Ecology of agroecosystems in relation to natural ecosystemsosystems are in existence. The transformation of these ecosystems into agroecosystems largely depends on cultural background, level of technology, and political decisions. In consequence, a wide variation of agroecosystem development, ranging from the simplest to the most advanced, exists today. Qui

Microbial germplasmon is genetically identical to the parent culture. Consequently, culture collections have been and are being established to conserve valuable germplasm important to economic, medical, agricultural, and scientific endeavors. Conservation technologies for microbial cultures are now an integral part of

Gene transfer in plantse used to combine (entire) whole genomes by fusing two plant protoplasts. These somatic hybridization procedures have been refined to allow the combination of nuclear and organelle genomes from different plant species. Transfer procedures also have been developed for moving genes from chloroplasts,

Alteration of the genome as a method to increase diversity in animal germplasm resourcesarmaceuticals, and creating models for the study of human disease. Low efficiency of gene insertion has restricted widespread use of the transgenic model to . and mice, though transgenic farm animals have been produced. Improved efficiency of gene insertion and improved regulation of gene function w
