Maternal Effects on Postembryonic Neuroblast Migration in C. elegans

Hoikiu Poon, Chaogu Zheng

The paper shows that maternal dpy-19 mRNA persists into larval stages to regulate postembryonic neuroblast migration, and this effect can be rescued by either maternal or zygotic gene copies.

Functional Interrogation of Neuronal Subtypes via Intersectional Expression of Optogenetic Actuator Reveals Non-linear Components in a Linear Circuit

Tiannuo Li, Sandeep Kumar, Hoikiu Poon…·Chaogu Zheng

The paper uses a split GAL4-based genetic AND gate to optogenetically interrogate specific touch receptor neuron subtypes in C. elegans, revealing non-linear components in a seemingly linear neural circuit.
