Webb19 juni 2024 · Principle of Seliwanoff’s test. The reagent of this test consists of resorcinol and concentrated HCl. The acid hydrolysis of polysaccharides and oligosaccharides yields simpler sugars. Ketoses are more rapidly dehydrated than aldoses. Ketoses undergo dehydration in the presence of concentrated acid to yield 5-hydroxymethyl furfural. WebbAccumulation of lignin, visualized using phloroglucin HCl, was also observed in these tissues. The lack of GS1;2 resulted in reduced accumulation of lignin. Re-introduction into the mutants of OsGS1;2 cDNA under the control of its own promoter successfully restored the outgrowth of tillers and lignin deposition to wild-type levels.
