It suggests that UvHOX2 can also be involved in responses to oxidative, osmotic, and cell wall stresses.Subcellular Place and Expression Patterns of UvHOXThe UvHOX2-eGFP construct was transformed into wild-type strain P-1. The mutant HOX-GFP-2 was picked from a batch of transformants for its strong signal in the over-expressed eGFP fusion protein. The eGFP signal within the HOX-GFP-2 mycelia situated within the nuclei (Figure 7A). 4 ,6-diamidino-2-phenylindole (DAPI) was used to dye the mycelia and show the D-Fructose-6-phosphate (disodium) salt MedChemExpress location with the nuclei in the cells. The expression levels of UvHox2 in the stages of mycelium growth, conidium generation, and chlamydospore formation had been determined by qRT-PCR. The results showed that the expression of UvHox2 was the highest during the early stage of chlamydospore formation and decreased in the later stage of chlamydospore formation. Meanwhile, the expression of UvHox2 was also high in the sporulating stage as well as the early stage of infection on rice. In contrast, the expression of UvHox2 was low throughout vegetative growth (Figure 7B).pCas9-tRPDThis studypCas9-tRPDI pCas9-tRPDII Pcccd pCccd-dT pCccd-dTN3 pdTN3-HX2-Cas9I pdTN3-HX2-Cas9IIThis study This study This study This study This study This study This studyThe Worldwide Transcription Pattern of UvHox2 Deletion Mutant Differs From That from the Wild Kind in the Early Stage of Chlamydospore DevelopmentTo recognize putative regulated targets from the homeobox TF UvHOX2 throughout the formation from the chlamydospore generation structure, we compared the worldwide gene transcription patterns within the UvHox2 deletion mutant DHOX-61 with that inside the wild-type strain P-1 by RNA-seq evaluation. We inoculate P-1 (WTC) and DHOX-61 (DH) on rice as described above and collected rice false balls af.
