(Submitter supplied) Ectopic expression of AtHMA4 in tomato modified Zn accumulation in a Zn-supply dependent manner. It suggests that HMA4-expression under a range of Zn-supply differentially modifies the expression of endogens, which contributes to different Zn-related phenotypes. To identify genes differentially regulated in 35S:AtHMA4-expressing and wild-type tomato, the transcription profiles were compared between roots of transgenic and WT-plants grown in the presence of 5 µM Zn. more...

(Submitter supplied) Arabidopsis HMA4 transformation facilitates Zn root-to-shoot translocation, but in Zn-supply dependent manner. It implies that distinct effects of HMA4 expression on Zn root:shoot distribution in transgenics grown under different Zn supply regimes results from the interaction between the transgene activity and the molecular background of the host plant. Microarray analysis was performed to compare expression profiles in leaves of transgenic and WT-plants grown in the presence of 5 µM Zn to identify the molecular mechanism underlying the difference in Zn root:shoot distribution between 35S:AtHMA4-expressing and wild-type tomato. more...

(Submitter supplied) Regulation of genes in shoots and roots and Arabidopsis in response to Zn-deficiency in wild-type and hma2 hma4 mutants plants We used microarrays to determine co-regulated genes in the roots of Zn deficient wild-type plants with hma2 hma4 plants from control conditions. These co-regulated genes are candidates for regulation by a systemic signal

(Submitter supplied) Iron (Fe) deficiency is a yield-limiting factor for a variety of field crops across the world and generally results from the interaction of limited soil Fe bioavailability and susceptible genotype cultivation. Tomato, a Strategy I, model plant for Fe deficiency, is an important economical crop. Tomato responses in order to improve Fe uptake are based on acidification of rhizosphere, reduction of Fe3+ to Fe2+ and transport of Fe2+ into the cells.

(Submitter supplied) To reduce the level of major second messenger inositol-1,4,5-triphosphate (InsP3), we generated transgenic tomato plants (cv. Micro-Tom) that are expressing InsP 5-ptase gene. To understand effects of transgene (InsP 5-ptase) on gene expression we carried out microarray analysis from different parts of transgenic and control (wild type, empty vector control) tomato plants Objectives for this study included the identification of genes that were up or down-regulated at the transcriptional level in transgenic tomato plants expressing InsP 5-ptase gene Keywords: genetic modification

(Submitter supplied) To investigate the effects of transgenic lines L6 and L7 tomato fruits on total expression profile of MCF-7 breast cancer cells, we treated MCF-7 cells with 1 ug/ml of tomato fruit extract for 24 hours and compare it with wild type tomato fruit extract Objectives for this study included the identification of genes that were up or down-regulated at the transcriptional level in MCF-7 cells treated with transgenic lines L6 and L7 tomatofruit extract and compare it to wild type tomato fruit extract.

(Submitter supplied) Plants adjust their growth in response to environmental cues by forming new organs in different development contexts. Underground lateral roots initiate from prepatterned cells in the main root, but cells can also bypass the root/shoot trajectory separation and generate shoot-borne-roots through an unknown mechanism. Here, we mapped tomato (Solanum lycoperiscum) shoot-borne-roots development at single-cell resolution and show that they initiate from differentiated phloem-associated cells via a unique transitional stem-cell-like state. more...

(Submitter supplied) The purpose of this dataset is to generate a transcriptomic series of staged non-induced lateral root intiation in M82 tomato. Sections of the primary roots containing lateral roots at 5 different developemental stages (staged by their anatomy and expression of the auxin response marker DR5) were collected.

(Submitter supplied) High salinity is one of the most serious threats to crop production. To 1 better understand the molecular basis of plant responses to salt stress, we combined suppression subtractive hybridization (SSH) and microarray approaches to identify the potential important or novel genes involved in salt tolerance. First, SSH libraries were constructed for two cultivated tomato (Solanum lycopersicum) genotypes: LA2711, a salt tolerant cultivar, and ZS-5, a salt sensitive cultivar, to compare salt treatment and non-treatment plants. more...

(Submitter supplied) Phosphate is a necessary macronutrient for basic biological processes, plant growth, and agriculture. Plants modulate their root system architecture and cellular processes to adapt to phosphate deprivation albeit with a growth penalty. Excess application of phosphate in the form of fertilizer can lead to eutrophication and has negative environmental impact. Moreover, phosphate mined from rock reserves is a finite and non-recyclable resource and its levels are nearing complete depletion. more...

(Submitter supplied) Wounding due to mechanical injury or insect feeding causes a wide array of damage to the cell including cell disruption, desiccation, metabolite oxidation, and disruption of primary metabolism. In response, plants regulate a variety of genes and metabolic pathways to cope with injury. Tomato (Solanum lycopersicum) is a model for wound signaling but few studies have examined the comprehensive gene expression profiles in response to injury. more...

(Submitter supplied) Tomato, a Strategy I model plant for Fe deficiency, is an important economical crop. The transcriptional responses induced by Fe deficiency in tomato roots were previously described (Zamboni et al., 2012). The changes in trascriptome caused by the supply of Fe to plants starved fro 1 week were described in relation to the different nature of chelating agents (Fe-WEHS, Fe-CITRATE and Fe-PS).

(Submitter supplied) In dicots, proplastids present in the central region of L2 layer of SAM that lack chlorophyll-binding proteins and thylakoid membranes, give rise to all green tissues of plants. These cells after a few cell divisions, reach to the periphery of the SAM, near the interface with the primordial leaves and acquire thylakoid membranes during this transition. We obtained [(i) proplastid containing, CZ, (ii) partially developed thylakoids containing, PZ and (iii) highly developed thylakoids containing, LP samples along this gradient with Laser microdissection, based on Chlorophyll fluorescence identification of cells. more...
