Hyperspectral leaf reflectance of grasses varies with evolutionary lineage more than with site

Ecosphere
To predict ecological responses at broad environmental scales, grass species are commonly grouped into two broad functional types based on photosynthetic pathway.

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 ...

Evolution and diversification of the momilactone biosynthetic gene cluster in the genus Oryza. [PDF]

New Phytol
Summary Plants are master chemists and collectively are able to produce hundreds of thousands of different organic compounds. The genes underlying the biosynthesis of many specialized metabolites are organized in biosynthetic gene clusters (BGCs), which is hypothesized to ensure their faithful coinheritance and to facilitate their coordinated ...

Traversing the effects of ploidy changes in different Eragrostis curvula genotypes through high-throughput RNA sequencing. [PDF]

Plant Genome
Abstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas. [PDF]

Am J Bot
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Pollen morphology of the Chloridoideae (Gramineae) [PDF]

Grana, 2004
Pollen grains of 57 species (representing 42 genera) of the Chloridoideae have been investigated using light, scanning and transmission electron microscopy. Two aperture patterns and nine exine patterns are distinguished using SEM and TEM. These are categorized into five pollen types. Two pollen types are previously not recorded in Gramineae. A key for
