At each of these sampling points, which in the field were located by a hand-held GPS device (HOLUX M-241, Holux Technology Inc., Hsinchu, Taiwan), a spot with representative herbaceous cover and composition was chosen within a radius of 4 m.
Xylan was chosen as a model compound for hemicelluloses, and two kinds of agricultural wastes rice straw and palm shell were used as typical feedstocks representative of herbaceous and woody biomasses, respectively.
Therefore, the rate may be more representative of the herbaceous perennial ancestry in the clade than the derived woody perennial silversword lineage.
However, the Arabidopsis thaliana genome may not be representative of other herbaceous species, as it has undergone recent (<10Mya) large-scale rearrangements and DNA loss [ 20, 24].
Among the basal angiosperm families, only Aristolochiaceae contains highly accessible, easily cultivated herbaceous plants with features broadly representative of angiosperms in general.
LWP was defined as the maximum number of consecutive days where the water potential of at least one of the four mineral ("A") soil layers is higher than the permanent wilting point (-3 MPa) representative of the herbaceous plants along the aridity gradient.
Representative extinct genera are Lepidodendron and Sigillaria, which were tree lycophytes, and Protolepidodendron, a herbaceous Lycopodium-like plant.
We examined variability in species richness and composition of the herbaceous layer in 229 plots located in 23 forest fragments (0.1 to 255 ha), in a representative upland agricultural landscape in central Bohemia, in relation to the most important site environmental factors, edge effects, and site history.
The objective of this paper is to study the natural background soil WR in Mediterranean soils from south-western Spain under three representative forest types (pines, eucalypts and holm oaks) and its relation with plant cover (trees, shrubs and herbaceous plants) and soil properties.
In most comparative genomic analysis, three representative lineages of flowering plant species are incorporated in most analysis: Arabidopsis (a model plant for annual herbaceous dicots), grape (one model plant for perennial dicots) and Oryza sativa (a model plant for monocots).
