INTRODUCTION: IN PURSUIT OF MY PASSION he mystery of life's origin intrigues many people, including me. T Graduate courses helped me develop a strong appreciation for life's chemistry when I was in the doctoral program at Ohio University during the mid-1980s. Like a hungry man with a stack of pancakes set in front of him, I devoured books and journal articles that weren't even required reading. I wanted to know how life originated. How could the chemical systems that carry out life's fundamental processes come into existence? How did biochemistry begin? Though not part of my formal course work, these questions motivated me to look for answers at every opportunity. Origin-of-life researchers explained that complex chemical mixtures on early Earth organized themselves into the first living entities in a grad­ ual stepwise fashion. But to me, this process of chemical evolution seemed unconvincing and inadequate to produce the cell's vastly complex, highly sophisticated, and tightly orchestrated molecular systems. Based on my training, I knew that chemical systems could self-organize, but the organ­ ization displayed by biochemical systems differs qualitatively from the regular and repetitive order possessed by crystals and other types of molecular aggregates that form spontaneously. The best scientists typically experience difficulty getting a few chem­ icals in a flask to do what they want, even when they expend enormous effort and rely on the past work of others. Whenever I worked through the evolutionary pathways suggested by origin-of-life researchers, I always came back to the same question: How could random physical and chem­ ical events yield the amazingly elegant, highly integrated biochemical sys­ tems found inside living cells? I could envision realistic chemical pathways that on occasion, by chance, could yield molecules with useful properties for living systems. But isolated chemicals don't constitute life. Numerous complex molecules- q Origins of Life each carrying out a specific but limited function-work in concert to form biochemical systems. In turn, numerous biochemical systems interact in an orchestrated fashion to support the activities of even the simplest cells. A molecule's function contributes to life processes only in the con­ text of the entire ensemble of systems. In other words, for life to emerge, its biochemical systems must come into existence all at once, not step by step.

Lithology 1 is composed of coarse-grained olivines enclosed inpoikilitic pigeonites, resembling lherzolitic shergottites. Lithology 2 is finer-grained and composed of olivine phenocrysts set within a groundmass of augite, olivine, plagioclase (shocked to maskelynite) and accessory phases such as Ca-phosphates, representing an olivine-phyric shergottite. Lithology 1 may be an early-formed cumulate while Lithology 2 may represent a cooled liquid laden with accumulated olivine crystals.

This article is published with open access Abstract Our current knowledge of host–virus interactions in biofilms is limited to computational predictions based on laboratory experiments with a small number of cultured bacteria. However, natural biofilms are diverse and chiefly composed of uncultured bacteria and archaea with no viral infection patterns and lifestyle predictions described to date. Herein, we predict the first DNA sequence-based host–virus interactions in a natural biofilm. Using single-cell genomics and metagenomics – 1234567890();,: 1234567890();,: applied to a hot spring mat of the Cone Pool in Mono County, California, we provide insights into virus host range, lifestyle and distribution across different mat layers. Thirty-four out of 130 single cells contained at least one viral contig (26%), which, together with the metagenome-assembled genomes, resulted in detection of 59 viruses linked to 34 host species.

  • The Positive Role of the Ecological Community in the Genomic Revolution
    The positive role of the ecological community in the genomic revolution Dawn Field, Barbara Methe, Karen Nelson, and Nikos Kyrpides, An increasing number of ecologists are turning to the use of genomic technologies to complement and extend traditional methods of characterizing microbial diversity and its biological consequences (Xu, 2006). The SCOPE meeting on Microbial Environmental Genomics (MicroEnGen-II, Shanghai, June 12-15, 2006) provided a rich set of examples of progress at this interface (van Veen, Kowalchuk, 2006), many of which are described in this special issue. The session of this meeting entitled ‘new frontiers’ included two presentations on informatics and data management. We (DF and NK) talked about projects we are involved in, namely, the Integrated Microbial Genomes Resource (IMG) (Markowitz et al., 2006), the Genomic Standards Consortium (GSC) (Field et al., et al, in review) and the NERC Environmental Bioinformatics Centre (NEBC) (Field et al., 2005). In this commentary we briefly describe these projects, provide updated information on their development and attempt to expand on the wider issue of the increasing need for ecologists to become involved in the development of these and similar genomic resources. These projects have all benefited from the direct and indirect contribution of ecologists. Further, each is working in its own way to help strengthen the position of researchers working in eco- and environmental genomics. The IMG system is an example of a new generation database project attempting to standardize access to the publicly available collection of genomes, through a comparative genomics approach (Markowitz et al., 2006). The GSC represents an international effort to produce consensus on the ways in which we collect, exchange and represent genomic metadata (Field et al., et al, in review).

  • F. Nucleatum Sub Spp Vincentii and Its Comparison with the Genome of F
    Letter Genome Analysis of F. nucleatum sub spp vincentii and Its Comparison With the Genome of F. nucleatum ATCC 25586 Vinayak Kapatral,1 Natalia Ivanova, Iain Anderson, Gary Reznik, Anamitra Bhattacharyya, Warren L. Gardner, Natalia Mikhailova, Alla Lapidus, Niels Larsen, Mark D’Souza, Theresa Walunas, Robert Haselkorn, Ross Overbeek, and Nikos Kyrpides Integrated Genomics Inc., Chicago, Illinois 60612, USA We present the draft genome sequence and its analysis for Fusobacterium nucleatum sub spp. vincentii (FNV), and compare that genome with F. nucleatum ATCC 25586 (FN). A total of 441 FNV open reading frames (ORFs) with no orthologs in FNhave been identified. Of these, 118 ORFs have no known fun ction and are unique to FNV, whereas 323 ORFs have functional orthologs in other organisms. In addition to the excretion of butyrate, H2S and ammonia-like FN, FNV has the additional capability to excrete lactate and aminobutyrate. Unlike FN, FNV is likely to incorporate galactopyranose, galacturonate, and sialic acid into its O-antigen. It appears to transport ferrous iron by an anaerobic ferrous transporter. Genes for eukaryotic type serine/threonine kinase and phosphatase, transpeptidase E-transglycosylase Pbp1A are found in FNV but not in FN. Unique ABC transporters, cryptic phages, and three types of restriction-modification systems have been identified in FNV. ORFs for ethanolamine utilization, thermostable carboxypeptidase, ␥ glutamyl-transpeptidase, and deblocking aminopeptidases are absent from FNV. FNV, like FN, lacks the classical catalase-peroxidase system, but thioredoxin/glutaredoxin enzymes might alleviate oxidative stress. Genes for resistance to antibiotics such as acriflavin, bacitracin, bleomycin, daunorubicin, florfenicol, and other general multidrug resistance are present.

  • Paleontology1
    PALEONTOLOGY1 Thoreau’s firm grasp of paleontology laid the groundwork for the climax of WALDEN, which describes the emergence of complexity and beauty from the simple flow of muddy sand at the Deep Cut. It also was the taproot of his lifelong frustration with Christian supernaturalists, who insisted on a fairly brief history of life. Paraphrasing Lyell’s PRINCIPLES, he jested [in A WEEK ON THE C ONCORD AND M ERRIMACK R IVERS]: “It took 100 years to prove that fossils are organic, and 150 more, to prove that they are not to be referred to the Noachian deluge.” Not everyone believes this, even today. Modern “young Earth” creationists still insist that the Elizabethan-era Mosaic chronology of Archbishop Ussher is the correct one, and that we twenty-first century scientists are in error. — Professor Robert M.
