Effects of the different waxy proteins on starch biosynthesis, starch physicochemical properties and Chinese noodle quality in wheat.

Unlabelled: Noodles are an important food in Asia. Wheat starch is the most important component in Chinese noodles. Loss of the waxy genes leads to lower activity of starch synthesis enzymes and decreased amylose content that further affects starch properties and noodle quality.

Identification and Evaluation of Wheat- Lines with Resistance to Powdery Mildew and Stripe Rust.

Wheat pathogens, especially those causing powdery mildew and stripe rust, seriously threaten yield worldwide. Utilizing newly identified disease resistance genes from wheat relatives is an effective strategy to minimize disease damage. In this study, chromosome-specific molecular markers for the 3S and 7S chromosomes of were developed using PCR-based landmark unique gene primers for screening wheat- progenies.

Characterization, Identification and Evaluation of Wheat- Chromosome Derivatives.

, a wild relative of wheat, harbors diverse disease and insect resistance genes, making it a potentially excellent gene source for wheat improvement. In this study, we characterized and evaluated six wheat- derivatives, which included three disomic additions, one disomic substitution + monotelosomic addition and two disomic substitution + disomic additions. A total of 51 PLUG markers were developed and used to allocate the chromosomes in each of the six derivatives to homoeologous groups.

Physicochemical properties of starch in relation to rheological properties of wheat dough (Triticum aestivum L.).

Wheat dough has been considered as a complex blend where gluten forms the continuous reticular skeleton and starch granules act as filling particles. The effect of starch on dough behaviors is not clear and the mechanism of starch affecting dough properties needs to be revealed. In this study, the micro-structure and physiochemical properties of starch from six wheat varieties (lines) with different dough properties were investigated, and the rheological properties of wheat dough were determined.

Characterization, identification and evaluation of a set of wheat-Aegilops comosa chromosome lines.

This study characterized and evaluated a set of wheat-Aegilops comosa introgression lines, including six additions and one substitution. A total of 47 PLUG markers and a set of cytogenetic markers specific for Ae. comosa chromosomes were established after screening 526 PLUG primer pairs and performing FISH using oligonucleotides as probes.

Identification and Expression Analysis of Wheat Genes.

The 14-3-3 gene family members play key roles in various cellular processes. However, little is known about the numbers and roles of 14-3-3 genes in wheat. The aims of this study were to identify numbers in wheat by searching its whole genome through blast, to study the phylogenetic relationships with other plant species and to discuss the functions of .

Agronomic Traits and Molecular Marker Identification of Wheat- Addition Lines.

is an important gene source for wheat breeding. Intensive evaluation of its utilization value is an essential first step prior to its application in breeding. In this research, the agronomical and quality traits of - additions B-G (homoeologous groups not identified) were analyzed and evaluated.

Cuticular Wax Accumulation Is Associated with Drought Tolerance in Wheat Near-Isogenic Lines.

Previous studies have shown that wheat grain yield is seriously affected by drought stress, and leaf cuticular wax is reportedly associated with drought tolerance. However, most studies have focused on cuticular wax biosynthesis and model species. The effects of cuticular wax on wheat drought tolerance have rarely been studied.
