Isolation and characterization of an endophytic fungi from Zingiber officinale Rosc. and its activity to promote the growth of tissue culture ginger plantlets in bottles

Zingiber Officinale is a perennial rhizomatous vegetable and seasonings with amazing flavor, as well as a wide range of pharmacological activity. Endophytic fungi live within plants, and some of them can help plants adapt to various stress and promote the growth and development of plant. Four endophytic fungi were isolated from ginger rhizome and named GR-1, GR-2, GR-3, and GR-4, respectively. GR-2 promoted the growth of tissue culture ginger plantlets in bottles, and it was identified as Sarocladium strictum. Thus, S. strictum might be a good candidate in the industry of tissue culture plantlet production.
