Chalcone synthase (CHS) catalyzes the committed enzymatic step in flavonoid biosynthesis. In parsley (Petroselinum crispum), CHS is encoded by a single gene locus. Transcriptional activation of the gene in response to UV-containing white light has been demonstrated. Analysis of the CHS gene promoter by in vivo footprinting revealed four short sequences, designated Boxes I, II, III, and IV, whic...

Treatment of parsley cell cultures with a fungal elicitor triggered the induction of a lipoxygenase isoform which may be involved in the de novo synthesis of defence-response inducers, such as jasmonic acid or 12-oxo-phytodienoic acid.

The University of Illinois’ Graduate School of Library and Information Science (uiucGSLIS) participated in TREC’s knowledge base acceleration (KBA) track in 2013. Specifically, we submitted runs for the cumulative citation recommendation (CCR) task. CCR is a type of document filtering. The use-case is that our user U is an editor of a node T in a knowledge base such as Wikipedia (for example, t...

The survival and growth of Listeria monocytogenes on fresh lettuce (Lactuca sativa), cucumber (Cucumis sativus) epidermis and parsley (Petroselinum sativum) under different relative humidity (RH) conditions and storage temperatures was studied. Inoculated vegetable pieces were stored at 10C for 7 days, 20C for 5 days, and 30C for 24 h, and at 53 and 90% RH. L. monocytogenes was enumerated perio...

Large and rapid increases in the activities of two enzymes of general phenylpropanoid metabolism, phenylalanine ammonia-lyase and 4-coumarate:CoA ligase, occurred in suspension-cultured parsley cells (Petroselinum hortense) treated with an elicitor preparation from Phytophthora megasperma var. sojae. Highest enzyme activities were obtained with an elicitor concentration similar to that required...

Parsley is a plant widely used in cooking as condiment and it has potential for pharmaceutical use due to flavonoids production, including the apiin, which antioxidant activity. The current study investigates influence of N fertilization on biomass soluble fractions, total apiin parsley plants at 28 56 days after germination (DAG). experiment was carried out greenhouse under different levels: n...

in this research the drying of four kinds of vegetables was investigated in a vacuum dryer. the effect of temperature on drying rate of samples at various temperatures (30, 35 and 45 °c) was studied. six thin-layer drying models were fitted to drying data and suitable model was selected from them. then effective moisture diffusivity and activation energy of samples were calculated. the diffusio...

A cDNA encoding flavone synthase I was amplified by RT-PCR from leaflets of Petroselinum crispum cv. Italian Giant seedlings and functionally expressed in yeast cells. The identity of the recombinant, 2-oxoglutarate-dependent enzyme was verified in assays converting (2S)-naringenin to apigenin.
