The study presents the chromosome-level genome assembly of Avena longiglumis, a diploid oat species. The assembly is high-quality, with 99% completeness and 40,845 annotated protein-coding genes. It provides insights into genome evolution, expansion, and structural variations, offering valuable information for oat breeding and functional genomics. Additionally, mitochondrial genome and comparative studies have been conducted.

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…

Saffron crocus, cooking and Iran on the radio
The spice Saffron is valued worldwide for its flavor, aroma and color. I’ve just broadcast an interview with Robin Young produced by Jill Ryan for NPR’s Here and Now program which let me tell you something about my enjoyment of saffron both as a consumer and scientist. Saffron is unusual in that it is equally…
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…

2014 in review: Molecular cytogenetics website activity
The WordPress.com stats helper monkeys prepared a 2014 annual report for this blog. Obviously, my New Year’s Resolution must be to put more of the things I do onto the Molcyt.com website, and not have such long gaps. Of course, half-a-dozen posts of more general interest was also put onto AoBBlog.com and I’ll be planning to…
