| Does lack of available suitable habitat explain the patchy distributions of rare calcicole fern species? |
| The Ca concentrations in calcifuge and calcicole plants growing in their natural habitats differ markedly. |
| Within the shoot, the control of Ca is a major tolerance mechanism of calcicole species and its partitioning might provide another potential screen. |
| We will identify genes that are differentially expressed between calcicolous and non-calcicolous ecotypes of A. thaliana and determine their role in the calcicole phenotype. |
