Influence of arbuscular mycorrhizal fungi (AMF) (Glomus etunicatum, G. intraradices and Glomus versiforme) and external phosphorus supplement (8 and 35 mg P Kg-1 soil) on leaf P, Zn, Cu and Fe nutrition of 4-month-old tea(Camellia sinensis) was studied in an glass house pot experiment. The highest leaf P concentration (up to 59.43% increase) was found in G. versiforme inoculated seedlings gro...

Pines responded to inoculation with Bursaphelenchus xylophilus by changes in reducing and nonreducing carbohydrate concentrations dependent on the pine species and the pathotype of B. xylophilus with which the trees were inoculated. Carbohydrate concentrations, in compatible pine-nematode pathotype combinations, decreased initially after inoculation and then increased slightly before decreasing...

Sigmodon hispidus (cotton rat) was previously found to have antibodies against Vesicular Stomatitis Virus, New Jersey serotype (VSV-NJ) under field conditions in Costa Rica. In order to evaluate their response to the virus and potential role as reservoirs, a total of 30 adult laboratory-raised cotton rats were experimentally inoculated with 107 TCID50/ml VSV-NJ, Greentree strain, as follows: 10...

The objective of this paper was to study the effects of two strains of isolated plant growth-promoting rhizobacteria (PGPR) on physiological and biochemical changes of wheat leaves under salinity conditions. The sterilized seeds were soaked in distilled water (control) and Nutrient Broth liquid medium of Enterobacter cloacae and Bacillus cereus (inoculated treatment) for 2 hours. After 10 days ...

BACKGROUND Positive feedback is a common motif in gene regulatory networks. It can be used in synthetic networks as an amplifier to increase the level of gene expression, as well as a nonlinear module to create bistable gene networks that display hysteresis in response to a given stimulus. Using a synthetic positive feedback-based tetracycline sensor in E. coli, we show that the population dyna...

The effects of mycorrhizal inoculation and increasing soil P levels on the expression of total proteins and peroxidase activity on passion fruit roots were evaluated. The experimental design was entirely at random, with four treatments of inoculation (a--control; b--Gigaspora albida; c--Scutellospora heterogama; d--mixture of G. albida, G. margarita, S. heterogama, and Glomus clarum) x three le...

Non-generic feedback refers to a specific event and implies that performance is malleable, while generic feedback implies that task performance reflects an inherent ability. The present study examined the influences of generic versus non-generic feedback on motor performance and learning in 10-year-old children. In the first experiment, using soccer ball kicking at a target as a task, providing...

Although many attempts have been made to inoculate successfully ,the lower animals with portions of tumors from human beings they 'have in the great majority of cases been without results. In some instances the observers have claimed that they have been successful }rot their statements are, as a rule, not convincing. Carl Lewin 1 discusses this question of transplantation at length and reviews ...
