Patent number: 6563021Abstract: Methods are disclosed to achieve an improvement in the characteristics and yield of cotton fibers. In one method, a cotton plant of the genus Gossypium in seed form or in growth stage is treated with a brassinosteroid. In another method, an ovule culture is prepared from a cotton plant of the genus Gossypium in a brassinosteroid-containing liquid medium. Cotton fibers with improved fiber characteristics are obtained from the cotton bolls of the treated plant or from the cultured ovules.Type: GrantFiled: January 17, 2001Date of Patent: May 13, 2003Assignees: Toyo Buseki Kabushiki Kaisha, Texas Tech UniversityInventors: Yoshihisa Kasukabe, Koichi Fujisawa, Susumu Nishiguchi, Yoshihiko Maekawa, Randy Dale Allen

Patent number: 6259003Abstract: Novel plant promoters isolated from cotton fiber tissues are provided. The plant promoters are located upstream cotton plant genes KC03, KC18, KC22, and Gh3, all of which are expressed in cotton fibers, and contain (a) DNA having the nucleotide sequence of SEQ ID NO:1, 6, 11, or 16. Also provided are plant expression vectors prepared by introducing the plant promoters into appropriate vectors; transformed plant cells prepared by introducing the plant expression vectors into host plant cells; transformed plants regenerated from the transformed plant cells; transformed plant seeds obtained from the transformed plants; and processes for producing transformed plants from the plant seeds.Type: GrantFiled: January 20, 1998Date of Patent: July 10, 2001Assignees: Toyo Boseki Kabushiki Kaisha, Texas Tech University of LubbockInventors: Koichi Fujisawa, Yoshihisa Kasukabe, Susumu Nishiguchi, Yoshihiko Maekawa, Randy Dale Allen, Song Ping

Patent number: 6046040Abstract: A method for producing glycoconjugate, which comprises the steps of:(i) binding a sugar residue to the side chain of a water-soluble polymer via a linker having a selectively cleavable linkage to give a primer, and bringing said primer into contact with an immobilized glycosyltransferase in the presence of a sugar nucleotide, to transfer a sugar residue of said sugar nucleotide to the sugar residue of said primer,(ii) elongating a sugar chain by transfer of plural sugar residues by repeating the step (i) at least once,(iii) removing, where necessary, a by-produced nucleotide or an unreacted sugar nucleotide, and(iv) repeating the steps (i)-(iii) where necessary and releasing the glycoconjugate by selectively cleaving the cleavable linkage in the linker, from the above-mentioned primer connecting the sugar chain elongated by the transfer of plural sugar residues,and a method for producing a sphingoglycolipid.Type: GrantFiled: July 28, 1998Date of Patent: April 4, 2000Assignee: Toyo Boseki Kabushiki KaishaInventors: Susumu Nishiguchi, Yoshihiko Maekawa, Shin-ichiro Nishimura, Kuriko Yamada
