Cacao trees planted in fields infested with Cassava Witches' Broom Disease can exhibit similar symptoms. Supposedly, Rhizoctonia theobromae from cassava may also be a causal agent of disease in South American cacao.
Scientific colonialism. The same applies to molecular studies on Amazonian species. Most authors are from institutions in São Paulo, or even Europe and North America.

Tomato leaves with late blight caused by Phytophthora infestans
Hello friends of science! I’m migrating over here from X. There, I had 3,000 followers enjoying plant pathology content! Please help me rebuild. I’ll post plant disease photos, management info, science & nature content. Kicking off with some tomato late blight caused by Phytophthora infestans.
What a difference! I did used SEM years ago looking at the effect of essential oils on plant pathogenic bacteria biofilms. I always worried about sample integrity. Despite my effort, so much of the biofilm was washed away during prep.

I'm always arguing that singing karaoke has helped me with my science. Colleagues just laugh... 😅🤷♂️
Iranians are experiencing a collective trauma. Thousands have been killed/injured in recent events, the economy is crippled & the threat of a wider conflict is real. This is especially difficult for those living in Iran, as many have lost (or fear losing) loved ones. www.nature.com/articles/d41...
This work provides a roadmap of the CBB-associated Xanthomonas effector repertoire, raising new questions about host-pathogen interactions. Read the full Open Access paper (free until March 14): authors.elsevier.com/a/1mUpV39MrQ...
I'm open to discussion! What are your thoughts? 💭
The conserved effectors likely point to a convergence in how these bacteria adapted to the common bean. However, the exclusive T3SEs we identified may explain the divergent phenotypes observed in our model strains.
We performed the first comprehensive mining of T3SE genes in CBB pathogens. Surprisingly, we found a high number of conserved T3SE families across both species, suggesting a significant overlap in their molecular toolkit.
The core genome phylogeny showed no geographical clustering. This confirms that CBB dissemination is likely driven by the international trade of contaminated seeds rather than local evolution.
Our pangenomic analysis revealed higher diversity in Xpp (b) compared to Xcf (a). This aligns with Xpp's known higher aggressiveness and virulence variability.
Common Bacterial Blight (CBB) is caused by two distinct species: X. citri pv. fuscans (Xcf) and X. phaseoli pv. phaseoli (Xpp). Despite the same disease, we demonstrate that they interact differently with host genes. So, we set out to map their genomic similarities and differences.

Four months ago, I shared this post. This week, I was at a field day representing Embrapa in a strategic meeting to discuss Cassava Witch's Broom. I continue to advocate for collaborative research that integrates farmers' observations with scientific data to safeguard our crops. 🌱🧪
OMG! It's time to go to Xanthomonas campestris pv. campestris again! 🌱🦠😅

2. Copy the palette HEX codes to davidmathlogic.com/colorblind and observe the palette under different types of colorblindness. Adjust the colors with the cursor to improve distinguishability.
3. You can easily use the color HEX codes in #ggplot. 🧪
For an easy color choosing for scientific figures 🧪 considering colorblind accessibility:
1. Pick your favorite color at www.figma.com/color-wheel/ and choose a palette scheme (for example, set “Complementary” for 2 colors or “Square” for 4 complementary colors).

Wearing this badge with so much pride! I am now a Plant Bacteriology researcher at Embrapa (the Brazilian Agricultural Research Corporation)! 🥳 This is an important step for me, and I'm looking forward to contributing to my country 🤞. #newPI
I believe in the Xanthomonas supremacy in plant bacteriology! 🦠🧎♂️

Wait! So I could be a mermaid 🧜♀️ in Copacabana beach right now? Not bad, huh?
yes. totally. the philosopher may have had the wrong idea at her first glance, though
