英国威尔士植物育种试验站的科学家,在应用遗传工程技术培育耐寒作物品种方面取得显赫进展。该试验站的卡林斯博士最近研究发现,有一些耐低温霉菌可在-5℃～5℃的近雪层下繁茂生长。这些霉菌含有一种非常特殊的生化物质,使它们能在低温下生长。目前,他们已经掌握了将这些抗寒基因分离出来,并移植到高等植物中例如大豆中的技术,使英国农民也能 Scientists at the Plant Breeding Experiment Station in Wales have made remarkable progress in applying genetic engineering techniques to cultivate cold-tolerant crop varieties. A recent study by Dr. Karins at the station found that some low-temperature-resistant molds may flourish in near-snow at -5 ° C to 5 ° C. These molds contain a very special biochemical substance that allows them to grow at low temperatures. At present, they have mastered the technology of isolating these cold-resistant genes and transplanting them to higher plants such as soybeans so that British farmers can
