Their expression is thus predicted to require the presence of a persistent meristematic zone 1 and/or an infection zone 2. Indeed zones 1 and 2 are smaller than zone 3 in mature nodules and absent from exoA nodules at 10 dpi.
But most of the focus in the markets has been on the lack of progress in solving persistent euro zone debt problems, which "is creating a pocket of selling with no buyers," said Alan B. Lancz, the president of Alan B. Lancz & Associates.
Only CapI-Hox3 shows persistent growth zone expression in juvenile stages.
We approximated the site as a persistent spherical zone with a non-depleting concentration of attractant.
The two species of New World jacanas maintain a narrow, and persistent hybrid zone in western Panama.
We demonstrated that jacanas maintain a narrow, and persistent hybrid zone in southwestern Panama that is coincident for three phenotypic traits, mtDNA, and one of two autosomal markers.
Our analyses of phenotypic and genetic markers of jacanas across western Panama and beyond firmly establish hybridization between the two species, and provide the first documentation of a persistent hybrid zone in a simultaneously-polyandrous bird species [ 4].
Its elongate shape records a long history of fluid lava flows not only from its summit but from its two persistent rift zones.
Numerical modeling of vapor-phase contaminant transport was used to investigate the correlation between measured vapor-phase mass discharge, MFr, from a persistent, vadose-zone contaminant source and the resulting groundwater contaminant concentrations.
However, although Creber and Ash [76] did not give detailed locality information where this horizon may be observed, Sid Ash (personal communication) has identified both the persistent orange silcrete zone at Blue Mesa and the persistent red silcrete zone above the Rainbow Forest Bed northeast of Rainbow Forest as representing this "single" horizon.
