Wheat is one of the most important food crops in China and worldwide. Wheat production is facing the stresses of different diseases including Fusarium head blight (FHB) which is more and more serious recently and leading to highly concerns. Unremitting efforts have been made on Fusarium head blight resistance breeding and comprehensive control technology development.
View Article and Find Full Text PDFF-box protein is a core component of the ubiquitin E3 ligase SCF complex and is involved in the gibberellin (GA) signaling pathway. To elucidate the molecular mechanism of GA signaling in wheat, three homologous GIBBERELLIN-INSENSITIVE DWARF2 genes, TaGID2s, were isolated from the Chinese Spring wheat variety. A subcellular localization assay in onion epidermal cells and Arabidopsis mesophyll protoplasts showed that TaGID2s are localized in the nuclei.

- Researchers used Diversity Arrays Technology (DArT) markers to study the genetic diversity of 111 northern Chinese wheat cultivars (lines), finding 1637 of 7000 markers to be polymorphic.
- The analysis revealed two major genetic groups (1RS/1BL type and non-1RS/1BL), along with various subgroups and geographic clustering among the genotypes.
- Overall, the findings are important for improving wheat breeding in China by aiding in the selection of crossing parents and establishing heterotic groups.
Article Synopsis
- The study focuses on identifying genes and markers for yield traits in common wheat to enhance breeding through marker-assisted selection (MAS).
- A meta-QTL analysis revealed 55 MQTLs, with 12 significant ones identified across various chromosomes in wheat.
- The findings suggest that important genes like Rht and Vrn play a key role in yield traits and that meta-QTL analysis can improve the precision and efficiency of breeding efforts.
