Project description:Soybean fast neutron mutant lines were maintained to an advanced generation (ranging between approximately M6 and M11) and compared to their wild-type parent (M92-220-Long) using CGH to identify sequence deletions and duplications in the mutant plants.
Project description:Ten mutants with altered seed composition traits were identified in a soybean fast neutron population (Bolon et al. 2014). These mutant lines were maintained to an advanced generation (ranging between M5 and M9) and compared to their wild-type parent (M92-220-Long) using CGH to identify the causative region/gene associated with the seed composition changes.
Project description:Two high-sucrose/low-oil mutants (FN0176450/2012CM7F040P06/SRX826343 and FN0176450/2012CM7F040P05/SRX826351) were identified in a soybean fast neutron population (Bolon et al. 2014). These mutant lines were then advanced to the M3:7 generation and compared to thier wild-type parent (M92-220-Long) using CGH to identify the causative region/gene associated with high-sucrose/low-oil.
Project description:RNA-seq Data of Low Phytic Acid Soybean Mutant Lines and Wild-Type Parental Variety Across Different Developmental Stages and Seasons
Project description:We created stable transgenic soybean plants that express and secrete two different PI3P-binding proteins, GmPH1 and VAM7, in an effort to interfere with effector delivery and confer resistance. Soybean plants expressing the two PI3P-binding proteins exhibited reduced infection by the oomycete pathogen Phytophthora sojae compared to control lines. Measurements of nodulation by nitrogen-fixing mutualistic bacterium Bradyrhizobium japonicum, which does not produce PI3P, revealed that the two lines with the highest levels of GmPH1 transcripts exhibited reductions in nodulation and in benefits from nodulation. Transcriptome and plant hormone measurements were made of soybean lines with the highest transcript levels of GmPH1 and VAM7, as well as controls, following P. sojae- or mock-inoculation. The results revealed increased levels of infection-associated transcripts in the transgenic lines, compared to controls, even prior to P. sojae infection, suggesting that the plants were primed for increased defense.
