1 The aleurone grains of ungerminated seeds contain hydrolases.

2 Aleurone layer The outermost protein rich layer of the endosperm grass fruits ( e . g . cereal grains ).

3 Aleurone layer The outermost proteinrich layer of the endosperm of grass fruits ( e . g . cereal grains ) .

4 The development and ultrastructure of aleurone layer transfer cell in buckwheat( Fagopyrum esculentum Moench)were studied by using electron microscopy.

5 At germination, the embryo produces gibberellin, which stimulates the aleurone layer to synthesize enzymes, especially amylase.

6 Metabolic activity quickly develops in the cells of the embryo and the aleurone layer.

7 These enzymes are synthesized at the expense of reserve proteins mobilized in the aleurone vacuoles.

8 In grasses, the starch in the endosperm is broken down by enzymes synthesized in the aleurone layer in response to gibberellic acid from the embryo.

9 Many genes are involved in the formation of anthocyanin pigments in the aleurone.

10 The enzymes are synthesized from the amino acids supplied by breakdown of ALEURONE GRAINS.
