Project description:Soybean is one of the most economically important crops in the world. The cotyledon is the nutrient storage area in seeds, and it is critical for seed quality and yield. Cotyledon mutants are important for the genetic dissection of embryo patterning and seed development.Here, we characterised a soybean curled-cotyledon (cco) mutant. Compared with wild-type (WT), the entire embryos of cco mutant resembled the “tail of swallow”. To explore the molecular mechanisms underlying soybean cotyledon development, we executed RNA-Seq using the Illumina HiSeq2000 system.
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.

To explore the molecular mechanisms underlying soybean cotyledon development, we executed RNA-Seq using the Illumina HiSeq2000 system. Pods at 7DAF collected from WT and cco were analyzed by RNA-seq.
Project description:One short trichome mutant (family known by multiple names, including R59C46, FN0175946, and FNMN0409) was identified in a soybean fast neutron population (known as VP02 in Bolon et al. 2011). An advanced line of this mutant was compared to its wild-type parent (M92-220-Long) using CGH to identify the causative region/gene associated with the short trichome phenotype.
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.
