“…The endophytic fungi of Potentilla fulgensis is reported to have the metabolic machinery to secrete plant growth hormones such as cytokinins, auxins and gibberellins which promote seed germination and growth (Bhagobaty & Joshi 2009). Khan et al (2015) reported that two fungal endophytes, Fusarium and Alternaria isolated from the leaves of Solanumnigrum, increased the chlorophyll content, root-shoot length, and biomass production of Dongjin rice plantswhen inoculated at the seedling stage. Gas chromatography/ mass spectrometry analysis for the culture filtrates of each fungal endophytic isolate revealed that both Fusarium and Alternaria could produce 54 and 30 µ.gm.L -1 of indole acetic acid, respectively.…”

Use of chemical fertilizers and pesticides in rice cultivation has incurred many environmental and health problems in Sri Lanka. Therefore, there is renewed interest in cultivating traditional rice varieties as they are more amenable to organic farming practices. However, as the yield of these varieties is comparatively low, strategies to enhance their performance should be investigated. As endophytes of plants are reported to promote growth and yield of a number of crop varieties, this study was aimed at studying the endophytic fungal assemblage present in the traditional rice variety Kuruluthuda with a view to evaluate their capacity to enhance plant growth and yield. Twenty seven endophytic fungal species were isolated from different parts of Kuruluthuda rice plants collected from a paddy field cultivated using organic fertilizers in the Gampaha district, Sri Lanka. Two frequently isolated endophytic fungal spp. i.e. Acremonium and Arthrobotrys (frequencies of isolation 60% and 38.6% respectively) were introduced separately and in combination torice seedlings using spore suspension and plate methods to determine their effect on growth and yield under green house and field conditions. All endophyte inoculated plants showed a significant difference (P ≤ 0.05) in plant growth (height, fresh weight and dry weight), number of tillers and yield when compared withnon-inoculated plant sunder both green house and field conditions. The effect of Acremonium and Arthrobotrys when introduced in combination showed a significant difference (P ≤ 0.05) in the fresh weight, dry weight, tiller number and yield (weight of seeds harvested) when compared to their individual effects under field conditions which indicates that the two endophytes in combination can be used as a better inoculum to improve biomass and yield of the plants of rice variety tested. This is the first report of the endophytic mycoflora of the rice variety Kuruluthuda and their potential use for growth promotion and yield enhancement.

“…However, the exploration of endophytic fungi as biocontrol agents against this disease is rarely considered (Kavroulakis et al, 2007). Interestingly, some wild Solanum species have been explored as potential sources of bioactive molecules and biocontrol agents (Khan et al, 2015;Aydi Ben Abdallah et al, 2016). In the present study, a collection of fungal isolates naturally associated with S. linnaeanum was screened for its ability to suppress FCRR and to promote tomato growth when applied as conidial suspensions or cell-free culture filtrates.…”

Fusarium crown and root rot (FCRR) is a serious tomato disease in Tunisia which is difficult to control due to its soilborne nature and to the luck of genetic resistance. In the current study, native Solanum linnaeanum was explored as potential source of effective fungal agents for disease biocontrol. Eight fungal isolates, recovered from S. linnaeanum plants growing in the Tunisian Centre-East and shown able to colonize roots, crowns and stems of tomato (Solanum lycopersicum L.) seedlings, were tested for their ability to inhibit Fusarium oxysporum f. sp. radicis-lycopersici (FORL), the causal agent of this disease, and to promote plant growth. Tomato seedlings inoculated or not with FORL and treated using tested fungal isolates, exhibited significant increments in their growth parameters. Tested as conidial suspensions or cell-free culture filtrates, I74 and I92 isolates were the most active leading to 92.8% decrease in FCRR severity and 89.3 to 95.2% lowered vascular browning extent as compared to FORLinoculated and untreated controls. These two isolates were microscopically and macroscopically described and identified using rDNA sequencing gene as being Penicillium crustosum I74 (MF188258) and Fusarium proliferatum I92 (MF188256). Pathogen mycelial growth was inhibited by 29.4 to 78.1% using their conidial suspensions and by 67.5 to 82% with their cell-free culture filtrates. P. crustosum I74 and F. proliferatum I92 showed chitinolytic, proteolytic and amylase activities. Only I92 isolate exhibited a lipolytic activity. Our study clearly demonstrated that I74 and I92 isolates were promising candidates for suppressing FCRR severity and promoting tomato growth. Further investigations are required for elucidating their mechanisms of action involved in disease suppression and plant growth promotion.
