Some Recent Work on the Structure of the Plant Cell Wall
... one of these cations surrounded the root, all growth ceased. Signs of injury appeared in the region of elongation, i. e., where cell wall growth was most rapid. Further investigation revealed that the toxic effect was the result of changes in the cell wall itself and not the result of injury to the ...

Role of Phospholipid Head Groups in Ethanol
... Ethanol interacts with and perturbs the organization of lipid bilayers (Paterson et al., 1972; Jain & Wu, 1977); in particular it lowers the transition temperature and increases membrane fluidity (Jain & Wu, 1977). Since addition of ethanol results in a reduction in dielectric strength and thereby l ...
