Resistance and tolerance are widely viewed as two alternative adaptive responses to herbivory. However, the traits underlying resistance and tolerance remain largely unknown, as does the genetic architecture of herbivory responses and the prevalence of genetic trade-offs. To address these issues, we measured resistance and tolerance to natural apical meristem damage (AMD) by rabbits in a large ...

We used 52 Arabidopsis (Arabidopsis thaliana) accessions and developed a new set of 137 recombinant inbred lines between Landsberg erecta (Ler) and Nossen (No-0) to explore the genetic basis of phytochrome-mediated responses during deetiolation. Unexpectedly, most accessions showed weak or moderate hypocotyl growth and cotyledon unfolding responses to pulses of far-red light (FR). Crosses betwe...

doi: 10.1111/j.1399-3054.2006.00809.x Among the Arabidopsis thaliana accessions Columbia (Col), Landsberg erecta (Ler), and Wassilewskija (Ws), Ler and Ws showed higher copper (Cu) tolerance than Col, while accumulating more Cu. Thus, Cu tolerance did not appear to be related to metal exclusion. Rather, the higher Cu tolerance of Ler and Ws may reflect less Cu-induced nutrient deficiency as the...

we find the greatest values $alpha_{1} $ and $alpha_{2} $, and the least values $beta_{1} $ and $beta_{2} $ such that the inequalities $alpha_{1} c(a,b)+(1-alpha_{1} )h(a,b)
