New study from our lab led by former graduate student Shen Tian on the discovery of a "plasticity gene".

Here is a very detailed examination on how pigmentation in the cuticle of a butterfly wing scale changes the density and refractive index of chitin and, thus, also alters structural color.

For those interested in the evolution of phenotypic plasticity - Shen Tian et al. found that a novel bit of DNA - a Hox gene promoter in the genome of satyrid butterflies - boosts plasticity in the size of their eyespots in response to temperature. https://t.co/9Y0ldnDo1T

Adaptive phenotypic plasticity allows organisms to display distinct phenotypes in response to variable environments, but little is known about the genomic changes that promote the evolution of...

Butterfly larvae can pass on a learned odor preference to other larvae via a simple hemolymph transfusion. Short film about the work (published today) by my daughter Florence: https://t.co/Ei7Sx5sWO0

Did you realize that butterflies hear, and being able to hear the presence of a competitor increases mating success? https://t.co/Tm6ELj0kX8

I am looking for an enthusiastic student who wants to perform research on sound communication in butterflies, or on odor learning in butterfly larvae, at the organismal and/or molecular levels (e.g., brain circuitry and single-cell gene expression levels). Fellowship available!

Glad to share my last thesis chapter! We show that a 22nt micro-RNA controls melanic wing patterns in Lepidoptera https://t.co/YDBtweAftU

A long-standing question in biology is how phenotypic variation is generated from genetic variation. In Lepidoptera (butterflies and moths), an enigmatic genomic region containing the protein-coding...

Ever wonder about the evolutionary origin of caterpillar abdominal legs? They seem to derive from an endite GRN. https://t.co/Z1rj8v3CWi
news.nus.edu.sg
Adult insects, including butterflies and moths, typically have only three pairs of legs. But the existence of extra legs in caterpillars – chubby abdominal appendeages also known as ‘prolegs’ – has...

NUS researchers propose that the causes of eye colour variation in primates may, in part, be explained by differences in lighting in the habitats of primate species. https://t.co/Zg1PXOOeBY

It also proposes that hotspot loci of evolution happen primarily in genes that have been modularized, anywhere in a gene-regulatory network.
