(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) Transgenic Arabidopsis plants with constitutively low inositol (1,4,5) triphosphate exhibit an increased tolerance to water stress by an ABA-independent pathway The phosphoinositide pathway and inositol (1,4,5) trisphopsphate (InsP3) are implicated in plant responses to stress. In order to manipulate the pathway and determine the downstream consequences of altered InsP3-mediated signaling, we generated transgenic Arabidopsis plants expressing the mammalian type I inositol polyphosphate 5-phosphatase, an enzyme that specifically hydrolyzes the soluble inositol phosphates and terminates the signal. more...

(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) We compared gene expression by microarray analysis between wild type and transgenic sibling progeny from two primary transgenic lines containing a construct for knocking down expression of both tomato fruitfull orthologs, FUL1/TDR4 and FUL2/MBP7.

(Submitter supplied) We performed transcriptome analyses throughout fruit development using the tomato cultivar M82 and its near-isogenic line IL8-3, with interesting and useful traits such as a high content of soluble solids. To identify genes that show differential expression between M82 and IL8-3 fruits, we used a custom microarray containing 43,803 tomato probes. Some genes, such as cell wall invertase and sucrose synthase genes, which are encoded by LIN6 (Solyc10g083290) and TOMSSF (Solyc12g009300) respectively, are well known to play a key role in the sink function of fruit. more...

(Submitter supplied) The transformation of the ovary into a fruit after successful completion of pollination and fertilization has been associated with many changes at transcriptomic level. These changes are part of a dynamic and complex regulatory network that is controlled by phytohormones, with a major role for auxin. One of the auxin-related genes differentially expressed upon fruit set and early tomato fruit development is Solanum lycopersicum ARF9 (SlARF9). more...

(Submitter supplied) Transgenic tomato (Solanum lycopersicum) plants expressing a fragment of the SlSIOGDH gene encoding subunit E1 of the 2-oxoglutarate dehydrogenase protein complex in the antisense orientation and exhibiting considerable reductions in the activity of this enzyme exhibit a considerably reduced rate of respiration. They were, however, characterised by largely unaltered photosynthetic rates and fruit yield but a restricted leaf, stem and root growth rate. more...

(Submitter supplied) Fruits of transgenic tomato (Solanum lycopersicum) plants engineered with ripening-induced, yeast S-adenosylmethionine decarboxylase (ySAMdc) gene, accumulate the higher polyamines spermidine (Spd) and spermine (Spm) and demonstrate ameliorated phytonutrient content, juice quality, and prolonged vine life. Enhanced nitrogen-carbon interactions were revealed by comprehensive Nuclear Magnetic Resonance (NMR) spectroscopy-based metabolite profiling of the transgenics, suggesting that Spd and Spm are perceived as nitrogenous metabolites by the fruit cells (Mattoo et al., 2006). 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) 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...
