Abstract

Endophytes are a potent source of bioactive compounds that mimic plant-based metabolites. Fungi Fusarium spp. and Clonostachys rosea have been identified as pathogenic microorganisms in ramie (Boehmeria nivea). The antifungal test was carried out using the diffusion method and the MIC50 and Minimum Fungicidal Concentration (MFC) values using the tested microbial pathogens were Fusarium solani isolate 3248941, F. solani isolate Colpat-359, F. oxysporum isolate N-61-2, dan Clonostachys rosea strain B3042. Identification of secondary metabolites of the extract was carried out using GC-MS. The chromatogram of GC-MS analysis of this ethyl acetate extract (EA) showed seven dominant chemical compounds with various biological activities. Ethyl asetate extract of P. citrinum showed inhibition zone ranged from 19.10–22.07 mm with strong-very strong category at 200 mg ml-1 concentration against the tested microbial pathogens. Results revealed that the significant MIC values were observed against F. solani isolate 3248941 and Clonostachys rosea strain B3042 by less than 6.3  mg ml-1 and against F. solani isolate Colpat-359 and F. oxysporum isolate N-61-2 with 12.5 mg ml-1 and 25 mg ml-1 respectively. Minimum Fungicidal concentrations (MFC) for EA of P. citrinum were also reported against F. solani isolate 3248941 and C. rosea strain B3042, by 12.5 mg ml-1, whilst Fusarium solani isolate Colpat-359 by 25 mg ml-1 and Fusarium oxysporum isolate N-61-2 ,by 50 mg ml-1 respectively. Results of this study showed that P. citrinum, endophytic fungi of ramie, could be a promising source of compounds for antifungal agents.

Abstract

Xanthomonas oryzae which causes bacterial leaf blight disease is one of the main pathogens that attack rice crops. The threat of losing rice yields due to X. oryzae needs to be avoided by implementing appropriate control strategies. Sonic bloom has the potential to induce plant immunity against diseases. Hence, this study aimed to examine the potential of sonic bloom in inducing rice resistance to bacterial leaf blight. The experiment was arranged in a Randomized Block Design (RBD) with five treatments and three replications. The treatments consisted of several frequencies, namely PR (0.5 - 1 kHz and inoculated with X. oryzae), PS (3 - 5 kHz and inoculated with X. oryzae), PT (7 - 10 kHz and inoculated with X. oryzae), KP (inoculated with X. oryzae without sonic bloom treatment), KN (no bacterial inoculation and sonic bloom treatment). The results showed that all sonic bloom treatments (LF, MF, HF) had a significant effect on increasing the intensity of BLB disease in rice plants. This showed that sonic bloom in this range does not have the potential to induce rice plant resistance to BLB. Further research to find out the causes of this is needed.
