Respiratory Q10 of Lettuce Increases with Increasing Plant Size

Plant genotypic diversity increases population size of a herbivorous insect.

It is critical to incorporate the process of population dynamics into community genetics studies to identify the mechanisms of the linkage between host plant genetics and associated communities. We studied the effects of plant genotypic diversity of tall goldenrod Solidago altissima on the population dynamics of the aphid Uroleucon nigrotuberculatum. We found genotypic variation in plant resist...

Coenzyme Q10 increases cholesterol efflux and inhibits atherosclerosis through microRNAs.

Arbovirus infection increases with group size.

Buggy Creek (BCR) virus is an arthropod-borne alphavirus that is naturally transmitted to its vertebrate host the cliff swallow (Petrochelidon pyrrhonota) by an invertebrate vector, namely the cimicid swallow bug (Oeciacus vicarius). We examined how the prevalence of the virus varied with the group size of both its vector and host. The study was conducted in southwestern Nebraska where cliff sw...

Physiological and biochemical responses of lettuce plant to the allochemical compound of paraxanthine

IIn this study, the effects of paraxanthin on lettuce were investigated. Paraxanthin is a group of purine alkaloids, secondary metabolites of plants. This compound is made up of the caffeine metabolism found in plants such as tea, coffee and cocoa. There have been previous reports of paraxanthine antihypertensive properties.Three different concentrations of paraxanthine as 10, 50 and 100 µg/ml ...

Phylogenetic isolation increases plant success despite increasing susceptibility to generalist herbivores

Exotic species are invading new ecosystems faster than has ever occurred via natural processes (Mack et al., 2000), homogenizing the world’s biota and leading to significant ecological and economic impacts (Wilcove et al., 1998; Pimentel et al., 2005). It has long been hypothesized that invasions are biased towards introduced species that are unrelated to the recipient community. Darwin’s Natur...
