Methods for Performing Crosses in Setaria viridis, a New Model System for the Grasses

2013
We have developed a methodology for performing crosses in Setaria viridis (S. viridis). The method involves pruning the panicle prior to a hot water treatment to kill viable pollen. Crosses are performed following a well-controlled growth regime and typically result in the recovery of 1 to 7 cross-pollinated seed/s per panicle.

Excavation of plant roots from the field as well as processing of samples into endosphere, rhizosphere, and soil are described in detail, including DNA extraction and data analysis methods. This paper is designed to enable other laboratories to use these techniques for the study of soil, endosphere, and rhizosphere microbiomes.

A PCR-based Genotyping Method to Distinguish Between Wild-type and Ornamental Varieties of Imperata cylindrica

We provide a cost-effective and rapid molecular genotyping protocol that employs variety-specific PCR primers that target DNA sequence differences within the chloroplast trnL-F spacer region to differentiate between varieties of Imperata cylindrica (cogongrass) that cannot be distinguished by morphology alone. These varieties include the federally listed noxious weed, cogongrass and closely-related, wide-spread ornamental variety, I. cylindrica var. koenigii (Japanese blood grass).

We present methods to evaluate how predation risk can alter the chemical quality of herbivore prey by inducing dietary changes to meet demands of heightened stress, and how the decomposition of carcasses from these stressed herbivores slows subsequent plant litter decomposition by soil microbes.
FAQs
C4 photosynthesis helps barnyardgrass maintain carbon gain when light is strong, temperatures are warm, and water is limited. This pathway is therefore linked to the rapid growth observed in seedlings occupying disturbed fields. In biological studies, the trait provides a framework for examining how carbon fixation contributes to establishment and competitive performance under contrasting environmental conditions.
Its competitive effect arises from simultaneous demands for light, nutrients, and water. When barnyardgrass grows alongside rice or other crops, access to these shared resources can reduce crop productivity. Studying this interaction connects plant growth biology with agricultural outcomes, because the weed’s establishment and resource capture help explain why dense infestations complicate field management.
Because barnyardgrass reproduces primarily through abundant seeds, population presence can be examined through seed production and seedling establishment, especially in disturbed fields. This links its life cycle to adaptation and persistence: successful establishment allows the weed to appear where crop competition and management create openings. The biology is useful for studying annual plant population dynamics.
Variable herbicide responses make barnyardgrass useful for examining plant evolution and resistance. Comparing how populations respond to herbicide treatments can help researchers investigate differences in susceptibility and the biological consequences of selection. This context also supports efforts to develop sustainable weed-control strategies rather than relying on a single uniform management approach.
Rice fields provide an important context for examining how barnyardgrass growth influences crop productivity. Investigations can focus on the weed’s competition for light, nutrients, and water, then relate those interactions to management challenges. This application connects plant biology with agriculture by showing how growth, adaptation, and competition affect outcomes in a major crop environment.
Barnyardgrass combines rapid seedling growth, abundant seed reproduction, resource competition, and variable herbicide responses. Together, these traits create a useful system for linking plant adaptation with practical management problems. Research can use this biological context to consider how evolutionary responses and crop competition should inform more sustainable approaches to controlling agricultural weeds.
