Genetic dissection for phosphorus uptake and utilization efficiency at seedling stage in wheat (Triticum aestivum L.).
The identification of germplasm with high phosphorus efficiency is helpful to the genetic improvement of wheat. In this study, a doubled haploid (DH) population was used to investigate the traits related to phosphorus efficiency and map relevant loci under different conditions. On this basis, the association panel was used to verify mapping results. The results showed that shoot phosphorus concentration (SPC) and shoot phosphorus uptake per plant (SPUP) decreased, while shoot phosphorus utilization efficiency (SPUE) increased under low phosphorus. Correlation analysis showed that seedling biomass and root diameter could provide reference for identification of phosphorus efficiency. Twenty-one stable loci related to phosphorus efficiency were detected by linkage analysis. Among these, 11 loci including QRC-4D, QSpue.7A.2, and QSpup.7A.2 haven't been reported yet. The physical interval of QRC-4D was detected by three seedling phosphorus efficiency indexes, along with five seedling morphological indexes and five adult agronomic traits, which explained phenotypic variation up to 31.18%. In the association panel, QSpue.7A.2 associated with SPUE was also detected by genome-wide association study. Gene analysis revealed two candidate genes related to phosphorus within QRC-4D and QSpue.7A.2. These results provide valuable insights into genetic improvement and gene mining aimed at improving high phosphorus efficiency in wheat.

期刊介绍：
Molecular Breeding is an international journal publishing papers on applications of plant molecular biology, i.e., research most likely leading to practical applications. The practical applications might relate to the Developing as well as the industrialised World and have demonstrable benefits for the seed industry, farmers, processing industry, the environment and the consumer.
All papers published should contribute to the understanding and progress of modern plant breeding, encompassing the scientific disciplines of molecular biology, biochemistry, genetics, physiology, pathology, plant breeding, and ecology among others.
Molecular Breeding welcomes the following categories of papers: full papers, short communications, papers describing novel methods and review papers. All submission will be subject to peer review ensuring the highest possible scientific quality standards.
Molecular Breeding core areas:
Molecular Breeding will consider manuscripts describing contemporary methods of molecular genetics and genomic analysis, structural and functional genomics in crops, proteomics and metabolic profiling, abiotic stress and field evaluation of transgenic crops containing particular traits. Manuscripts on marker assisted breeding are also of major interest, in particular novel approaches and new results of marker assisted breeding, QTL cloning, integration of conventional and marker assisted breeding, and QTL studies in crop plants.
