Furthermore, theoretical predictions have shown that selection, unlike genetic drift, strongly influences the distribution of network motifs. However, no difference in the frequency of loops and motifs regulating plastic genes compared to non-plastic genes has been observed. The topology of these networks may still be insufficiently understood to fully explain or predict the plasticity of gene expression.<\/pre>\n\n\n\n<pre id=\"tw-target-rmn\" class=\"wp-block-preformatted\">Apolline J R Petit , Anne Genissel , Arnaud Le Rouzic<br><\/pre>\n\n\n\n<p><a href=\"https:\/\/doi.org\/10.1093\/genetics\/iyag009\">https:\/\/doi.org\/10.1093\/genetics\/iyag009<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"501\" src=\"https:\/\/www.egce.universite-paris-saclay.fr\/wp-content\/uploads\/2026\/03\/Illustration_Petitetal_Genetics-1024x501.png\" alt=\"\" class=\"wp-image-21620\" srcset=\"https:\/\/www.egce.universite-paris-saclay.fr\/wp-content\/uploads\/2026\/03\/Illustration_Petitetal_Genetics-1024x501.png 1024w, https:\/\/www.egce.universite-paris-saclay.fr\/wp-content\/uploads\/2026\/03\/Illustration_Petitetal_Genetics-300x147.png 300w, https:\/\/www.egce.universite-paris-saclay.fr\/wp-content\/uploads\/2026\/03\/Illustration_Petitetal_Genetics-768x376.png 768w, https:\/\/www.egce.universite-paris-saclay.fr\/wp-content\/uploads\/2026\/03\/Illustration_Petitetal_Genetics-200x98.png 200w, https:\/\/www.egce.universite-paris-saclay.fr\/wp-content\/uploads\/2026\/03\/Illustration_Petitetal_Genetics.png 1388w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What are the properties of gene regulation in genes whose expression is sensitive to environmental factors (plastic genes), as opposed to genes whose expression is independent of the environment (non-plastic genes)?
