on. Here I describe two approaches for analysis of meiotic cohesion in . The first approach relies on cytology to detect and quantify defects in SCC. The second approach relies on PCR and restriction digests to identify embryos that inherited an incorrect complement of chromosomes due to aberrant me

N use efficieny and amino acid transport in rape (, L.)om source cell cytosol to phloem sap. The amino acid content of whole leaves decreases with age. To analyse how this finding relates to export of reduced N from the leaves, investiagtions on amino acid transporter gene expression during leaf development are in progress.

Context-Free Graph Grammars, of context-free graph grammars are discussed. Other, equivalent, ways of defining context-free graph languages are: generating graph expressions by regular tree grammars, and translating trees into graphs by formulas of monadic second-order logic. Context-free graph grammars can be used to generate string languages and tree languages.
