Not AvailableHeat stress leads to an array of physiological, biochemical, and molecular changes in plants affecting its growth and development. An experiment was conducted to find out the effect of short-term heat stress on osmo-protectant and antioxidants in 37 genotypes (32 mutants and five varieties) of moth bean (Vigna aconitifolia). Seeds were grown in plastic pots containing sterilized vermiculite. Heat stress conditions were created by exposing seven days old seedlings at 42 °C for one hour in hot air oven. Analysis of various parameters was carried out at three days after heat stress. A significant over-accumulation of total sugar and proline along with an increased activity of CAT, GPOX and SOD was observed in most of the genotypes under heat stress. However, correlation analysis among heat stress induced biochemical parameters suggests that none of these traits were associated with the level of thermo-tolerance except GPOX activity. Among 37 genotypes, on the basis of number of fresh plants with least wilting symptoms, six were categorized as tolerant, 13 as moderately tolerant and 18 as susceptible accession. Eventually, it is evident that thermo tolerance and biochemical parameters can be efficiently altered and improved through mutagenesis, though this altered tolerance level could not be associated with the parameters studied in the present investigation.Not Availabl

Not AvailableMoth bean (Vigna aconitifolia (Jacq.) Marechal) is an important grain legume crop grown in rain fed areas of hot desert regions of Thar, India, under scorching sun rays with very little supplementation of water. An SSH cDNA library was generated from leaf tissues of V. aconitifolia var. RMO-40 exposed to an elevated temperature of 42 °C for 5 min to identify early-induced genes. A total of 488 unigenes (114 contigs and 374 singletons) were derived by cluster assembly and sequence alignment of 738 ESTs; out of 206 ESTs (28%) of unknown proteins, 160 ESTs (14%) were found to be novel to moth bean. Only 578 ESTs (78%) showed significant BLASTX similarity (<1 × 10–6) in the NCBI non-redundant database. Gene ontology functional classification terms were retrieved for 479 (65%) sequences, and 339 sequences were annotated with 165 EC codes and mapped to 68 different KEGG pathways. Four hundred and fifty-two ESTs were further annotated with InterProScan (IPS), and no IPS was assigned to 153 ESTs. In addition, the expression level of 27 ESTs in response to heat stress was evaluated through semiquantitative RT–PCR assay. Approximately 20 different signaling genes and 16 different transcription factors have been shown to be associated with heat stress in moth bean for the first time.Not Availabl

BAFF- and APRIL-Dependent Maintenance of Antibody Titers after Immunization with T-Dependent Antigen and CD1d-Binding Ligand

CD1d-restricted invariant Natural Killer T (iNKT) cells boost humoral immunity to T-dependent Ags that are co-administered with the CD1d-binding glycolipid Ag α-galactosylceramide (α-GC). Observations that mice lacking iNKT cells have decaying Ab responses following vaccination has led to the hypothesis that iNKT cells express plasma cell (PC) survival factors that sustain specific Ab titers. Bone marrow (BM) chimeric mice in which the entire hematopoetic compartment or iNKT cells selectively lacked BAFF, APRIL, or both BAFF and APRIL were created and immunized with NP-KLH adsorbed to Alum or mixed with α-GC. In comparison to BAFF- or APRIL-sufficient BM chimeras, absence of hematopoetic compartment- and iNKT-derived BAFF and APRIL was associated with rapidly decaying Ab titers and reduced PC numbers. The iNKT cell-derived BAFF or APRIL assumed a greater role in PC survival when α-GC was used as the adjuvant for immunization. These results show that iNKT-derived BAFF and APRIL each contribute to survival of PCs induced by immunization. This study sheds new light on the mechanisms through which iNKT cells impact humoral immunity and may inform design of vaccines that incorporate glycolipid adjuvants

Consumo y cultura masiva: reflexiones a propósito de la literatura de autoayuda y sus lectores

Teniendo en cuenta que la cultura es comprensible a partir del estudio de sus componentes simbólicos, en nuestra tesis de doctorado indagamos en una práctica cultural cuyo interés se renueva incesantemente resistiendo a los avatares del tiempo: la lectura. Acotamos el estudio a un género de la cultura de masas que ostenta una imponente presencia en el mercado editorial actual: la literatura de autoayuda. Asimismo, con la intención de dar una realidad sociocultural a la figura del lector, abordamos un caso en particular: San Salvador de Jujuy (Argentina). A partir de ello, en este artículo, reflexionamos específicamente a propósito de las expectativas de lectura y nos preguntamos: ¿qué se busca en la literatura? Sobre la base de nuestra investigación, concluimos en que el consumo de los libros de autoayuda puede vincularse, por un lado, a la necesidad de dar orden y sentido a la historia personal y, por otro, a la búsqueda de sentimientos etéreos, la libertad y la felicidadDado que a cultura é entendida através do estudo de seus componentes simbólicos, em nossa tese de doutorado, investigamos uma prática cultural que renova incessantemente interesse y resiste às vicissitudes do tempo: a leitura. Limitamos o estudo a um gênero da cultura de massa que detém uma presença dominante no mercado editorial atual: a literatura de auto-ajuda. Além disso, com a intenção de dar uma realidade sociocultural à figura do leitor, nós abordamos um caso particular: San Salvador de Jujuy (Argentina). A partir disso, neste artigo, refletimos especificamente sobre as expectativas de leitura e questionamos: o que se busca na literatura? Com base em nossa pesquisa, concluímos que o consumo de livros de autoajuda pode ser ligado, por um lado, com a necessidade de dar forma e sentido à história pessoal e, por outro, com a busca de sentimentos etéreos, a liberdade e felicidade.Given that culture is understandable from the study of symbolic components, in our doctoral thesis (Canavire, 2013) we investigate a cultural practice whose interest is renewed constantly resisting the vicissitudes of time: reading. We delimit the study to a genre of massive culture that boasts an imposing presence in the current publishing market: self-help literature. Also, with the intention of giving a sociocultural reality to the figure of the reader, we tackle a particular case: San Salvador de Jujuy (Argentina). From this, in this article, specifically we reflect with regard to expectations about reading and we ask what is searched in the literature? Based on our research, we conclude that the consumption of self-help books can be linked, on the one hand, with the need to give order and meaning to the personal history and, on the other, to looking ethereal feelings, freedom and happiness.Fil: Canavire, Vanina Belén.

Mutations in cohesin complex members SMC3 and SMC1A cause a mild variant of Cornelia de Lange syndrome with predominant mental retardation

Mutations in the cohesin regulators NIPBL and ESCO2 are causative of the Cornelia de Lange syndrome (CdLS) and Roberts or SC phocomelia syndrome, respectively. Recently, mutations in the cohesin complex structural component SMC1A have been identified in two probands with features of CdLS. Here, we report the identification of a mutation in the gene encoding the complementary subunit of the cohesin heterodimer, SMC3, and 14 additional SMC1A mutations. All mutations are predicted to retain an open reading frame, and no truncating mutations were identified. Structural analysis of the mutant SMC3 and SMC1A proteins indicate that all are likely to produce functional cohesin complexes, but we posit that they may alter their chromosome binding dynamics. Our data indicate that SMC3 and SMC1A mutations (1) contribute to ∼5% of cases of CdLS, (2) result in a consistently mild phenotype with absence of major structural anomalies typically associated with CdLS, and (3) in some instances, result in a phenotype that approaches that of apparently nonsyndromic mental retardation
