Background and objectives: Rangeland suitability for livestock grazing is assessed by scoring criteria for vegetation, water resources and soil erosion. In this study, the suitability of Lar Absar rangeland in Mazandaran province for grazing domestic animals and herbivorous wildlife grazing was investigated. Many researchers have examined pasture suitability for grazing cattle, sheep, goats, an...
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
The molecular responses of a plant to a stress and the molecular profiles of plant organs during their development and differentiation are the reflection of the contribution from different cell types composing the plant and the organs. Hence, a major limitation to understanding plant cellular and molecular responses in different cells is the multicellular complexity of the plant or organs used ...
In plants the dorsoventral boundary of leaves defines an axis of symmetry through the centre of the organ separating the top (dorsal) and bottom (ventral) tissues. Although the positioning of this boundary is critical for leaf morphogenesis, how the boundary is established and how it influences development remains unclear. Using live-imaging and perturbation experiments we show that leaf orient...
Five organisms having completely sequenced genomes and belonging to all major branches of green plants (Viridiplantae) were analyzed with respect to their content of P-type ATPases encoding genes. These were the chlorophytes Ostreococcus tauri and Chlamydomonas reinhardtii, and the streptophytes Physcomitrella patens (a non-vascular moss), Selaginella moellendorffii (a primitive vascular plant)...
