The Beixin Culture archaeobotanical evidence from Guanqiaocunnan indicates a population dispersal of hunter-gatherercultivators into and across the Haida region of northern China [PDF]

open access: yes, 2020
The Beixin Culture appears within the hilly southwestern area of the Haidai region of northern China at ca. 5000 BC, and spreads to its north and northeast flood plains in the following millennium, replacing the Houli Culture.

Abscission zone development in Setaria viridis and its domesticated relative, Setaria italica [PDF]

open access: yesAmerican Journal of Botany, 2016
PREMISE OF THE STUDY:Development of an abscission zone (AZ) is needed for dispersal of seeds, and AZ loss was a critical early step in plant domestication. The AZ forms in different tissues in different species of plants, but whether the AZ is developmentally similar wherever it occurs is unknown.

Setaria Comes of Age: Meeting Report on the Second International Setaria Genetics Conference

open access: yesFrontiers in Plant Science, 2017
Setaria viridis is an emerging model for cereal and bioenergy grasses because of its short stature, rapid life cycle and expanding genetic and genomic toolkits.

Bacillus benefits the competitive growth of Ambrosia artemisiifolia by increasing available nutrient levels

open access: yesFrontiers in Plant Science, 2023
Bacillus can help plants to acquire nutrients either directly or indirectly. However, the role of Bacillus community on the competitive growth of invasive Ambrosia artemisiifolia is poorly understood.

A simple and highly efficient Agrobacterium-mediated transformation protocol for Setaria viridis

open access: yesBiotechnology Reports, 2015
The production and use of sugarcane in Brazil is very important for bioenergy production and is recognized as one of the most efficient in the world. In our laboratory, Setaria viridis is being tested as a model plant for sugarcane. S.

Insights from controlled, comparative experiments highlight the limitations of using BSMV and FoMV for virus‐enabled reverse genetics in rice

open access: yesAnnals of Applied Biology, EarlyView.
Virus‐enabled reverse genetics (VERG) enables transient gene expression modulation in plants but its efficacy varies across species. We evaluated the efficacy of barley stripe mosaic virus (BSMV) and foxtail mosaic virus (FoMV) for virus‐induced gene silencing (VIGS) and virus‐mediated overexpression (VOX) in rice (Oryza sativa).

Fitness costs associated with evolved herbicide resistance alleles in plants [PDF]

open access: yes, 2009
Predictions based on evolutionary theory suggest that the adaptive value of evolved herbicide resistance alleles may be compromised by the existence of fitness costs.
