Monitoring peroxisome dynamics using enhanced green fluorescent protein labeling in Alternaria alternata.

ABSTRACT: Brown leaf spot on tobacco is a serious fungal disease caused by Alternaria alternata. Peroxisomes are organelles playing an important role in the development and infection of plant pathogenic fungi. But, until now, there is no report on the peroxisome dynamics during the conidia germination of A. alternata. To evaluate the roles of peroxisome in the development of the fungus, in the present work, an enhanced green fluorescent protein (eGFP) cassette tagged with peroxisome targeting signal 2 (PTS2) was integrated into A. alternata to label the organelles, and an eGFP cassette carrying a nuclear located signal (NLS) was performed parallelly. The transformants containing the fusions emitted fluorescence in punctate patterns. The fluorescence of eGFP-PTS2 was distributed
