DNA 2022, 2(1), 86-103; Free full text: https://doi.org/10.3390/dna2010007 Endogenous retroviruses (ERVs) represent genomic components of retroviral origin that are found integrated in the genomes of various species of vertebrates. These genomic…

New Project on Molecular Cytogenetics and Genomics of Ensete banana

We have a research project starting in 2017 on Ethiopian banana, Ensete ventricosum, for 18 months, in collaboration with Royal Botanic Gardens, Kew (Dr Paul Wilkin) and University of Addis Ababa (Professor Sebsebe Demissew). There is a post-doctoral position working with the project (closed 7 August 2017). The project “Modelling and genomics resources to enhance…

Domestication, polyploidy and genomics of crops and weeds PAGXXV

Plant and Animal Genome Conference in San Diego #PAGXXV each January is the chance to join 3500 people working in genomics. I presented a talk on the molecular cytogenetics group’s work, starting with consideration of early stages of crop domestication, and then thinking about how we can make agriculture more sustainable. I also considered weeds,…

Regulation should follow robust scientific assessments not opinions

University of Leicester scientist in battle to ‘stem onslaught of pseudoscience’ Geneticist at European Commission alarmed at impact of ‘dogma’ in regulation and the negative impact on the environment and European industry A University of Leicester scientist has joined leading scientists from across Europe in raising an alarm over the ‘pseudoscience’ concerning regulation of compounds used…

Saffron Crocus, quality and fraud in New York Times

Elaine Sciolino discusses saffron in the New York Times. Saffronomics partners Jean Thiercelin and Pat Heslop-Harrison are quoted, with the outcome of the project in developing methods to detect fraud and measure quality. In the article, the special qualities of saffron are discussed and many examples of the use in sweet and savoury foods explain the value in…

Diversity and characters in Ethiopian linseed Linum #PAGXXIII Negash Worku

Many people have talked about Orphan crops – those where there has been little genetic or other research – and the characterization, evaluation and exploitation of germplasm at the #PAGXXIII Plant and Animal Genome Conference this week. Today, I am talking about work by Negash Worku on the Diversity and Characters in Ethiopian Linseed Accessions….

Needs for understanding water and food security

“The earth’s land surface receives about 110,000 km3 of rainfall annually. More than half of this water is evapotranspired (transmitted from soils and through plants to the air); about 20,000 km3 falls on land that is cultivated in some form; and about 40,000 km3 becomes available in dams, lakes, rivers, streams and aquifers for human…

Chromosomal evolution in Brachiaria forage grasses with Fabiola Carvalho Santos

Fabiola Santos from University of Londrina, Brazil, is working on the Chromosomal evolution and the organization of repetitive DNA sequences in diploid and polyploid Brachiaria forage grasses in the molecular cytogenetics group in Leicester. Brachiaria is most important cultivated forage grass genus in Brazil (with billion-dollar production), and the genus includes diploid and polyploid species with similar…

Aquaculture, farming and development: an FAO consultation

Aquaculture has major prospects for providing high quality, palatable protein for people. Compared to other animals, the conversion of plants into animal protein in fish, shellfish and crustaceans is very efficient: the ratio of input food to output is less than 2:1 (typically 1.6 to 1.8:1), compared to 2.5 to 3:1 for pigs and poultry,…

Fertilizer statistics: changes and usage

Fertilizer has been critical to crop yields from the start of agriculture, and the application of artificially fixed nitrogen has been fundamental to crop yield increases since the 1970s. However, finding definitive data about absolute amounts, costs, effects on yields and changes in application is tricky – with dispersed literature, many units, confusion with sales…
