Plant–plant signalling, the shade-avoidance response and competition

This is the flow of information between Plant–plant signalling Plants generate and perceive informational signals. individuals. An interaction is considered An interaction (between plants) is considered to be to be informational when it involves the informational when it involves the exchange of an exchange of an insignificant amount of matter or energy, in quantitative terms, insignificant amo...

UV-B detected by the UVR8 photoreceptor antagonizes auxin signaling and plant shade avoidance.

Plants detect different facets of their radiation environment via specific photoreceptors to modulate growth and development. UV-B is perceived by the photoreceptor UV RESISTANCE LOCUS 8 (UVR8). The molecular mechanisms linking UVR8 activation to plant growth are not fully understood, however. When grown in close proximity to neighboring vegetation, shade-intolerant plants initiate dramatic ste...

Trade-offs between the shade-avoidance response and plant resistance to herbivores? Tests with mutant Cucumis sativus

1. Plants exhibit adaptations to many stresses, including light competition and herbivory. The expression of these traits may interact negatively, potentially instigating a trade-off. 2. We employed a combination of genetically altered Cucumis sativus varieties and phenotypic manipulations to test for trade-offs in field experiments. The different genetic lines of C. sativus were altered in the...

Plant stress signalling: understanding and exploiting plant-plant interactions.

When plants are attacked by insects, volatile chemical signals can be released, not only from the damaged parts, but also systemically from other parts of the plant and this continues after cessation of feeding by the insect. These signals are perceived by olfactory sensory mechanisms in both the herbivorous insects and their parasites. Molecular structures involved can be characterized by mean...

Reproductive efficiency and shade avoidance plasticity under simulated competition

Plant strategy and life-history theories make different predictions about reproductive efficiency under competition. While strategy theory suggests under intense competition iteroparous perennial plants delay reproduction and semelparous annuals reproduce quickly, life-history theory predicts both annual and perennial plants increase resource allocation to reproduction under intense competition...
