A wide range of external stress stimuli triggers a plant cell to undergo a complex network of reactions that ultimately lead to the synthesis and accumulation of secondary metabolites. These secondary metabolites help the plant to survive under stress challenge. The potential of biotic and abiotic elicitors for the induction and enhancement of secondary metabolite production in various culture systems including hairy root (HR) cultures is well-known. The elicitor-induced defense responses involves signal perception of elicitor by a cell surface receptor followed by its transduction involving some major cellular and molecular events including activation of major secondary message signaling pathways. This result in induction of gene expressions escorting to the synthesis of various proteins mainly associated with plant defense responses and secondary metabolite synthesis and accumulation. The review discusses the elicitor-induced various cellular and molecular events and correlates them with enhanced secondary metabolite synthesis in HR systems. Further, this review also concludes that combining elicitation with in-silico approaches enhances the usefulness of this practice in better understanding and identifying the rate-limiting steps of biosynthetic pathways existing in HRs which in turn can contribute towards better productivity by utilizing metabolic engineering aspects. 相似文献

We report here measurements of the phonon density of states and the lattice dynamics calculations of strontium tungstate (SrWO4). At ambient conditions this compound crystallizes to a body-centred tetragonal unit cell (space group I41/a) called scheelite structure. We have developed transferable interatomic potentials to study the lattice dynamics of this
class of compounds. The model parameters have been fitted with respect to the experimentally available Raman and infra-red
frequencies and the equilibrium unit cell parameters. Inelastic neutron scattering measurements have been carried out in the
triple-axis spectrometer at Dhruva reactor. The measured phonon density of states is in good agreement with the theoretical
calculations, thus validating the interatomic potential developed.

Single phase solid solution forms in the Sr1-xLaSn1-xCoyO3 (x = y) system for x⩽0.05 in the samples prepared by solid state ceramic method. A few compositions were prepared in the Sr1-3x/2LaxSnO3 and SrSn1-yyCoyO3-y/2 to understand the role of La3+ and Co3+ in the electrical conduction behaviour of the system. Resistivity increases with incorppration of La3+ ions and decreases with doping of Co3+ ions. These results have been explained in terms of the defect structures of these materials. 相似文献
