Can PGX Change the World?

Every entrepreneur has the vision they can change the world.  We at PGX believe we can change the world, for the better, one plant at a time!

Globally, every single day, Mankind strips away 35,000ha of forest.  Every day our remaining forests process 35,000,000 less tonnes of CO2; and every day the world’s remaining forests generate 93,000,000 less tonnes oxygen than they did the day before.

We’re destroying the lungs of our Earth.  (This is a key thesis in our headline PolyGenomX Video.)

To reverse this we must plant more trees than we cut down, but without the promise of short term gains humans are generally slow to act – even when that is in our own long-term interests.

Fortunately, PGX plants come with a promise of significant, short-term gains for anyone engaged in a plant-based enterprise.  30% increase in yield, or three harvests in place of two – all for no increase in inputs – promises huge increases in profits.  Strong incentives to use more of our plants.

Fortunately, they also come with incidental short-term gains for our environment.  An exponential 30%-50% increase in biomass means a 30%-50% increase in carbon dioxide extracted from our atmosphere, and a 30%-50% increase in oxygen, water vapour, and rain-forming nuclei.  This translates to increased cloud cover, increased rainfall, and decreased temperatures and, because they offer a more profitable alternative, may also reduce the destruction of old growth forests and native habitat.

Regardless of how sophisticated we are, at base we eat either plants or animals that eat plants. In the absence of plants neither coal, nor iron ore nor gold will sustain us.  Using more of our plants can.

How PGX’s Plants Reduce GHG (Greenhouse Gas) Emissions

Each hectare of polygenomic plants uses an average 100 tonnes more CO2 each year than the equivalent area of standard (diploid) plants.  Accordingly, we estimate that 10 million hectares of our plants will use 1 billion tonnes EXTRA CO2 every year.

If those plants are used for renewable energy, they prevent the release of a TOTAL 6 billion tonnes of “old fossil fuel carbon” into our atmosphere, or 1 billion tonnes MORE than can be hoped from the next best currently available renewable feed stocks.

Why?

Most plants grow by cycling CO2 into their leaves where sunlight powers chemical reactions that crack the CO2 into Carbon (which becomes plant sugars, the basic building blocks for all growth) and Oxygen (which is expelled as waste).

Standard plants are not 100% “carbon efficient”. One cycle in three or four they expend energy but fail to crack a CO2 molecule.  These energy-wasting cycles are called “photo-respiration”.

Our plants all but eliminate photo-respiration and so use up to 50% more atmospheric carbon for the same expenditure of time, energy, water and nutrients, accelerating growth and so using more-on-more carbon.

Faster-growing stress-tolerant disease-resistant plants which yield more in less time for no increase in inputs are more profitable and so many agricultural and silvicultural enterprises will progressively adopt polygenomic plants as their standard.

As fields and forests transition to our plants, more and more CO2 will be drawn from the atmosphere and locked into plant growth while more oxygen and moisture will be recycled into the atmosphere.

Who owns the genes?

In a  recent article by ABC reporters Eleanor Bell and Suzanne Smith titles “Future of food now a global battle” the issue of gene patenting was examined in the context of current research to uncover the genes responsible for stress and drought resistence (something that PolyGenomX has extensive knowledge of). Snippets of the report below, for the full article click here.

The race is on to find and patent all the known stress resistant and drought resistant plant genes in the world. The largest private and public seed, biotech and agrichemical companies and institutions have been granted at least 900 patents over plant genes that will be able to survive a world beset by climate change.

Scientists predict continents such as Africa will need crops that can survive at least a two degree rise in temperature, otherwise thousands of people could starve.

With predictions too that the world’s population will reach 9 billion by 2050, governments are also involved in building seed banks and working with big multinationals to find stress-resistant genes that can be scientifically altered to make plants more resilient.

According to Monsanto Australia’s Peter O’Keefe, Australia is in a unique position to benefit from and contribute to solving the global food shortage expected over the next few decades.

“We’re a big exporter on the world stage, so it’s important that we do our bit,” he said.

“But secondly, Australian farmers need to remain competitive, so we need to have access new technologies and particularly biotechnology to be able to increase production and remain competitive.”

But concerns about the rise in the number of patents being awarded to the top 10 multinational companies, who also have significant market share in seeds, chemicals and other essential farming stock, has prompted Liberal Senator Bill Heffernan to launch another inquiry into the issue of patents over genes.

The inquiry, to begin on June 30, will look at whether the patents granted already over plant genes give too much control to companies and institutions and how that control might affect farmers in the future.

A recent Senate inquiry into patents on human genes is expected to report in early June. A landmark court case in the US has also found patents were wrongly awarded over the breast cancer BRCA 1 and 2 genes; the company who owns the patents, Myriad Technologies, is appealing the decision. Currently Myriad Technologies charges women in the United States more than $3,000 for the breast cancer susceptibility test to see whether they carry the BRCA 1 and 2 genes. There is no second opinion tests allowed.

Senator Heffernan says, “In terms of national security and sovereignty, countries need to have control over their seed production not necessarily commercially controlled; now, if a company in America owns the absolute gene patent to a seed bank where does it leave countries like Africa (sic) and God knows where?”

Owning nature

But there is debate about whether the patents are actually granted over natural biological material. Supporters of the patents say the companies who have isolated the genes have done so by using an “invention” and therefore should be allowed control over the genes. Opponents believe the genes are natural biological material and no different when transferred to a lab environment and therefore should be judged as a “discovery” and not be allowed to be patented. The US District Court in the Myriad case found that the patents were null and void because the genetic material claimed in the patents was identical to that which exists inside the body.

Monsanto Australia – one of the top five multinational companies in the seed, biotech and agrichemicals business – says patents drive innovation. Executive director Peter O’Keefe says, “Without patents there’s no reward for commercial companies that spend a lot of time and effort on research and development, discovery and innovation. Patents are the key to ensuring that this research continues.”

He says Monsanto will be applying for more plant gene patents in the future and is happy to comply with Australian regulatory processes.

“We’re in the process of commercialising water-use efficient or drought tolerant corn in North America at the moment. It’s hypothetical but if we were able to bring that product to Australia then we would go through the regulatory process.”

Monsanto rejects Senator Heffernan’s belief that there is no inventive stage in the current plant gene patents.

“There’s a misconception that genes can be patented, that genetic material in its native state can be patented, and that’s incorrect. There has to be a lot more involved in the patent application than just picking a piece of genetic material and slapping a patent on it … it is about combining those genes with other genetic material, reinserting it into another plant. So the plants are lot more complicated than what we call genes or what we refer to genes.”(PGX note – this is specific to GMO’s, our plant technology recreates a natural process called polyploidy in which the plant replicates its genetic material in response to stress, polygenomic plants created through our unique technology are NOT GMO!)

Monsanto says it broadly licenses its developments so the technology is widely used and not restricted. The company says it also waives licence fees and is not charging royalties on some crops in Africa as a philanthropic exercise.

Global markets and the patent system

Geoff Tansey, trustee of the UK Food Ethics Council and author of The Future Control of Food, says global markets and the OECD nations have developed a patent system that benefits the big players and not the small operators and farmers.

Under the World Trade Agreement, all countries must sign up to the Trade-related Aspects of Intellectual Property rights or ‘TRIPS’ convention. The convention forces each country to protect patent owners’ rights. Trade sanctions can be issued if signatories fail to honour patent holders’ intellectual property rights.

 

The impact on science

The CSIRO has patents on plant genes in crops, and benefits from revenue generated by its patents. One of its scientists, Dr TJ Higgins, is optimistic about the future of crop biodiversity.

“We have access to 300 different crops at least for food. Intellectual property rights are probably concentrated on five or six out of that group so I don’t see it as a major threat … but from the point of food security for the future I don’t see it as playing a major role. It’s much more important that we get stuck into research and development to feed the nine billion people.”

Dr Higgins says being fearful of patents is an old-fashioned view.

“When people say that patents are the worst thing to happen to Australian agriculture I think that’s a simple view of the world and probably not all that realistic. It would be nice to go back to the old ways, but the world has changed,” he said.

One patent expert, Dr Richard Jefferson, a molecular biologist and founder of a not-for-profit research organisation CAMBIA, says patents are encouraging the push to monetise research outcomes in the public sector. He says this could have severe implications for the type of science performed in Australia.

While Dr Jefferson believes Monsanto’s research is a critically important area of investigation, because of Australia’s arid environment he says the public sector should pursue different research initiatives.

“In our rush to find one effective tool, we may neglect many other alternatives that are very effective,” Dr Jefferson said.

He says complex research involving changing agricultural eco-systems through pest introduction or crop rotations aren’t receiving adequate funding. These methods, developed in paddocks and laboratories alike, often require interdisciplinary research and are difficult to commercialise.

 

How Trees Boost Crop Yields & Food Security

A recent article in the BBC news sparked interest among PolyGenomX HQ, reporter Mark Kinver had this to say;

How Trees Boost Crop Yields & Food Security

The nitrogen-fixing roots of certain trees provide valuable nutrients to resource-poor arable land
Planting trees that improve soil quality can help boost crop yields for African farmers, an assessment shows.

Fertiliser tree systems (FTS) also help boost food security and play a role in “climate proofing” the region’s arable land, the paper adds. Researchers from the World Agroforestry Centre say poor soil fertility is one of the main obstacles to improving food production in Africa.  The results appear in the International Journal of Agricultural Sustainability.

“In Africa, it is generally agreed that poor soil management – along with poor water management – is most greatly affecting yields,” explained co-author Frank Place, head of the centre’s Impact Assessment team.

He said that despite chemical fertilisers having been on the market for more than half a century, farmers appeared reluctant or unable to buy them. “Therefore, there have been a lot of attempts to bring in other types of nutrients from other systems – such as livestock and plants” he told BBC News.

“We have been working quite a lot on what is broadly referred to as ‘fertiliser tree systems’.”
Although it has been known for centuries that certain plants, such as legumes, “fix” nitrogen in the soil and boost food crop yields, Dr Place said that the centre’s researchers had been looking to develop a more active management approach such as FTS.

“Some farms, for example in Zambia, where the farms are larger, it is possible to rest arable land and allow it to lie fallow,” he observed. “But in places such as much of Malawi, where population densities are higher, they cannot afford to fallow their land; so we came up with alternative management systems where they could intercrop the trees with the (maize).”

While the technique is not new, Dr Place said that some of the nitrogen-fixing species used by farmers were probably not the most effective.

For example, farmers in East Africa had been using Cajanus cajan (also known as pigeon pea).
“A lot of the nitrogen was being stored in the trees’ seeds; so there was an effort to use other trees that put a greater volume in the soil, such as Gliricidia sepium (one of its common name is mother of cocoa),” he said.

“A really nice thing about G. sepium is that we have been coppicing some of those trees for 20 years and they still continue to grow back vigorously.”

What is ‘nitrogen-fixing’?

The atmosphere consists of about 80% nitrogen, but plants cannot use it in this form certain plants, such as legumes, have bacteria growing in their root hairs that convert it into a form that plants can use this form of nitrogen is know as “green manure” and is a nutrient that helps plants, such as food crops, to grow (Source: World Agroforestry Centre). However, he acknowledged that there were a number of challenges that had to be addressed in order to maximise yields.
For example, some systems suggested planting rows of trees between rows of crops with mixed results.

“We realised that there were a few management problems with that sort of system – what tended to happen was that there was too much competition between the crops and the trees,” Dr Place explained.

“We developed a new management system where the trees were cut very low to the ground at the time you are planting the crop so then there was no light competition.

“The trees go into a dormant state when you cut them like this, so the root system is not competing straight away for the nutrients, so the maize is free to become established. “The trees only really start to come out out of the dormant phase when the maize is already tall.” Another challenge was to provide enough seeds in order to have mass-scale planting. He said that balancing the provision of high-quality seeds with large local engagement was another hurdle that had to be overcome.

But the rewards in improved yields were noticeable, he added. “Some of the studies have shown that in TFS across Africa as a whole, yields are doubling or more in two-thirds of cases.”

Where the systems were not delivering such good results, Dr Place said that scientists were looking to refine current practices and modify them to suit the local conditions.

‘Climate proofing’

As well as helping to boost yields, the use of trees in agriculture has other benefits – such as helping to “climate proof” agriculture land.

One example, Dr Place said, was the use of Faidherbia albida (common names include winter thorn and apple-ring acacia) in West African arable landscapes. “It has a deep penetrating tap root, and it can secure a good water supply even in dry years,” he explained. “Generally speaking, tree roots do go much deeper than crop roots, so it is recycling nutrients and water from deeper reaches. There are also studies showing that these roots act as conduits and bring up water to surface root systems (such as those belonging to crops).”

The editor-in-chief of the International Journal of Agricultural Sustainability, Professor Jules Pretty from Essex University in , said the study illustrated that there was a growing movement of agricultural innovations across Africa that were increasing yields and at the same time improving the environment.
“Trees and shrubs in agricultural systems seem to break some of the rules of agriculture – in this case, farmers are using shrubs to create a diverse rotation pattern rather than year-on-year maize,” he told BBC News.

“The trees fix nitrogen and improve the soil; the leaves can be fed to livestock; the crops then benefit greatly in subsequent years.”
