“…Altogether, our results corroborate the hypothesis that the presence of cell wall polysaccharides as storage compounds in cotyledons reflects an ancient functional transfer during evolution, as has been suggested by Buckeridge et al (2000). This hypothesis states that not only the polymer but also its related metabolism might have been subjected to similar selective pressure during evolution.…”

“…Isto porque, com a retomada da hidratação dos tecidos, várias enzimas hidrolíticas são ativadas ou sintetizadas de novo (BEWLEY;BLACK, 1994). Essas enzimas atuam na mobilização de reservas das sementes, que, em leguminosas, ocorrem principalmente na forma de galactomananas e xiloglucanas (BUCKERIDGE, 2000). As galactomananas são cadeias lineares de resíduos de manose unidas por ligações glicosídicas β-(1 4), nas quais resíduos de galactose são inseridos por ligações α-(1 6) (BUCKERIDGE et al, 2000).…”

As galactomananas ocorrem tipicamente na parede celular das células do endosperma de sementes de leguminosas, mas também estão presentes em sementes de espécies de outras famílias, como Compositae, Convolvulaceae, Annonaceae, Malvaceae, Palmae e Umbelliferae (GUZMÁN; HERNANDEZ, 1982).…”

“…The seeds of lettuce, tomato and many legumes are known to accumulate galactomannan or galactoglucomannan in their endospermic cell walls (Halmer & Bewley 1979, Buckeridge et al 2000a.…”
