Transcriptional regulation of an endo-β-mannanase gene influencing the germination process of Arabidopsis thaliana seeds

Mannans are hemicellulosic polysaccharides in the plant primary cell wall (CW). Mature seeds, specially their endosperm cells, have CWs rich in mannan-based polymers that confer a strong mechanical resistance for the radicle protrusion upon germination. In Arabidopsis thaliana seeds, the rupture of the seed coat and the endosperm are two sequential events
