Beauveria bassiana : An entomopathogenic fungus alleviates Fe chlorosis symptoms in plants grown on calcareous substrates

Soil Nutrients Effects on the Performance of Durum Wheat Inoculated with Entomopathogenic Fungi

“…This could explain the temporal reduction in plant height (at 39 DAS for B. bassiana; Figure S1) and the number of tillers (Table 2) relative to the Control plants in the first phenological stages but not at harvest (no significant reduction in ADM or grain yield). This negative initial effect or cost of fungal inoculation on plant growth was also observed by other authors [10,12,13] and could have been caused by the activation of the defensive mechanism of the host plants [34]. Consistent with this last claim, the increase in grain yield was related to Mn, a key nutrient in the plant immune system [35,36].…”

“…Plant growth rate, as the increase in plant height over time, was measured at 13,19,26,39,48 and 73 DAS. The gas exchange parameters [viz., photosynthesis rate (A n ), conductance (g s ), intercellular CO 2 concentration (C i ) and transpiration rate] were measured in wheat plants grown on five randomly selected soils (No.…”

“…Success in the mutualistic relationship between EF and wheat plants depends on the fungal strain and soil properties. been investigated as plant growth promoters [10-12] and nutritional enhancers [10,[13][14][15][16]. Although B. bassiana, M. brunneum or both fulfill the expectations of most studies, these studies were largely conducted under conditions far from typical field settings.…”

“…Although B. bassiana, M. brunneum or both fulfill the expectations of most studies, these studies were largely conducted under conditions far from typical field settings. In fact, a number of studies were performed on sterile soils or artificial substrates; the effects of the fungi were only examined during early crop growth stages [10,11,13], so neither potential interactions with crops grown on natural soils nor their effects throughout the crop cycle were considered. In addition, although some physical soil properties are known to affect the availability, mobility and virulence of EF conidia in soil [17], there is a knowledge gap on the role that physical and chemical soil properties play in the crosstalk between EF and plants.…”

Comparison of wheat growth-response to endophytic Beauveria bassiana (Hypocreales: Cordycipitaceae) derived from an insect versus plant host

“…However, the ubiquitous nature of this EPF within global agro-ecosystems, makes it suitable for exploitation in Conservation Biological Control (CBC) (Fuxa, 1998), as proposed by Meyling and Eilenberg (2007). Therefore, the notion of exploiting B. bassiana in a CBC approach carries relevance, not only in terms of insect suppression, but potentially for disease suppression (Busby et al, 2016) and also as a plant growth-promoting factor (Behie and Bidochka, 2014;Sánchez-Rodríguez et al, 2015;Liao et al, 2017;Jaber and Enkerli, 2017;Sánchez-Rodríguez et al, 2018). In nature, insect-derived inoculum is the primary source of B. bassiana, while the historical frequency of recycling remains largely unknown.…”
