ABSTRACT We identified CENP-50 as a novel kinetochore component. We found that CENP-50 is a constitutive component of the centromere that colocalizes with CENP-A and CENP-H throughout the cell cycle in vertebrate cells. To determine the precise role of CENP-50, we examined its role in centromere function by generating a loss-of-function mutant in the chicken DT40 cell line. The CENP-50 knockout was not lethal; however, the growth rate of cells with this mutation was slower than that of wild-type cells. We observed that the time for CENP-50-deficient cells to complete mitosis was longer than that for wild-type cells. Centromeric localization of CENP-50 was abolished in both CENP-H- and CENP-I-deficient cells. Coimmunoprecipitation experiments revealed that CENP-50 interacted with the CENP-H/CENP-I complex in chicken DT40 cells. We also observed severe mitotic defects in CENP-50-deficient cells with apparent premature sister chromatid separation when the mitotic checkpoint was activated, indicating that CENP-50 is required for recovery from spindle damage.

Relating the temperature dependence of photosynthetic biomass production to underlying metabolic rates in autotrophs is crucial for predicting the effects of climatic temperature fluctuations on the carbon balance of ecosystems. We present a mathematical model that links thermal performance curves (TPCs) of photosynthesis, respiration, and carbon allocation efficiency to the exponential growth rate of a population of photosynthetic autotroph cells. Using experiments with the green alga, Chlorella vulgaris, we apply the model to show that the temperature dependence of carbon allocation efficiency is key to understanding responses of growth rates to warming at both ecological and longer-term evolutionary timescales. Finally, we assemble a dataset of multiple terrestrial and aquatic autotroph species to show that the effects of temperature-dependent carbon allocation efficiency on potential growth rate TPCs are expected to be consistent across taxa. In particular, both the thermal sensitivity and the optimal temperature of growth rates are expected to change significantly due to temperature dependence of carbon allocation efficiency alone. Our study provides a foundation for understanding how the temperature dependence of carbon allocation determines how population growth rates respond to temperature.

We present experimental data on the nematic alignment of Escherichia coli bacteria confined in a slit, with an emphasis on the effect of growth rate and corresponding changes in cell aspect ratio. Global alignment with the channel walls arises from the combination of local nematic ordering of nearby cells, induced by cell division and the elongated shape of the cells, and the preferential orientation of cells proximate to the side walls of the slit. Decreasing the growth rate leads to a decrease in alignment with the walls, which is attributed primarily to effects of changing cell aspect ratio rather than changes in the variance in cell area. Decreasing confinement also reduces the degree of alignment by a similar amount as a decrease in the growth rate, but the distribution of the degree of alignment differs. The onset of alignment with the channel walls is coincident with the slits reaching their steady-state occupancy and connected to the re-orientation of locally aligned regions with respect to the walls during density fluctuations.

Shoot cultures of <em>Gentiana punctata</em> L. were inoculated with suspension of <em>Agrobacterium rhizogenes</em> strain A4 M70GUS. Hairy roots which appeared 2-3 weeks later were cultured on hormone-free, liquid, WPM (Lloyd and McCown 1980) basal medium for more than 5 years (60 subcultures). Growth rate of transformed roots was higher than the growth rate of nontransformed roots. Spontaneous shoot regeneration occured only in three culture vessels in subcultures No. 40 and 42. Plants had phenotype characteristics typical for <em>A. rhizogenes</em> transformed plants including: wrincled leaves, short internodes, plagiotropic roots and in general their growth rate was reduced. These plants also manifested precocious formation of flower buds without vernalization and flowering under in vitro conditions. Flowers were pale yellow, the same as in the standard phenotype.

The most frequent transboundary haze in the world takes place in Southeast Asia. It is usually caused by land-use changes, open burning, peat combustion, wildfires, and other farming activities. Serious haze occurred in 1983, 1997, 2005, 2006, 2009, 2010, 2013, 2015 and 2016, originating from large-scale forest fires in western Sumatra and southern Kalimantan, Indonesia. It caused adverse effects to locals as well as neighbouring countries, affecting their health, economy, agriculture, and biodiversity. Among the serious effects of haze are increased respiratory-related mortality due to toxic airborne particles, jet crashs and ship collisions due to restricted visibility, reduction of crop growth rate due to limited solar radiation, and extinction of endangered primates due to habitat loss. Neighbouring countries like Malaysia and Singapore sometimes have to close schools to prevent people from being exposed to air pollution, and its consequent respiratory ailments.

The paper reviews the effect of nonmonetary factors on inflation dynamics in Russia from 2000 to 2018. The period under review was divided into two intervals with different economic dynamics: 2000–2008 – the period of economic growth in Russia, 2009–2018 – the period of a slower rate of economic growth. Both periods were analyzed for various nonmonetary factors having an impact on inflation, which helped reveal common as well as distinctive features of nonmonetary factors. Some factors, such as the growth rate of agricultural prices had a significant impact on the consumer price inflation dynamics over the whole period under research. Other nonmonetary factors ceased to have an effect on consumer prices making room for others. Thus, the volume of imports turned out to be significant only in the period from 2009 to 2018, which is explained by the geopolitical situation and introduced economic sanctions. The conducted research confirmed a growing role of nonmonetary factors in the inflation processes. This conclusion requires consideration of specific features of nonmonetary causes of inflation on behalf of the Central bank and the fiscal organs in development of concrete steps to reduce inflation. The priority should continue to be given to effective tariff regulation, modernization of industry and promotion of competition.

The Relationship

Pseudomonas sp. strain PCL1171 undergoes reversible colony phase variation between opaque phase I and translucent phase II colonies, which is dependent on spontaneous mutations in the regulatory genes gacA and gacS. Mutation of the mutS gene and constitutive expression of rpoS increases the frequency at which gac mutants appear 1000- and 10-fold, respectively. Experiments were designed to study the relationship between gacS, rpoS and mutS. These studies showed that (i) a functional gac system is required for the expression of rpoS, (ii) RpoS suppresses the expression of mutS and therefore increases the frequency of gac mutants, and (iii) upon mutation of rpoS and gacS, the expression of mutS is increased. Mutation of gacS abolishes suppression of mutS expression in stationary growth, suggesting that additional gac-dependent factors are involved in this suppression. In conclusion, inefficient mutation repair via MutS, of which the expression is influenced by gacA/S itself and by rpoS in combination with other factors, contributes to the high frequency of mutations accumulating in gacA/S. The role of RpoS in the growth advantage of a gac mutant was analysed, and mutation of rpoS only reduced the length of the lag phase, but did not affect the growth rate, suggesting a role for both RpoS and a reduction of metabolic load in the growth advantage of a gac mutant.
