High impact information on Tulipa

• Low temperature sensing in tulip (Tulipa gesneriana L.) is mediated through an increased response to auxin [1].
• The first, called TxLMII (second mannose-binding Tulipa hybrid lectin), is a novel mannose-binding tulip lectin [2].
• Modification of lysine, tyrosine, histidine, aspartic acid and glutamic acid residues did not affect the agglutinating activity of the Tulipa gesneriana lectin (TGL) [3].
• Microvascular protective activity of flavonoid glucuronides fraction from Tulipa gesneriana [4].
• Isolation and characterization of chitinase isoforms from the bulbs of four species of the genus Tulipa [5].

Biological context of Tulipa

• A mixture of flavonoid glucuronides, consisting of 7-O-glucuronides of kaempferol and quercetin 3-O-rutinosides, 3-O-gentiobiosides and 3-O-glucosides, was isolated from the perianths of Tulipa gesneriana L. var. 'Paradae'. It showed protective activity against the increased (both chloroform and histamine) skin vascular permeability in rabbits [4].

Associations of Tulipa with chemical compounds

• Isolation of plant cytochrome P-450 and NADPH: cytochrome P-450 reductase from tulip bulbs (Tulipa fosteriana L.) oxidizing xenobiotics [6].
• 3H uridine incorporation into nucleoli decreases markedly in both species, whereas the activity of nucleolar RNA polymerase remains at a high level in all root segments in Zea mays and decreases slightly in Tulipa kaufmanniana [7].

Gene context of Tulipa

• Cytochrome P-450 and NADPH: cytochrome P-450 reductase were solubilized by detergents from microsomal fraction of tulip bulbs Tulipa fosteriana L. and purified to electrophoretic homogeneity [6].
