Homologues of the flavonoid 3 ,5 -hydroxylase (F3 5 H) gene, a key gene determining flower color, were obtained from a Verbena hybrida (verbena) cultivar Temari Violet, verbena cultivar Tapien Pink, and Clitoria ternatea (butterfly pea). The expression of the Temari and butterfly pea homologues in yeast confirmed that they encoded F3 5 H. The two genes under the control of an enhanced cauliflow...
متن کامل3,4-Diaminopyridinium 2-carboxy-4,6-dinitrophenolate
In the title salt, C(5)H(8)N(3) (+)·C(7)H(3)N(2)O(7) (-), the pyridine N atom of the 3,4-diamino-pyridine mol-ecule is protonated. The 3,5-dinitro-salicylate anion shows whole-mol-ecule disorder over two orientations with a refined occupancy ratio of 0.875 (4): 0.125 (4). In the crystal, the cations and anions are connected by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dime...
متن کاملDecoding the Ternary (23, 11, 9) Quadratic Residue Code
Quadratic residue (QR) codes are cyclic, nominally half-rate codes, that are powerful with respect to their error-correction capabilities. Decoding QR codes is in general a difficult task, but great progress has been made in the binary case since the work of Elia [1] and He et al. [2]. Decoding algorithms for certain nonbinary QR codes were proposed by Higgs and Humphreys in [3] and [4]. In [5]...
متن کاملKinetic study on the electrodecolorization of C.I. Acid Yellow 23
The electrocoagulation (EC) is a simple and efficient method for the treatment of many water and wastewaters.The kinetics of decolorization of Acid Yellow 23 by EC using iron electrodes was studied. Theelectrodecolorization rate follows pseudo-first order kinetic with respect to the AY23 concentration havingkapp= 5.65 cm min-1 at T= 295 K. The rate equation is as follows:ln [AY23]t – ln [AY23]0...
متن کامل3-Cyano-11-oxo-3,4-seco-12a-aza-C-homoolean-4(23)-en-28-oic acid methyl ester
The title compound, C(31)H(48)N(2)O(3), is a Beckmann rearrangement product. The isopropenyl and meth-oxy-carbonyl groups have β-orientations, whereas the 2-cyano-ethyl group has an α-orientation. In the triterpenoid skeleton, the seven-membered lactam ring, as well as the three six-membered carbocyclic rings, have chair conformations. In the crystal, mol-ecules are linked via nonclassical C-H⋯...
