Characteristics and Activity Changes of Proteolytic Enzymes in Apple Leaves during Autumnal Senescence.
At least four different proteinases are present in senescing apple leaves (Malus domestica Borkh. cv. Golden Delicious) as determined by their pH optima, substrate specificity, and their reactivity to proteinase inhibitors. An enzyme active at pH 4.5 to 5.0 appears to be a sulfhydryl-dependent (iodoacetamide and phenylmercuric acetate-sensitive) endoproteinase, and degradation of the large subu...
متن کاملChanges in Pigment and Element Composition of Leaves of Platanus occidentalis L. during Autumnal Leaf Senescence1
The loss of chlorophyll and total leaf nitrogen during autumnal senescence of leaves from the deciduous tree Platanus occidentalis L. was accompanied by a marked decline in the photosynthetic capacity of 02 evolution on a leaf area basis. When expressed on a chlorophyll basis, however, the capacity for lightand C02-saturated O2 evolution did not decline, but rather increased as leaf chlorophyll...

I should say from the outset that I genuinely fear that Michael Rosenzweig’s theories and examples are less broadly applicable than he argues. And yet I want to believe that he is right. If he is right, the conserv...
متن کاملThe Endowment Effect: Rose-Tinted and Dark- Tinted Glasses
The endowment effect, predicted by prospect theory, is a robust finding in behavioral decision theory. Extending recent examinations of the underlying processes, we present evidence for differential perceptions of the traded item, with sellers focusing more on positive features and less on negative features, relative to buyers. In experiment 1, sellers and buyers access information of differing...
