Dune plants are subjected to disturbance and environmental stresses, but little is known about the possible combined effects of such factors on growth and spatial colonization. We investigated how clones of Sporobolusvirginicus, a widespread dune species, responded to the independent and interactive effects of breakage of rhizomes, breakage position and burial regime. Horizontal rhizomes were s...

Adjusting the thickness and internodal length of the myelin sheath is a mechanism for tuning the conduction velocity of axons to match computational needs. Interactions between oligodendrocyte precursor cells (OPCs) and developing axons regulate the formation of myelin around axons. We now show, using organotypic cerebral cortex slices from mice expressing eGFP in Sox10-positive oligodendrocyte...

a plant is vegetatively reproduced, or cloned, so that the same genotype can I;evelop in more than one environment, differences in a given character between the individuals of the clone reflect the effect of the different environments on the expression of the character. If a population of plants is cloned and randomly grown in a nonuniform environment, it is possible to estimate environmental a...

in order to evaluate the genetic diversity and identify quantitative trait loci(qtl) controlling agro-morphological triats such as leaf length, leaf width, leaf number, internode distance, dried leaf yield per plot, plant height and stem girth, the genetic population including 225 f 2:3 families from the cross between two oriental-type tobacco genotypes ‘spt 406 (paternal) × basma seres 31 (mat...

some research indicates that n2 fixation in soybean cannot provide adequate nitrogen for proper yield. therefore, the effect of nitrogen and bradyrhizobium japonicum bacteria on some agronomic characteristics and quality of soybean cultivars was examined based on split plot in a randomized complete blocks design with three replications in 2012 at kerman township. treatments including control (w...

TCP transcription factors constitute a small family of plant-specific bHLH-containing, DNA-binding proteins that have been implicated in the control of cell proliferation in plants. Despite the significant role that is likely to be played by genes that control cell division in the elaboration of plant architecture, functional analysis of this family by forward and reverse genetics has been hamp...

Biophysical parameters related to gibberellin (GA)-dependent stem elongation were examined in dark-grown stem-length genotypes of Pisum sativum L. The rate of internode expansion in these genotypes is altered due to recessive mutations which affect either the endogenous levels of, or response to, GA. The GA deficient dwarf L181 (ls), two GA insensitive semierectoides dwarfs NGB5865 and NGB58...
