A nuclear phylogenomic tree of grasses (Poaceae) recovers current classification despite gene tree incongruence. [PDF]
New PhytolSummary 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

New Phytologist, Volume 240, Issue 5, Page 2072-2084, December 2023., 2023 Summary Lateral gene transfer (LGT) is the movement of DNA between organisms without sexual reproduction. The acquired genes represent genetic novelties that have independently evolved in the donor's genome. Phylogenetic methods have shown that LGT is widespread across the entire grass family, although we know little about the underlying dynamics.

Food Science &Nutrition, Volume 11, Issue 11, Page 6802-6819, November 2023., 2023 Abstract High nutrient variability and food security are the needs of the hour. Millets may be as effective as other cereal crops for dealing with severe malnutrition and increasing global population problems. Due to their physiologically active components, millets have attracted more research interest.

PLANTS, PEOPLE, PLANET, Volume 5, Issue 6, Page 869-884, November 2023., 2023 Grasses are significant drivers of fires and are the primary food source for cattle in Madagascar's Central Highlands. However, their extent and importance to animals and people in the past remain poorly understood. Clarifying the history of Malagasy grasslands is necessary for building climate resilient food systems and supporting carbon stores that ...

Journal of Biogeography, Volume 50, Issue 9, Page 1639-1652, September 2023., 2023 Abstract Aim Little is known about the distribution of grasses throughout Australia. Using endemism as a basis for understanding biogeographical distributions, we hypothesised that contemporary species richness would be the result of environmental factors and dynamic ecological interactions spanning more than 25 Ma. Location Australia.

Diverse ecological functions and the convergent evolution of grass awns
American Journal of Botany, Volume 109, Issue 9, Page 1331-1345, September 2022., 2022 Abstract The awn of grasses is a long, conspicuous outgrowth of the floral bracts in a grass spikelet. It is known to impact agricultural yield, but we know little about its broader ecological function, nor the selective forces that lead to its evolution. Grass awns are phenotypically diverse across the extant ~12,000 species of Poaceae. Awns have been

Fate of Microplastic Captured in the Marine Demosponge Halichondria Panicea [PDF]
Marine Pollution Bulletin, 2023 Microplastic particles are widespread pollutants in the sea and filter-feeding sponges have recently been suggested as useful monitoring organisms. However, the fate of microplastic particles in sponges is poorly understood, yet crucial for interpreting monitoring data.

Temperature responses of Rubisco from Paniceae grasses provide opportunities for improving C3 photosynthesis [PDF]
Enhancing the catalytic properties of the CO2-fixing enzyme Rubisco is a target for improving agricultural crop productivity. Here, we reveal extensive diversity in the kinetic response between 10 and 37 \ub0C by Rubisco from C3 and C4 species within the

Collection Priorities of Pasture Genetic Resources in the Paniceae Native to South Africa [PDF]
, 2022 There is an urgent need for the prioritization and ex situ conservation of pasture grass species. Many pasture grasses are still in the process of domestication and grasslands in the tropical, subtropical, semi-arid and arid regions of the world are ...
