| Abstract/Contents: | "Annual bluegrass (Poa annua L. ) displays a wide range of range of life history characteristics, from wild weedy annual-types to long-lived perennial types (also known as greens-types), enables it to adapt to a wide range of environmental conditions and diverse habitats world-wide. Researchers at Penn State University investigated the genetics of annual bluegrass (Poa annual [annua] L.) in an effort to understand this complex species. The study found: Greens-type Poa annua plants are characterized by single branching inflorescences and reduced culm, tiller, leaf, and panicle lengths compared to annual-type Poa annua plants. A single recessive genetic mechanism is hypothesized to control the differences between greens-type and annual-type Poa annua. However, the genetic inheritance of greens-type Poa annua phenotype does not follow the Laws of Mendelian inheritance in advanced generations. Greens-type Poa annua plants were observed to vegetatively revert to annual-types over time when not mowed. We conclude that the greens-type Poa annua phenotype is likely to be epigenetically controlled and, as such, the greens-type Poa annua phenotype is not stable outside of its greens management environment." |
