Really excited to share our new manuscript on how the #NLR protein #AfsR regulates #Streptomyces antibiotic production - and how we can use its similarity to plant NLR immune receptors to enhance this production! 📄🧵 (1/17) @johninnescentre.bsky.social www.biorxiv.org/content/10.6...

Narrowing it down: deciphering a narrow leaf phenotype in wheat
Wheat is a globally important crop, contributing around 20% of our dietary calories (Shiferaw et al 2013). As the population grows, total wheat production

Overall, these giant granules are a new class of cereal starch and could be utilised for food and industrial applications. This work wouldn't have been possible without the hard work from my coauthors at @johninnescentre.bsky.social and a collaboration with the @quadraminstitute.bsky.social (6/6)

Rose McNelly @rosemcn.bsky.social · 10/07/2026
Finally, we tested the physiochemical properties of the giant granules. Whilst we saw no differences in resistant starch content or granule digestibility, we saw strong correlations between granule size and pasting and viscosity parameters. (5/6)

When we grew the parc6 bgc1 mutants in the field the giant granule phenotype was maintained and had no negative effect on yield or thousand grain weight. (4/6)

Rose McNelly @rosemcn.bsky.social · 10/07/2026
Our parc6 bgc1 mutants produced giant starch granules where nearly 50% of granules larger than 30 µm whereas in wildtype wheat only 7% of granules are bigger than 30 µm. Remarkably some parc6 bgc1 starch granules were 50 µm in size - which has never been seen in wheat starch before. (3/6)

Rose McNelly @rosemcn.bsky.social · 10/07/2026
We show that two factors determine starch granule size - the number of granules initiated and the size of the amyloplast (the organelle in which starch granules form). We combined two mutations (bgc1 and parc6) to simultaneously reduce granule initiation and increase amyloplast size (2/6)

My latest first author paper is now out! (www.science.org/doi/10.1126/...) In this study we generated giant starch granules in wheat. These granules are twice as big as we see in nature and may have uses in food and industry. (1/6)
