The adaptive potential of plant endopolyploidy in response to herbivory
… are strictly negative for the plants. Overcompensation is the increase in components of fitness (flower, fruit, and/or seed yield) following herbivory. Studies by Paige and Whitham (1987) showed that when ungulate herbivores removed 95% or more of the above-ground biomass of the monocarpic …

Functional genomics of plant compensatory responses
… for tissues lost with little or no decrement in fitness relative to those that are undamaged (see Stowe et al. 2000 for a review); such plants are termed as tolerant. This trait motivated many empirical studies demonstrating that herbivore damage can, under certain circumstances, increase, rather …

Constraints on plant resistance and tolerance trade-offs
… for tissue loss with little or no detriment in fitness (tolerance) (Painter 1951). Studies have even shown that herbivory leads to, under certain environmental circumstances (Hawkes and Sullivan 2001), an increase in plant reproductive success (overcompensation, i.e., increased fruit and seed …

Overcompensation of Ipomopsis aggregata following ungulate herbivory: getting to the root of it
… now considerable evidence demonstrating enhanced fitness following herbivory, i.e., plants overcompensate. The mechanistic underpinnings of overcompensation, however, are unclear. For example, it has been assumed that plants growing in high resource conditions are best able to compensate for …

Studies into Transcriptional Pausing Regulators and Drug Resistance in Mycobacterium Tuberculosis
… (WT). This hyper-termination effect results in a fitness defect. However, there are secondary, compensatory mutations existing in the RNAP and other transcription factors that relieve hyper-termination effect and restore fitness to the cell. Using biochemical and functional, in vivo studies, we …
