Expression data from leaflets of domesticated tomato and wild-related Solanum pennellii plants subjected to water stress

Project description:Transcriptomics study which main goal is to elucidate the programme of gene expression triggered by water stress in leaflets of the drought-tolerant wild-related tomato Solanum pennellii (acc. PE47) compared with domesticated tomato (S. lycopersicum, cv. P73). In this study we used S. lycopersicum (Sl) (cv. P73) and S. pennellii (Sp) (acc. PE47) species displaying remarkable divergences regarding drought tolerance, to investigate the physiological and molecular responses in leaves of plants grown without stress (control) and after four days of water withholding (water stress, WS), when plant water loss was significant but leaves did not show visual dehydration symptoms yet. Significant physiological differences between species were found, showing Sp leaves higher ability to avoid water loss. Leaf transcriptomic analysis showed important constitutive expression differences between Sp and Sl, including genes with unknown function. In relation to the genes specifically induced by drought in Sp, those linked to stomatal closure, cell wall and primary carbohydrate metabolism and, specially, nitrogen metabolism were identified. Thus, genes linked to NH4+ assimilation, GOGAT/GS cycle and the GDH- and GABA-shunt were specifically induced by water stress in leaves of Sp. Our results showed also the up-regulation in Sp of genes involved in JA biosynthesis pathway, which were induced in both conditions, whereas genes involved in ET biosynthesis were specifically induced under WS. Regarding ET signaling, ERF genes were up-regulated by WS in Sp, hinting at the importance of these transcriptional regulators in the drought response of Sp.
