High impact information on Scrophulariaceae

• We present a phylogenetic hypothesis for parasitic Scrophulariaceae and Orobanchaceae based on sequences of the plastid gene rps2, encoding the S2 subunit of the plastid ribosome [1].
• A sucrose (Suc) transporter cDNA has been cloned from Alonsoa meridionalis, a member of the Scrophulariaceae [2].
• Low levels of genetic diversity and divergence at nuclear loci have previously been observed for cycloidea and fil1-like genes within and between several Antirrhinum species, and divergence at these loci is also low between species in genera at different levels of relatedness in the former family Scrophulariaceae (Digitalis and Verbascum) [3].
• Haustorium development was induced in vitro in roots of the parasitic Scrophulariaceae Triphysaria versicolor by treating them with exudates obtained from maize roots, the chemical 2,6-dimethoxybenzoquinone (DMBQ) or the cytokinin 6-benzylaminopurine (BAP) [4].
• Host-root exudates increase gene expression of asparagine synthetase in the roots of a hemiparasitic plant Triphysaria versicolor (Scrophulariaceae) [5].

Associations of Scrophulariaceae with chemical compounds

• Antibacterial activity of a stearic acid derivative from Stemodia foliosa [6].
• (Scrophulariaceae), exhibited an inhibitory effect on superoxide released from polymorphonuclear (PMN) cells in the nitroblue tetrazolium (NBT) assay [7].
• We previously reported that phenylpropanoids isolated from the roots of Scrophularia buergeriana Miquel (Scrophulariaceae) protected cultured cortical neurons against glutamate-induced neurotoxicity [Kim and Kim, Phytochemistry, 54 (2000) 503-509; Kim et al., Br. J. Pharmacol. 135 (2002) 1281-1291] [8].
• Three new cyclopentanoid monoterpenes, named piscrocins A , B and C, were isolated from the roots of Picrorhiza scrophulariiflora (Scrophulariaceae) [9].
• From the hexane-soluble fraction of an ethanol extract from leaves and stems of Stemodia foliosa (Scrophulariaceae), the new stearic acid 4-[(n-pentoxy)phenethyl] ester (1) was isolated [6].

Gene context of Scrophulariaceae

• The data indicate that the evolution of the plastid atpB-rbcL region was different in parasites from the Scrophulariaceae and Orobanchaceae families [10].
• Antioxidant constituents of the aerial parts of Globularia alypum growing in Morocco [11].
• Pharmacobotanical investigations on some species of the Scrophulariaceae family. Part V. Chemical constitutents in Lathraea squamaria L [12].
• (family Scrophulariaceae) (BM) is an Ayurvedic medicine, clinically used for memory enhancing, epilepsy, insomnia and as a mild sedative [13].

Analytical, diagnostic and therapeutic context of Scrophulariaceae

• De novo regeneration of Scrophularia yoshimurae Yamazaki (Scrophulariaceae) and quantitative analysis of harpagoside, an iridoid glucoside, formed in aerial and underground parts of in vitro propagated and wild plants by HPLC [14].
