Optimal Defense (OD) theory predicts that the within-plant allocation of secondary metabolites that function as defenses will be positively correlated with the fitness value of particular plant parts. Here, we experimentally examine this prediction b

Using short (8-day) and long-term (28-day) experiments, we examined the stability of 20-hydroxyecdysone (20E) and the dominant phytosterols synthesized from a pulse of [2-14C]mevalonic acid ([14C]MVA) in hydroponically grown spinach (Spinacia olerace

The yeast C-8,7 sterol isomerase contains a polyvalent high-affinity drug binding site similar to mammalian sigma receptors. Exogenously supplied sigma ligands inhibit sterol biosynthesis in yeast, demonstrating a pharmacological relationship between

summary In Nicotiana sylvestris Spegazzini and Comes (Solanaceae), we examined the relationships among wounding, endogenous leaf jasmonic acid (JA) pools, and whole-plain (WP) nicotine accumulation over a range of wounding intensities and spatial dis

Jasmonic acid (JA) is thought to be part of a signal-transduction pathway which dramatically increases de-novo nicotine synthesis in the roots and increases whole-plant (WP) nicotine pools in response to the wounding of the leaves in Nicotiana sylves

Nicotine is thought to be an excellent example of a "mobile" (sensu Coley et al. 1985) plant defense metabolite: it is synthesized in the roots, transported to leaves, and reported to be metabolically labile, with a half-life of

Whether or not a plant can recover its investment of resources in a chemical defense is central to the “mobile-immobile” metabolite dichotomy of the resource availability theory. Biochemical measures of metabolite turnover have been used to estim

As plants become nitrogen-limited in their growth, carbon/nutrient (C/N) theory predicts a decreasing allocation of nitrogen to nitrogen-intensive defense compounds, while optimal defense (OD) theory predicts an increasing allocation to defense; C/N

Defense and regrowth after herbivore attack are not mutually exclusive alternatives for most plants, yet few studies have examined the coordination of the processes responsible for these two plant functions. To this end, we studied the coordination o

We performed field tests of alkaloid induction inNicotiana attenuata plants growing in southwestern Utah with mimicry of the two major types of damage inflicted by invertebrate and vertebrate herbivores: leaf damage and stalk removal, respectively. I
