Background: Genetic variation in growth over the course of the season is a major source of grain yield variation in wheat, and for this reason variants controlling heading date and plant height are among the best-characterized in wheat genetics. Here we develop a biparental population segregating for major variants for both plant height and flowering time to characterize the genetic...

Genome-wide identification of the histone acetyltransferase gene family in Triticum aestivum. Conclusions: These results suggest that TaHATs may have specific roles in the response to viral infection and provide a basis for further study of TaHAT functions in T.

PacBio genome sequencing reveals new insights into the genomic organisation of the multi-copy ToxB gene of the wheat. fungal pathogen Pyrenophora tritici-repentis. While Ptr ToxA is encoded by the single gene ToxA, ToxB has multiple loci in the Ptr genome, which is postulated to be directly related to the level of ToxB production and leaf chlorosis. Although previous analysis has...

TaASN2 was the most highly expressed asparagine synthetase gene in the grain, with expression in the embryo much higher than in the endosperm, and higher in Spark than SR3 during early development. TaASN2 expression in the embryo of SR3 increased in response to sulphur deficiency at 21 dpa, although this was not observed in Spark. Asparagine synthetase and asparaginase gene...

Wheat ( Triticum aestivum L.) as one of the world ’ s staple crops is highly sensitive to heat stress, which can adversely affect both yield and quality. The observation of a high proportion of homeologous TaHsf gene groups suggests that the allopolyploid process, which occurred after the fusion of genomes, contributed to the expansion of the TaHsf family. Conclusions:...

analysis of WD40 proteins in wheat ( Triticum aestivum L.). However, the systematic identification and analysis of WD40 proteins have yet to be reported in wheat.. Among them, 39 and 46 pairs of TaWD40s were distinguished as tandem duplication and segmental duplication genes. The expression profiles of some TaWD40s in wheat seed development were confirmed through qRT-PCR technique.. The expression...

In the three resistant genotypes, 220 DEGs were associated with resistance.. In the pathogen, most genes showed increased expression between 2 and 4 dpi in all genotypes, with stronger levels in the susceptible host. A minor QTL associated with type II resistance was also identified by the same authors in the Chinese genotype Wuhan 1 on chromosome 2DL.. They also...

Molecular characterization and differential expression suggested diverse functions of P-type II Ca 2+ ATPases in Triticum aestivum L. Background: Plant P-type II Ca 2+ ATPases are formed by two distinct groups of proteins (ACAs and ECAs) that perform pumping of Ca 2+ outside the cytoplasm during homeostasis, and play vital functions during development and stress management. In the present study,...

Dissection of the multigenic wheat stem rust resistance present in the Montenegrin spring wheat accession PI 362698. Background: Research to identify and characterize stem rust resistance genes in common wheat, Triticum aestivum, has been stimulated by the emergence of Ug99-lineage races of the wheat stem rust pathogen, Puccinia graminis f.. The Montenegrin spring wheat landrace PI 362698 was identified as...

Features of the organization of bread. Background: The IWGSC strategy for construction of the reference sequence of the bread wheat genome is based on first obtaining physical maps of the individual chromosomes. Our aim is to develop and use the physical map for analysis of the organization of the short arm of wheat chromosome 5B (5BS) which bears a number...

Aquea et al., 2012). contradictory information related to physiological and biochemical responses of plants to excess B was reported (Liu et al., 2005). The generation of osmotic stress by toxic B levels was not precisely proven as stated by different researchers (Reid et al., 2004. Landi et al., 2019). KAYIHAN et al. Landi et al., 2014).. Also, toxic B led...

Morphometric and genetic variability among Mediterranean cereal cyst nematode (Heterodera latipons) populations in Turkey. Plant parasitic nematodes are responsible for annual economic losses of up to US$ 100 billion worldwide (Urwin et al., 1997. Nicol et al., 2003;. Subbotin et al., 2003. Dababat et al . Dababat et al., 2015). on knowledge of nematode species/pathotypes and their biological effects on...

Sowing dates;. Field experiment results indicated that under North Sinai environmental conditions, the significantly highest values of spike length, one thousand kernel weight and radiation use efficiency % were recorded by Gemmeiza-9 cultivar under early sowing date (October, 15). However, the highest values of spike weight, grain yield and dry biological yield were obtained when the same cultivar cultivated under...
