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.

Mechanism of Salinity Tolerance in Plants: Physiological, Biochemical, and Molecular Characterization

Boswellia sacra (Burseraceae), a keystone endemic species, is famous for producing a fragrant oleogum resin. However, its genetic make-up, especially its chloroplast genome information, is still unknown. Here, we described the chloroplast (cp) genome of B. sacra for the first time. The complete cp sequence revealed a circular genome of 160,543 bp with a 37.61% GC content. The cp genome is a typical quadripartite chloroplast structure with inverted repeats (IRs 26,763 bp) separated by small single copy (SSC; 18,962 bp) and large single copy (LSC; 88,055 bp) regions. De novo assembly and annotation showed the presence of 114 unique genes with 83 protein-coding regions. A phylogenetic analysis revealed that the B. sacra cp genome is closely related to the cp genomes of Azadirachta indica and Citrus sinensis, while most of the syntenic differences were found in the non-coding regions. The pairwise distance among 76 shared genes in B. sacra and A. indica was highest for atpA, rpl2, rps12 and ycf1. The cp genome of B. sacra reveals a novel genome, which could be used for further studies to understand its diversity, taxonomy and phylogeny.

The results of this study revealed a high level of genetic differentiation within populations and a low level of genetic diversity among populations of B. sacra. AFLP and SSR markers revealed more variations compared to RAPD and SDS-PAGE markers. Overall, a reasonable level of genetic diversity is observed in all the populations, but some populations showed high levels of genetic variations and high genetic and geographic distances (Thumrait, Dowkha and Mughsil). Our findings may be useful for further molecular study of and conservation strategies for this endemic species.

Introduction: Vitiligo is a specific, common, often heritable acquired disorder characterized by well-circumscribed milky white cutaneous macules and patches devoid of identifiable melanocyte. Treatment of vitiligo, though quite frustrating, includes repigmentation therapies like Topical glucocorticoids, Topical calcipotrieinene, Topical PUVA (Psoralen + Ultraviolet Light A). The combination of calcipotriol and PUVA proves quite effective for management of this condition.
Objectives: To compare the effectiveness of PUVA and the combination of topical calcipotriol and PUVA in treatment of vitiligo.
Materials and Methods: This quasi experimental study was undertaken at Combined Military Hospital, Dhaka Cantonment, Dhaka from March to October 2015. A total of 32 patients suffering from vitiligo diagnosed clinically and confirmed by Wood’s lamp examination were selected as study population. Systemic PUVA, thrice weekly was given but Topical calcipotriol applied twice daily at one side of the body and other side used nothing Topically. Response was assessed clinically every 4 weeks along with photographic record and compared between two sides of the body.
Results: During the course of the treatment, the calcipotriol plus PUVA treated side showed considerably better improvement than only PUVA treated side. The response was Excellent; 37.8% (12/32), Good; 31.3% (10/32), Fair; 18.8% (6/32), Poor; 12.5% (4/32) in calcipotriol plus PUVA treated side whereas Excellent; 12.5% (4/32), Good; 25% (8/32), Fair; 43.8% (14/32) and Poor; 18.8% (6/32) in only PUVA treated side.
Conclusion: This study shown that concurrent topical calcipotriol potentiates the efficacy of PUVA in the treatment of vitiligo along with the fact that this combination achieves earlier pigmentation with a lower total UVA dosage in comparison to only PUVA therapy.

Role of Topical Calcipotriol to Potentiate the Effect of Photochemotherapy (PUVA) in Treatment of Vitiligo

One new cyclopropyl-triterpenoid (1), along with four known constituents including octacosan-1-ol (2), pentacosanoic acid (3), β-sitosterol (4), and β-sitosterol 3-O-β-D-glucopyranoside (5) were isolated from the aerial parts of Ochradenus arabicus for the first time. These compounds were isolated by repeated column chromatography followed by further purification through recycling HPLC. The structure of the new secondary metabolite 1 was established on the basis of UV, IR, 1D- (1H- and 13C-) and 2D-NMR (HMBC and HSQC), and MS spectral data. The molecular mass was determined by HR-MS, and hence the molecular formula was deduced. The configurations of stereogenic centers in the molecule were assigned by NOESY experiments, along with biogenetic considerations. The structures of the known compounds were confirmed by comparison of their physical and spectroscopic data with those reported in literature.
