What is the core benefit of these studies?
We describe here morphologically rapidly changing ecotypes in the genus Diplacus (Mimulus aurantiacus).
By "rapidly changing" is meant within ten to 15 years.
Is the plasticity of the flowers only morphologically or also genetically fixed? It would be best if you understood this morphologically alter of the shape in the real sense. Any one plant in a transition belt may change the floral and non-floral properties on an individual base. All plants together within this belt show generally the same trend when time goes by.
Is it also genetically expressed? Yes, that is correct.
How do we imagine that? We can check the main transcription factors that regulate floral and pigment properties of the flowers. They alter their regulating activities and their genetic imprint slightly according to environmental needs. It is an active, time - and energy-consuming process that brings about adaptation for the whole plant populations in question.
Evolution in this species is mainly related to gene regulation, which alters in the context of environmental demand and is also hereditary. With this speed, populations of Diplacus aurantiacus are currently altering their floral traits in the so-called «hybridization zone».
We are about to step further and will promote this idea far beyond of the genus Diplacus. see -> OTHER PLANTS
