Abstract:
A novel thermophilic endo-glucanase, nucleic acid encoding the endo-glucase, and uses thereof in converting ligocellulosic material to fermentable sugars.
Abstract:
The present invention relates to mutant gibberellin 2-oxidase (GA2ox) genes and uses thereof. In particular, the effective mutations disclosed herein can reduce GA2ox enzymatic activity to different extents, leading to various degrees of GA deficient yet beneficial agronomic traits in transgenic plants.
Abstract:
The present invention is directed to a method for the production of a transgenic plant of rice crop comprising the steps of infecting an immature embryo of rice crop with the genus Agrobacterium for transformation; co-culturing the infected embryo with a dicot suspension culture during the step of transformation; allowing the transformed embryo to grow into a callus in a selective medium comprising a sufficient amount of a plant growth hormone for the growth of rice crop; and allowing the cultured callus to regenerate root and shoot in a regeneration medium comprising a pre-determined amount of nutrients for the growth of rice crop. The invention is further directed to a transformed rice plant made by methods of this invention.
Abstract:
The invention provides DNA constructs and genetically engineered seeds for the expression of amylopullulanase in plant seeds such as rice seeds. Related methods are also provided for the production of sugars, modified starches, and high protein products, and use of the glutelin promoter in the methods.
Abstract:
The invention relates to a rice cysteine proteinase gene promoter, as well as vectors, transformed cells, and transgenic plants containing the promoter.
Abstract:
Disclosed are chill- or cold-tolerant plants and methods of making the plants. Also disclosed are methods for identifying a plant that is tolerant to chill.
Abstract:
Novel gibberellin 2-oxidase (GA2ox) genes were identified. Differential expression of GA2ox genes correlated with flower development, seed germination, tiller growth and other developmental processes. In addition, the early and increased growth of tiller and adventitious root and altered root architecture caused by overexpression of GA2oxs further suggest the pleiotropic role of GA2oxs in controlling growth and architecture in plants such as rice. GA2ox5, GA2ox6 and GA2ox9 were three genes encoding class C20 GA2oxs in rice. Mutants or transgenic rice overexpressing class C20 GA2oxs exhibited a broad range of mutant phenotypes, including semi-dwarfism, increased root system and higher tiller numbers that may favor grain yield. Mutations in the conserved domain III were found to affect the physiological activity of class C20 GA2oxs.
Abstract:
Disclosed are a transgenic plant and a transformed plant cell containing a heterologous nucleic acid that includes a sweet potato sporamin SPO promoter operably linked to a sequence encoding a polypeptide. Also disclosed are uses of the plant or cell.
Abstract:
A transformed tuberous plant cell or a transgenic tuberous plant containing a heterologous nucleic acid that includes a sweet potato sporamin promoter operably linked to a sequence encoding a polypeptide.
