Historic rewiring of grass flowering time pathways and implications for crop improvement under climate change

New Phytologist, Volume 245, Issue 5, Page 1864-1878, March 2025.
Summary Grasses are fundamental to human survival, providing a large percentage of our calories, fuel, and fodder for livestock, and an enormous global carbon sink. A particularly important part of the grass plant is the grain‐producing inflorescence that develops in response to both internal and external signals that converge at the shoot tip to ...

A nuclear phylogenomic tree of grasses (Poaceae) recovers current classification despite gene tree incongruence

New Phytologist, Volume 245, Issue 2, Page 818-834, January 2025.
Summary Grasses (Poaceae) comprise c. 11 800 species and are central to human livelihoods and terrestrial ecosystems. Knowing their relationships and evolutionary history is key to comparative research and crop breeding. Advances in genome‐scale sequencing allow for increased breadth and depth of phylogenomic analyses, making it possible to infer a new

Inflorescence diversity in subtribe Eleusininae (Poaceae: Chloridoideae: Cynodonteae)

Flora, 2017
Abstract We studied the inflorescences of 112 members of tribe Chloridoideae subtribe Eleusininae from a morphological and evolutionary perspective to identify the most frequent types and to explore the evolutionary history of selected inflorescence associated characters.
