concept of interrupting/controlling plant growth by manipulating the presence of Brassinosteroids is very interesting. It seems like the biology of the plant is changed through this manipulation. As a scientists, I like this concept very very much. As for the question of this being a modified gene, even though I have no expertise in this field, in my judgment this is not akin to a DNA modification.per se. It is a modification in the sense that the gene that controls the hormone is suppressed/taken out. Even otherwise as is said in the article the plant does not produce any seeds and may not spread into the ecosystem, the impact on the ecosystem may be minimal. I don't have enough information to comment on what effect this grass may have on other animals and creatures that depend on the ecosystem of the grass. Minimum is my guess. I like the overall concept of engineering the grass growth. If successful, there are myriad of reasons that this new grass can have positive impact on our lives.

    The beneficial aspects of altering grass on the genetic level in order to potentially curb its notorious and far less environmentally-friendly traits has merit in theory, but I am still troubled by the Frankenstein aspect. When the genetic material of plant and animal DNA is altered in a laboratory rather than through the natural process of evolution and adaptation, I'm concerned that more startling environmental consequences can emerge. As it stands, the majority of our cotton/corn/soybean crops contain GMOs thanks to Monsanto's grip on industrial agriculture, and while that may not seem problematic on the surface, no one yet knows what long term issues it might cause. If history has taught us anything, it's that when you mess with Mother Nature, there is generally a price to pay.If anyone here has watched "King Corn", you'll know that GMO corn crops are impossible to keep separate from non-GMO crops planted in accompanying plots. Yes, you can plant natural borders around them, but the wind has a mind of its own. What ends up happening is that "pollen drift" from GMO hybrids contaminates (via cross-pollination) nearby non-GMO corn. The pollen from GMO plants contains genetically modified DNA, so when that pollen with modified DNA pollinates a non-GMO plant, the genetic modification is present in the new plant.Non-GMO farmers have lost entire fields of crops thanks to unintentional cross-pollination with genetically modified plants from neighboring farms. It's estimated that almost 30% of organic crops actually contain GMOs but testing is very expensive and left up to the discretion of the farmer/processor. I guess I'm drifting into another discussion altogether, so let me try to refocus on the grass issue. I take solace in the fact that we're not going to consume this proposed brassinosteroid-disrupted grass, but other critters out in the natural world probably will. And then, as the material makes its way through their digestive systems, they will leave little "deposits" throughout the yards and fields of our country. Then, rain will dilute those deposits and they will penetrate our soil and leach into our water supply and waterways. Before we know it, our fish will grow wings and viciously attack anything with a nose. Maybe I'm stretching things a bit, but for every action there's a reaction. Sometimes, I just don't think that scientists have their heads screwed on tightly enough. I'll stick with a push mower, thank you very much.

      I dunno. I'm a lazy kind of dude. Your facts and figures should scare me, but if I can take the easy way out, I will every single time. If the caterpillars on my property nibble my frankenstein altered grass and trigger a small ecosystem apocalypse everytime they poop, am I a horrible person to say that I can still manage to sleep okay? This is where I feel like the ugly greenwala duckling. Someone out there tell me why I'm not more afraid? I think I was dropped on the head as a little pup, so that may explain part of my problem. But seriously, GMO food? We're all eating it whether we like to admit it or not. You yourself said that 30% of organic crops are contaminated with GMO organisms, so even if your a turbo-green person and buy all organic, your probably still getting frankenstein crap in your bloodstream. We're dependent on scientists to do right by us. Doesn't look like we can trust 'em, though. But we gotta keep on living and hope that this crap doesn't take us down. Short grass will make my life better. I hate mowing. GMO food on the other hand I'm not so crazy about. I gotta admit that freaks me out.

    No offense Bob, but your laziness is why scientists are tweaking with things they shouldn't tweak with. We're always looking for the easy way out as a society -- I worry that that will ultimately be our downfall. Bob, if you'd like, I'll volunteer to cut your grass with my push mower -- I don't mind the extra exercise. Personally, I'd like to tie scientists' hands behind their backs since they keep getting us into problems that are really hard to fix. How hard is it to mow your grass, people? If you're so sick of the chore, then rip it out (since it wastes a lot of water anyway) and plant a xeriscape garden that requires a minimal amount of H20. Wow -- problem solved!

    Linda-
    I'm with you! xeriscape is the way to go. There are tons of plants on the market that require little water, grow short naturally and you can walk on it. If you can remove the grass altogether, consider DG, Decomposed Granite, as an option to a concrete patio. The push mower is the way to go but in my neighborhood the gas blowers are the things that tick me off even more! Do we really need them to push the leaves and grass into a pile? Aside from the air pollution the noise pollution is worse!

    Here we clone again! As much as the thought of a zero maintenance lawn does sound appealing, it just feels wrong. Linda, if you're offering mowing services, I have some grass that would welcome you with open blades....and it is not part of a science experiment. Here's a great link about xeriscape landscaping, which literally means "dry landscape" or "dry scene." There really ARE so many benefits because in addition to conserving water, we can conserve OUR energy since the plants require minimal maintenance!

    I so agree with every word written by Elizah Leigh. How many times do we need to repeat the mistakes of the past (i.e. alter our environment) before we will understand that we are the CAUSE that created the EFFECT?

    I'd like to find the person(s) who dooped so many people into believing that a green, nicely manicured, weed free lawn should be the standard for everyone living in America, regardless of your geographic location. It's akin to the standard set for women's bodies (the one that says we should all look like an emaciated model). But that's another topic...
    I live in a mixed grass prairie ecosystem. The plants that would grow best in my lawn would be the ones found in this ecosystem. By reintroducing these natural grasses and plants to my yard I can create my own mini ecosystem where the indiginous species in my environment can florish. The effort it takes to create this kind of lawn occurs in the planning and implementation, but once established, the result is a natural, self sustaining habitat that can provide a wealth of herbal remedies and foods. A side benefit are the butterflies, birds, and other living creatures that come with it. I am currently planning this type of "lawn" for my backyard, which will also include square foot gardens for vegetables that will be irrigated through the soil. Luckily I have a model garden to observe (one that surrounds a platinum LEED certified building). I also have access to 3,000 acres of mixed grass prairie that I hike in every other week with a naturalist. It is important to experience the environment you live in and to know some of the thousands of plants, insects and animals that you share this environment with. It increases the bond between you and the specific place you live in on this astounding planet...There is no place like home.

    I'm a huge fan and an active member of the less lawn movement but lots of folks don't know about a big giant lawn secret ! There's a non-genetically modified lawn that you don't need to mow because it just naturally grows slowly, rarely have to water or fertilize and can grow well in sun or shade. It's called Eco-Lawn and it grows great in all kinds of soils all over North America. It's a blend of seven fine fescues.Just lovely to walk on barefoot! It is truly a sustainable lawn.

    In Ohio Kentucky Blue Grass is the preferred lawn grass for its silky smoothness feel on the feet. Generally, Fescues are supposed to be a bit rougher. May be the fine fescues that you have mentioned are different. Yet, I need to see it and have a feel of it, to know if this is something that would be acceptable around here. I am going to check the site mentioned in your comments. If it is as good as have been explained, that will be a definite plus from the sustainability perspective.
