Občas se hodí mít stresované rodiče

Something good comes out from all bad by Vít Latzel.

The phenotype of all living organisms is conditioned by their genetic information and its interaction with environment. Nonetheless, during the past three decades it has been repeatedly shown that the phenotype expressed by an individual can also be affected by the parental environment, which is called parental effects. In the text I introduce the mechanisms of parental effects. I also summarize our research on plants, which revealed that mothers are able to affect photosynthesis of their progeny. Moreover, mothers can also “prepare” their progeny on disturbance event if they also experienced disturbance. I also discuss the possible role of parental effects in evolution of populations. At last I notice that stress experienced by parents or grandparents both in plants and animals may result in better performance of progeny contributing thus finally in enhanced fitness of starving (grand)parents.
