Nordic Journal of Botany, EarlyView.The genus Hordeum (Poaceae), of the tribe Triticeae, comprises approximately 32 species with substantial potential for barley improvement. Hordeum vulgare is an economically important cereal widely cultivated across diverse environments, from the Arctic to desert and humid regions.

PLANTS, PEOPLE, PLANET, EarlyView.Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

The role of genomic structural variation in the genetic improvement of polyploid crops
Crop Journal, 2019 Many of our major crop species are polyploids, containing more than one genome or set of chromosomes. Polyploid crops present unique challenges, including difficulties in genome assembly, in discriminating between multiple gene and sequence copies, and ...

Mining transcriptomic data to study the origins and evolution of a plant allopolyploid complex [PDF]
PeerJ, 2014 Allopolyploidy combines two progenitor genomes in the same nucleus. It is a common speciation process, especially in plants. Deciphering the origins of polyploid species is a complex problem due to, among other things, extinct progenitors, multiple ...

A carbohydrate-binding protein, B-GRANULE CONTENT 1, influences starch granule size distribution in a dose-dependent manner in polyploid wheat [PDF]
, 2020 In Triticeae endosperm (e.g. wheat and barley), starch granules have a bimodal size distribution (with A- and B-type granules) whereas in other grasses the endosperm contains starch granules with a unimodal size distribution.

Past, present and future of local crop evolution
PLANTS, PEOPLE, PLANET, EarlyView.Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Gene turnover in the common ancestor of all C4 grasses
PLANTS, PEOPLE, PLANET, EarlyView.Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all
