Although significant intraindividual differences in self-reported diurnal preference, as measured by validated questionnaires, exist, the relative contribution of exogenous and endogenous factors to self-reported diurnal preference largely remains to be investigated. The present study examined which items from the Horne-Östberg (HÖ) questionnaire of diurnal preference were better at predicting ...

Phosphate (Pi) deficiency severely affects crop yield. Modern high yielding rice genotypes are sensitive to Pi deficiency whereas traditional rice genotypes are naturally compatible with low Pi ecosystems. However, the underlying molecular mechanisms for low Pi tolerance in traditional genotypes remain largely elusive. To delineate the molecular mechanisms for low Pi tolerance, two contrasting ...

Abstract Salinization of agricultural lands, particularly rice paddies, results in the drastic decline crop yields. Soil salinization impacts plant physiology by inducing salt stress which may leads to osmotic stress, ionic and water-related nutrient imbalance. These imbalances necessitate need for plants produce osmolytes including proline glycine betaine. This study aimed elucidate dynamic ch...

The flowering plant Solanum chacoense uses an S-RNase-based self-incompatibility system in order to reject pollen that shares the same genes at the S-locus (S-haplotype) with the style (an incompatible reaction). Two different models have been advanced to explain how compatible pollen tubes are protected from the cytotoxic effects of the S-RNase, sequestration of the S-RNase in a vacuolar compa...

BACKGROUND In some populations, complete shifts in the genotype of the strain of measles circulating in the population have been observed, with given genotypes being replaced by new genotypes. Studies have postulated that such shifts may be attributable to differences between the fitness of the new and the old genotypes. METHODS We developed a stochastic model of the transmission dynamics of ...

Tomato genotypes ( Solanum spp.) have genetic variability of most desirable features, such as resistance to biotic and abiotic stresses. However, incompatibility crosses wild with domesticated tomatoes, or even between genotypes, hinders the breeding process. Thus, knowledge reproductive biology conditions is necessary maximize success artificial crossings. This study evaluated compatibility se...

In four experiments, we show that goals associated with approach and avoidance needs influence persuasion and that the accessibility of distinct self-views moderates these effects. Specifically, individuals with an accessible independent selfview are more persuaded by promotion-focused information that is consistent with an approach goal. In contrast, individuals whose interdependent self-view ...

Amoebae of the Myxomycete Physarum polycephalum differentiate to yield plasmodia in two ways: in crossing, haploid amoebae of appropriate genotypes fuse to form diploid plasmodia; in selfing, plasmodia form without amoebal fusion or increase in ploidy. Amoebae carrying the mating-type allele matAh (formerly mt(h)) self efficiently, but occasionally give rise to mutants that self at very low fre...
