UNIVERSITY PARK - Plant scientists at Penn State have become the first to product cotton directly from cell tissue instead of from seed. The technique is gaining worldwide recognition as a “breakthrough” in producing plants with superior genes. The cotton plants were regenerated from cellular structure known as callus tissue.

D.C. Are current U.S. Department of Agriculture regulations to prevent the in troduction and spread of contagious equine metritis too strict or not strict enough? "That’s the question we’re asking the horse industry," said John K. Atwell, deputy ad ministrator of USDA’s Animal and Plant He.alth Inspection Service. "There are some horse importers and breeders who would like to see USOA turn the. control of this veneral disease over to the horse industry,” he said. "Others would like to see ah industry—state cooperative program. Still' others are asking that USDA make horse import regulations even tighter than they now are." Contagious equine metritis ,isa bacterial disease, first diagnosed in 1977. Since then, USDA has restricted the killers, and pests,” he adds. Development of embryos -from ordinary (somatic) plant cells was first demonstrated with carrots in the 1950’5. “Using this and other methods, it is now possible to propagate over 250 species of cultivated plants,” Dr. Davidonis said. “Nearly 100 commercial facilities are using tissue culture to reproduce a variety of ornamental plants as well as food and forest crops,” she added. Geneticists can now develop new breeding lines of cotton with superior qualities from an ex ceptional plant. Then new plants can be generated directly from ordinary (somatic) cells. The challenge, it was pointed out, is first to produce outstanding plants by asexual cloning methods. The somatic cell cloning process was describing as “regenerating new crop strains much faster than the old-style cross-fertilization.” Plant tissue cultures are free of microorganisms and require only shelf space with little or no light. Plant tissue cultures are easy and economical to produce and can be grown year around. Culture conditions needed to regenerate tissue into cotton plants were discovered at Penn State during experiments into the way a new insecticide was metabolized or broken down by callus tissue. Careful control of growth regulators and other nutrients in the growth medium was vital in the research, it was noted. Davidonis believes the Penn State achievement in cloning cotton plants has been anticipated for a long time. Other major food and forage plants such as potatoes, corn, and alfalfa have been regenerated from tissue culture. She urged scientists to continue their efforts to regenerate soybeans—an increasingly vital farm crop. And she noted that biotechnical companies are “heavily into tissue culture.” comments requested movement of breeding age stallions and mares into the United States from countries known to be affected by the disease. These restrictions have prevented introduction and spread of the disease in the United States. However, the disease has been found in animals not known to have been bred. Also, it is supposed that many horses move from one country to another so that horses from af fected countries may be exported by unaffected countries.
