These hydrolysis products are translocated across the scutellum by a number of secondary active carrier systems. The second structure intimately involved in regulating endosperm reserve mobilization is the scutellum. Such mobilization and transport are accomplished by co-ordinating activities of the aleurone and scutellum. Analysis of nutrient transporters in the scutellum during cereal grain germination is a neglected area of research, particularly at the molecular level. The amount of this protein decreased in the scutellum, but increased in the aleurone layer during and after germination. Tissue prints localized transcripts to the scutellum or the embryo axis, depending on the stress applied. Scutellum with similar colouring to that of the thorax, the mid lobe with six bristles and the lateral lobes with four. The products are then transported via the scutellum to the embryo. This antigen was already present in dry grains, its abundance decreased in the scutellum and increased in the aleurone layer during and after seed germination. Cracks were also frequent in the scutellum, but rare in the embryo axis. In all the twelve cracked kernels inspected, thin cracks were observed around the scutellum inside the endosperm tissue. The breakdown products are then transported to the growing seedling by the scutellum. However, this expectation is not supported by measurements of peptide and amino acid transport rates across the scutellum in these different cereals. Mesonotal integument yellowish brown with brown scales, scutellum dark brownscaled. In addition, we evaluated the possibility that the large number of starch granules in the dormant scutellum had a causal association with the dormant state. The thorax and scutellum are black and somewhat polished; the humeri are lightcoloured. In practice, both peptide and amino acid transport across the scutellum can occur simultaneously, but peptide transport predominates early in the germination process. The golden-scaled scutellum and the distinct pale band on the apex of the hind tibiae distinguish it at once. The inserted image illustrates seed parts: aleurone layer (al), scutellum (sc) and starchy endosperm (en). The source of hydrolytic enzymes that digest starchy endosperm reserves is largely from both the scutellum and the aleurone. |
