DAVAO CITY—Three modified crops, including rice, resistant
to common pests will hit the domestic market in the next three
years.
Other biotech crops are being tested in the Mindanao campus
of the University of the Philippines (UP).
“These are the things that we can expect in the field
of biotechnology in the Philippines,” said Dr. Eufemio
Rasco, a Cornell University-schooled plant breeder, in a presentation
before agriculture scientists and experts and students at UP
Mindanao here.
Rasco foresees the Philippines in a leading role in the application
of traditional biotechnology using new materials. He said the
domestic market would see the commercial production of a variety
of Khak Nuan papaya, genetically modified (GM) to resist the
common pest ringspot, as well as an eggplant variety modified
to resist fruit and shoot borers, and the GM rice called Golden
Rice.
He said the modified crops would add to the four already in
the market, the controversial Bt corn, soybeans, cotton and
canola.
“We can expect these three modified products to be commercially
produced in the next three years,” said Rasco, a professor
of plant breeding at UP Mindanao.
He said the private sector is “also talking about its
own multiple stacked genes in corn, about eight of them,”
despite the controversy generated by its well-publicized experiments
in Tampakan, South Cotabato, in 2002.
In UP here, Rasco has led the field experiments in sago, which
has multiple uses in food production, and the pitcher plant,
eyed mainly for its ornamental use. He said the experiments
have been done in the last 12 years.
From sago, a kind of palm, starch could be derived as flour
substitute in baking and other industrial uses, and lactic acid.
The pitcher plant, growing well in the northern hinterland of
this city, has its leaves forming like a pitcher.
He said he is also experimenting on a plant called nepenthes,
which exhibits the unique characteristic of being a cross between
a plant and an animal. “It grows like other plants would
but it also feeds on other plants, a different kind of ‘plant-animal’
hybrid,” he said.
The plant could become a new platform for genetic engineering.
“We may hijack its own sap to determine why it eats on
other plants, while growing as a plant,” Rasco explained.
Nepenthes is an ornamental plant, “and biotechnology
could help save this plant—endemic in the Philippines—from
extinction.”
“Yes, this is an endangered species,” he said.
“These are our achievements in plant biotechnology: seed
propagation media, hydropriming biology of flowering and seed
production, in-vitro cutting propagation, callus and regeneration,
plant growing media, acclimatization, selling of in-vitro seedlings
and selling of clones,” he added.
Contrary to common perceptions, however, “what we are
using here in the Philippines is still the traditional kind
of biotechnology, but we are using new materials,” Rasco
added.
“It’s an impression that we are using modern biotechnology,”
he said.
In developed economies, scientists use gene-splicing, or genetic
engineering and protoplast fusion, or, “in general, any
technique that forces unnatural or horizontal DNA transfer.”
Although modern technology also “uses DNA markers to
establish paternity, solve crimes and diagnose diseases, plant
breeding and studying evolution still [are a] part of traditional
biotechnology,” according to Rasco.
“Currently, traditional biotechnology dominates, contrary
to what is being impressed on the public,” Rasco explained.
“Application of modern biotechnology is still limited;
in a crop agriculture, for instance, out of about 250,000 plant
species, only four major crops were subject to genetic modification:
corn, cotton, soybeans and canola.”
He said current uses of traditional biotechnology are in food
processing and production, biomedical applications such as drugs
and vaccines, and in industrial applications such as cleaning
agents.
“The oldest is food processing and food production,
and, would you believe, wine is the first product and the microorganisms
are the first workhorses,” he added.
“Mind you, but we can be leaders in the world of traditional
biotechnology using new materials,” he said. “We
can only be followers in modern biotechnology.”
