Resumo: The effect of crude xyloglucan (XG) preparations from jatobá (Hymenaea courbaril var. stilbocarpa (Hayne) Y. T. Lee & Langenh.) seeds on Arabidopsis thaliana (L.) Heynh. root system development was investigated. The XG extracts exerted a dual effect on root system development by slowing down root growth and improving lateral root formation. These observed morphological changes were not due to oligosaccharides that could be generated following hydrolysis of the XG polymers, since XG hydrolysate induced a drastic inhibition of the overall growth process of the Arabidopsis thaliana seedlings. Histochemical test of GUS gene expression assay performed on seven and 14-days-old transgenic Arabidopsis thaliana plants carrying the CycB1;1-GUS fusion indicated that the improvement of the lateral root development by jatobá XG extracts was not correlated with the expression of this cell cycle marker gene in the root system. A potential agricultural application of jatobá seeds XG extract is discussed.
