The present study discusses the frequency distribution and genetic diversity of novel fungal endopyte Alternaria alternata within the Pongammia pinnata plant samples. A total of ten plant samples of Pongammia pinnata, Pierre. (Karanja) were collected from specific locations of Sanganer region of Rajasthan for the isolation of fungal endophytes. Of these, maximum frequency of Alternaria alternata (22.29%) were recorded which are morphologically similar but ecologically variant. Efficacy of randomly amplified polymorphic DNA (RAPD), were assessed in seventeen individuals of the primers was GCC 180 where as 10 bands were generated by GCC 181. The similarity coefficient matrix generated for the primers was subjected to algorithm UPGMA (Unweighted Pair Group Method Analysis) and clusters were generated using NTSYS 2.02 pc program. To stabilize the level of relatedness among the seventeen ecologically variant Alternaria alternata accessions, the dendrogram was constructed, which showed that all the isolates were diversified endophytically with in the plant Pongamia pinnata. © 2013 Asian Network for Scientific Information.

Acquired immune deficiency syndrome, a disease in which there is a severe loss of the body's cellular immunity, greatly lowering the resistance to infection and malignancy. The cause is a human immune deficiency virus, or HIV transmitted in blood and in sexual fluids. AIDS was first reported June 5, 1981. A co mbination of several antiretroviral drugs, called highly active antiretroviral therapy (HAART), has been very effective in reducing the number of HIV particles in the bloodstream. The best treatment for AIDS in humans is prevention by vaccination. Source

The problem of signal reconstruction using the samples of a signal f(t) and/or signals related to f(t) has been widely investigated in the literature. However, none of the existing sampling expansions deals with the signal reconstruction in the linear canonical transform (LCT) domain using undersampled samples taken in several LCT domains. In this paper, we present some novel sampling expansions involving signal reconstruction using samples of the linear canonical transform (LCT) of the signal in some specific LCT domains. © 2012 IOP Publishing Ltd.

Investigated homogeneous magnetized cosmological model of perfect fluid distribution having disordered radiation in the presence and absence of magnetic field. To get a determinate solution, we have assumed that the universe is filled with disordered radiation and a supplementary condition is A =(BC)n between metric potentials, n is constant. It has been shown that tilted nature of the model is preserved due to magnetic field. The various physical and geometrical aspects of the model are discussed. The nature of the model in presence and absence of magnetic field is also discussed. © Electronic Journal of Theoretical Physics. Source

Plants have developed many mechanisms to protect themselves against most potential microbial pathogens and diseases. Pathogenesis-related proteins are produced as a part of the active defenses to prevent attack. In this study, the induction of PR proteins in Eruca sativa in response to fungal pathogen Alternaria brassicicola was investigated in 10 days and one-month-old plants. Induction of pathogen resulted in a much marked increase in the activities of β-1,3-glucanase and chitinase in resistant cultivar (RTM-2002) as compared to susceptible (T-27) one. The enzyme activity gradually increased throughout the experimental period of 168 h compare to control. However, the activation of β-1,3-glucanase and chitinase was more rapid and to a greater extent in plants of RTM-2002 than in T-27. western blot analysis revealed the presence of 33 and 32 kDa β-1,3-glucanase and chitinase in induced arugula plants, respectively. The biochemical approach described in this article with E. sativa provide the basis for further efforts concentrating on the isolation and characterization of elements involved in perception and in the early steps of intracellular signal transduction. © 2013 Copyright Taylor and Francis Group, LLC.
