“…The mutant was treated with uniconazole to further inhibit the GAs pathways. For providing axenic conditions, the pre-germinated waito-c and Dongjin-byeo seeds were transferred to autoclaved small plastic pots containing 0.8% water: agar medium (Khan et al 2011a(Khan et al , 2011bRedman et al 2011). After attaining two leaves stage, the CF (20 µl) harvested from endophytes was applied at the apex of rice seedlings.…”

“…The activation of suppressed GAs biosynthesis in waito-c would reveal the presence of bioactive secondary metabolites while the effects were rectified using normal rice (Khan et al 2011a(Khan et al , 2011bWaqas et al 2014). The screening results showed that CF application of endophytic strains MPB-1 and MPB-2 significantly increased the mutant and normal rice growth (Table 1).…”

“…Agar and water, on the other hand, were used as growing medium for rice. During the bioassay, the rice seeds were fully grown on agar water media till the harvest in order to accurately measure the sole effect of fungal CF (Khan et al 2011a(Khan et al , 2011b. Fusarium fujikuroi produces a wide array of diterpenoids including a group of phytohormones mainly GAs (Albermann et al 2013).…”

“…Endophytes have been mostly reported to improve plant growth (Schulz & Boyle 2005). They can influence key aspects of plant physiology and increase host plant fitness against biotic and abiotic stresses (Khan et al 2011a(Khan et al , 2011b.

Two new strains of endophytic fungi were isolated from the bark of Moringa peregrina and identified as Aspergillus caespitosus LK12 and Phoma sp. LK13. These endophytes were identified through amplifying polymerase chain reaction (PCR) and sequencing the 18S internal transcribed spacer of DNA extracted from both endophytes. Pure cultures of endophytic fungi were subjected to extract and isolate gibberellins (GAs). H 2 ]-GA 7 were used to quantify the endophytic fungal GAs. The analysis revealed that both the endophytes are producing bioactive GAs in various quantities (ng mL −1 ). A. caespitosus LK12 was producing GA 1 (54.51 ± 1.23), GA 4 (26.5 ± 0.65), and GA 7 (2.87 ± 1.23) while Phoma sp. LK13 was secreting GA 1 (4.8 ± 0.12), GA 3 (8.65 ± 0.21), GA 4 (23.7 ± 0.98), and GA 7 (22.7 ± 0.73). The culture filtrate (CF) of A. caespitosus and Phoma sp. significantly increased the shoot length of GAs-deficient mutant waito-c and normal Dongjin-beyo rice seedlings as compared to control. Application of such growth-promoting and GAs-producing endophytes can ameliorate poorly growing crop plants.
