A Study of Plant Growth Promoting Diversity of Fungi

Plant growth-promoting fungi (PGPF) have attracted considerable interest as bio-fertilisers due to their multiple beneficial effects on plant quantity and quality and their positive relationship with the ecological environment. Progress has been made towards PGPF production for crops and economic crops, but such changes for PGPF use with common medicinal herbs, such as Salvia miltiorrhiza, are uncommon. Waito-C rice (WR) seedling for plant growth-promoting verification was handled with Fungal culture filtrates (FCF). The Sj-2-2 fungal strain has been reported to promote plant growth (PGP) in WR. Then, Sj-2-2 culture filtrate treatment confirmed PGP from Suaeda japonica. Consequently, it has been reported that Sj-2-2 culture filtrate is better than positive control in S. Japanese. HPLC analysis and GC-MS SIM analysis identified the secondary metabolites involved in cultivation filtrate of Sj-2-2. It was detected that the Sj-2-2 culture was filtered with the presence of physiologically bioactive gibberellins (GAs) and other inactive GA. The similitude to penicillussp was shown in the molecular sequence study of Sja-2-2 of homology of 99 percent. The PGP of Sj-2-2 was reported, along with the symbiosis among endophytic fungi and the halophytes naturally cultivated in salt marsh. Sj-2-2 has been identified by molecular sequence analysis as a new fungal strain generating GAs. Therefore, Penicilliumsp was referred to as the Sj-2-2 fungal strain. D-2-2. D-2. The study confirmed the diversity and the PGP of the new gibberellin-producing fungal strain isolated from the roots of halophytes in marsh salt.
