“…One significant event in plant defense reactions is oxidative burst, a general early response of host plant cells to pathogen infection and elicitor treatment (Almagro et al, 2009). Peroxidase also participates in the production of ethylene the concentration of which increases frequently in pathogenesis process (Tudzynski, 1997).…”

“…Gibberellins (GA) is a family of diterpenoid plant harmones, first detected in 1930s from culture filtrates of Gibberella fujikuroi, a known pathogen of rice plants (Tudzunski 1997). GA appears to be involved in every aspect of plant growth and development, but their most spectacular property is the enhancement of stem growth (Nishijima et al 1995).…”

Endophytic fungi are plant symbionts that produce a variety of beneficial metabolites for plant growth and protection against herbivory and pathogens. Fourteen fungal samples were isolated from the roots of soybean cultivar Daemangkong and screened on waito-c rice for their plant growth-promoting capacity. Twelve of the fungal isolates promoted plant growth, while two inhibited it. The fungal isolate DK-1-1 induced maximum plant growth in both waito-c rice and soybean. The plant growth promotion capacity of DK-1-1 was higher than the wild type Gibberella fujikuroi. Gibberellin (GA) analysis of culture filtrate of DK-1-1 showed the presence of higher amounts of bioactive GA 3 , GA 4 , and GA 7 (6.62, 2.1 and 1.26 ng/mL, respectively) along with physiologically inactive GA 5 , GA 15 , GA 19 , and GA 24 . Phylogenetic analysis of 18S rDNA sequence identified the fungal isolate as a new strain of Cladosporium sphaerospermum. Gibberellin production and plant growth-promoting ability of genus Cladosporium are reported for the first time in the present study.

“…Gibberellins (GAs) 1 are a family of diterpenoid plant hormones produced by the rice pathogen Gibberella fujikuroi and a few other fungal genera (Rademacher, 1997;Homann et al, 1996;Tudzynski, 1997). As they play important roles in plant growth and development there has been great interest in the analysis of this biosynthetic pathway for many years.…”
