Growth of Aspergillus flavus and A. parasiticus on nontransgenic maize controls and on maize transgenics expressing the CYP51A/CYP51B RNAi construct. (A) Nontransgenic B104 kernels inoculated with A. flavus, A. parasiticus, and noninoculated control. (B) Kernels from CYP51A/CYP51B transgenic plants (event 15) inoculated with A. flavus, A. parasiticus, and noninoculated control. (C) Nontransgenic B104 cobs inoculated with A. flavus, A. parasiticus, and noninoculated control. (D) Cobs from CYP51A/CYP51B transgenic plants (event 2) inoculated with A. flavus, A. parasiticus, and noninoculated control. 3 and 6 DAI: days after inoculation. Aspergillus growth was visually assessed based on the degree of mycelial development and sporulation, as indicated by green coverage on the kernels. In the original image for Panel D, the transgenic cobs were arranged horizontally; for consistency with the nontransgenic control, images of the cobs for each treatment were cropped, rotated to a vertical orientation, and enlarged to approximately match the size of the nontransgenic cob images. (Scale bar = 5 cm.)

Something I learned recently: many people assume SMSA is a selective medium for Ralstonia solanacearum. It's not, it's semi-selective, and lots of other microbes can grow on it. Spotting Ralstonia takes a good eye 😉🦠 #PlantPathology #Microbiology

FIGURE 1: Experimental design for dissecting the WTK1-mediated signaling network. Schematic overview of the workflow used to compare resistant (Kronos R) and susceptible (Kronos S) near-isogenic lines following inoculation with Puccinia striiformis f. sp. tritici (Pst) isolate #5006. The experimental pipeline comprised: (1) a 7-day time-course experiment with sequential leaf sampling; (2) histopathological analysis of fungal colonization, together with measurement of reactive oxygen species (ROS) accumulation; (3) time-course RNA-Seq profiling; and (4) qRT-PCR validation of selected transcriptomic responses. hpi, hours post-inoculation; WGA, wheat germ agglutinin; H2DCFDA, 2′,7′-dichlorodihydrofluorescein diacetate.

🥔Ralstonia solanacearum injects RipBH into potato cells, where it cuts itself in two to become active, then disrupts cellular homeostasis from the inside. No immune receptor needed. New study reveals the mechanism behind this self-activating toxin.
