var. Hara was collected from farmland in Seongju-gun. Fifteen endophytic fungal strains
with different colony morphologies were isolated from roots of . Waito-c rice seedlings were treated with the
concentrated culture filtrates (CF) of endophytic fungi for observation of their plant growth-promoting activities. In the results, the
CF of Y2H001 fungal strain promoted the growth of the waito-c rice seedlings. The phylogenetic tree of Y2H001 strain was
analyzed by the combined sequences of the partial internal transcribed spacer region (ITS) and partial betatubulin gene.
Molecular and morphological studies identified the Y2H001 strain as belonging to . In gas chromatography mass
spectrometry (GC/MS) analysis of the CF of Y2H001 strain, gibberellic acid (GA) was detected and quantified. Therefore, we
describe Y2H001 strain as a new GA-producing based on morphological, molecular characteristics and analysis of
