Rhodopseudomonas palustris assimilates CO2 by the Calvin-Benson-Bassham (CBB) reductive pentose phosphate pathway. Most genes required for a functional CBB pathway are clustered into the cbbI and cbbII operons, with the cbbI operon subject to control by a LysR transcriptional activator, CbbR, encoded by cbbR, which is divergently transcribed from the cbbLS genes (encoding form I RubisCO) of the...

The ctpA (ccoI) gene product, a putative inner membrane copper-translocating P1B-type ATPase present in many bacteria, has been shown to be involved only in the cbb(3) assembly in Rhodobacter capsulatus and Bradyrhizobium japonicum. ctpA was disrupted in Rubrivivax gelatinosus, and the mutants showed a drastic decrease in both cbb(3) and caa(3) oxidase activities. Inactivation of ctpA results a...

Xanthomonas axonopodis pv. manihotis (Xam) is the causative agent of cassava bacterial blight (CBB), a worldwide disease that is particularly destructive in South America and Africa. CBB is controlled essentially through the use of resistant varieties. To develop an appropriate disease management strategy, the genetic diversity of the pathogen's populations must be assessed. Until now, the gene...

Cotton bacterial blight (CBB), an important disease of (Gossypium hirsutum) in the early 20th century, had been controlled by resistant germplasm for over half a century. Recently, CBB re-emerged as an agronomic problem in the United States. Here, we report analysis of cotton variety planting statistics that indicate a steady increase in the percentage of susceptible cotton varieties grown each...

Recently, a number of experiments have emphasized the degree to which subjects fail to detect large changes in visual scenes. This finding, referred to as ‘‘change blindness,’’ is often considered surprising because many people have the intuition that such changes should be easy to detect. Levin, Momen, Drivdahl, and Simons (2000) documented this intuition by showing that the majority of subjec...

In this study, based on colony morphology characteristics, a total of 19 fungal endophytes were isolated from root of Calotropis Procera a traditional Indian medicinal plant. All fungal isolates were screened for their dye degradation ability. The dyes used as test dyes were Rose Bengal (RB), azo dye Methyl Red (MR), Coomassie Brilliant Blue (CBB) and Methylene Blue (MB) and the concentration o...

In a ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO)-deficient mutant of Rhodobacter sphaeroides, strain 16PHC, nitrogenase activity was derepressed in the presence of ammonia under photoheterotrophic growth conditions. Previous studies also showed that reintroduction of a functional RubisCO and Calvin-Benson-Bassham (CBB) pathway suppressed the deregulation of nitrogenase synthesis i...

This paper describes two applications of the tandem scanning reflected-light microscope (TSM) for the observation of the structure of individual cells growing in tissue culture. First, the TSM is used as an alternative to interference reflection microscopy (IRM) or total internal reflection aqueous fluorescence microscopy (TIRAF) to observe cell-substratum adhesions in unstained living cells gr...

Background/aim: The aim of this study is to determine the value questions asked in routine follow-up, cord blood bilirubin (CBB) and bilirubin/albumin (B/A) ratio estimating risk developing hyperbilirubinemia. Materials methods: Term healthy 217 newborns whose CBB albumin could be obtained needed measured level at 24th 72nd hours life were included. Nutrition, sex nationality, consanguinity bet...

The objective of this study is to investigate the high-cycle fatigue (HCF) behavior carbide-bearing bainite (CBB) and carbide-free (CFB) fabricated at different transformation temperatures. limit each material determined via staircase method using a 1 kHz resonant testing machine. A new load increase test proposed as an efficient alternative estimate in HCF regimes. assessment accompanied by da...
