Stevia rebaudiana: Its agricultural, biological, and chemical properties
The purpose of this review is to summarize the existing agricultural, chemical and biochemical literature to provide a baseline for new research on stevia sweeteners.
Rebaudioside F, a diterpene glycoside from Stevia rebaudiana.

The results show that CPS and KS are part of the steviol glycoside biosynthetic pathway and that Stevia rebaudiana has recruited two genes to secondary metabolism from a highly regulated pathway involved in hormone biosynthesis.

For several millennia, stem extracts of Ephedra have been used as folk medicines in both the Old and New World, and together with Asian species they contain other nitrogen-containing secondary metabolites with known neuropharmacological activity.
Rapid mineralization of the endocrine‐disrupting chemical 4‐nonylphenol in soil
The persistence of the xenoestrogenic compound 4‐nonylphenol in agricultural, noncultivated temperate, and Arctic soils was assessed in laboratory microcosm incubations. At 30°C,…
Structure of the pentapeptide proctolin, a proposed neurotransmitter in insects.
Identification of a chromosomal region required for biosynthesis of the phytotoxin coronatine by Pseudomonas syringae pv. tomato
Because pEC18 did not complement all five mutants or confer the ability to produce toxin on nonproducing P. syringae pathovars, sequences outside this cloned region must also be involved in toxin synthesis.
Identification of Tomato Leaf Factors that Activate Toxin Gene Expression in Pseudomonas syringae pv. tomato DC3000.
ABSTRACT Coronatine is a non-host-specific chlorosis-inducing phytotoxin produced by the tomato and crucifer pathogen Pseudomonas syringae pv. tomato DC3000. How the chromosomal gene cluster…
The Effect of Tricyclazole and Culture Medium on Production of the Melanin Precursor 1,8-Dihydroxynaphthalene by Sclerotinia sclerotiorum Isolate SS7
The results indicate that tricyclazole does inhibit the biosynthesis of polyketides in isolate SS7 of S. sclerotiorum but melanin pathways other than that which produces DHN may also be operational in this fungus.
In vitro methylation of DNA by the fumigant methyl bromide.
1-Methyl-adenine and 7-methylguanine were identified, after hydrolysis, as the major methylated bases of DNA which had been treated in the solid state and the overall methylation pattern was similar to that observed earlier for DNA of maize and wheat which has been fumigated.
