Integrative analysis of a specialized metabolic pathway across multiple non-model species illustrates mechanisms of emergence of chemical novelty in plant metabolism.
The shoot meristem becomes domed in shape during floral transition and this is controlled by flowering pathways and the phytohormone gibberellin causing increases in cell size and number.
The system that controls gene expression by the plant signaling molecule auxin has deep evolutionary roots, and stepwise increases in system complexity shaped the highly diverse auxin response in land plants.
A computational method to authenticate low-coverage ancient DNA experiments shows that putative wheat sequences from 8000 years old sediments are most likely not of ancient origin.
A fungal bioluminescence pathway can be reconstituted in planta to create luminescence in many plant species without external substrate addition, and be used to design customizable reporters of gene-expression.
