“…Our findings offered more detail insight into the colonization process. In addition to direct observation of fungal colonization, molecular detection is another effective means to verify that endophytic fungi colonize plants [ 63 , 64 ]. Our sequenced data verified the endophytic isolate as I. cateniannula , colonized in the buckwheat sprouts at 24 h.…”

The use of entomogenous fungi as endophytes is currently an area of active research. Isaria cateniannulata is an important entomogenous fungus that has been employed for the active control of a range of pests in agricultural and forestry settings, but its direct impact on plants remains to be evaluated. Herein, we assessed the ability of I. cateniannulata to colonize buckwheat, Fagopyrum esculentum and F. tataricum, and its impact on buckwheat defense enzyme activity and physiological indexes. The majority of fungal submerge condia was able to enter into leaves through stomata and veins, and this was followed by conidial attachment, lytic enzyme secretion, conidial deformation, and enhanced defensive enzyme activity within buckwheat, followed by the repair of damaged tissue structures. I. cateniannulata populations on buckwheat leaf surfaces (in CFU/g) reached the minimum values at 24 h after inoculation. At this time, the blast analysis revealed that the sequence identity values were 100%, which was consistent with the sequence of I. cateniannula. The number of I. cateniannulata submerge conidia colonized in the buckwheat leaves gradually rose to peak levels on 7 d post-inoculation, and then gradually declined until 10 d, at which time the buckwheat plant growth index values increased. This study provided novel evidence that I. cateniannulata could be leveraged as an endophytic fungus capable of colonizing buckwheat plants and promoting their growth.

“…Secara mikroskopis jamur Phyllosticta sp. memiliki hifa bersekat, tidak berwarna (hialin), konidia berbentuk oval, tidak berwarna (hialin) dan bersekat (Istikorini & Sari, 2022). Isolat EA2 secara makroskopis memiliki koloni berwarna hijau keabuan pinngiran putih, pada awal pertumbuhan berwarna putih semakin tua masa pertumbuhan warnanya menjadi hijau pekat, tesktur koloninya seperti kapas dan bentuk koloninya bersemak.…”

Shallot (Allium ascalonicum L.) is a horticultural commodity that has high economic value and is needed every day by the community. Attack by pets and pathogens on shallot cultivation cause a decrease in crop productivity. The pathogen that often attacks shallot plants is Fusariumsp. and Alternaria sp. This study aims to obtain endophytic fungi from shallot leaves that can control Fusarium sp. and Alternaria sp. The endophytic fungus isolation method uses healthy shallot leek samples while the pathogen isolation uses unhealthy leaves. The antagonism potency test was conducted using the dual culture method with an incubation time of 7 days at 25-30oC. Based on the results of the study, there were 4 isolates of endophytic fungi on shallot leaves, namely EA1 isolates (Aspergillus niger), EA2 isolates, EA3 isolates (Clasdoporium sp.) and EA4 isolates (Phyllosticta sp.). The results of the antagonist test showed that the endophytic fungus EA1 was able to inhibit the fungus Fusarium sp. and Alternaria sp. maximally (strong) with an average value of Fusarium sp. of 62.72% while Alternaria sp. 67.83 %. The endophytic fungus EA2 was also able to inhibit both of these pathogens but it was moderately categorized with an average value of Fusarium sp. 52.11 % and Alternaria sp. 53.28%. The mechanisms of inhibition are competition and hyperparasitism.

“…S. balangeran develops adventitious roots to adapt to flooded conditions (Tata et al 2022). The presence of nine types of endophytic molds on the leaves and twigs of S. balangeran also helps it control pests and diseases naturally (Istikorini and Sari 2022). Shorea balangeran is naturally distributed in tidal areas and swamps on the islands of Sumatra and Kalimantan, namely in Bangka Belitung, West Kalimantan, South Kalimantan, and Central Kalimantan (Arsad 2016;Suryanto et al 2012).…”

The success of peat swamp ecosystem restoration needs to be supported by the supply of good quality native plant species, one of which is influenced by the growing media. This study aimed to evaluate the effect of cocopeat, compost, and biochar as a mixture of peat media on the growth of Dyera polyphylla and Shorea balangeran seedlings in a greenhouse for six months. The experiment was carried out using a completely randomized design with one factor, growing media (100% peat as M1 (control); 70% peat + 30% cocopeat as M2; 70% peat + 30% compost as M3; and 70% peat + biochar 30% as M4). The survival rate of both types of seedlings in all growing media treatments was 100%. Dickson Quality Index (DQI) of D. polyphylla seedlings on M1, M2, M3, and M4 was 0.32, 0.29, 0.46, and 0.31, respectively, and for S. balangeran was 0.15, 0.10, 0.09, and 0.12, respectively. Adding cocopeat, compost, and biochar could increase the nutrient content of peat media. The growing media with the best quality for D. polyphylla was M3, while for S. balangeran was M1.
