Symptoms of Tomato spotted wilt (virus) on bell pepper at the local garden store in town. You just never know what you will find on the back shelf. The disease is transmitted by thrips during feeding. There are many hosts including tomato and peanut #Virus #TSWV #Tomato

Very excited to see my first first author paper published in PNASNews . We found the first effector regulator in plant-parasitic nematodes! Congratulations to all authors and co first author Clément Pellegrin. pnas.org/doi/10.1073/pn…

Chemistry is everywhere. Amino acids are the building blocks of proteins. There are over 500 amino acids found in nature however, the human genetic code only directly encodes 20. ‘Essential’ amino acids must be obtained from the diet, others can be synthesized in the body.

How do you know if I have a nematode problem? Here's your sign!

First #soil in Cameroon is this Oxisol (way top of road cut) weathering in gniess. We dug around that gniess a lot looking at saprolite weathering. Man on the left is my gracious host Dr. Georges Ndzana of Dschang U.

Septoria tritici blotch caused by #Zymoseptoria tritici, observed today on bread #wheat (Triticum aestivum) in field trials (Versailles, FR).

An iconic peach pathogen for the diagnostics class.

Corn fields in North AL are presenting this problem. Holcus leaf spot caused by the bacterium Pseudomonas syringae results in small, round to oval spots on leaves. Wet and mild weather conditions are in favor of this. Fortunately, it has no impact on yield. Alabama Extension CSES Auburn University

I've spent the last month or so processing cynipini larval transcriptome data from live oak galls provided by Scott P. Egan and Maryam R Faghihi last fall. No conclusions yet on the question of interest (what are the gall-induction effectors) but some basic bio observations:
