Summary
Cells of poppy (Papaver somniferum L.) which had been grownin vitro, treated with autoclavedBotrytis homogenate for 24 hours, and which had responded with browning and drastic sanguinarine accumulation, did not show lysis but presented an ultra-structure as known for parenchyma cells. The only change observed was the occurrence of electron-dense droplets in vacuoles dotting the tonoplast, stacking of the ER, and dilation of cisternae. At places where the cisternae were dilated the membranes were free of ribosomes. Sanguinarine accumulation appears not to require structural cell differentiation.
