An enzyme system prepared from maize chloroplasts catalyzes the synthesis of DNA from maize chloroplast DNA sequences cloned in bacterial plasmids. Cloned maize chloroplast DNA fragments Bam HI 17' (2470 bp) and Eco RI x (1368 bp) have been shown to be preferred templates for in vitro DNA synthesis catalyzed by pea chloroplast DNA polymerase preparations [Gold et al. (1987) Proc. Natl. Acad. Sc...

Despite growing interest in the environmental performance and management of public organizations, relatively little is known about the steps individual public employees are taking at their own discretion to promote environmental sustainability and environmental stewardship in the workplace. This article examines public employees’ participation in eco-helping and eco-civic engagement in the work...

Plasmids of approximately 80 kb in size are found in nearly all clinical isolates of Salmonella dublin and are believed to be essential for virulence. We have shown previously that the 80-kb plasmid pSDL2 is required for the S. dublin Lane strain to establish a lethal systemic infection in BALB/c mice after oral or intraperitoneal inoculation. We now present a physical and genetic characterizat...

Escherichia coli RNase E (Eco-RNase E), encoded by rne (Eco-rne), is considered the global RNA decay initiator. Although Eco-RNase E is an essential gene product in E. coli, some bacterial species, such as Bacillus subtilis, do not possess Eco-RNase E sequence homologues. B. subtilis instead possesses RNase J1/J2 (Bsu-RNase J1/J2) and RNase Y (Bsu-RNase Y) to execute RNA decay. Here we found th...

The major goal of ecological evolutionary developmental biology, also known as "eco-evo-devo," is to uncover the rules that underlie the interactions between an organism's environment, genes, and development and to incorporate these rules into evolutionary theory. In this chapter, we discuss some key and emerging concepts within eco-evo-devo. These concepts show that the environment is a source...

INTRODUCTION On 8 June 2017, the Supreme Court in the United Kingdom rejected a legal appeal in the high-profile case of Charlie Gard, a British infant with a severe genetic disorder whose parents had disagreed with medical professionals and were requesting treatment that the doctors believed was futile. The case was the latest in a series of UK legal cases where courts have authorized withdraw...

Environmental sustainability is an important issue for many individuals, businesses, and governments nowadays. One of the road blocks to sustainable practice is cost, which is an important consideration, particularly for business. The eco-efficiency movement was initiated to address this concern. This chapter reviews the eco-efficiency concept and explains why it is becoming a current issue for...

objective: evaluating the status of the eco member countries in relation to goal 5 of 3rd millennium which includes 75% reduction of maternal mortality rate till 2015 in comparison to 1990. material and methods: in 2009, we have critically reviewed the countries’ mdg reports and extracted the data on each mdgs’ indicator by year and cause of mortality, (if possible) resident area (urban/rural) ...
