some philosophers use biological science concepts with mastery; some others do not. I was reviewing a quote suggesting an opposition between symbiosis and Darwinian evolution. do some of you agree with it? 🤔

Working on a new plant bacterial disease report! However, there’s a 2015 genome announcement of a bacterium from the same genus causing disease on the same plant as my work... 🤔 I obviously decided to compare 🔎.

Elementary 3D organization of active and silenced E. coli genome - Nature
An ultra-high-resolution chromatin organization map of E. coli, using Micro-C, reveals intricate chromatin structures involved in the silencing of horizontally transferred genes and those associated with active operons.

Considering the Federal situation, campuses are encouraging labs to enter partnerships with industry.
A plant breeding company reached out to see if my lab could rate their plant lines for their resistance to Ralstonia. I said "maybe, but these assays require personnel time and materials"

Cassava growers often see this: brown necrosis starting at the leaf edges and spreading inward.
What’s the most likely cause?
• Fungal pathogen
• Bacterial pathogen
• Viral pathogen
• Nematodes
Drop your diagnosis!
Answer revealed tomorrow.
