Fig. 2. Subcellular localization of CsNsdD in Colletotrichum siamense. A, Subcellular localization of CsNsdD in the conidia of C. siamense. B, Subcellular localization of CsNsdD in the hyphae of C. siamense. White arrows indicate the position of nuclei with the green fluorescent protein (GFP) signal, and the nucleus was further stained by DAPI (4′,6-diamidino-2-phenylindole) for visualization. CsWT-eGFP, the wild-type strain transformed with the eGFP gene; CsNsdD-eGFP, the wild-type strain transformed with the CsnsdD-eGFP fusion gene. Bars = 10 μm. DIC, differential interference contrast.

The genus #Colletotrichum infects over 3,000 monocot and dicot plant species, inflicting substantial economic losses globally. Jinhong Wang et al. characterized the GATA transcription factor NsdD in C. siamense and C. graminicola, respectively. Learn more: https://doi.org/10.1094/PHYTO-07-25-0238-R
