“…Non-pathogenic root colonizing fungi and their microbial metabolites have also shown to induce systemic resistance (ISR) as well against pathogens and insect herbivores. Plant growth promoting fungi (PGPF) are one such group that stimulates plant growth and yield of various crops (Hossain et al 2008 , 2014 ; Islam et al 2014a , b ). A wide variety of root-associated mutualistic fungi including species belonging to the genera Trichoderma , Fusarium , Penicillium , Phoma , Aspergillus and sterile fungi are reported to be PGPF (Koike et al 2001 ; Hyakumachi and Kubota 2004 ; Hossain et al 2008 , 2014 ; Sultana et al 2008 ; Horinouchi et al 2011 ; Islam et al 2014a , b ).…”

The PGPF isolate P. simplicissimum GP17-2 effectively controlled soil-borne diseases (Hyakumachi 1994 ) and also has been shown to induce systemic defense responses in cucumber plants against several diseases when applied as cell free filtrate (CF) (Shivanna et al 1996 ; Koike et al 2001 ).…”

In Arabidopsis thaliana, significant efforts to determine the effect of naturally occurring variation between phenotypically divergent accessions on different biotic or abiotic stresses are underway. Although it is usually assumed that induced systemic resistance (ISR) against pathogen will covary with plant genetic variation, this assumption has not been tested rigorously in previous experiments. Here, we investigated heritable variation in resistance as well as Penicillium simplicissimum GP17-2-mediated ISR to the bacteria Pseudomonas syringae pv. tomato DC3000 (Pst) among a worldwide collection of accessions of A. thaliana. In this study, 75 Arabidopsis accessions were screened against the bacteria Pst following induction and non-induction treatment and their resistance levels were determined by measuring three components of A. thaliana resistance (infected leaf number, disease severity and pathogen growth). We observed extensive quantitative variation in the number of infected leaves, severity of disease symptoms and the bacterial population size among 75 accessions of A. thaliana infected with Pst. On the contrary, about a two-third of the accessions (49 accessions) showed a reduction in infected leaf number, disease severity and pathogen proliferation after treatment with GP17-2, indicating that GP17-2 induction of resistance is ecotype specific in Arabidopsis. The level of suppression was more pronounced for percent disease severity and pathogen proliferation than for number of infected leaves in ISR-inducible accessions. Accessions non-responsive to GP17-2 treatment generally appeared to be associated with higher basal resistance to infection by Pst. Future study with these parental lines employing a variety of crossing schemes may facilitate identification of major trait loci responsible for GP17-2-mediated ISR in Arabidopsis.

The culturable endophytic fungal communities of switchgrass grown on a coal-mining site and their effects on plant growth

Plants have a diverse endophytic microbiome that is functionally important for their growth, development, and health. In this study, the diversity and specificity of culturable endophytic fungal communities were explored in one of the most important biofuel crops, switchgrass plants (Panicum virgatum L.), which have been cultivated on a reclaimed coal-mining site for more than 20 years. The endophytic fungi were isolated from the surface-sterilized shoot (leaf and stem), root, and seed tissues of switchgrass plants and then cultured for identification. A total of 1339 fungal isolates were found and 22 operational taxonomic units (OTUs) were sequence identified by internal transcribed spacer (ITS) primers and grouped into 7 orders and 4 classes. Although a diverse range of endophytic fungi associated with switchgrass were documented, the most abundant class, order, and species were Sordariomycetes, Hypocreales, and Fusarium spp. respectively. About 86% of the isolated endophytic fungi were able to enhance the heights of the shoots; 69% could increase the shoot fresh weights; and 62% could improve the shoot dry weights after being reintroduced back into the switchgrass plants, which illustrated their functional importance. Through the Shannon Diversity Index analysis, we observed a gradation of species diversity, with shoots and roots having the similar values and seeds having a lesser value. It was observed that the switchgrass plants showing better growth performance displayed higher endophytic fungal species diversity and abundance. It was also discovered that the rhizosphere soil organic matter content was positively correlated with the fungal species diversity. All these data demonstrate the functional association of these beneficial endophytic fungi with switchgrass and their great potential in improving the switchgrass growth and biomass to benefit the biofuel industry by reducing chemical inputs and burden to the environment.

“…Significantly, higher germination and vigor index were observed in Indian spinach, when seeds were sown in sterilized field soil amended with wheat grain inoculum of Fusarium spp. PPF1 [27]. Sphaerodes mycoparasitica, a biotrophic mycoparasite of Fusarium species, improved wheat seed germination and seedling growth in vitro compared to T. harzianum, while under phytotron conditions, both S. mycoparasitica and T. harzianum had positive impact on wheat seedlings growth in the presence of F. graminearum [12].…”

“…Different species of Aspergillus are known to support shoot growth in chickpea [16], Chinese cabbage [56], cucumber [17], soybean [18,65] and wheat [76]. Species of nonpathogenic Fusarium were reported to stimulate shoot growth in Indian spinach [27] and banana [29]. Application of barley grain inoculum of Penicillium viridicatum GP15-1 to the potting medium resulted in 26-42% increase in stem length, 37-46% increase in shoot fresh weight and 100-176% increase in shoot dry weight of cucumber plants [35].…”

Plant growth-promoting fungi (PGPF) constitute diverse genera of nonpathogenic fungi that provide a variety of benefits to their host plants. PGPF show an effective role in sustainable agriculture. Meeting increasing demand for crop production without damage to the environment is the biggest challenge nowadays. The use of PGPF has been recognized as an environmentally friendly way of increasing crop production. These fungi have proven to increase crop yields by improving germination, seedling vigor, plant growth, root morphogenesis, photosynthesis, and flowering through either a direct or indirect mechanism. The mechanisms of PGPF involve solubilizing and mineralizing nutrients for easy uptake by plants, regulating hormonal balance, producing volatile organic compounds and microbial enzyme, suppressing plant pathogens and ameliorating abiotic stresses. Successful colonization is an intrinsic factor for most PGPF to exert their beneficial effects on plants. A certain level of specificity exists in the interactions between plant species and PGPF for root colonization and growth promoting effects. There is a gap between the number of reported efficacious PGPF and the number of PGPF as biofertilizer. Efforts should be strengthened to improve the efficacy and commercialization of PGPF. Hence, this chapter summarizes valuable information regarding the application and mechanisms of PGPF in sustainable agriculture.
