The dilemma of plants: To grow or defend.
TL;DR: A conceptual model of the evolution of plant defense is concluded, in which plant physioligical trade-offs interact with the abiotic environment, competition and herbivory.

Grazing as an Optimization Process: Grass-Ungulate Relationships in the Serengeti
TL;DR: Experiments in Tanzania's Serengeti National Park showed that net above-ground primary productivity of grasslands was strongly regulated by grazing intensity in wet-season concentration areas of the large ungulate fauna, suggesting that conventional definitions of overgrazing may be inapplicable to these native plant-herbivore systems.
Journal ArticleDOI
Effects of Water Deficits on Carbon Assimilation
TL;DR: It is now established that the rate of C02 assimilation in the leaves is depressed at moderate water deficits, mostly as a consequence of stomatal closure, and carbon assimilation may diminish to values close to zero without any significant decline in mesophyll photosynthetic capacity.
Journal ArticleDOI
Rising Co2 Levels and Their Potential Significance for Carbon Flow in Photosynthetic Cells
TL;DR: It is concluded that control is usually shared between Rubisco (which responds sensitively to CO2) and other components (which respond less sensitively), and that photosynthesis will be stimulated by 25–75% when the CO2 concentration is doubled from 35 to 70 Pa.
Journal ArticleDOI
Sink regulation of photosynthesis
TL;DR: This work has suggested that carbohydrate accumulation in leaves when there is an imbalance between source and sink at the whole plant level can lead to decreased expression of photosynthetic genes and accelerated leaf senescence, and in a high CO2 world this may become a more prevalent feature of photosynthesis regulation.

Photosynthesis by sugar-cane leaves. A new carboxylation reaction and the pathway of sugar formation
TL;DR: Evidence is provided that the radioactivity incorporated into the C(4) dicarboxylic acid pool is transferred to sugars via 3-phosphoglycerate, which appears to be the only quantitatively significant carboxylation reaction.
Photosynthesis of crop plants as influenced by light, carbon dioxide, temperature, and stomatal diffusion resistance
TL;DR: In this article, the effect of light intensity, leaf temperature, and C0 2 concentration on photosynthetic rate in leaves of crop plants was estimated in absolute units, which allowed quantitative comparison of micrometeorological and physiological effects on photosynthesis.
