this study was conducted to determine the effects of arbuscular mycorrhizal fungi (glomus mosseae and glomus intraradices) symbiosis on mineral uptake of two pistachio cultivars (pistacia vera cv. qazvini and pistacia vera cv. badami-riz-zarand) grown in the greenhouse under different drought stress levels. drought stress (ds) reduced the mycorrhizal colonization in both cultivars as well as nu...

We examine the convective stability of hydrodynamic discs with full stratification in the local approximation and in the presence of thermal diffusion (or relaxation). Various branches of the relevant axisymmetric dispersion relation derived by Urpin are discussed. We find that when the vertical Richardson number is larger than or equal to the radial one (i.e. |Riz| ≥ |Rix|) and wavenumbers are...

RIZ (retinoblastoma protein-interacting zinc finger protein), also denoted PRDM2, is a transcriptional regulator and tumor suppressor. It was initially identified because of its ability to interact with another well-established tumor suppressor, the retinoblastoma protein (Rb). A short motif, IRCDE, in the acidic region (AR) of RIZ was reported to play an important role in the interaction with ...

The distal portion of chromosome 1p is one of the most commonly affected regions in human cancer. In this study of hereditary and sporadic colorectal cancer, a region of frequent deletion was identified at 32.2 centimorgans from 1ptel. Deletion breakpoints clustered in the vicinity of or inside the gene RIZ, which encodes a retinoblastoma protein-interacting zinc finger protein. Sequence analys...

The PR domain is a newly recognized protein motif that characterizes a subfamily of Krüppel-like zinc finger genes. Members of the PR domain family have been shown to play important roles in cell differentiation and malignant transformation. The RIZ gene is the founding member of this family; it was isolated because its gene products can bind to the retinoblastoma tumor suppressor protein. Here...

How can we help poor people to earn more from their knowledge rather than from their sweat and muscle? This paper summarizes a collection of essays that investigate the promotion of “poor people’s knowledge”—promoting the innovation, knowledge, and creative skills of poor people in poor countries, and particularly improving the earnings of poor people from such knowledge and skills. The collect...

This paper uses a new dataset, “WATSAN,” of Private Sector Participation (PSP) projects for water and sanitation in developing countries to examine the determinants of the number of projects signed per country between 1990 and 2004. The new dataset improves on existing sources in particular in its coverage of projects with local investors and provides adequate data for crosscountry regression a...

Is a pro-growth strategy always the best pro-poor strategy? To address this issue, this paper provides an empirical evaluation of the impact of a series of pro-growth policies on inequality and headcount poverty. We rely on a large macroeconomic data set and estimate dynamic panel models that allow us to differentiate between the shortand longrun impacts of the policies under consideration on g...
