Journal ArticleDOI
High-velocity microprojectiles for delivering nucleic acids into living cells
TL;DR: In this article, small tungsten particles (microprojectiles) are used to carry RNA or DNA into epidermal tissue of onion and these molecules were subsequently expressed genetically.
Journal ArticleDOI
Delivery of substances into cells and tissues using a particle bombardment process
TL;DR: An acceleration device has been designed and constructed which can accelerate small tungsten particles to velocities of about 1,000 to 2,000 ft/sec, and it is found that these particles can penetrate cell walls and membranes and enter cells in a nonlethal manner.
Journal ArticleDOI

TL;DR: It is demonstrated that the particle bombardment process can be used to deliver foreign DNA into intact cells of maize and may provide significant advantages over existing DNA delivery methods for the production of transgenic maize plants.
Journal ArticleDOI
Transient expression of foreign genes in rice, wheat and soybean cells following particle bombardment.
TL;DR: In this article, a particle bombardment device was used to transfer foreign genes directly into the intact cells (with cell walls) of three important crop plants including rice, wheat and soybean by using β-glucuronidase gene as the reporter.
Journal ArticleDOI
Heterotrophic Nitrification in an Acid Forest Soil and by an Acid-Tolerant Fungus
TL;DR: It is suggested that nitrification in this soil is a heterotrophic process catalyzed by acid-tolerant fungi and not by autotrophs or heterOTrophs in nonacid microsites.
