The target is the fearsome fungal disease wheat blast. The pathogen was spotted in Bangladesh in February this year—its first report in Asia. Wheat is the second major food source in Bangladesh, after rice. The blast disease has, so far, caused up to 90% yield losses in more than 15,000 hectares. Scientists fear that the pathogen could spread further to other wheat growing areas in South Asia. The UK and Bangladeshi teams are making raw genetic data for the wheat blast pathogen available on a new website—http://www.wheatblast.net—and inviting others to do the same. Professor Sophien Kamoun, of The Sainsbury Laboratory in Norwich, who is leading the project, said that a wide cultural change is needed for scientists to optimally address new threats to food security. "I have a beef with the way that research is typically done. We need a fundamentally new approach to sharing genetic data for emerging plant diseases," he said. "We need to generate and make data public more rapidly and seek input from a larger crowd because, collectively, we are better able to answer questions." Professor Kamoun, with colleagues at The Genome Analysis Centre and John Innes Centre in Norwich, and with Professor Tofazzal Islam's Team of Bangabndhu Sheikh Mujubur Rahman Agricultural University (BSMRAU) in Bangladesh, is hoping that the wheatblast.net website, together with an accompanying Facebook page, will provide a hub for information, collaboration and comment. They are basing the site on their successful Open Ash Dieback website, which brought scientists together in the fight against ash dieback disease. The blast fungus normally infects rice and over 50 types of grasses. Occasionally, a blast fungus strain would jump from one host to another resulting in a new disease. Such a "host jump" to wheat has happened in Brazil in the 1980s. The wheat blast pathogen is now rife in South America, where it infects up to 3 million hectares and causes serious crop losses. Prof Kamoun and colleagues are working with Professor Tofazzal Islam's team, of the Department of Biotechnology of BSMRAU in Gazipur, Bangladesh. They hope that the genetic data will help determine whether the Bangladeshi wheat-infecting strain has evolved independently from local grass-infecting fungi or was somehow introduced into the country. Professor Tofazzal Islam said "This pathogen causes a destructive disease on rice and it would be disastrous if the same situation arises now in wheat. Genomic and post-genomic research should clarify the origin of the wheat strain and guide measures for disease management. Prompt responses are needed from the scientific community and the government of Bangladesh for addressing this national crisis to ensure increasing wheat production, which is linked with future food and nutritional security of the nation." The group of scientists includes Dr Diane Saunders at The Genome Analysis Centre and John Innes Centre who developed a technique last year, known as Field Pathogenomics. To date, Field Pathogenomics has been applied to track another fungal crop disease - yellow rust. The method generates highly-specific genetic information directly from diseased wheat samples to determine the identity of the pathogen strain that's associated with an epidemic. Application of this method to wheat blast should unmask the pathogen in Bangladesh and contribute to a response plan. The recent wheat blast epidemic in Bangladesh has prompted Professor Nick Talbot, University of Exeter, to post on the wheatblast.net website a set of genetic data generated by his group from worldwide populations of the wheat and rice blast fungus. Prof Talbot said "In an emergency like this one, the community must come together to share data and compare notes. Only then, we will determine the true identity of the pathogen and put in place effective measures in a timely fashion." Professor Neil Hall, Director of The Genome Analysis Centre said: "It is critical in emerging crises like this that scientific data is rapidly generated and made available as soon as possible. Having an open-access site has already galvanized open exchange of information for the ash dieback disease. The scientific community needs to rally behind open science to respond to recurrent threats to global food security."

Common bean is an important and diverse crop legume with several wild relatives that are all part of the Phaseoleae tribe of tropical crop legumes. Sequence databases have been a good source of sequences to mine for simple sequence repeats (SSRs). The objective of this research was to evaluate 14 sequence collections from common bean for SSRs and to evaluate the diversity of the polymorphic microsatellites derived from these collections. SSRs were found in 10 of the GenBank sequence collections with an average of 11.3% of sequences containing microsatellite motifs. The most common motifs were based on tri- and dinucleotides. In a marker development programme, primers were designed for 125 microsatellites which were tested on a panel of 18 common bean genotypes. The markers were named as part of the bean microsatellite-database (BMd) series, and the average polymorphism information content was 0.404 for polymorphic markers and predicted well the genepool structure of common beans and the status of the wild and cultivated accessions that were included in the study. Therefore, the BMd series of microsatellites is useful for multiple studies of genetic relatedness and as anchor markers in future mapping of wide crosses in the species. © 2012 Blackwell Publishing Ltd.

COPENHAGEN, 14-Nov-2016 — /EuropaWire/ — The Board of the University of Copenhagen has found the person to succeed Ralf Hemmingsen as leader of the university for the next five years. On 1 March 2017, the current Provost at the Technical University of Denmark, Henrik C. Wegener, will become Rector of the university. A total of 26 persons applied for the position. The University of Copenhagen’s new Rector knows about bacteria, infectious diseases – and about running a university. Henrik Wegener has a PhD in microbiology from the Royal Veterinary and Agricultural University, which merged with the University of Copenhagen in 2007. After his PhD degree he has, among other things, been Head of Research, Professor, Centre Director, Institute Director and, since 2011, Provost at the Technical University of Denmark in charge of research, research centres, collaboration agreements, international relations, etc. Henrik Wegener holds a Master of Public Administration and serves as one of the EU Commission’s top research advisers. “We’ve had a strong and broad field of applicants. The Board has chosen Henrik Wegener because he has both the professional and personal competences required, and because he has created excellent results throughout his career, both as a researcher and in leadership roles. Altogether, he has 18 years of leadership experience at all levels. He has been in charge of large-scale change processes, and is recognised for working through dialogue and involvement of the entire organisation, and for achieving the goals of the initiatives he launches. The University of Copenhagen will get a leader who has good knowledge of the university, but who also has an outsider’s new and refreshing view of the tasks ahead. And then he understands how a university can impact framework conditions for research as well as the importance of protecting the integrity of the university,” Nils Strandberg Pedersen says. Henrik Wegener is an internationally recognised researcher within food safety, antibiotic resistance and bacterial zoonoses, i.e. bacteria transferred from animals to humans. As a researcher he has been working with applied research at four sector research institutions: The Danish Veterinary Serum Institute, the Danish Zoonosis Centre, Denmark’s National Veterinary Institute and the Danish Institute for Food and Veterinary Research, all of which are now merged with the Technical University of Denmark. For a number of years he served as national expert to the World Health Organisation, WHO. As Provost at the Technical University of Denmark, he has had the overall responsibility for the university’s research activities. In addition, he has extensive experience of collaboration with public and private sector players, nationally and internationally. “The University of Copenhagen is the most important university in Denmark. The university must continue to address society’s need for new knowledge and talented graduates. Quality of education and basic research at the highest international level should therefore still be top of the agenda. The university must be developed through a determined focus on high-level research, keen priorities, global recruitment of researchers as well as inspiring and demanding research-based teaching of an international standard. The same goes for the efforts to develop a professional and coherent administration in collaboration with staff and students. And then, of course, we will continue to focus on safeguarding the university’s external interests, and not least maintain our independence,” Henrik Wegener says.

Wheat × Imperata cylindrica-mediated approach of doubled haploidy breeding requires hand emasculation followed by pollination with I. cylindrica pollen. The pace of this endeavour can be enhanced by utilizing asynchronous flowering of wheat spikes by direct pollination without emasculation followed by morphological marker-assisted screening of selfed and crossed seeds. The emasculated and un-emasculated spikes of 13 spring and six winter wheat genotypes and two triticale × wheat derivatives were pollinated with I. cylindrica pollen. The response of different genotypes for production of crossed and selfed seeds with direct pollination varied significantly within and between groups for spring and winter wheats, whereas triticale × wheat derivatives responded similarly to each other but significantly different from spring and winter wheats. Although, the proportion of pseudoseed formation was lower in case of direct pollination, yet in some genotypes, it was comparable to that of pollination after emasculation. Moreover, the response for haploid embryo induction frequency was similar in both the cases. The method of direct pollination can be utilized for easy and economical induction of haploids. © 2013 Blackwell Verlag GmbH.

Colchicine doses ranging from 100 to 10 000ppm with and without 2, 4-D application were administered in vivo to the uppermost internodes of Imperata cylindrica-pollinated wheat plants at various intervals for assessing the potent concentration required for doubling of chromosomes. Although injection of single dose of colchicine concentration ranging from 2000 to 5000ppm at 48h after pollination yielded good response, 2000ppm was found to be the most effective and economically viable dose of colchicine for DH production. Very high doses have also responded to the doubling of the chromosomes, but the recovery of the embryos and regenerated plantlets was very poor. The doubling of the chromosomes was confirmed cytologically from the roots of the regenerated plantlets. The results of this study not only enhanced the production efficiency of DHs but also saved the time and energy required for the chromosome doubling in the haploid embryo-regenerated plantlets. These results bear far-reaching implications in the accelerated genetic upgradation of bread wheat and development of homozygous populations for mapping of targeted genes. © 2012 Blackwell Verlag GmbH.

The study has been performed to analyze the content of nitrates V and III as well as lead and cadmium in Brassica vegetables, both fresh and after 5-month storage in a cool storeroom. The experimental material consisted of Chinese cabbage, red and white cabbage, savoy cabbage and Brussels sprouts. The content of nitrates in the plant material was determined with the spectrophotometric method based on Griess reaction, whereas concentrations of heavy metals were assayed with the AAS method after dry mineralization. The 5-month storage period was found to decrease (by ca 65±5%) the content of nitrates V in savoy cabbage and Brussels sprouts. In turn, a ca 2-fold increase in the concentration of these compounds was determined in Chinese cabbage, and a similar tendency was observed in white cabbage. Chinese cabbage turned out to be the richest in the analyzed, undesirable elements and compounds, e.g. after storage it was characterized by an exceeded permissible level of nitrates V (750 mg kg-1 f.w.) and by the biggest, ca 10-fold, increase in concentrations of lead and cadmium. Besides, storage was observed to cause a significant increase in the content of nitrates III in the analyzed vegetables, except red cabbage, in which their content was shown to decrease by about 40%. Concentrations of nitrates III and V, Pb2+ and Cd2+ in tissues of the cabbage plants should be monitored regularly in order to prevent their excessive accumulation in the food chain of man.

BACKGROUND: Cold stress at reproductive phase in susceptible chickpea (Cicer arietinum L.) leads to pollen sterility induced flower abortion. The tolerant genotypes, on the other hand, produce viable pollen and set seed under cold stress. Genomic information on pollen development in cold-tolerant chickpea under cold stress is currently unavailable.RESULTS: DDRT-PCR analysis was carried out to identify anther genes involved in cold tolerance in chickpea genotype ICC16349 (cold-tolerant). A total of 9205 EST bands were analyzed. Cold stress altered expression of 127 ESTs (90 up-regulated, 37 down-regulated) in anthers, more than two third (92) of which were novel with unknown protein identity and function. Remaining about one third (35) belonged to several functional categories such as pollen development, signal transduction, ion transport, transcription, carbohydrate metabolism, translation, energy and cell division. The categories with more number of transcripts were carbohydrate/triacylglycerol metabolism, signal transduction, pollen development and transport. All but two transcripts in these categories were up-regulated under cold stress. To identify time of regulation after stress and organ specificity, expression levels of 25 differentially regulated transcripts were also studied in anthers at six time points and in four organs (anthers, gynoecium, leaves and roots) at four time points.CONCLUSIONS: Limited number of genes were involved in regulating cold tolerance in chickpea anthers. Moreover, the cold tolerance was manifested by up-regulation of majority of the differentially expressed transcripts. The anthers appeared to employ dual cold tolerance mechanism based on their protection from cold by enhancing triacylglycerol and carbohydrate metabolism; and maintenance of normal pollen development by regulating pollen development genes. Functional characterization of about two third of the novel genes is needed to have precise understanding of the cold tolerance mechanisms in chickpea anthers.

Intergeneric hybridization in seven diverse durum wheat genotypes was carried out using two composite varieties of Himalayan maize, viz., Bajaura Makka and Early Composite, and a wild grass, Imperata cylindrica, as pollen sources. Observations related to various haploid induction parameters put forth I. cylindrica as significantly better pollen source for haploid induction in durum wheat over maize in terms of pseudoseed formation (46.93%), embryo formation (38.06%), haploid regeneration (40.42%) and haploid formation efficiency (7.44%). The line x tester analysis revealed that both male and female genotypes had significant effects on all haploid induction parameters except haploid formation frequency in later. Among the pollen sources, I. cylindrica emerged as best combiner based on GCA values when compared with the two Himalayan maize composites. Durum wheat genotype, A-9-30-1 was recognized as the best general combiner followed by PDW 314. The present investigation proposed durum wheat × I. cylindrica as a superior technique over maize-mediated system, and its large-scale use can open a new horizon in the sphere of durum wheat doubled haploidy breeding programme. © 2015 Blackwell Verlag GmbH.
