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.

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

Microparticles from dental calculus disclose paleoenvironmental and palaeoecological records. [PDF]

Ecol Evol
Dental calculus analysis reveals evidence about past dietary ecology and plant diversity. This multi‐proxy study focuses on pollen and non‐pollen palynomorphs. We detected plants referable to woody habitats and warm‐temperate climates. Clues about past ecological and environmental issues of Central Italy were found.

Lateral transfers lead to the birth of momilactone biosynthetic gene clusters in grass

The Plant Journal, Volume 111, Issue 5, Page 1354-1367, September 2022., 2022
SUMMARY Momilactone A, an important plant labdane‐related diterpenoid, functions as a phytoalexin against pathogens and an allelochemical against neighboring plants. The genes involved in the biosynthesis of momilactone A are found in clusters, i.e., momilactone A biosynthetic gene clusters (MABGCs), in the rice and barnyardgrass genomes.

Ecophysiological traits of grasses: resolving the effects of photosynthetic pathway and phylogeny [PDF]

, 2009
C4 photosynthesis is an important example of convergent evolution in plants, having arisen in eudicots, monocots and diatoms. Comparisons between such diverse groups are confounded by phylogenetic and ecological differences, so that only broad ...
