RNA sequencing of tomato (distal 1cm) root tips exhibiting transgenerational adaptation to aluminum stress

Soil acidification and associated aluminum toxicity are environmental factors threatening agriculture and food security. Tomato, as well as many other vegetable crops, are sensitive to acid (pH<5). Reduction in root growth is the typical symptom of aluminum toxicity. In our previous work, the third and fourth generation progenies of Al-treated tomato 'Micro tom' plants produced larger roots than non-treated plants. The goals of this project are to identify aluminum stress-induced transcriptome changes, and to develop understanding of the molecular mechanisms which drive the transgenerational adaptation process.
