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.
Journal ArticleDOI
Fruits: A Developmental Perspective.
TL;DR: It is illustrated that fruit development is a potentially useful system to learn more about complex regulatory mechanisms that control the division, growth, and differentiation of plant cells.

Source-to-sink transport of sugar and regulation by environmental factors

TL;DR: Current knowledge about the phloem transport mechanisms is summarized and the effects of several abiotic (water and salt stress, mineral deficiency, CO2, light, temperature, air, and soil pollutants) and biotic andmutualistic and pathogenic microbes, viruses, aphids, and parasitic plants are reviewed.
Journal ArticleDOI
The evolutionary ecology of tolerance to consumer damage
TL;DR: This work states that tolerance to consumer damage may be favored under a range of conditions, even when the risk and intensity of damage varies, and suggests that external constraints such as pollinator abundance or nutrient availability may also limit the evolution of tolerance.

Soluble sugars--metabolism, sensing and abiotic stress: a complex network in the life of plants.

TL;DR: Recent evidences how plants sense and respond to environmental factors through sugar-sensing mechanisms are reviewed and it is thought that forward and reverse genetic analysis in combination with expression profiling must be continued to uncover many signalling components, and a full biochemical characterization of the signalling complexes will be required to determine specificity and cross-talk in abiotic stress signalling pathways.
