Plants that have grown in partnership with human activity in meadows can be a great source of seeds for restoration projects, but their ability to germinate is also a problem.

Coordination of leaf water supply and demand in aquatic and land plants
Is there a difference between emergent aquatic and terrestrial monocot herbs when it comes to coordination of leaf stomatal and vein traits?

Systematics of extinct grass species resolved with sequencing of 167-year-old herbarium specimen
The work is part of a trend of increasingly ambitious genetic work on old specimens.

Recent range expansion in Australian hummock grasses
Large-scale environmental changes such as aridification have shaped and continue to influence the evolution and composition of biomes. As conditions change, organisms may persist in some parts of their ranges, become...
Polyphyly of Arundinoideae (Poaceae) and awn evolution in the grasses
This study answers one of the last remaining big questions in grass taxonomy while highlighting examples of convergent evolution in an ecologically important trait, the hygroscopic, twisted geniculate awn.

Museomics reveal phylogeny of endangered Malagasy grasses
Poaceae is one of the most diverse families in Madagascar, but some lineages have not yet been assessed within a phylogenetic framework. This study focused on the threatened taxa of Chasechloa, historically associated...
Stable climate characterises hotspots of grass endemism
Glacial-interglacial climate cycles have far-reaching consequences for ecosystems and it is widely recognised that regions with a history of unstable climates have few endemic species and are susceptible to the...
Summer dormancy and seasonal growth in California perennial grasses
Superior drought survival is expected to result in reduced productivity and competitive ability, but this expectation has seldom been tested in herbaceous perennial species. Balachowski et al. quantified seasonal...
Polyphyletic relationships in Sorghum
Phylogenetic reconstruction techniques reveal evidence for a two-lineage polyphyletic ancestry of Sorghum within the larger Andropogoneae.
Flow sorting of C-genome chromosomes from Aegilops
This study uses flow sorting and FISH techniques to further the development of molecular tools to progress introgression breeding in wheat
Orinus as a case study for species delimitation in plants
Orinus as a model system: multiple approaches & lines of evidence are applied to determine species boundaries for plants in the Qinghai–Tibet Plateau.
Variations in apomixis in diploid Paspalum rufum
Under self-pollination induction three genotypes of P. rufum develop seeds from both meiotic and aposporous embryo sacs.
Polyploidy and long-distance dispersal
Most of the numerous and remarkable range disjunctions across the southern oceans are probably the result of occasional long-distance dispersal, rather than of vicariance. Linder and Barker study the grass subfamily...
M people and the ‘B’ word…
No, this is not an item about M People, an ‘English house music band which formed in 1990 and achieved success throughout most of the 1990s’, nor about using profane language… Anyway, how would any of that be...
