cyclopropane/arabidopsis thaliana

Cyclopropane fatty acids (CPAs) are desirable as renewable chemical feedstocks for the production of paints, plastics, and lubricants. Toward our goal of creating a CPA-accumulating crop, we expressed nine higher plant cyclopropane synthase (CPS) enzymes in the seeds of fad2fae1 Arabidopsis

The ethylene forming enzyme (EFE) is a key factor in ethylene biosynthesis. To understand better the regulation of ethylene biosynthesis in vegetative tissues, we set out to isolate and characterize a complementary DNA (cDNA) encoding the EFE from Arabidopsis thaliana. An A. thaliana cDNA library

Plant roots show growth cessation as a primary response to mechanical stress. To clarify the molecular basis of this response, we have previously established an assay system to monitor the root growth response of Arabidopsis seedlings to mechanical stimuli using dialysis membrane-covered agar media.

S-Adenosyl-l-methionine:tetrahydroprotoberberine cis-N-methyltransferase (EC 2.1.1.122) catalyzes the conversion of (S)-stylopine to the quaternary ammonium alkaloid, (S)-cis-N-methylstylopine, as a key step in the biosynthesis of protopine and benzophenanthridine alkaloids in plants. A full-length

A study of plant defensive systemic responses induced by three plant growth promoting rhizobacteria (PGPR) on Arabidopsis thaliana Col 0 against Pseudomonas syringae pv. tomato DC3000 at the biochemical and transcriptional levels is reported in this paper. All three strains decreased disease

The enzyme CPI (cyclopropylsterol-cycloisomerase) from the plant sterol pathway catalyses the cleavage of the 9β,19-cyclopropane ring of the 4α-methyl-cyclopropylsterol cycloeucalenol to produce the Δ8-sterol obtusifoliol. Randomly mutated plasmids carrying the Arabidopsis thaliana cpi gene were

We carried out transcriptional profiling analysis in 10-d-old Arabidopsis thaliana seedlings treated with oligogalacturonides (OGs), oligosaccharides derived from the plant cell wall, or the bacterial flagellin peptide Flg22, general elicitors of the basal defense response in plants. Although

The flowers of most dicotyledons have petals that, together with the sepals, initially protect the reproductive organs. Later during development petals are required to open the flower and to attract pollinators. This diverse set of functions demands tight temporal and spatial regulation of petal
