Widespread genomic islands are hotspots of genome variations and mosaicism in giant viruses - Nature Communications
Researchers analyzed 369 giant virus genomes and identified widespread genomic islands, regions of rapid gene turnover that help these viruses adapt to hosts and even exchange genes with bacteria, revealing new insight into viral genome evolution.Nature

Fungi get injured too. 🍄💥
And when a microscopic fungal thread breaks, things can go wrong very quickly.
So how do fungi stop the damage and keep the rest of their network alive?

A symbiotic origin of the ribosome?

I grew these mushrooms in a cloth grow bag using only wood chips as the substrate. I thought that they would fruit in the top, but instead they actually fruited through the fabric in the bottom.
They struggled a bit due to the low humidity indoors, but I spray them with water several times a day, so I will be able to harvest something.

Actinomycete genomes are a rich source of unexplored phosphonate natural products. By mining 940 genome sequenced strains, researchers found 54 candidate producers and confirmed phosphonate production in 21 strains, including Kitasatospora fiedleri with a unique, LuxR regulated gene cluster. This strategy paves the way for new bioactive phosphonates with pharma and biotech potential.

Esther Lederberg (December 18, 1922 – November 11, 2006) pioneered bacterial genetics, discovering lambda phage and F factor, inventing replica plating and furthered the understanding of the transfer of genes between bacteria by specialized transduction. She founded Stanford's Plasmid Reference Center. Despite groundbreaking work, she never got tenure and her discoveries are often credited to her Nobel laureate husband.

#bioinformatics #microbiology #assembly question. I'm looking through some new archaeal genome assemblies, and some of the species show perfect assembly output except in one plasmid - always in about 1k different contigs of braided alternate paths but graph together nonetheless. Is this a biological signature of something?

Exciting work from the Hsu lab at Virginia Tech! They developed a cool way too knock down phage abundances to examine their role in the gut.
"A bacteriophage-conditional mouse model reveals the impact of phages within a conventionally colonized gut microbiota"
We found a really cool giant virus inside the genome of a green alga, and it has a very strange infection cycle that is hard to detect.
There are reports going back decades of viral particles spontaneously appearing in pure cultures of green algae, so this phenomenon seems quite common but mostly overlooked.

Not a bad hair day for Phage 7-7-1
Noteworthy — While the phages χ and PBS1 attach to the flagella of their hosts via the tail fibers, phage 7-7-1 of Agrobacterium sp. H13-3 has another trick up its sleeve – or better: on its head (capsid). Noteborn et al. Found that phage 7-7-1 sports a bunch of dreadlocks on its head, proteinaceous fibers with which it attaches to host flagella.
