“…B. bassiana foi descoberto naturalmente como endofíticos em diversas espécies de plantas, sendo aplicado em estudos em várias culturas, como em cultivares de café (POSADA et al, 2007), algodão (GURULINGAPPA et al, 2010), milho (BING et al, 1991), tamareira (GÓMEZ-VIDAL et al, 2006), banana (AKELLO et al, 2008, tomate (OWNLEY et al, 2008) e o feijão comum (PARSA et al, 2013), melhorando o crescimento vegetal e rendimento (CANASSA et al, 2019;GREENFIELD et al, 2016). O trabalho de Alves et al (2021), relatou um aumento na colonização micorrízica arbuscular, na massa seca de raízes e na massa total acumulada dos nutrientes P, Mn, Zn e B na parte aérea de Phaseolus vulgaris L. com a aplicação de B. Bassiana.…”

“…Fungos desse gênero têm sido estudados quanto ao potencial de prover o crescimento vegetal. Aplicações de M. Anisopliae elevaram a colonização micorrízica arbuscular, a massa seca da raiz e a massa de Fe e B acumulada na parte aérea do feijoeiro (Alves et al, 2021). Outro estudo demonstrou que o revestimento de sementes de milho com conídios de M. anisopliae reduziu a lesão das plântulas por larva-arame, influenciando no aumento de produtividade, além de melhorar o desenvolvimento de pelos radiculares em plantas jovens e elevar a biomassa das culturas (CLIFTON et al, 2018).…”

“…Trichoderma não apenas infecta outros fungos patogênicos, mas também promove o crescimento vegetal, onde sua inoculação induz tolerância ao estresse em plantas hospedeiras pelo melhor desenvolvimento da raiz e do caule, estimulo da resistência sistêmica induzida, solubilização e sequestro de nutrientes inorgânicos (SINGH et al, 2016;. O potencial como promotor do crescimento vegetal do fungo Trichoderma asperellum foi constatado na soja em condições de clima e solo de cerrado (CHAGAS et al, 2017) e em feijoeiro, em que se verificou aumento na colonização micorrízica arbuscular, na massa seca da raiz do feijoeiro (Phaseolus vulgaris), nas massas de Cu e B acumulado na parte aérea, e no carbono orgânico do solo da rizosfera com a aplicação de T. asperellum (Alves et al, 2021).…”

“…Foi observado que P. chlamydosporia consegue colonizar raízes endofiticamente de tomate (BORDALLO et al, 2002), batata (MANZANILLA-LÓPEZ et al, 2011) e cevada (MONFORT et al, 2005). Alves et al (2021) observaram aumentos da massa seca da raiz do feijoeiro, da colonização micorrízica arbuscular, na massa acumulada de Mn, Cu e Zn na parte aérea, além de aumento no pH e na concentração de cálcio e fósforo no solo devido à aplicação desse fungo.…”

Societal Impact StatementClimate change is predicted to increase drought and soil salinity in Mediterranean‐type ecosystems (MTEs), posing a significant threat to global food security. Genetic modification of crops to counteract this threat is expensive and has not met with universal support, and alternatives are hence needed to enhance crop production in MTEs. Here, fungal endophytes from the Atacama Desert, High Andes and Antarctica inoculated onto three crops were found to alleviate the negative effects of drought and salinity on plant performance. The study concludes that extremophile endophytes might be used to enhance crop performance as the climate of MTEs changes over future decades.Summary Climate change will curtail the ability to provide sufficient food for our rapidly expanding population. Improvements to crop production in changing environments, particularly Mediterranean‐type ecosystems (MTEs), which are increasingly subjected to drought and salinisation, are hence urgently needed. Here, we explored the possibility that fungal endophytes from extreme environments can be used to enhance crop yield, survival and tolerance to environmental stresses. Plants of lettuce, tomato and bell pepper were inoculated with up to six species of endophytic fungi isolated from the Atacama Desert, the High Andes and Antarctica. They were then exposed in the field for up to 120 days in each of three summers to current climatic conditions or to a future climate scenario simulating increased drought and soil salinisation. Compared with uninoculated plants, the yield and survival of inoculated crops were increased by up to two‐fold under the future climate scenario. These effects were in part attributable to the improved water balance of inoculated crops exposed to drought and salinisation. The inocula also increased the concentrations of total phenols and proline in leaves and decreased lipid peroxidation when plants were subjected to increased aridity and salinity. A mixed inoculum of six endophytes from the extreme environments conferred the most beneficial effects on crop performance, with a commercially available inoculum having fewer positive effects on crops. We conclude that the inoculation of crops with endophytes from extreme environments may be a viable solution to sustaining crop production in MTEs exposed to rapid climate change.

BACKGROUNDEntomopathogenic fungi (EPF) are multifunctional microorganisms acting not only as biopesticides against insect pests but also as endophytes which regulate plant growth. The tomato leafminer, Phthorimaea absoluta (Tuta absoluta) is a devastating invasive pest of tomatoes worldwide. However, effective alternatives are needed for a sustainable management of this invasive pest. In this study, the functional effects of five EPF isolates Metarhizium flavoviride, M. anisopliae, M. rileyi, Cordyceps fumosorosea and Beauveria bassiana were evaluated on tomato growth promotion and pest protection against P. absoluta.RESULTSWhen directly sprayed with conidia, P. absoluta larvae showed high cumulative mortality of 100% to M. anisopliae under 1 × 108 conidia/mL, whereas M. flavoviride, B. bassiana, C. fumosorosea and M. rileyi caused cumulative mortality of 92.65%, 92.62%, 92.16% and 68.95%, respectively. Moreover, all five EPF isolates can successfully colonize tomato plants, whilst the colonization rate for each EPF depends on the inoculation method used. The most efficient inoculation method for M. flavoviride and M. rileyi was root dipping, for M. anisopliae and C. fumosorosea it was coating seed, and for B. bassiana it was foliage spraying. The highest plant colonization was obtained by M. flavoviride. Meanwhile, all these isolates promoted tomato plant growth upon inoculation. Furthermore, endophytic colonization of plants by the five EPF negatively affected the performance of P. absoluta, among them M. anisopliae and C. fumosorosea showed strong negative effects on the performance of P. absoluta.CONCLUSIONOur results highlight the potential of incorporating entomopathogenic fungi as endophytes in integrated pest management practices to protect tomatoes against P. absoluta. © 2023 Society of Chemical Industry.
