“…In addition to its importance as a crop plant, tomato is an excellent model system for the analysis of hormonal and environmental signal transduction components involved in fruit ripening, metabolic regulation, and plant-pathogen interactions (AdamsPhillips et al, 2004;Alexander and Grierson, 2002;Arie et al, 2007). During tomato fruit ripening, it has been found that the glutamate concentration is much higher than that of other amino acids (Boggio et al, 2000).…”

“…It includes fruit bearing vegetables (tomato and pepper), tuber-bearing potatoes, plants with edible leaves (Solanum aethiopicum, S. macrocarpon), medicinal (Datura), and ornamental plants (Petunia, Nicotiana) (Knapp 2002). In addition to its agricultural utility, tomato is an excellent model system to study hormonal and environmental signal transduction components active in fruit ripening, metabolic regulation, and plant-pathogen interactions (Alexander and Grierson 2002;Adams-Phillips et al 2004;Arie et al 2007). Till date, several ERF genes have been characterized in tomato that includes Pti4, 5, 6 (Zhou et al 1997;Gu et al 2002), Sl-ERF2 (Pirrello et al 2006;Zhang et al 2009), TERF1 (Huang et al 2004, TSRF1 , JERF1 (Zhang et al 2004a), JERF3 (Wang et al 2004), andLeCBF1-3 (Zhang et al 2004b).…”

Ethylene responsive transcription factors have been shown to be intimately connected to plant development, defense responses and stress signaling pathways and in order to use them for plant improvement, we need to have better understanding of these proteins. In this study, 85 ERF genes have been identified from tomato using raw EST data in various public repositories. Phylogenetic analysis with tomato ERF domains revealed their distribution in all the groups, previously identified in model systems. MEME motif analysis resulted in identification of conserved domains, characteristic to member of each clade, in addition to ERF domain. Expression analysis during vegetative and reproductive stages of development using QPCR and tomato GeneChip arrays, revealed their tissue-specific/preferential accumulation. In total, 57 genes were found to be differentially expressed during temporal stages of tomato fruit development. The expression analysis of 23 ERF family genes representing each clade in response to seven abiotic stress treatments revealed their differential expression in response to more than one abiotic stress treatments. Results suggest that ERF genes play diverse roles in plant's life and comprehensive data generated will be helpful in conducting functional genomics studies to understand their precise role during plant development and stress response.

“…Similar to other defensive secondary metabolites, SAs are part of the coevolution between plants and pathogens (Morrissey and Osbourn, 1999;Arie et al, 2007). Several fungal and bacterial species possess tomatinases that are capable of removing part or even the entire lycotetraose structure from tomatine.…”

GLYCOALKALOID METABOLISM1 Is Required for Steroidal Alkaloid Glycosylation and Prevention of Phytotoxicity in Tomato

et al. 2011

Steroidal alkaloids (SAs) are triterpene-derived specialized metabolites found in members of the Solanaceae family that provide plants with a chemical barrier against a broad range of pathogens. Their biosynthesis involves the action of glycosyltransferases to form steroidal glycoalkaloids (SGAs). To elucidate the metabolism of SGAs in the Solanaceae family, we examined the tomato (Solanum lycopersicum) GLYCOALKALOID METABOLISM1 (GAME1) gene. Our findings imply that GAME1 is a galactosyltransferase, largely performing glycosylation of the aglycone tomatidine, resulting in SGA production in green tissues. Downregulation of GAME1 resulted in an almost 50% reduction in a-tomatine levels (the major SGA in tomato) and a large increase in its precursors (i.e., tomatidenol and tomatidine). Surprisingly, GAME1-silenced plants displayed growth retardation and severe morphological phenotypes that we suggest occur as a result of altered membrane sterol levels caused by the accumulation of the aglycone tomatidine. Together, these findings highlight the role of GAME1 in the glycosylation of SAs and in reducing the toxicity of SA metabolites to the plant cell.
