Trait transitions in explicit ecological and genomic contexts: plant mating systems as case studies

Area of Science:

• Evolutionary Biology
• Genomics
• Plant Science

Background:

• Plant sexual reproduction exhibits remarkable diversity, offering insights into evolutionary transitions.
• The study of plant mating systems is crucial for understanding evolutionary processes.

Purpose of the Study:

• To review how genomic data advances the testing of ecological and evolutionary theories on plant mating systems.
• To highlight recent discoveries in the genetic control of mating systems across various plant species.
• To explore the interplay between mating system evolution and genome evolution.

Main Methods:

• Analysis of extensive genomic datasets.
• Review of theoretical predictions from ecological and evolutionary theory.
• Examination of recent discoveries in model and non-model plant species.

Main Results:

• Genomic approaches are enabling rigorous testing of long-standing theories on plant mating systems.
• Complex interactions between mating system genes and genome evolution have been revealed.
• Major mating system transitions are often linked to significant ecological changes.

Conclusions:

• Genomic and ecological approaches are increasingly integrated to understand plant mating system evolution.
• Significant unsolved questions and future conceptual developments are identified for the field.
