“…The findings of this research agree with the report by Eo & Eom (2009) on some vegetable plants and Lu & Wu (2017) on white clover (Trifolium repens) where plants inoculated with AMF showed higher biomass increment. Hoeksema et al (2010) reported that plants colonised by AMF grew larger than those without AMF.…”

“…The amount of P in the potting medium used in the study was not controlled as the soil was collected from an agricultural field. The source of AMF inoculum added to T2 was from a disturbed forest thus the possibilities that environmental conditions, such as variation in soil P, may have influenced the diversity of AMF taxa causing differences in response by the host plants (Eo & Eom, 2009). Goss et al (2017) also highlighted the impact of past cultural practices that can influence mycorrhizal colonisation.…”

Terung asam (Solanum lasiocarpum Dunal) is a native fruit vegetable that is gaining interest as a commercial crop in Sarawak and Malaysia. Malaysia is covered by soils that are highly weathered, acidic, and low in fertility and depend on chemical fertilisers to promote good plant growth. Alternative means to reduce dependency on chemical fertiliser, for example arbuscular mycorrhiza fungi (AMF), must be sourced. Very few research on terung asam has been documented particularly on nutrients uptake. The objectives of this research were to investigate the effect of indigenous and non-indigenous AMF on nutrient uptake by terung asam. A greenhouse experiment was conducted consisting of three treatments namely control (T1), indigenous AMF (T2), non-indigenous AMF (T3). The treatments were arranged in a complete randomised design with four subsamples and four replicates. Thirty-day-old seedlings were transplanted and measured for their heights and stem diameters for 90 days. Fresh and dry shoot and root weights were taken during harvesting. Plant nutrient analyses were conducted using Kjeldahl method for total N, single ashing for P and single ashing and double acid for K, Ca and Mg. The results revealed the addition of AMF spores at 200 spores per pot, increased plant height by 13 to 33% and stem diameter by 5 to 25% and more leaves were retained by T3 plants at harvesting. T3 recorded higher fresh shoot (11.27%) and dry shoot (14.98%) as well as fresh root (23.67%) and dry root (22.77%) weights than T1 plants. Addition of AMF in treatments T2 and T3 promoted better nutrient uptake by aboveground and belowground biomasses particularly for K, Ca and Mg. T3 was superior in terms of the nutrient uptake for most nutrients. AMF used in T3 showed better results as the AMF spores were proven effective in promoting plant growth while AMF used in T2 were obtained from the field and untested. The findings of this study showed the potential of indigenous and non-indigenous AMF in promoting growth and nutrient uptake by terung asam plants.

“…This was not the case here when legumes were the AM host. While several crop species, including cereals (Zhang et al 2019), generally respond positively to inoculation with AM fungi, this is often less so for cereals (Eo and Eom 2009). Indeed, cereal responses to AM fungi are generally positive but weak, highly crop-specific, and tend to be negative for crops released after the 1950s (Zhang et al 2019).…”

Arbuscular mycorrhizal (AM) fungi, a group of widespread fungal symbionts of crops, could be important in driving crop yield across crop rotations through plant–soil feedbacks (PSF). However, whether preceding crops have a legacy effect on the AM fungi of the subsequent crop is poorly known. We set up an outdoor mesocosm crop rotation experiment that consisted of a first phase growing either one of four pre‐crops establishing AM and/or rhizobial symbiosis or not (spring barley, faba bean, lupine, canola), followed by an AM crop, winter barley. After the pre‐crop harvest, carbon‐rich organic substrates were applied to test whether it attenuated, accentuated or modified the effect of pre‐crops. The pre‐crop mycorrhizal status, but not its rhizobial status, affected the richness and composition of AM fungi, and this difference, in particular community composition, persisted and increased in the roots of winter barley. The effect of a pre‐crop was driven by its single symbiotic group, not its mixed symbiotic group and/or by a crop‐species‐specific effect. This demonstrates that the pre‐crop symbiotic group has lasting legacy effects on the AM fungal communities and may steer the AM fungal community succession across rotation phases. This effect was accentuated by sawdust amendment, but not wheat straw. Based on the previous observation of decreased crop yield after AM pre‐crops, our findings suggest negative PSF at the level of the plant symbiotic group driven by a legacy effect of crop rotation history on AM fungal communities, and that a focus on crop symbiotic group offers additional understanding of PSF.

Recently, both domestic and foreign ginseng growers have begun to focus on sustainable production and clean technology, with a concurrent increase in the use of various helpful fungi for organic and clean farming [ 11 , 12 ].…”

We investigated the diversity of the foliar endophytes of Korean ginseng. Endophytic fungi were isolated from healthy leaves of mountain-cultivated ginseng (MCG) and field-cultivated ginseng (FCG) at 4 sites in Chungbuk Province. A total of 24 species of fungal endophytes were identified using molecular approaches. Additionally, the diversity of these endophytic fungi was compared between MCG and FCG. The major isolated endophytes were Edenia gomezpompae and Gibberella moniliformis in the MCG and FCG samples, respectively. The results suggest that ginseng endophytes have different community structures in different environments, and this understanding may prove useful in ginseng cultivation.
