cost of resistance to herbivory in the annual plant arabidopsis thaliana
this study examines the assumption that plant resistance to herbivory has fitness costs. to assess costs, i used the standard method of determining whether there is a significant negative genetic correlation between the resistance character and damage in the presence of herbivory and with fitness in the absence of herbivory. seeds of five plants from four genotypes of arabidopsis thaliana were ...
متن کاملReduced resistance to oxidative stress during reproduction as a cost of early-life stress.
Stress exposure during early-life development can have long-term consequences for a variety of biological functions including oxidative stress. The link between early-life stress and oxidative balance is beginning to be explored and previous studies have focused on this link in adult non-breeding or immature individuals. However, as oxidative stress is considered as the main physiological mecha...
متن کاملInverse relationship between systemic resistance of plants to microorganisms and to insect herbivory
Pre-inoculation of plants with a pathogen that induces necrosis leads to the development of systemic acquired resistance (SAR) to subsequent pathogen attack [1]. The phenylpropanoid-derived compound salicylic acid (SA) is necessary for the full expression of both local resistance and SAR [2] [3]. A separate signaling pathway involving jasmonic acid (JA) is involved in systemic responses to woun...

متن کاملA Physiological and Behavioral Mechanism for Leaf Herbivore-Induced Systemic Root Resistance.
Indirect plant-mediated interactions between herbivores are important drivers of community composition in terrestrial ecosystems. Among the most striking examples are the strong indirect interactions between spatially separated leaf- and root-feeding insects sharing a host plant. Although leaf feeders generally reduce the performance of root herbivores, little is known about the underlying syst...
