In situ protocol for butterfly pupal wings using riboprobes

Area of Science:

• Developmental biology
• Molecular biology
• Entomology

Background:

• In situ hybridization is crucial for studying gene expression patterns in developing tissues.
• Gene expression analysis at the transcriptional level is vital when protein-level studies are not feasible.
• Existing methods for butterfly wing development analysis are limited to larval stages.

Purpose of the Study:

• To present a video protocol for performing in situ hybridization on pupal wings of the butterfly Bicyclus anynana.
• To optimize in situ hybridization techniques for larger, more delicate pupal wings compared to larval wing discs.
• To provide a reliable method for analyzing gene transcription patterns in butterfly pupal wing development.

Main Methods:

• Development of a detailed video protocol for in situ hybridization.
• Utilization of riboprobes for detecting specific RNA transcripts.
• Optimization of the technique for the fragile Bicyclus anynana pupal wings.

Main Results:

• A comprehensive video protocol for in situ hybridization in butterfly pupal wings is now available.
• The protocol is optimized for the specific challenges of working with pupal wing tissues.
• Successful application of the method allows for detailed study of gene expression during pupal wing development.

Conclusions:

• The presented video protocol offers a valuable tool for researchers studying butterfly development.
• This technique enhances the ability to investigate gene function and spatial expression patterns in pupal wings.
• The optimized protocol addresses limitations of previous methods, particularly for fragile pupal tissues.
