Evolutionary analysis of ascorbate-glutathione cycle genes across green plants with lineage-specific profiling in grapevine (Vitis vinifera L.) Abstract. Ascorbate-glutathione (AsA-GSH) cycle genes are vital for plant processes like stomatal regulation, nutrient uptake, and stress responses. Howeve

Floral syndromes in Aquilegia (Ranunculaceae) are associated with nectar- but not pollen-collecting pollinators AbstractBackground and Aims. Plant–pollinator interactions span a continuum from strict specialization to generalization and most flowers are visited by mo

🌸Takeaway: In Aquilegia, nectar-collecting pollinators appear to be the main evolutionary drivers of floral form, perhaps because they’re more efficient pollinators. (9/9)
