Role of cis-zeatin in root responses to phosphate starvation

Project description:In this work we show that root illumination influences Pi starvation responses, enhancing the root and shoot growth arrest and limiting the root/shoot ratio as well as root hair elongation. A comparative transcriptomic study using dark-grown roots (DGR) roots seedlings taht were grown with or without phosphate identifies several genes that respond to Pi deficiency that were not previously reported, likely by the negative effect of the root illumination.

Root-shoot mineral transport as a key target processes involved in Arabidopsis responsiveness to elevated [CO2] conditions

Project description:In this study we explain the physiological, biochemical and gene expression mechanisms adopted by nitrate-fed Arabidopsis thaliana plants growing under elevated [CO2], highlighting the importance of root-to-shoot interactions in these responses The transcriptomic approach (conducted at the root and shoot level) revealed that exposure to 800 ppm [CO2] conditioned the expression of genes involved in the transport of nitrate and mineral elements.

Role of cis-zeatin in root responses to phosphate starvation

Project description:In this work we show that root illumination influences Pi starvation response, enhancing the root and shoot growth arrest and limiting the root/shoot ratio as well as root hair elongation. A transcriptomic study in dark-grown roots (DGR) roots identifies several genes that respond to Pi deficiency that were not previously reported. Hormone profiling revealed that Pi starvation reduces the level of trans-Zeatin (tZ) but significantly increases the amount of cis-Zeatin (cZ) and cis-Zeatin Riboside (cZR). We have analyzed the transcriptomic response of Arabidopsis roots to phosphate starvation combined with cis- or trans-zeatin treatments for 8 hours.

Transcriptional response of A. thaliana Root and Shoot tissue to light stress and presence of microbial communities

Project description:We profiled the root and shoot transcriptomes of BFO-colonized (Bacteria, Fungi, Oomycetes) and germ free A. thaliana exposed to Low PAR (photoactive radiation, LP) and normal condition (NC) in the gnotobiotic FlowPot system five weeks post inoculation.

Auxin and ABA responsiveness in the root or the shoot of dark-grown Arabidopsis thaliana 5 day old seedlings in the aba2-3 or wild-type (Col-O) background

Project description:We report differences in the transcriptional responses of the root and the shoot to either auxin or ABA in comparison to mock treatment in dark-grown Arabidopsis thaliana seedlings. By examining the auxin responsiveness in the shoot or the root of a dark-growh ABA biosynthesis mutant, we found that auxin relies on intact ABA biosynthesis in order to regulate aspects of transriptional output.

Shoot-to-root mobile CEPD-like 2 integrates shoot nitrogen status to systemically regulate nitrate uptake in Arabidopsis

Project description:Plants modulate the efficiency of root nitrogen (N) acquisition in response to shoot N demand. However, molecular components directly involved in this shoot-to-root communication remain to be identified. Here, we show that phloem-mobile CEPD-like 2 (CEPDL2) polypeptide is upregulated in the leaf vasculature in response to decreased shoot N status and, after translocation to the roots, promotes high-affinity uptake and root-to-shoot transport of nitrate by activating nitrate transporter genes such as NRT2.1, NRT3.1 and NRT1.5. Loss of CEPDL2 decreases nitrate uptake and root-to-shoot transport activity in roots, leading to a reduction in shoot nitrate content and plant biomass. CEPDL2 contributes to N acquisition cooperatively with CEPD1 and CEPD2 that mediate root N status, and their complete loss severely impairs N homeostasis in plants. Reciprocal grafting analysis provided conclusive evidence that the shoot CEPDL2/CEPD genotype defines the root high-affinity uptake activity of nitrate. Our results indicate that plants integrate shoot N status and root N status in leaves and systemically regulate the efficiency of root N acquisition.
