1Comparison of a plant based natural surfactant with SDS for washing of As(V) from Fe rich soil显示文摘This study explores the possible application of a biodegradable plant based surfactant,obtained from Sapindus mukorossi,for washing low levels of arsenic(As)from an iron(Fe)rich soil.Natural association of As(V)with Fe(III)makes the process difcult.Soapnut solution was compared to anionic surfactant sodium dodecyl sulfate(SDS)in down-flow and a newly introduced suction mode for soil column washing.It was observed that soapnut attained up to 86%efciency with respect to SDS in removing As.Full factorial design of experiment revealed a very good fit of data.The suction mode generated up to 83 kPa pressure inside column whilst down-flow mode generated a much higher pressure of 214 kPa,thus making the suction mode more efcient.Micellar solubilisation was found to be responsible for As desorption from the soil and it followed 1st order kinetics.Desorption rate coefcient of suction mode was found to be in the range of 0.005 to 0.01,much higher than down-flow mode values.Analysis of the FT-IR data suggested that the soapnut solution did not interact chemically with As,ofering an option for reusing the surfactant.Soapnut can be considered as a soil washing agent for removing As even from soil with high Fe content.Soumyadeep Mukhopadhyay Mohd.

2Development of a panel of unigene-derived polymorphic EST–SSR markers in lentil using public database information显示文摘Lentil(Lens culinaris Medik.), a diploid(2n = 14) with a genome size greater than 4000 Mbp, is an important cool season food legume grown worldwide. The availability of genomic resources is limited in this crop species. The objective of this study was to develop polymorphic markers in lentil using publicly available curated expressed sequence tag information(ESTs). In this study, 9513 ESTs were downloaded from the National Center for Biotechnology Information(NCBI) database to develop unigene-based simple sequence repeat(SSR) markers. The ESTs were assembled into 4053 unigenes and then analyzed to identify 374 SSRs using the MISA microsatellite identification tool. Among the 374 SSRs, 26 compound SSRs were observed.Primer pairs for these SSRs were designed using Primer3 version 1.14. To classify the functional annotation of ESTs and EST–SSRs, BLASTx searches(using E-value 1 × 10-5) against the public UniP rot(http://gffzzc0d2db89b939488bhp60xqp5ncouc65uc.ffgz.tsg.suse.edu.cn/) and NCBI(http://gffzz5b533c64939a43b3hp60xqp5ncouc65uc.ffgz.tsg.suse.edu.cn/) databases were performed. Further functional annotation was performed using PLAZA(version3.0) comparative genomics and GO annotation was summarized using the Plant GO slim category. Among the synthesized 312 primers, 219 successfully amplified Lens DNA. A diverse panel of 24 Lens genotypes was used to identify polymorphic markers. A polymorphic set of 57 markers successfully discriminated the test genotypes. This set of polymorphic markers with functional annotation data could be used as molecular tools in lentil breeding.Debjyoti Sen Gupta Peng Cheng Gaurav Sablok Dil Thavarajah Pushparajah Thavarajah Clarice J.Coyne Shiv Kumar Michael Baum Rebecca J.McGee 2016The Crop Journal2016,4,5:2

5A comparative study of biopolymers and alum in the separation and recovery of pulp fibres from paper mill effluent by flocculation显示文摘Recovery of cellulose fibres from paper mill effluent has been studied using common polysaccharides or biopolymers such as Guar gum,Xanthan gum and Locust bean gum as flocculent.Guar gum is commonly used in sizing paper and routinely used in paper making.The results have been compared with the performance of alum,which is a common coagulant and a key ingredient of the paper industry.Guar gum recovered about 3.86 mg/L of fibre and was most effective among the biopolymers.Settling velocity distribution curves demonstrated that Guar gum was able to settle the fibres faster than the other biopolymers;however,alum displayed the highest particle removal rate than all the biopolymers at any of the settling velocities.Alum,Guar gum,Xanthan gum and Locust bean gum removed 97.46%,94.68%,92.39%and 92.46%turbidity of raw effluent at a settling velocity of 0.5 cm/min,respectively.The conditions for obtaining the lowest sludge volume index such as pH,dose and mixing speed were optimised for guar gum which was the most effective among the biopolymers.Response surface methodology was used to design all experiments,and an optimum operational setting was proposed.The test results indicate similar performance of alum and Guar gum in terms of floc settling velocities and sludge volume index.Since Guar gum is a plant derived natural substance,it is environmentally benign and offers a green treatment option to the paper mills for pulp recycling.Sumona Mukherjee Soumyadeep Mukhopadhyay Agamuthu Pariatamby Mohd.

6Population structure analysis and determination of neurotoxin content in a set of grass pea (Lathyrus sativus L.) accessions of Bangladesh origin显示文摘Grass pea(Lathyrus sativus L.) is a crop that is considered one of the more resilient to climate change. With protein-rich seeds and leaves, it has strong potential as human food as well as animal feed and fodder. However, genetic improvement in this crop remains stagnant owing to the poor characterization of its genetic resources. In this study, we characterized 118 accessions of grass pea with 18 EST-SSR markers. A total of 118 accessions, 101 of L. sativus(100 cultivated accessions from Bangladesh and one wild accession) and 17 wild accessions of other Lathyrus species, were used. A total of 67 alleles were detected, with an average of 3.72 alleles per locus and average polymorphism information content of 0.52. A dissimilarity matrix was formed and hierarchical cluster analysis performed using the UPGMA method grouped genotypes into four main clusters. Cluster analysis based on the genetic dissimilarity revealed a clear grouping of the 100 cultivated and 18 wild accessions into four main groups. Group I consisted of 20 accessions with high β-N-oxalyl-L-α,β-diaminopropionic acid(β-ODAP) concentration. Of these 20 accessions, 17 were wild accessions. Only one wild accession(L. cicera) was clustered in group II, which contained 35 accessions. Most of the group II accessions contained low β-ODAP. Group III was represented by 34 accessions, many of them with high β-ODAP. Group IV consisted of 29 accessions, a few of which had very high β-ODAP concentrations. Analysis of molecular variance of the microsatellite data showed significantly higher values of molecular variance between(83%) than within(17%) populations. These characterized accessions will be useful in grass pea breeding programs.Priyanka Gupta Sripada M. Udupa Debjyoti Sen Gupta Jitendra Kumar Shiv Kumar 2018The Crop Journal2018,6,4:2
7Draft genome sequence of a less-known wild Vigna: Beach pea(V. marina cv. ANBp-14-03)显示文摘Beach pea or beach cowpea(Vigna marina(Burm.)Merr.)belongs to the family Fabaceae.It is a close relative of cultivated Vigna species such as adzuki bean(V.angularis),cowpea(V.unguiculata),mung bean(V.radiata),and blackgram(V.mungo),and is distributed throughout the tropics.With its ability to tolerate salt stress,beach pea has great potential to contribute salt-tolerance genes for developing salt-tolerant cultivars in cultivated Vigna species.However,it is still underutilized in Vigna breeding programs.A draft genome sequence of beach pea was generated using a high-throughput next-generation sequencing platform,yielding 23.7 Gb of sequence from 79,929,868 filtered reads.A de novo genome assembly containing 68,731 scaffolds gave an N50 length of 10,272 bp and the assembled sequences totaled 365.6 Mb.A total of 35,448 SSRs,including 3574 compound SSRs,were identified and primer pairs for most of these SSRs were designed.Genome analysis identified 50,670 genes with mean coding sequence length 1042 bp.Phylogenetic analysis revealed highest sequence similarity with V.angularis,followed by V.radiata.Comparison with the V.angularis genome revealed 16,699 SNPs and 2253 InDels and comparison with the V.radiata genome revealed 17,538 SNPs and 2300 InDels.To our knowledge this is the first draft genome sequence of beach pea derived from an accession(ANBp-14-03)adapted locally in the Andaman and Nicobar Islands of India.The draft genome sequence may facilitate the genetic enhancement in cultivated Vigna species.Awnindra Kumar Singh A.Velmurugan Debjyoti Sen Gupta Jitendra Kumar Ravi Kesari Aravind Konda Narendra Pratap Singh Sibnarayan Dam Roy Utpal Biswas R.Rahul Kumar Sanjay Singh 2019The Crop Journal2019,7,5:2
