Endosperm morphology and protein body formation in developing wheat triticum aestivum grain



Endosperm morphology and protein body formation in developing wheat triticum aestivum grain



Australian Journal of Plant Physiology 8(1): 5-20



The development of wheat [cultivars Timgalen, Sun 9E and Penjamo] grain from intact plants and from detached ears growing in culture was studied by EM and light microscopy. Provided the sucrose concentration was at a level sufficient to maintain a normal rate of starch synthesis, the endosperm morphology of grain from cultured ears was essentially identical to that of endosperm from intact plants. If sucrose concentration in the culture medium was low (0.25%), some morphological abnormalities occurred in the endosperm near the crease and adjacent to the seed coat. The synthesis of storage protein in the endosperm is believed to occur largely on polyribosomes attached to endoplasmic reticulum even at the earliest stages of development. Protein bodies are always surrounded by a single membrane, the origin of which may vary. Some protein bodies arise by distention of the endoplasmic reticulum, and clearly the membrane represents the sac into which the protein is discharged after synthesis. The bounding membrane may be that of a true vacuole or it may be dictyosomal in origin.
