Gene expression profiles in growth-inhibition rice seedling implanted by the low-energy N+ beam

ABSTRACT: Knowledge of genes expression related to the growth-inhibition biological effects induced by low-energy N+ in plant. This study investigated the differentially expressed genes (DEGs) related to the growth-inhibition biological effects induced by low-energy N+ in plant by RNA-seq. Ion fluences (40Kev, curren intensity=3mA) of 1×1017N+/cm2，2×1017N+/cm2，4×1017N+/cm2，6×1017N+/cm2，8×1017N+/cm2 were used in the ion-implanted experiments. Biological effects with growht-inhibition were arised from the samples implanted by the ion fluences of 6×1017N+/cm2，8×1017N+/cm2 because of the inhibition of seedling height and root length. We sequenced mRNA from these damaged rice seedlings and others. We identified 776 transcripts as reliable DEGs at the growth inhibition sample campared with the control.The pathway enrichment analysis of these 776 DEGs showed that pathway of photosynthesis - antenna proteins was down-regulated. Meanwhile transcription factor analysis showed that genes related to AUX/IAA were also down-regulated. This study were contributed to a better understanding of molecular events responsible for adaption to the implantation of low-energy ion beam in plant.

Nitrogen-ion-beam implantation effect on rice dry seeds

Project description:Analysis of 96-hours-old-rice seedlings with promoted-growth induced by implantation with low-energy nitrogen ion beam. Ion-beam implantation can induce changes in 351 up-regulated transcripts and 470 down-regulated transcripts, including signaling proteins, kinases, plant hormones, transposable elements, transcription factors, non-coding protein RNAs, secondary metabolites, resistance proteins, peroxidase, chromatin modification and even miRNAs. Results provide insight into the molecular basis of biological effects of plants that implanted by ion beam. Three sample groups—the controls, the ion-beam implanted samples and vacuum-treated samples. Three replicates were included in each sample group. Radiation induced gene expression rice seedlings was measured at 96 hours after germination of the seeds.

RNA-Seq of WT and -P treatment

Project description:To further explore the molecular mechanisms of P regulation in banana plants, we used RNA sequencing-based transcriptomic analysis for banana plants subjected to Pi deficit stress for 60 days.We detected 1900 significantly differentially expressed genes (DEGs) in aboveground plant parts and 7398 DEGs in root parts under low P stress. Gene ontology (GO) classification analysis showed that 156,291 GO terms belonging to molecular functions, 53,114 GO terms belonging to cellular components, and 228,544 GO terms belonging to biological processes were enriched in the aboveground and root components. A number of DEGs involved in energy metabolism-related processes, signal transduction, control of rhizosphere P activation, and Pi mobilization were found, which were confirmed by quantitative reverse-transcription PCR (RT-PCR) analysis. At the transcriptomic level, we detected 13 DEGs from different organs and with different functions in the time-course response to phosphorus deficiency stress. These DEGs may include some key genes that regulate the phosphorus network, increasing our understanding of the molecular mechanism of Pi homeostasis in banana.

The effects of low-level Er:YAG laser irradiation on proliferation and calcification of primary osteoblast-like cells isolated from rat calvaria

Project description:A number of reports showed that photo-bio-modulation by various lasers has favorable biological effects on cells. However, the effects of low-level Er:YAG laser irradiation on osteoblasts remain unclear. The purpose of this study was to evaluate the effects on proliferation and osteogenic differentiation of primary osteoblast-like cells by low-level Er:YAG laser irradiation. Osteoblast-like cells isolated from the calvariae of 3–5-day-old Wistar rats were irradiated by Er:YAG laser at energy fluences of 2.2, 3.3, or 4.3 J/cm2, respectively. After irradiation, cell surface temperature was measured and cell proliferation was evaluated by flow cytometry. Calcification was evaluated by measuring the Alizarin red S staining area after 7-day-culture with osteoinductive medium. Gene expressions in non-irradiated and laser-irradiated cells were evaluated by qPCR at 3, 6, and 12 hours after irradiation. Microarray analysis was performed to comprehensively evaluate gene expressions of non-irradiated cells and irradiated cells at 3.3 J/cm2 at 6 hours after irradiation. No pronounced increase of cell surface temperature was induced by low-level Er:YAG laser irradiation, and the Er:YAG laser irradiation did not affect osteoblast-like cell proliferation. Osteoblast-like cell calcification was significantly increased 7 days after Er:YAG laser irradiation at 3.3 J/cm2. Bglap expression was significantly increased in cells irradiated at 3.3 J/cm2 at 6 hours post-irradiation. Microarray analysis showed that irradiation at 3.3 J/cm2 caused up-regulation of inflammation-related genes and down-regulation of Wisp2. Gene set enrichment analysis also clarified enrichment of inflammation-related gene sets and Notch signaling pathway. In conclusion, Low-level Er:YAG laser irradiation enhanced calcification of primary osteoblast-like cells via enhanced Bglap expression and enriched Notch signaling pathway.

The effects of primary cilia on endothelial gene expression exposed to flow

Project description:Biomechanical forces such as wall shear stress induced by flowing blood influence the behavior of vascular cells and have been shown to be crucial in the onset of vascular disease. Primary cilia are increasingly recognized as important biological sensors of low WSS. The goal of the study was to investigate gene expression profile of endothelial cell under low flow (2 dynes/cm2) as compared to physiological flow (30 dynes/cm2) in presence or absence of primary cilia.

Sweet corn: low- vs. high-yielding hybrids

Project description:Transcriptional profiling of sweet corn plant density (crowding stress) tolerance influencing yield. Tolerance to crowding stress has played a crucial role in improving agronomic productivity in field corn; however, commercial sweet corn hybrids vary greatly in crowding stress tolerance. The experiment was conducted to 1) explore transcriptional changes among sweet corn hybrids with differential yield under crowding stress, 2) identify relationships between phenotypic responses and gene expression patterns, and 3) identify groups of genes associated with yield and crowding stress tolerance. Under conditions of crowding stress, three high-yielding and three low-yielding sweet corn hybrids were grouped for transcriptional and phenotypic analyses. Transcriptional analyses identified from 372 to 859 common differentially expressed genes (DEGs) for each hybrid. Large gene expression pattern variation among hybrids and only 26 common DEGs across all hybrid comparisons were identified, suggesting each hybrid has a unique response to crowding stress. Over-represented biological functions of DEGs also differed among hybrids. Strong correlation was observed between: 1) modules with up-regulation in high-yielding hybrids and yield traits, and 2) modules with up-regulation in low-yielding hybrids and plant/ear traits. Modules linked with yield traits may be important crowding stress response mechanisms influencing crop yield. Functional analysis of the modules and common DEGs identified candidate crowding stress tolerant processes in photosynthesis, glycolysis, cell wall, carbohydrate/nitrogen metabolic process, chromatin, and transcription regulation. Moreover, these biological functions were greatly inter-connected, indicating the importance of improving the mechanisms as a network. 3 high-and 3 low-yielding hybrids with 2-3 biological replications grown under high population density (crowding stress)
