U.S. seed banks grow
in importance with food prices, war, economic woes|
By Kathleen Phillips
In an economic era focused on food prices, war and housing foreclosures, Dr. Peter Bretting turns to seed. Without seeds that support human existence, Bretting notes, few other issues would matter.
"It's important to the United States," Bretting said, "because pecans and sunflowers are about the only edible plants that originated here. We need to continue to gather and maintain these resources in gene banks for future supplies."
Bretting, national leader for the U.S. Department of Agriculture's plant genetic resources, was keynote speaker at the spring Distinguished Floriculture Lecture sponsored by the Texas A&M horticultural sciences department's Ellison Chair in International Floriculture.
From his office at the USDA-Agriculture Research Service in Beltsville, Md., Bretting oversees more than 20 seed banks in the nation — from a facility in Palmer, Alaska, that maintains samples from arctic and subarctic plants to the cotton and pecans in College Station and ornamental plants in Columbus, Ohio. More than 484,000 samples of about 12,400 plant species are kept, he said.
Worldwide, the plant gene bank system includes some 1.5 million unique samples.
"We have large collections of the major staples important to the United States and world agriculture," Bretting added. "More than one-fourth of these are grain crops."
Most of these seed were collected over the decades as U.S. scientists traveled on expeditions or traded with counterparts from other nations.
"We've done extensive collecting in past years through Tajikistan, Uzbekistan and Kazakhstan, for example, because that is where apples originated," he said.
As a result, the huge collection maintained by the U.S. is continually drawn on not only by the nation's seed and crop breeders but also other countries.
"Developing countries are dramatically increasing their requests for materials," Bretting pointed out.
The gene banks share collections with those who are trying to breed plants throughout the world. He noted that the plant genetic resources maintained in the U.S. are those parts of the plants such as seeds, cuttings, bulbs and pollen by which a plant propagates. Currently the system does not include storage of materials at the DNA level, though that might develop over the next 10 years, he added.
Bretting expressed concern that the history of sharing plant materials throughout the world has become less cooperative than in decades past.
"We're finding it more and more difficult to collect plant materials," he said. "Some countries have already closed the door. That day of free information exchange will never return, but hopefully the treaty (International Treaty on Plant Genetic Resources for Food and Agriculture) will help."
The treaty is under the auspices of the United Nation's Food and Agriculture Organization.
Bretting said the Internet, with its capability of using high-resolution photos and detailed databases, also is helping keep the supply-sharing system healthy.
He sees as a potentially threatening trend the static U.S. funds for operating gene banks and increasing costs for the labor intensive process that require plant materials to be grown to reproduce under a variety of specific conditions.
However, Bretting also said the increasing demands for the materials and "remarkable technical advances" will help keep the gene banks accessible.
found in simple plant nothing to sneeze at
By Kathleen Phillips
Whether a plant withers unproductively or thrives in salty conditions may now be better understood by biologists.
The cellular mechanism that controls salt tolerance has been found in the arabidopsis plant by a Texas AgriLife Research scientist collaborating with an international team.
Complex-N-glycan, a carbohydrate linked to a protein in plant cells, was previously thought to have no helpful function for plant growth and to cause certain allergies in humans, according to Dr. Hisashi Koiwa, lead author of the study in this week's Proceedings of the National Academy of Science.
"This gene has been considered non-essential or even a nuisance," Koiwa said. "People thought it was an allergen and couldn't find anything good it was doing in plants. So, it was thought of as not necessary for the growth or development of a plant."
However, the team discovered that this carbohydrate may, in fact, be responsible for a plant's ability to contend with salt water. The team's finding "significantly clarifies" the role of the gene and could lead to the development of food crops and other plants capable of producing well in areas with salty water, according to the science academy's journal reviewers.
Almost one-third of nation's irrigated land and half of the world's land is salt-affected, according to the U.S. Agriculture Department's Agriculture Research Service. Salt left in the soil after the water evaporates, the research service notes, means plants don't grow as well and, therefore, yield less.
The study used arabidopsis, a plant commonly used in labs because it grows quickly and has a relatively simple, well-known genome.
The researchers applied salt to the growing plants and then examined sick plants, or those that appeared salt sensitive.
"We had to study the diseased status of the plant to understand its health," Koiwa said. "We looked for sick plants in the lab to find out why they were that way."
He said the finding may help plant breeders look for this gene as they cross plants in order to develop varieties less affected by salt.
El Paso selected to host statewide Arbor Day celebration
Texas Forest Service
Trees in El Paso? To the outsider, this may seem like a reasonable question. But El Paso natives have long known that the desert is home to a unique variety of trees — and they are ready to show the rest of the state they are "Tree Amigos."
El Paso has been selected as this year's host of the state's official 119th Arbor Day celebration on April 25. The day will begin with a ceremony at 10 a.m. at Veteran's Park. James Hull, state forester and director of the Texas Forest Service, will be Master of Ceremonies.
"Arbor Day is the day we set aside to celebrate the value of trees and the positive ways they contribute to our communities and environment," Hull said. "El Paso was selected as this year's host city to honor the tremendous advancements in its urban forestry programs in recent years."
During the celebration, El Paso will be recognized as a Tree City USA for the first time, a designation made by the National Arbor Day Foundation. In addition, the state winners of the 2006 and 2007 Arbor Day Poster Contests, reigning from the same El Paso elementary school, will be honored.
The West Texas Urban Forestry Council, located in El Paso, is "Bringing Back the Green" to the El Paso region by encouraging residents to plant trees, which specifically benefit desert environments by providing shade and helping conserve water. Individuals interested in planting trees in El Paso or in any location across the state can go online to the Texas Tree Planting Guide at http://texastreeplanting.tamu.edu/ to find the types of trees best suited for different areas of Texas.
"It's not just about beautifying yards and streets, but just as much about teaching people how to strategically use trees to improve air quality, reduce erosion and reduce energy consumption," said Oscar Mestas, El Paso's urban forester for the Texas Forest Service. Communities across Texas can recognize Arbor Day by celebrating the ways that trees enrich our lives and the environment. For information about ways to celebrate Arbor Day in your community, visit the Texas Forest Service web site at http://texasforestservice.tamu.edu.
If ants are a pest in your house, scatter catnip flowers on windowsills and other entry points. While cats may be attracted to the fragrance of catnip, ants are repelled by it. Obviously, this isn't a good idea if you are allergic to cats.

Did You Know...
In olden times, honeysuckle was planted by the front door of houses where it was purported to repel fevers and bad spirits, planted by the barn it protected the livestock. It was considered a symbol of womanly love and brought luck to lovers. Mistletoe had similar qualities and was also considered a symbol of fertility and a potent healer. Many country people kept a sprig of mistletoe indoors all year believing "while mistletoe stays in the house, love also stays."
