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: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.
Project description:Four seed composition mutants (known as G15FN-109-1, G15FN-12-1, G15FN-23-3, and G15FN-54-3) were identified in a soybean fast neutron population developed in southern U.S. lines. The parent line for G15FN-109-1 is G00-3880, while the parent line for the other three mutants is G00-3213. Each mutant was compared to its respective parent line using CGH to identify the causative region/gene associated with the seed composition phenotypes.
Project description:Affymetrix Barley1 GeneChip microarray was used to study the transcriptome of two fast neutron barley mutants FN362 and FN363 allelic to characterized necrotic leaf spot 3 (nec3) mutants. PCR screening of the 21 genes at least two-fold down-regulated in mutants did not show any deletions in the genome of mutants and, thus, failed to identify a gene responsible for the nec3 mutant phenotype suggesting that either probe set for the NEC3 gene is not on the Barley1 GeneChip, or that the expression of wt NEC3 is confined to specific developmental stage or tissue type. Transcriptome of the two barley fast neutron mutants was compared to the transcriptome of parental variety Steptoe
Project description:CGH was used to compare induced structural variation among soybean fast neutron lines, developed in background M92-220. 114 different soybean fast neutron lines were hybridized against the parental reference genotype M92-220. The soybean tiling array consists of 700k probes, spaced at approximately 1.1 kb intervals.
