Food from Grass: Genetics and Digital Twins to optimize ruminant agricultural sustainability molcyt.org/2024/09/10/foo… for @UKDairyDay showcasing the best genetics, husbandry and technology for milk production

Enjoyed the talk by @Pathh1 and Trude Schwarzacher on endogenous pararetroviruses at #IBC2024. I still fondly recall my time in their lab @uniofleicester as a master's student, learning from the best in cytogenetics. Grateful to them for guiding me toward what I now love so much!

@LizoMasters Well done Lizo.

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 🌾

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…

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.

📣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‼️‼️

@jrossibarra @CedarWarman Also biased, but doi.org/10.1093/aob/mc… @jjdeveg @dr_PTom 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

Our latest on Chrysanthemum genomes @fengjiao11 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 @annbot

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, @trudeschw and my Preface-Review on consequences and enabling role of polyploidy is doi.org/10.1093/aob/mc…

In a new #PhDBlog, Kate writes about her trip to Colombia, where she worked with collaborators at @BiovIntCIAT_eng, to gain local knowledge and practical experience with local growers and experts in common bean crops. ➡ okt.to/I53Oow @katdenjam @NRPBIODTP @jjdeveg

Our paper on Cenchrus with Priyanka Rathore, @dr_PTom 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

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

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).

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.
