The first in a coming array of papers looking at the co-transcriptome of 72 Botrytis genotype in 10 different host plants is out. Summary is the pathogen uses a combination of general virulence and host specific plasticity (not new genes) to infect dicots. www.biorxiv.org/content/10.1...
Combined generalist and host-specific transcriptional strategies enable host generalism in the fungal pathogen Botrytis cinerea
How generalist pathogens infect phylogenetically diverse hosts remains a central question in plant-pathogen biology. In particular, the extent to which broad host range is enabled by genetic variation...

Really neat paper out in @nature.com on an efficient way to produce doubled haploids in sunflower, thanks to the serendipitous discovery of spontaneous haploid parthenogenesis.
That might be the least intelligible sentence I have ever written - great science communication Marco!

The wild side of grape genomics
With broad genetic diversity and as a source of key agronomic traits, wild grape species (Vitis spp.) are crucial to enhance viticulture’s climatic resilience and sustainability. This review discusses how recent breakthroughs in the genome assembly and analysis of wild grape species have led to discoveries on grape evolution, from wild species’ adaptation to environmental stress to grape domestication. We detail how diploid chromosome-scale genomes from wild Vitis spp. have enabled the identification of candidate disease-resistance and flower sex determination genes and the creation of the first Vitis graph-based pangenome. Finally, we explore how wild grape genomics can impact grape research and viticulture, including aspects such as data sharing, the development of functional genomics tools, and the acceleration of genetic improvement.

Important piece by @mikegrunwald.bsky.social. Food systems convos can get polarized between “boost yields” vs “reduce env. harms” vs “change consumption patterns.” The reality, as this piece describes, is that the 🌎 needs to do it all to feed 9-10 billion people while protecting nature & climate.

Our first Bluesky post contains some good news for #fungi! After a long history of being unprotected, COP16 marked a huge advancement in the conservation of fungi. 🍄🥳

Thanks to work led by our partners at Fungi Foundation, The Fungal Conservation Pledge was introduced at #COP16. bit.ly/3Vl9GHL
Why Fungi Could Get Higher Conservation Status And Why It Matters
The UK and Chile are proposing at the UN’s biodiversity conference COP16 in Colombia that fungi receive the same status to animals and plants. This could help foster and funding research.

What scares me about natural disasters like #earthquakes is how unreliable the notification system seems to be. Why are half of the people notified and the other half get no messages? Is it about phone brands, networks? Is it about settings on the phones? Is it about authorizing localization?
