Modes and cuts in metabolic networks: Complexity and algorithms [PDF]

Biosystems, 2009
Constraint-based approaches recently brought new insight into our understanding of metabolism. By making very simple assumptions such as that the system is at steady-state and some reactions are irreversible, and without requiring kinetic parameters, general properties of the system can be derived. A central concept in this methodology is the notion of

The mode of inheritance in tetraploid cut roses [PDF]

Theoretical and Applied Genetics, 2012
Tetraploid hybrid tea roses (Rosa hybrida) represent most of the commercial cultivars of cut roses and form the basis for breeding programmes. Due to intensive interspecific hybridizations, modern cut roses are complex tetraploids for which the mode of inheritance is not exactly known.
