Molecular insights into how a deficiency of amylose affects carbon allocation--carbohydrate and oil analyses and gene expression profiling in the seeds of a rice waxy mutant.

Background: Understanding carbon partitioning in cereal seeds is of critical importance to develop cereal crops with enhanced starch yields for food security and for producing specified end-products high in amylose, β-glucan, or fructan, such as functional foods or oils for biofuel applications. Waxy mutants of cereals have a high content of amylopectin and have been well characterized. However, the allocation of carbon to other components, such as β-glucan and oils, and the regulation of the altered carbon distribution to amylopectin in a waxy mutant are poorly understood.

Mapping of quantitative trait loci for fiber and lignin contents from an interspecific cross Oryza sativa×Oryza rufipogon.

Rice straw is always regarded as a by-product of rice production, but it could be a significant energy source for ruminant animals. Knowledge of the genetic variation and genetic architecture of cell wall traits will facilitate rice breeders by improving relevant traits through selective breeding and genetic engineering. The common wild rice, Oryza rufipogon Griff.

[Genetic analysis and mapping of high-tillering and dwarf mutant htd1-2 in rice].

Tillering is one of the most important agronomic traits of rice. In order to explore the molecular mechanism of rice tillering, a high-tillering dwarf 1-2 (htd1-2) mutant was isolated from the offspring of the indica rice (Oryza sativa L. ssp.

Analysis of genotype x environment interaction effects for starch pasting viscosity characteristics in Indica rice.

Milled rice (Oryza sativa L.) is composed of approximately 90% starch. The properties of starch have considerable effects on cooked rice palatability and consumer acceptability.

[Recent advances in molecular mapping and cloning of useful genes from wild rice and their application in breeding].

Wild rice has adapted to weather and unfavorable environments under natural selection. It has been well recognized as a natural gene bank that conserves a lot of specific genes presently not available for extinct in the cultivated rice. There is an urgent need to explore these specific genes.
