Patent number: 8889949Abstract: The present invention relates to a method for increasing resistance of monocot plants against abiotic stress which comprises a step of transforming monocot plants with a recombinant plasmid containing a fused gene (TPSP) of trehalose-6-phosphate synthetase (TPS) gene and trehalose-6-phosphate phosphatase (TPP) gene to express the TPSP gene while maintaining normal growth and development characteristics. The present invention can increase the resistance of monocot plants against various stresses so that it can greatly contribute to the improvement of production and quality of valuable agricultural crops. The present invention also relates to a transgenic monocot plant, plant cell, or protoplast transformed with a nucleic acid encoding an enzyme for trehalose biosynthesis, under control of an inducible promoter, that increases tolerance to low temperature, salt, and water stress.Type: GrantFiled: January 3, 2007Date of Patent: November 18, 2014Assignees: Cornell Research Foundation, Inc., Myongji University Industry and Academia Cooperation FoundationInventors: Ray J.

Patent number: 6929199Abstract: Porous ceramic particles can be fragmented by generating a gas inside the pores at a sufficient pressure to cause the particles to be fragmented. The preferred way of generating the pressure is by immersing the particles in a liquid that at ambient temperatures and pressures is a gas until the liquid is absorbed into the pores and thereafter rapidly changing the conditions such that the liquid becomes a gas resulting in explosive fragmentation of the ceramic particles.Type: GrantFiled: January 17, 1997Date of Patent: August 16, 2005Assignee: Saint-Gobain Ceramics & Plastics, Inc.Inventors: Ajay K. Garg, Michael D. Kavanaugh
