Origins Under the Blowtorch: Frequent Fire Shifts the Balance Between Sunda-Origin and Sahul-Origin Plant Species in a Tropical Savanna. [PDF]

Ecol Evol
We examined the effect of fire frequency on the composition of vegetation of different biogeographic origins, to understand how frequently an ecosystem can be subject to fire but still retain its evolutionary diversity. There was dramatic structural and biogeographic change in less than 20 years from dry tropical woodlands into savannas, creating ...

Mechanical Strength: An Unrecognised Target in the Genetic Improvement of Crops. [PDF]

Plant Biotechnol J
ABSTRACT Leaf angle (LA) is a crucial agronomic trait influencing planting density and crop yield. Previous research highlighted the importance of cellular variations in the ligular region for determining LA, but the underlying regulatory mechanisms remain unclear.

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

New Phytol
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

Lateral gene transfer generates accessory genes that accumulate at different rates within a grass lineage

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.

Exploration of nutritional, pharmacological, and the processing trends for valorization of finger millet (Eleusine coracana): A review

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.

Carbon isotope values for grasses in Madagascar's Central Highlands establish baselines for historical and paleoecological research

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 ...

The contemporary distribution of grasses in Australia: A process of immigration, dispersal and shifting dominance

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.
