Mixed DP 7/8 Na galacturonans (α-1,4 galacturonoheptoses and octaoses), are derived from pectin or pectic acid, by enzymatic or partial acid hydrolysis. They are used in galacturonic acid metabolism research as a substrate to identify, differentiate, and characterized endo- and exopolygalacturonase(s), and gluconase(s). The addition of very short fragments of homogalacturonan 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.
