Inter simple sequence repeat markers were employed for the genotyping of 16 plantain ecotypes. Two different electrophoretic systems namely conventional gel electrophoresis (CVGE) and fully automated high‐resolution CGE were used to evaluate the genetic diversity. Comparative analysis indicated that all parameters related to marker informativeness were higher in CGE except polymorphic information content. But genetic diversity parameters like effective number of alleles, Nei's gene diversity (1973) and Shannon's information index showed higher values (1.52 ± 0.12, 0.34 ± 0.05 and 0.52 ± 0.05, respectively) in CVGE as against CGE (1.29 ± 0.04, 0.22 ± 0.02 and 0.38 ± 0.03, respectively) system. The unweighed pair group method with arithmetic averages was used to obtain the dendrogram for both analyses. The results of dendrogram and principal component analysis were found to be consistent in both systems except for some minor disagreements. The clone‐specific bands could be used in the identification and development of SCAR markers. Inter simple sequence repeat markers used in this study provided sufficient polymorphism and reproducible banding pattern for evaluating the genetic diversity of different plantain ecotypes. Lack of accuracy and consistency of the CVGE warrants the employment of high‐throughput CGE for diversity analysis as it provided better separation of bands with higher resolution. 相似文献

A novel visible-light (blue LEDs: hν = 425 ± 15 nm) photocatalyzed one-pot method for the synthesis of electronically diverse aryl glyoxals in good to excellent yields from acetoarylones and green regents such as air, vitamin C and dioxane dibromide has been described. In addition, an application of the current methodology has been demonstrated for the oxidation of monoamine oxidase-B inhibitors, i.e., 1-(4-((4-fluorobenzyl)oxy)phenyl)ethanone and 1-(3-((4-chlorobenzyl)oxy)phenyl)ethanone. This finding may serves as a valuable alternative to the traditional acetoarylones oxidation reactions conducted using selenium dioxide a harmful and unselective reagent known to simultaneously oxidize allylic, benzylic, CH3 and so on. 相似文献

The present investigation, involving the simultaneous heat and mass transfer is concerned with a numerical study of transient natural convection flow past an impulsively started inclined plate. Crank-Nicolson implicit finite difference method is used to solve the unsteady, non-linear and coupled governing equations. In order to check the accuracy of the numerical results, the present study is compared with available exact solution and are found to be in good agreement. Numerical results are obtained for various parameters. The steady-state velocity, temperature and concentration profiles, local and average skin friction, local and average Nusselt number, local and average Sherwood number are shown graphically. It is observed that local wall shear stress decreases as an angle of inclination { decreases. 相似文献

To expedite an SAR study of the C2 position of a highly substituted benzofuran ring system, we developed a method for the preparation of a key precursor, iodide 10. From iodide 10, a diverse set of compounds with different substituents at the C2 position were prepared efficiently. 相似文献

On–off switching and molecular logic in fluorescent molecules are associated with what chemical inputs can do to the structure and dynamics of these molecules. Herein, we report the structure of a naphthalene derivative, the fashion of its binding to β-cyclodextrin and DNA, and the operation of logic possible using protons, cyclodextrin, and DNA as chemical inputs. The compound crystallizes out in a keto-amine form, with intramolecular N−H⋅⋅⋅O bonding. It shows stepwise formation of 1:1 and 1:2 inclusion complexes with β-cyclodextrin. The aminopentenone substituents are encapsulated by β-cyclodextrin, leaving out the naphthalene rings free. The binding constant of the β-cyclodextrin complex is 512 m−1. The pKa value of the guest molecule is not greatly affected by the complexation. Dual input logic operations, based on various chemical inputs, lead to the possibility of several molecular logic gates, namely NOR, XOR, NAND, and Buffer. Such chemical inputs on the naphthalene derivative are examples of how variable signal outputs based on binding can be derived, which, in turn, are dependent on the size and shape of the molecule. 相似文献

The six‐membered ring of the norbornene moiety in the title compound, C18H18N4O4, is in a slightly distorted boat conformation, and the two five‐membered rings within it adopt envelope conformations. The structure is stabilized by inter‐ and intramolecular N—H?O hydrogen bonds. 相似文献

Free convection flow of water at its maximum density past a semi-infinite inclined plate has been studied by using an implicit-finite
difference technique. The steady-state velocity and temperature profiles, local and average skin friction and the Nusselt
number are shown graphically. It is observed that velocity decreases owing to a fall in temperature of water from 20°C to
4°C. 相似文献

Mesostructured manganese oxide (Mn3O4) is prepared by a soft‐templating method employing sodium dodecyl sulfate (SDS) as a structure‐directing agent. By removing the template from the as‐prepared mesostructured Mn3O4 by extraction or calcination, we successfully synthesized highly crystallized mesoporous Mn3O4 or Mn2O3, respectively, with different crystalline structures. 相似文献
