Pathological anatomy of conifer needle necrosis

, : Pathological anatomy of conifer needle necrosis. Canadian Journal of Botany 51(5): 983-988

The anatomy of the disorder, caused by major environmental stresses, was investigated in several pines and Pseudotsuga menziesii to determine if histological responses could provide a diagnostic tool. All stresses studied caused a general hypertrophy of the epithelial tissue of the resin canals which became occluded. Granulation of transfusion and mesophyll parenchyma cells was also a general response.

A leucine-proline double auxotroph of Escherichia coli K-12 was starved of proline and allowed to incorporate [14C] leucine. The labeled cells were reincubated in the absence of any amino acid, in the presence of non-radioactive leucine, or in the...
