Recorded summary

Experiments link polar auxin transport to the positions of new plant organs. Existing primordia act as auxin sinks, helping define the spacing and stability of phyllotactic patterns.

Recorded limitations

This is mechanistic context for plant pattern formation. It does not establish a universal Fibonacci mechanism across organisms or molecular systems; appraisal here is limited to the abstract and publisher metadata.

Evidence and provenance

Chapter Trust Factor uses a minimum of three distinct qualifying studies. Publication records retain their own evidence and assessment.
