The ryegrass mosaic virus (RgMV) is a single positive-strand RNA virus belonging to the genus Rymovirus. The major natural hosts for RgMV are members of the Gramineae species, including ryegrass. Here, we report the nearly complete genome sequence of RgMV by de novo assembly using ryegrass transcriptomes.

Understanding forage quality and the factors that affect its constituents will help improve livestock production by making decisions that optimize forage nutritive value and intake. This investigation was conducted in Zagros semi-arid rangeland center, Iran to determine forage quality of several grass and legume species. Samples were collected at early bloom, from 5 m long and 0.10 m wide strip...

Studies of this nature may yield additional information which will aid in the proper placement of puzzling genera within the large and taxonomically difficult grass family. Summary.-It is suggested that the two types of root-hair development noted by Sinnott and Bloch within the Gramineae may have important taxonomic significance. Studies with additional genera are reported, and it is revealed ...

Recent investigations showed that most maize genes are present in compositional fractions of nuclear DNA that cover only a 1–2% GC (molar fraction of guanosine plus cytosine in DNA) range and represent only 10–20% of the genome. These fractions, which correspond to compositional genome compartments that are distributed on all chromosomes, were collectively called the ‘‘gene space.’’ Outside the...
