High impact information on Petroselinum

• In Petroselinum crispum, pathogen defense has been shown to be associated with extensive metabolic reprogramming, including strong repression of the UV-protective flavonoid biosynthetic pathway [1].
• Results from this study show that the mRNAs encoding representative enzymes from various supply pathways are coinduced in UV-irradiated parsley cells (Petroselinum crispum) with two mRNAs of flavonoid glycoside biosynthesis, encoding phenylalanine ammonia-lyase and chalcone synthase [2].
• Rapid, transient, and highly localized induction of plastidial omega-3 fatty acid desaturase mRNA at fungal infection sites in Petroselinum crispum [3].
• Two NADPH:cytochrome P450 oxidoreductases (CPRs) from parsley (Petroselinum crispum) were cloned, and the complete proteins were expressed and functionally identified in yeast [4].
• Induction of 3-deoxy-D-arabino-heptulosonate-7-phosphate synthase activity by fungal elicitor in cultures of Petroselinum crispum [5].

Biological context of Petroselinum

• Substrate specificity of chalcone synthase from Petroselinum hortense. Formation of phloroglucinol derivatives from aliphatic substrates [6].
• Serine-202 is the putative precursor of the active site dehydroalanine of phenylalanine ammonia lyase. Site-directed mutagenesis studies on the enzyme from parsley (Petroselinum crispum L.) [7].
• Effect of parsley (Petroselinum crispum) intake on urinary apigenin excretion, blood antioxidant enzymes and biomarkers for oxidative stress in human subjects [8].
• Two higher plant systems are presented which allow to study coordinated gene expression of the light-induced metabolic pathway of flavonoid biosynthesis: tissue culture cells of Petroselinum hortense (Apiaceae) and different developmental stages of various genotypes of Matthiola incana (Brassicaceae) [9].

Anatomical context of Petroselinum

• The fractionation of cells of a parsley suspension culture [Petroselinum crispum (Mill.) A. Hill] by protoplasting and subsequent removal of the vacuoles led to physiologically intact evacuolated protoplasts retaining light inducibility of chalcone synthase expression [10].
• Light-induced enzyme synthesis in cell suspension cultures of Petroselinum hortense. Demonstration in a heterologous cell-free system of rapid changes in the rate of phenylalanine ammonia-lyase synthesis [11].
• Improved purification and further characterization of acetyl-CoA carboxylase from cultured cells of parsley (Petroselinum hortense) [12].
• Effects of Petroselinum crispum extract on pancreatic B cells and blood glucose of streptozotocin-induced diabetic rats [13].

Associations of Petroselinum with chemical compounds

• The genetic fine structure of cis-acting sequences previously shown to be necessary for light-regulated expression in the promoter of the parsley (Petroselinum crispum) chalcone synthase gene was analyzed [14].
• A purified enzyme preparation from cell suspension cultures of parsley (Petroselinum hortense) catalyzed chain elongations with acetate units from malonyl-CoA, using various aromatic and aliphatic CoA esters as starter molecules [6].
• A group of recently isolated parsley (Petroselinum crispum) cDNAs representing genes that are transcriptionally activated upon fungal infection or elicitor treatment have been demonstrated to encode tyrosine decarboxylase (TyrDC) [15].
• Large changes in the rate of synthesis of UDP-apiose synthase, an enzyme of the flavonoid glycoside pathway, were observed both in vivo and in vitro following irradiation of previously dark-grown cell suspension cultures of parsley (Petroselinum hortense) [16].
• Neutral complexes as oxidants for the reduced form of parsley (Petroselinum crispum) [2Fe--2S] ferredoxin. Evidence for partial blocking by redox-inactive Cr(III) complexes [17].

Gene context of Petroselinum

• We have cloned an Arabidopsis thaliana chalcone synthase (CHS) gene on the basis of cross-hybridization with a Petroselinum hortense CHS cDNA clone [18].
• The Smh-type genes are plant specific and include a gene family in Arabidopsis and the PcMYB1 gene of parsley (Petroselinum crispum) but are distinct from those (AtTRP1, AtTBP1, and OsRTBP1) recently shown to encode in vitro telomere-repeat DNA-binding activity [19].
• Purification and characterization of chromatin-bound DNA-dependent RNA polymerase I from parsley (Petroselinum crispum). Influence of nucleoside triphosphates [20].
• Glutathione S-transferase (GST) assay-guided fractionation of parsley leaf oil from the edible plant Petroselinum sativum Hoffm [21].
• Acetyl-CoA carboxylase from irradiated cell-suspension cultures of parsley (Petroselinum hortense) has been purified to apparent homogeneity [12].

Analytical, diagnostic and therapeutic context of Petroselinum

• The purification of DNA-dependent RNA polymerase II (EC 2.7.7.6) from plant cell cultures of Petroselinum (parsley) is described [22].
