Project description:ASR1 is a transcription factor widely present in plants that is involved in stress responses. In this work, we have silenced ASR1 in tomato fruits using an anti-sense construct and analysed the gene expression in two independent transgenic lines (AS5 and AS17) and in wild-type (WT) fruits.

Project description:The tomato (Solanum lycopersicum) MADS-box transcription factor RIPENING INHIBITOR (RIN) acts as a master regulator of tomato fruit ripening. We previously identified a direct RIN target gene Solyc07g052960, which encodes a putative GRAS family protein belonging to the SHORT-ROOT (SHR) branch, but its role was unknown. RNA interference (RNAi)-mediated gene silencing reduced Solyc07g052960 expression in transgenic fruits, but the fruits appeared to ripen normally. However, the transgenic fruits at the ripening stage showed a marked decrease of the expression levels of several ripening-induced genes, especially involved in cell wall modification and secondary metabolism. This suggests that Solyc07g052960 participates in the regulation of these processes as one component of the RIN-activated transcriptional cascade regulating fruit ripening in tomato.

Project description:An Ac/Ds transposon tagged mutant population was screened for changes in visible fruit phenotypes. One line showed orange, yellow sectors in the fruit and was named Orange ripening (Orr), its transposase free offspring showed Mendelian segregation yielding red, yellow and orange fruit bearing plants in a ratio of 1:2:1. Crossing the an orange fruit plant line to the wild-type yielded only plants bearing yellow fruit. A cross between the yellow fruit bearing progeny yielded 26 plants having red and 17 plants having yellow fruit, suggesting an over-dominant allele. Using inverse PCR analysis showed an insertion in the putative subunit M of the tomato Ndh complex. Subsequently, an Orr Ds transposon excision line was recovered which only showed red pigmented fruit. Here, we describe microarray profiling of tomato fruits from wild-type, heterozygous and homozygous Orr insertion plants and from fruits harvested from the Orr excision line. Keywords: mutant wild type Tomato fruits were harvested at breaker stage using wild-type, ORR homozygouse and heterozygous lines as well as Orr excision lines. To investigate the expression changes in the ORR mutants, wildtype and ORR mutant line fruits were harvested at the breaker stage and subjected to Affymetrix microarray profiling

For a preliminary screening, we monitored global gene expression in tomato fruits from untransformed control (Ailsa Craig [AC] cultivar) and three transgenic lines with Solyc07g052960 knockdown by RNAi (lines T-7, T-22 and T-23) at the ripening (pink coloring) stage using microarray without biological replication.

Project description:Mature green fruits of the tomato (Solanum lycopersicum L.) cultivar John Baer and Pearson were investigated (fruit developmental category II). John Baer wild type, John Baer LA0063 and Pearson wild type, Pearson 2-303 fruits were used. Tomato mutant plants LA0063 and 2-303 were positional sterile (PS mutants). Samples contained exclusively the fruit peel, which was removed with a scalpel to a depth of approximately 1 mm. After sampling point the plant material was immediately frozen in liquid nitrogen and stored at -80 C until use.

Project description:The steroid hormone brassinosteroids (BRs) play considerable roles in plant development and defence. Harnessing the extensive knowledge on Arabidopsis BR signalling network for improving productivity in crop species requires first to identify the conserved network components and their function in the target species. To investigate the function of SlBIM1a, the tomato closest homolog of AtBIM1, which is highly expressed in the developing fruit, we generated transgenic tomatoes, which overexpress or down-regulate SlBIM1a gene. Main alterations were observed in SlBIM1a overexpressing lines, which displayed a severe plant and fruit dwarfism. To unravel the molecular basis of phenotypical modifications in SlBIM1a overexpressing fruits, a microarray (Agilent) analysis was performed on Pro35S:SlBIM1aOX and WT fruits harvested at 15 DPA.
