TL;DR: Detailed characterization of extra sporogenous cells (exs) is reported, a male sterile mutant that generates extra meiocytes but lacks tapetal and middle cell layers in the anther and in developing seeds, suggesting that signaling through the EXS receptor kinase is a feature of a number of regulatory pathways in Arabidopsis.

TL;DR: Examination of the complement of ORFs encoding virulence, fitness, and survival factors revealed a substantial, but not complete, overlap between these two pathovars.
Abstract: Pseudomonas syringae pv. phaseolicola, a gram-negative bacterial plant pathogen, is the causal agent of halo blight of bean. In this study, we report on the genome sequence of P. syringae pv. phaseolicola isolate 1448A, which encodes 5,353 open reading frames (ORFs) on one circular chromosome (5,928,787 bp) and two plasmids (131,950 bp and 51,711 bp). Comparative analyses with a phylogenetically divergent pathovar, P. syringae pv. tomato DC3000, revealed a strong degree of conservation at the gene and genome levels. In total, 4,133 ORFs were identified as putative orthologs in these two pathovars using a reciprocal best-hit method, with 3,941 ORFs present in conserved, syntenic blocks. Although these two pathovars are highly similar at the physiological level, they have distinct host ranges; 1448A causes disease in beans, and DC3000 is pathogenic on tomato and Arabidopsis. Examination of the complement of ORFs encoding virulence, fitness, and survival factors revealed a substantial, but not complete, overlap between these two pathovars. Another distinguishing feature between the two pathovars is their distinctive sets of transposable elements. With access to a fifth complete pseudomonad genome sequence, we were able to identify 3,567 ORFs that likely comprise the core Pseudomonas genome and 365 ORFs that are P. syringae specific.

TL;DR: In this paper, the extent of SME involvement in a wide range of environmental management practices and the differences between small and medium-sized businesses were explored, and they also explored SME perceptions of pressures for, and benefits of, engagement with environmental issues.
Abstract: Environmental management represents a significant challenge for small businesses, and prior research has shown that they are typically less engaged with environmental issues than their larger counterparts. At the same time, prior research has seldom explored engagement among small and medium-sized companies (SMEs) with the wide variety of practices that are encompassed by environmental management, nor has it sought to explore heterogeneity among SMEs. In this study, we analyse the extent of SME involvement in a wide range of environmental management practices and the differences between small and medium-sized businesses. We also explore SME perceptions of pressures for, and benefits of, engagement with environmental issues. Our findings show that most small businesses are engaged in some environmental initiatives but that there is significant heterogeneity in the engagement of small and medium-sized businesses. Consistent with this, we show that the smallest companies perceive significantly fewer benefits of engagement with environmental issues. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment.

01 Nov 2008TL;DR: In this article, the authors describe the approach to developing transition pathways for a low carbon electricity system in the UK, being pursued in a major new research project, which aims to learn from past transitions to help explore future transitions and what might enable or avoid them.
Abstract: This paper describes the approach to developing transition pathways for a low carbon electricity system in the UK, being pursued in a major new research project The project aims (a) to learn from past transitions to help explore future transitions and what might enable or avoid them; (b) to design and evaluate transition pathways towards alternative socio-technical energy systems and infrastructures for a low carbon future; and (c) to understand and where appropriate model the changing roles, influences and opportunities of large and small 'actors' in the dynamics of transitions The paper describes the approach being taken, which builds on the work of Dutch researchers on transitions and transition management using a multi-level framework of niches, socio-technical regime and landscape It also outlines its application to the case of transition pathways to a regime dominated by local distributed electricity generation, including the evolution of the physical and institutional infrastructure changes, and the roles of actors, both large, eg multinational energy supply and distribution companies, national governments, major investors, and small, eg households, innovators and entrepreneurs

TL;DR: The results describe the first demonstration of tunable intrinsic electrical conductivity in this class of materials and serve as a blueprint for controlling charge transport in MOFs with π-stacked motifs.
Abstract: Isostructural metal–organic frameworks (MOFs) M2(TTFTB) (M = Mn, Co, Zn, and Cd; H4TTFTB = tetrathiafulvalene tetrabenzoate) exhibit a striking correlation between their single-crystal conductivities and the shortest S···S interaction defined by neighboring TTF cores, which inversely correlates with the ionic radius of the metal ions. The larger cations cause a pinching of the S···S contact, which is responsible for better orbital overlap between pz orbitals on neighboring S and C atoms. Density functional theory calculations show that these orbitals are critically involved in the valence band of these materials, such that modulation of the S···S distance has an important effect on band dispersion and, implicitly, on the conductivity. The Cd analogue, with the largest cation and shortest S···S contact, shows the largest electrical conductivity, σ = 2.86 (±0.53) × 10–4 S/cm, which is also among the highest in microporous MOFs. These results describe the first demonstration of tunable intrinsic electrical c...
