Temperature-susceptible (green) and temperature-resilient (orange) modules are indicated. The identification of CBP60g and SARD1 transcription as the primary thermo-sensitive step in the SA pathway downstream of GBPL3 prompted us to test whether expression of CBP60g and SARD1 is a rate-limiting step for SA production at elevated temperature and, if so, whether restoring CBP60g and SARD1 expression would sufficiently render SA production resilient to increased temperature.

Binding of TGA1-myc to CBP60g locus is not affected by temperature in mock (0.1% DMSO)- or BTH-treated samples (P-value=0.7903 and 0.9566, respectively). The column was washed with lysis buffer, and His-tagged proteins were eluted with elution buffer consisting of 25 mM Tris-HCl, 300 mM NaCl, 300 mM imidazole and 10% glycerol, pH 7.7. Because ETI is widely used to guard crops against pathogens and insects28,36, these results suggest potentially broad applications of restoring CBP60g expression to counter suppression of not only basal immunity to virulent pathogens, but also ETI at elevated temperature. Together with these studies, our results support an emerging general concept that biomolecular condensates serve as an important regulatory node for plant sensing and/or response to external temperature and other environmental cues.

There are five basic steps of DNA extraction that are consistent across all the possible DNA purification chemistries: 1) disruption of the cellular structure to create a lysate, 2) separation of the soluble DNA from cell debris and other insoluble material, 3) binding the DNA of interest to a purification matrix, 4) washing proteins and RNA-seq reads of the mock- and Pst DC3000-inoculated Arabidopsis Col-0 plants at normal and elevated temperature. 1i), raising the possibility that expression of CBP60g or SARD1 may be the primary target in SA suppression at elevated temperature.

Mitochondrial DNA (mtDNA) was chosen as the genetic marker because copy number of mtDNA is greater than that of nuclear DNA per cell, and detection rate therefore is expected to be higher in the former, even where DNA is present at a low concentration and/or is degraded [].In order to select a suitable region in the c, d, e, CFUs in caecum, spleen and liver, respectively, were measured at day 6 after infection.
