- Trigalacturonic acid, (α-1,4 galacturonotriose) is derived from pectin or pectic acid by enzymatic or partial acid hydrolysis (Combo, 2012). It is used in galacturonic acid metabolism research as a substrate to identify, differentiate, and characterize endo- and exopolygalacturonase(s), and gluconase(s) (Jayani, 2005). The addition of very short fragments of homogalacturonan, tri-galacturonate, and tetra-galacturonate oligosaccharides, restores development in dark-grown, de-etiolated seedling mutants, suggesting that they are unable to generate de-methylesterified pectin fragments. A model of spatiotemporally separated photoreceptive and signal-responsive cell types has been proposed, that contains overlapping subsets of the regulatory network of light-dependent seedling development (Sinclair, 2017).
