Research on the mode of action of a novel 2-cyclopropyl-4-aminopyrimidine hydrazine compound (4k) for control of cyanobacteria

ABSTRACT: We reported the transcriptomics files of cyanobacteria treated by compound 4k, which exhibited a good algicidal activity. The results revealed that the transcription of genes in the photosynthesis pathways, such as thylakoid and PSI pathway, were affected by 4k, which was validated by the qPCR results. Photosynthesis parameters was further measured and showed that photosynthesis were significantly affected by 4k treatments.

Identification of photosystem I components from Chlamydomonas reinhardtii grown under oxic and anoxic conditions

Project description:Photosystem I (PSI) enables photo-electron transfer and regulates photosynthesis in the bioenergetic membranes of cyanobacteria and chloroplasts. Being a multi-subunit complex, its macromolecular organization affects the dynamics of photosynthetic membranes. Here we reveal a chloroplast PSI from the green alga Chlamydomonas reinhardtii that is organized as a homodimer.

Transcription profiling of Arabidopsis wild type and TROL (AT4G01050) knock-out plants

Project description:Here we describe TROL (thylakoid rhodanese-like protein), a nuclear-encoded component of thylakoid membranes that is required for sustaining efficient linear electron flow in vascular plants. Thus, TROL might represent a missing thylakoid membrane linker for the assembly of a ternary complex between FNR, ferredoxin and NADP+. Such a complex is necessary for maintaining photosynthetic redox poise and balancing between several alternative electron-transport pathways of oxygenic photosynthesis. TROL inactivation modulates the expression of 638 nuclear genes, revealing a novel retrograde signaling pathway. Chloroplasts are the major source of NADPH which is exported to the cytosol where it participates in various redox-dependent processes. TROL is most likely the first element in a metabolic signaling pathway which influences the expression of a large set of stress related genes. Among them are O-methyltransferases and anthocyanin 5-aromatic acyltransferase which are highly upregulated. Microarray analysis was performed in order to identify metabolic networks and pathways regulated by the deficient protein TROL. Comparing ATH1 Affymetrix data results, 317 genes were down-regulated and 321 genes were classified as up-regulated, amongst which mostly affected enzymes were catalyses, oxigenases, monooxygenases and reductases involved in the process of photosynthesis.

A binary redox control mode in gene expression and metabolism of plants

Project description:To analyze the impact of photosynthetic redox signals, light sources with spectral qualities that preferentially excite either Photosystem I (PSI light) or Photosystem II (PSII light) were used. The light sources have been described in (Fey et al., 2005). Strong reduction and oxidation signals were induced by light shifts from PSI to PSII light (PSI-II) and the reverse light shift (PSII-I), respectivly. The acclimation responses were monitored at 0.5, 2, 8, and 48h after a light shift. Samples taken prior to changing the light quality (0h) served as control. Keywords: photosynthesis, redox regulation, light acclimation, retrograde signalling, long term response Experiments were performed with plant material corresponding to pools of at least 250-500 individuals of Arabidopsis thaliana (Col-0). To abtain healthy and unstressed plants, seedlings were initially grown for 21 days under white light (short day periods, 8-h light/16-h dark) on soil. Plants were then pre-acclimated to PSI-light for 3 days and reference samples were taken. Plants were then shifted to PSII light and tissue was harvested at the described time points. Similarly, samples were harvested before and after the reverse light shift. As additional control, plants acclimated to white light were also analyzed. RNA isolation: Leaf material was harvested and frozen in liquid N2 under the respective light source. Isolation of total RNA was performed as adapted from (Westhoff et al., 1991). Array analyses using the 3292-GST nylon array were performed as described earlier (Richly et al., 2003; Fey et al., 2005). Three independent experiments with different filters and independent cDNA probes were performed (for each timepoint).
