The lion's share of bacteria in various environments cannot be cloned in the laboratory and thus cannot be sequenced using existing technologies. A major goal of single-cell genomics is to complement gene-centric metagenomic data with whole-genome assemblies of uncultivated organisms. Assembly of single-cell data is challenging because of highly non-uniform read coverage as well as elevated levels of sequencing errors and chimeric reads. We describe SPAdes, a new assembler for both single-cell and standard (multicell) assembly, and demonstrate that it improves on the recently released E+V-SC assembler (specialized for single-cell data) and on popular assemblers Velvet and SoapDeNovo (for multicell data). SPAdes generates single-cell assemblies, providing information about genomes of uncultivatable bacteria that vastly exceeds what may be obtained via traditional metagenomics studies. SPAdes is available online ( http://bioinf.spbau.ru/spades ). It is distributed as open source software.

All plants are inhabited internally by diverse microbial communities comprising bacterial, archaeal, fungal, and protistic taxa. These microorganisms showing endophytic lifestyles play crucial roles in plant development, growth, fitness, and diversification. The increasing awareness of and information on endophytes provide insight into the complexity of the plant microbiome. The nature of plant-endophyte interactions ranges from mutualism to pathogenicity. This depends on a set of abiotic and biotic factors, including the genotypes of plants and microbes, environmental conditions, and the dynamic network of interactions within the plant biome. In this review, we address the concept of endophytism, considering the latest insights into evolution, plant ecosystem functioning, and multipartite interactions.

The Hidden World within Plants: Ecological and Evolutionary Considerations for Defining Functioning of Microbial Endophytes

Salinity is a major abiotic stress limiting growth and productivity of plants in many areas of the world due to increasing use of poor quality of water for irrigation and soil salinization. Plant adaptation or tolerance to salinity stress involves complex physiological traits, metabolic pathways, and molecular or gene networks. A comprehensive understanding on how plants respond to salinity stress at different levels and an integrated approach of combining molecular tools with physiological and biochemical techniques are imperative for the development of salt-tolerant varieties of plants in salt-affected areas. Recent research has identified various adaptive responses to salinity stress at molecular, cellular, metabolic, and physiological levels, although mechanisms underlying salinity tolerance are far from being completely understood. This paper provides a comprehensive review of major research advances on biochemical, physiological, and molecular mechanisms regulating plant adaptation and tolerance to salinity stress.

Effect of Plant derived Smoke on Germination, Seedling growth and Isoflavone Content of Soybean

Most Boswellia species are very important and rare, and a very small number of nurseries offer seeds and propagated plants for some Boswellia species. The present chapter reveals the environmental conditions and appropriate methods for Boswellia species propagation. Various Boswellia species grow under different environmental conditions. For example, some species can grow in the humid tropics and some grow in dry tropical regions; therefore, the soil medium can be different for these species. Similarly, the amount of water required for Boswellia growth varies from environment to environment and from season to season. For Boswellia plants, a basic vigorous growth fertilizer with balanced NPK and chelated metals are sufficient. Furthermore, clonal propagation using tissue culture techniques provides a substitute for the vegetative practices used in the past. This approach has the potential to provide a higher multiplication of uniform genotypes in a short time and provides a substitute for the species that are difficult to grow. In some Boswellia species, the rooting of stem cuttings was found to be a very easy, inexpensive and successful strategy for mass multiplication. Mostly, Boswellia seedlings grown in nurseries have reportedly grown poorly in the field. However, vegetative propagation through root cuttings is predicted to give good results in the field. In vitro techniques are used for the conservation of Boswellia species, as already reported by various researchers. Furthermore, a number of hormonal combinations were checked on various Boswellia species such as B. serrata, and some combinations were found to be successful for a few months.

Genome-wide analysis revealed novel molecular features and evolution of Anti-codons in cyanobacterial tRNAs.

Boswellia sacra has been studied with attention to the rhizosphere microbiota in its root zone. The current chapter discusses the bacterial and fungal rhizosphere communities living with both cultivated and wild B. sacra tree populations studied using next-generation sequencing approaches. The results revealed that Ascomycota and Basidiomycota were abundant in wild and cultivated populations, respectively. Furthermore, Actinobacteria were abundant in wild populations, and Proteobacteria and Acidobacteria were abundant in cultivated populations. Higher quantities of glucosidases, cellulases and IAA were found in cultivated than in wild tree rhizospheres.

extract. Results: The mortality of aqueous extract was 46.7%, methanol extract was 46.7%, ethanolic extract was 50.0%, ethyl acetate was 26.7%, acetone extract was 33.3%, chloroform extract was 40.0% and n-hexane extract was 33.3%. The lowest LD50 was found in methanol extracts (1 199.97 µg/mL). Brine shrimp cytotoxicity of tested extracts of H. rhamnoides showed that mortality rate was concentration dependent. Conclusions: It is concluded that bioactive components are present in all leaves extracts of H. rhamnoides, which could be accounted for its pharmacological effects. Thus, the results support the uses of this plant species in traditional medicine.
