The number of nodules that form in a legume when interacting with compatible rhizobia is regulated by the plant. We report the identification of a mutant in nodule regulation in Medicago truncatula, like sunn supernodulator (lss), which displays shoot-controlled supernodulation and short roots, similar to sunn mutants. In contrast with the sunn-1 mutant, nodulation in the lss mutant is more ext...

sunn pest, eurygaster integriceps put., is the most important pest of wheat and barley in most producing regions of iran, including lorestan province. spatial distribution and fixed precision sequential sampling plans of sunn pest by the use of two quadrate sizes 0.25 and 0.5 m2 were investigated in rainfed wheat fields in borujerd during 2004 and 2005. based on r square of regression, taylor&a...

the objective of this experiment was to investigate inheritance and gene action for resistance to sunn pest (eurygaster integriceps) and related traits in bread wheat including f1, f2 and backcross generations derived from a cross between line 15 as resistance and line 12 as susceptible parents. parents along with f1, f2, bc1 and bc2 generations were evaluated in a randomized complete block des...

Regular meiotic chromosome segregation requires sister centromeres to mono-orient (orient to the same pole) during the first meiotic division (meiosis I) when homologous chromosomes segregate, and to bi-orient (orient to opposite poles) during the second meiotic division (meiosis II) when sister chromatids segregate. Both orientation patterns require cohesion between sister centromeres, which i...

sunn pest (eurygaster integriceps put.) cause serious economic damage to wheat and barley in borujerd, north of lorestan province, iran. sweep net sampling, is the most convenient sampling procedure for many arthropods, but it is difficult to interpret in terms of accuracy and precision. much of the variation of sweep net catches, stems from human factors and its calibration. in this research, ...
