Reaction-diffusion theory and intracellular differentiation

Reaction-diffusion theory and intracellular differentiation

The scope of reaction-diffusion theory comprises both intracellular and multicellular domains. I distinguish between two meanings of the word "morphogen" and discuss briefly events probably involving Turing morphogens in chemical reactions, animals, and slime molds. Three examples from the...

Zusammenfassung:The scope of reaction-diffusion theory comprises both intracellular and multicellular domains. I distinguish between two meanings of the word "morphogen" and discuss briefly events probably involving Turing morphogens in chemical reactions, animals, and slime molds. Three examples from the plant kingdom are discussed more extensively: repeated dichotomous branching in Micrasterias; whorl formation in Acetabularia; and unequal cell division in the cyanobacterium Anabaena catenula.
