Mycorrhizae |New Worlds Explored
Mycorrhizae | New Worlds Explored
In the Plant
Kingdom, the newest technologies, with New Worlds Explored, have traced the routes by which carbon
flows from roots to fungi and nitrogen flows the other direction. New
processes include isotopic labeling, spectroscopic analysis, and gene
characterization and expression measurements to develop working models for
carbon and nitrogen metabolism and transport which answer questions about their
mechanisms through Mycorrhizae in new worlds explored.
Science Daily (Nov. 15, 2012) — At least one-third of
the species that inhabit the world's oceans may remain completely unknown to
science. That's despite the fact that more species have been described in the
last decade than in any previous one, according to a report published online on
November 15 in the Cell Press publication-Current Biology-that details the
first comprehensive register of marine species of the world -- a massive
collaborative undertaking by hundreds of experts around the globe.
Science has spoiled us. Whether
it's a new planet that seems a lot like Earth, wireless technology innovations
or the cloning of extinct creatures, we have become accustomed to brilliant
minds bringing us new wonders. It's hard to understand them, or even keep up.
So we have decided to give
you a sneak peek at the future. This way, you have time to wrap your head
around the next big things, plus be the first to tell your friends.

“While
fewer species live in the ocean than on land, marine life represents much older
evolutionary lineages that are fundamental to our understanding of life on
Earth…”
Ward Appeltans of the
Intergovernmental Oceanographic Commission (IOC) of UNESCO
I’ve just read another article in New Scientist about a discovery
that plants communicate between them as if they had an Internet network and they use it to warn the other parts of the plant of diseases
and nutrition sources.
Scientists have observed that if a
plant is infected by some kind of disease it will transmit information to the
other plants of its network and those plants will not be so aggressively attacked
because of the warning to defend themselves.
Those networks, pictured above,
called mycorrhizae, are fungus that
colonize the host plants’ roots and look like white threads that hang off
all the roots. They are known for being used to exchange nutrients and
water. However, with the
new discoveries, plants and every part
of its environment work together for the benefit of all.
ScienceDaily (May 26, 2011) — The next agricultural revolution may be sparked by fungi,
helping to greatly increase
food-production for the growing needs of the planet without the need for
massive amounts of fertilizers according to research presented May 23 at the
111th General Meeting of the American Society for Microbiology in New Orleans.
"The United Nations conservatively estimates that by the year 2050
the global human population is expected to reach over 9 billion. Feeding such a
population represents an unprecedented challenge since this goes greatly beyond
current global food production capacity," says Ian Sanders of the
University of Lusanne, Switzerland, speaking in a session entitled "How
Microbes Can Help Feed the World."
Sanders studies mycorrhizal fungi, a type of fungus that
live in symbiosis with plant roots. When plants are symbiotic with these fungi, they tend to grow larger
because the fungi acquire the essential nutrient phosphate for the plant.
Phosphate is a key component of the fertilizers that fueled the Green
Revolution in middle of the 20th century that made it possible then for
agriculture to keep up with the growing global population.
Phosphate reserves are being
rapidly depleted. Increasing demand for the nutrient is driving up prices and
some countries are now stockpiling phosphate to feed their populations in the
future, according to Sanders.
While mycorrhizal fungi typically
only grow on the roots of plants, recent bio-technological breakthroughs now
allow scientists to produce massive
quantities of the fungus that can be suspended in high concentrations in a
gel for easy transportation.
Sanders and his colleagues are currently testing the
effectiveness of this gel on crops in the country of Colombia where they have
discovered that with the gel they can produce the same yield of potato crop
with less than half the amount of phosphate fertilizers. Additional information is available on New Worlds Explored.
