Project description:Glutaredoxins (GRXs) are the ubiquitous oxidoreductase enzymes, which play important role in defense against various stresses. To analyze the function of a CC-type rice GRX gene, OsGRX8, we overexpressed it into Arabidopsis constitutively. The physiological analyses revealed that overexpression of GRX gene enhanced abiotic stress tolerance in transgenic plants as compared to wild-type. We used microarrays to study the global effect of overexpression of OsGRX8 in Arabidopsis under control and various treatments. Wild-type and transgenic Arabidopsis seedlings were grown on MS medium for 14-days in a culture room with a daily photoperiodic cycle of 16h light and 8h dark. Seedlings were incubated in water (control) or 100 µM solution of indole-3-acetic acid (auxin, IAA), 200 mM sodium chloride (salt, NaCl) and 25 µM solution of methyl viologen (MV)for 3h. The 500 ng of total RNA sample isolated from each tissue sample was processed for microarray analysis according to Affymetrix protocol. Two biological replicates for each sample (control, IAA, NaCl and MV) of wild-type and GRX overexpression line were used for microarray analysis.

Project description:MeGRX232 and MeGRX360 are drought-inducible CC-type glutaredoxins in cassava. Overexpression of them in Arabidopsis caused different effects on plant growth. We used microarray to identified the different expression genes in MeGRX232-OE and MeGRX360-OE Arabidopsis

Project description:Homeobox transcription factors are known to regulate plant growth and development. Recently, they have also been implicated in abiotic stress responses. To analyze the role of HD-ZIP I subfamily member, OsHOX24, we constitutively overexpressed it in Arabidopsis. The physiological analyses revealed that overexpression of OsHOX24 gene severely reduced abiotic stress tolerance in transgenic plants as compared to wild-type. We used microarrays to study the global effect of OsHOX24 overexpression in Arabidopsis under control condition.

Project description:Pathak2013 - MAPK activation in response to various abiotic stresses

Abstract:
Mitogen-Activated Protein Kinases (MAPKs) cascade plays an important role in regulating plant growth and development, generating cellular responses to the extracellular stimuli. MAPKs cascade mainly consist of three sub-families i.e. mitogen-activated protein kinase kinase kinase (MAPKKK), mitogen-activated protein kinase kinase (MAPKK) and mitogen activated protein kinase (MAPK), several cascades of which are activated by various abiotic and biotic stresses. In this work we have modeled the holistic molecular mechanisms essential to MAPKs activation in response to several abiotic and biotic stresses through a system biology approach and performed its simulation studies. As extent of abiotic and biotic stresses goes on increasing, the process of cell division, cell growth and cell differentiation slow down in time dependent manner. The models developed depict the combinatorial and multicomponent signaling triggered in response to several abiotic and biotic factors. These models can be used to predict behavior of cells in event of various stresses depending on their time and exposure through activation of complex signaling cascades.

Project description:Hormones effect various plant developmental processes by altering gene expression. The expression of several genes is regulated by plant hormones and many of these genes are regulated commonly and specifically by various hormones. We used microarrays to study the global effect of plant hormones on rice gene expression and identify the genes involved in operlapping and specific transcriptional responses.

Project description:An increasing number of studies have demonstrated that miRNAs may act as oncogenes or anti-oncogenes in various types of cancer, including colon carcinoma (CC). However the clinical and biological significance of miR663a in the prognosis of CC and its underlying mechanisms remain unknown. In our study, it was found that miR663a was significantly downregulated in CC, especially in metastatic CC tissues. MiR663a overexpression not only inhibited the proliferation and migration/invasion of CC cells in vitro, but also inhibited tumor growth and metastasis of CC cells in vivo. However the mechanism under that was still unknown. So miR663a target genes were analyzed in our project.

Project description:We used Bio-Rad laboratories, lnc. PCR assay panel to analyze expression levels of MAPK genes under various stress conditions and plant hormone treatments. Cucumber plants of the ‘Jinyan No.4’ cultivar were reared in growth chambers at 28 ± 1 °C with a photoperiod of 16 h light/8 h dark and light intensity of 400 μmol m−2 s−1. Three-week-old seedlings were used for all abiotic and biotic treatments. For heat or cold treatment, the seedlings were subjected to 35 ± 1 °C or 4 ± 1 °C conditions, respectively. The samples for RNA extraction were collected at 0, 1, 2, 4, and 8 h after treatment. For dehydration treatment, the leaves of plants were sampled at 0, 2, 4, and 6 d after watering stopped. For disease treatment, Pseudoperonospora cubensis (P.cubensis) was used to infect the seedlings, and leaves were collected at 0, 1, 2, and 3 d after infection. For hormone treatments, the seedling leaves were sprayed with 100 mM methyl jasmonate (meJA) or 100 mM abscisic acid (ABA) and then sampled at 0, 1, 2, 4, and 8 h intervals. The experiment was designed to examine the transcription patterns of 58 MAPK cascade genes in cucumber in response to three different abiotic stresses (cold, heat, and drought), one biotic stress (Pseudoperonospora cubensis) and two (MeJA and ABA) plant hormone treatments.
