Weedy Adaptation in Setaria spp.: VIII. Structure of Setaria faberi Seed, Caryopsis and Embryo Germination
Giant foxtail (Setaria faberi) seeds differ in requirements for germination. Variable germinability arises during seed development under the influence of genotype, environment and parent plant. Giant foxtail seed germination has been shown to be regulated by independent asynchronous or dependent synchronous action of seed structures. To gain better insight into the process, germination was divi...
متن کاملSetaria Comes of Age: Meeting Report on the Second International Setaria Genetics Conference
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. Its close phylogenetic relationship with economically important crops such as maize and sorghum positions Setaria as an ideal model system for accelerating discovery and characterization of crop genes that control agronomically importan...
متن کاملWeedy Setaria Seed Life History
The nature of weeds is a complex adaptive, soil-seed communication system. The nature of weedy Setaria life history is an adaptable, changeable system in which complex behaviors emerge when self-similar plant components self-organize into functional traits possessing biological information about spatial structure and temporal behavior. The nature of the weedy Setaria is revealed in the physical...
متن کاملSetaria viridis and Setaria italica, model genetic systems for the Panicoid grasses.
Setaria italica and its wild ancestor Setaria viridis are diploid C(4) grasses with small genomes of ∼515 Mb. Both species have attributes that make them attractive as model systems. Setaria italica is a grain crop widely grown in Northern China and India that is closely related to the major food and feed crops maize and sorghum. A large collection of S. italica accessions are available and thu...
متن کاملWeedy Adaptation in Setaria spp.: VII. Seed Germination Heteroblasty in Setaria faberi
The dormancy status of S. faberi seed at abscission was assessed with reference to tiller and panicle development. Seed from a single genetic line were grown under field, greenhouse and controlled environment growth chamber conditions. At abscission, a small fraction (<10%) of S. faberi seed germinated under favorable conditions. Seed were dissected and germination of caryopses and embryos also...
