Identification and characterization of mobile genetic elements LINEs from Brassica genome
Nouroz F, Noreen S, Khan MF, Ahmed S, Heslop-Harrison JS. 2017. Identification and characterization of mobile genetic elements LINEs from Brassica genomes. Gene 627: 94-105. doi: 10.1016/j.gene.2017.06.015.. Abstract Among transposable elements (TEs), the LTR retrotransposons are abundant followed by nonLTR retrotransposons in plant genomes, the lateral being represented by LINEs and SINEs. Computational and molecular approaches were…
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…

Banana, Ensete and Boesenbergia Genomics talk by Schwarzacher, Heslop-Harrison, Harikrishna
Comparative genomic analysis in Zingiberales: what can we learn from banana to enable Ensete and Boesenbergia to reach their potential? Talk for Plant and Animal Genomics #PAGXXV Molecular cytogenetics can address challenges in crops with relatively little background knowledge. This talk shows some work around Ensete ventricosum, known as enset, ensete, False banana, Abyssynian or…

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…
