Project description: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.

Project description:Wild halophytic tomato has long been considered as an ideal gene donor for improving salt tolerance in tomato cultivars. Here, a wild tomato genotype, Solanum pimpinellifolium ‘PI365967’ is significantly more salt-tolerant than a cultivar, Solanum lycopersicom ‘moneymaker’. Affymetrix Tomato Genome Arrays was used to compare the transcriptome change of PI365967 and Moneymaker by salt treatment.After treatment with 200 mM NaCl for 5 h, PI365967 showed relatively fewer responsive genes compared to Moneymaker. Salt Overly Sensitive (SOS) pathway was found to be more active in PI365967 than in Moneymaker, coinciding with relatively less accumulation of Na+ in shoots of PI365967. A gene encoding salicylic acid-binding protein 2 (SABP2) was induced by salinity only in PI365967, suggesting a possible role of salicylic acid signaling in salt response of PI365967. The fact that two genes encoding lactoylglutathione lyase were salt-inducible only in PI365967, together with much higher basal expression of several glutathione S-transferase genes, suggested a more effective detoxification system in PI365967. Key words: salt tolerance, transcriptomic profiling, wild tomato, ion homeostasis, SABP2.

Project description:Expression data after flg22 treatment on leaf discs in Col-0, 35S:AFB1 and 35S:miR393 We used microarrays to investigated the effect of auxin signaling on flg22 response pathway. We also compared if addition of auxin could simulated the 35S:AFB1 phenotype. Keywords: stress response, disease state analysis

Project description:To evaluate the role of seeds in fruit quality, we induced parthenocarpy in tomato by regulating ovule-specific auxin synthesis or responsiveness using the INO promoter from A. thaliana, which is expressed in the outer layer of the integuments during early stages of ovule development. We compared these to fruit where the same coding regions were expressed from the DeFH9 promoter which is expressed in carpel tissues during early stages of ovule development. Expression of auxin synthesis or responsiveness genes by both of these promoters produced seedless parthenocarpic tomato fruit. We compared fruit samples using the Affymetrix tomato GeneChip (GPL4741) to determine how gene regulation and expression differed between wild-type and transgenic fruit. Keywords: genetic modification

Project description:Expression data after flg22 treatment on leaf discs in Col-0, 35S:AFB1 and 35S:miR393 We used microarrays to investigated the effect of auxin signalling on flg22 response pathway. We also compared if addition of auxin could simulated the 35S:AFB1 phenotype. Keywords: stress response, disease state analysis Leaf discs were taken and let overnight in water to avoid the wound response. We then performed the treatment (flg22, flg22 from Agrobacterium tumefaciens, flg22 +NAA, NAA) to the media. The samples where harvested and freeze in liquid nitrogen at 0, 1 and 2h after treatment.

In one treatment, 9 six-leaf-old plants of one tomato genotype (PI365967 or Moneymaker) were divided into three biological replicates and treated hydroponically under sterile condition with (or without) 200 mM NaCl for 5 h. RNA isolated from pooled three individual plants was used in hybridization to one chip, resulting in 12 chips in total.

Project description:The phytohormone auxin triggers transcriptional reprograming utilizing a well-characterized nuclear perception machinery. In contrast, mechanisms underlying other auxin effects, such as auxin feed-back on its transport, rapid regulation of ion fluxes or ultrafast global phospho-response, remain enigmatic. Auxin Binding Protein 1 (ABP1) has been contested as an auxin receptor candidate since decades. Here we show that a fraction of Arabidopsis thaliana ABP1 is secreted and binds auxin specifically at the acidic pH typical for the apoplast. ABP1 and its plasma membrane-localized partner, Transmembrane Kinase 1 (TMK1) are required for auxin-induced phosphorylation of about thousand proteins. Loss-of-function abp1 alleles but not complemented lines show defects in in vitro shoot regeneration and formation of auxin-transporting channels for vasculature formation and regeneration. These results support a role of ABP1-TMK1 in cell surface auxin perception mediating global auxin phospho-response and regenerative development.
