Very happy to celebrate #WomenInScience today. Extra special thanks to the brilliant scientists I work with: first author publications from Qing, Paulina, Janet, Shuyu, Katja, Neha, Iza, Trude, Ana-Claudia, Adel and Dinaiza over the last couple of years.

Endogenous retroviruses ERVs in sheep are 0.55% of the genome and different families have different genomic distributions: some centromeric (except on 2 metacentric chromosomes), others more dispersed, with lovely in situ pictures from Sarbast Mustafa biorxiv.org/content/10.110…

University of Leicester celebrating 100Years of success! we molecular cytogenetics research group @ Dept. Genetics and Genome Biology, UOL. celebrate this amazing moment preparing this using our research materials (28days old 1000 Brassica juncea seedlings).

From Priyanka Rathore, Vishnu Bhat & Paulina Tomaszewska retroelements (red) and anti-methylcytosine (green) in tetraploid 4x allopolyploid topical forage grass: Repetitive DNA sequence landscape and DNA methylation in chromosomes of apomictic Cenchrus ciliaris biorxiv.org/content/10.110…

This will be one of those moments I will never forget. Congratulations to Her Royal Majesty the Queen on her Platinum Jubilee

Our paper on Cenchrus with Priyanka Rathore, Paulina Tomaszewska et al. differentiating the two ancestral genomes in the allotetraploid and showing 5-methylcytosine methylation sites at most retrotransposon sites on the chromosomes in the 2n=39 line studied

In a new #PhDBlog, Kate writes about her trip to Colombia, where she worked with collaborators at Alliance of Bioversity International and CIAT, to gain local knowledge and practical experience with local growers and experts in common bean crops. ➡ okt.to/I53Oow Kate Denning-James NRPDTP @jjdeveg

Publication of Annals of Botany Special Issue with 17 papers on Polyploidy in Ecology and Evolution this afternoon academic.oup.com/aob/issue/131/1 (all papers free). Qing Liu, Trude Schwarzacher and my Preface-Review on consequences and enabling role of polyploidy is doi.org/10.1093/aob/mc…

🧬 #AoBPolyploidyWeek Complex polyploid and hybrid species in an apomictic and sexual tropical forage grass group: genomic composition and evolution in Urochloa (Brachiaria) species by Paulina Tomaszewska and co-authors in Annals of Botany #openaccess 👉 doi.org/10.1093/aob/mc… 1/2

Our latest on Chrysanthemum genomes Fengjiao Zhang Graph-based clustering/k-mer analysis classify repetitive motifs. Surprisingly few tandemly repeated sequences, lots of low-complexity derived from transposable elements #genomics #repetitivedna #transposableelements Annals of Botany

Jeffrey Ross-Ibarra Cedar Warman 🍅🌵🌈 Also biased, but doi.org/10.1093/aob/mc… @jjdeveg Paulina Tomaszewska 10Gb RNA-seq from 111 Urochloa forage grass lines shows diverged ecotypes/subpopulations of polyploids and with the apomictic character can be utilized in breeding fixed hybrids

📣CONFERENCE ALERT‼️ Next year we’re organizing the PLANT MEIOSIS MEETING🎉 In Poznan, Poland😎 On September 4-6, 2024🤩 Mark this date on your calendar‼️ If the words MEIOSIS and PLANTS make you shiver, this meeting is just for you🤯 More details coming soon‼️‼️

The website for the American #Oat Workers' Conference (AOWC) in Saskatoon, Canada, next July is now up! conferences.usask.ca/aowc2024/ Anyone anywhere who works with #oats is welcome to attend the meetings. Details of the program will be available in the coming months.

Our diploid oat genome assembly is now published Liu Q, Xiong G, Wang Z, Wu Y, Tu T, Schwarzacher T, Heslop-Harrison JS. 2024. Chromosome-level genome assembly of the diploid oat species Avena longiglumis. Scientific Data 11: 412. doi.org/10.1038/s41597… molcyt.org/2024/04/22/ave…

As part of a special issue on 'African Flora in a Changing World', give our paper on the evolution of forage grasses in the African genus Urochloa a read! Lots of polyploidy, lots of convergence, lot of fun 🌾

Enjoyed the talk by Pat Heslop-Harrison and Trude Schwarzacher on endogenous pararetroviruses at #IBC2024. I still fondly recall my time in their lab University of Leicester as a master's student, learning from the best in cytogenetics. Grateful to them for guiding me toward what I now love so much!
