Transcriptome Assembly and Comparison of an Allotetraploid Weed Species, Annual Bluegrass, with its Two Diploid Progenitor Species, Poa supina Schrad and Poa infirma Kunth
Annual bluegrass ( Poa annua L.) is one of the most widespread weed species in this world. As a young allotetraploid, P. annua has occupied diverse environments from Antarctic area to subtropical regions. To unveil the evolutionary mystery behind P. annua 's wide distribution, extensive adaptab...

Annual bluegrass ( Poa annua L.) is one of the most widespread weed species in this world. As a young allotetraploid, P. annua has occupied diverse environments from Antarctic area to subtropical regions.
