PR:PROJECT_TITLE                 	A combinatorial action of GmMYB176 and bZIP controls isoflavonoid biosynthesis
PR:PROJECT_TITLE                 	in soybean
PR:PROJECT_TYPE                  	Non-targeted high resolution MS of soybean GmMYB176-bZIP overexpressed hairy
PR:PROJECT_TYPE                  	roots.
PR:PROJECT_SUMMARY               	GmMYB176 is an R1 MYB transcription factor that regulates multiple genes in the
PR:PROJECT_SUMMARY               	isoflavonoid biosynthetic pathway thereby affecting their levels in soybean
PR:PROJECT_SUMMARY               	roots. While GmMYB176 is important for isoflavonoid synthesis, it is not
PR:PROJECT_SUMMARY               	sufficient for the function and requires additional cofactor(s). The aim of this
PR:PROJECT_SUMMARY               	study was to identify how the GmMYB176 protein complex affects the metabolome of
PR:PROJECT_SUMMARY               	soybean hairy roots using non-targeted high resolution mass spectrometry.

CO:COLLECTION_SUMMARY            	collected after 6 days for soybean hairy root transformation. After 21 days,
CO:COLLECTION_SUMMARY            	transgenic soybean hairy roots were collected for metabolomics
CO:SAMPLE_TYPE                   	Plant
#TREATMENT
TR:TREATMENT_SUMMARY             	No treatment, only effects of genotype compared to wild-type was investigated
#SAMPLEPREP
SP:SAMPLEPREP_SUMMARY            	For metabolomics analysis, frozen hairy roots were ground with liquid nitrogen
SP:SAMPLEPREP_SUMMARY            	and extracted in methanol:water (80:20, v/v). The samples were sonicated on ice
SP:SAMPLEPREP_SUMMARY            	water bath for 15 min followed by centrifugation at 11,000×g for 10 min at
SP:SAMPLEPREP_SUMMARY            	ambient temperature. The supernatant (350 µL) was dried under nitrogen gas. The
SP:SAMPLEPREP_SUMMARY            	dried pellet was dissolved in 200 µL of 50% methanol containing 10 µg caffeine
SP:SAMPLEPREP_SUMMARY            	as an internal standard and filtered through a 0.45 µm syringe filter.

MS:MS_COMMENTS                   	Thermo.raw files were converted to .mzml format using Protewizard , with peak
MS:MS_COMMENTS                   	peaking filter applied. Features were detected using the XCMS package with the
MS:MS_COMMENTS                   	centWave method (ppm tolerance 3.0). The signal to noise threshold was set to 5,
MS:MS_COMMENTS                   	noise was set to 5×105 and pre-filter was set to five scans with a minimum
MS:MS_COMMENTS                   	5,000 intensity. Retention time correction was conducted using the obiwarp
MS:MS_COMMENTS                   	method.. Grouping of features was set to those present in at least 0.1% of all
MS:MS_COMMENTS                   	samples (retention time deviation 5 s; m/z width, 0.015). The ‘fillPeaks’
MS:MS_COMMENTS                   	function was used with default settings. Zero values were imputed by 2/3 the
MS:MS_COMMENTS                   	minimum peak area value of a specific feature across all samples. PCA plots were
MS:MS_COMMENTS                   	obtained by log transforming the imputed XCMS peak area values, and ‘pareto’
MS:MS_COMMENTS                   	scaling in Rstudio. Volcano plots were also generated using the imputed XCMS
MS:MS_COMMENTS                   	peak area values. Compounds were identified by accurate mass, comparison of
MS:MS_COMMENTS                   	retention times to authentic standards or by accurate mass and also comparison
MS:MS_COMMENTS                   	of fragmentation patterns to MS/MS databases.
