Project code: 0313149B
Contract period: 01.09.2004 - 31.08.2007
Budget: 230,670 Euro
Purpose of research: Basic research

Plant meristems initiate all parts of the plant and play a major role in the establishment of plant architecture. The project aims at exploiting natural diversity in meristem activity and organization within the Solanaceae family to gain insight into the mechanisms underlying meristem function. Knowledge derived from Arabidopsis will be directly applied to plants of the Solanaceae family, including species of great economical importance like tomato and potato, to enable the study of specific developmental programs such as tuber formation. To achieve these goals the following studies will be conducted: 1) Comparative analyses between Arabidopsis and the Solanaceae family will be performed by analyzing the expression of promoter-reporter gene fusions and by over-expressing the corresponding regulatory genes. Normalized meristem-specific libraries will be prepared and dedicated meristem-chips will be produced. Transcriptome analyses will be performed on those microarrays to obtain general insights in the patterns of gene expression characteristic for the different meristems. Subsequently, a thorough functional analysis will be performed by de-regulation of candidate gene expression using tissue-specific promoters, to define regulatory pathways common to all meristematic cells and specific networks to specialized meristems.
