Rootstocks are an important component for citrus adaptation to increasing biotic and abiotic stresses resulting from global climate change. There is a strong complementarity between Citrus species, which adapt stresses, Poncirus trifoliata its intergeneric hybrids, exhibit resistances or tolerances major diseases pests. Thus, symmetrical somatic hybridization complementary diploid rootstocks of...

Demonstration of genetic control over riparian tree productivity has major implications for responses of riparian systems to shifting environmental conditions and effects of genetics on ecosystems in general. We used field studies and common gardens, applying both molecular and quantitative techniques, to compare plot-level tree aboveground net primary productivity (ANPP(tree)) and individual t...

to estimate combining ability and the model of gene action for some quantitative characters, 5 different rice genotypes were used for producing a half diallel hybrids. to consider 7 quantitative traits, hybrids and their corresponding parents were evaluated based on a randomized complete block design with three replications at the rice research station of amol, iran in 2007. mean squares regard...

Intracellular recognition of non-self and also self-nucleic acids can result in the initiation of potent pro-inflammatory and antiviral cytokine responses. Most recently, cGAS was shown to be critical for the recognition of cytoplasmic dsDNA. Binding of dsDNA to cGAS results in the synthesis of cGAMP(2'-5'), which then binds to the endoplasmic reticulum resident protein STING. This initiates a ...

<p><strong>Background. </strong>The husk tomato (<em>Physalis ixocarpa</em> Brot. ex Horm.) is an obligated allogam species with gametophyte auto-incompatibility, which impedes the generation of endogamic lines by auto-fecundation to obtain hybrids. <strong>Objective.</strong> To evaluate effect six doses <sup>60</sup>Co gamma rays (from 0 3...

in order to study of some effective phenologic and physiologic characteristics on 18 sunflower hybrids yield under optimum conditions, an experiment was conducted as randomized complete block design with three replications at the research field of seed and plant improvement institute-karaj in 2006-2007. the result indicated that the hybrids showed significant difference in phonologic characteri...

the sugar beet plant has a conical-shaped root and at harvest the tap-root breaks which remains in the soil. as a result, a significant amount of root yield and consequently sugar content is lost. furthermore, the field soil remains in the root fissures and is carried with the root to sugar factory. in rhizomania and nematode-infested areas, the soil movement causes the disease wide spread. in ...

This research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. To this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. Main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

Transcriptome analysis is a powerful tool for unveiling the distribution and magnitude of genetic incompatibilities between hybridizing taxa. The nature of such incompatibilities is closely associated with the evolutionary histories of the parental species and may differ across tissues and between the sexes. In eusocial insects, the presence of castes that experience divergent selection regimes...
