“…In Western Europe the breeding period lasts from April to June while at the Mediterranean multiple copulations and ovipositions within one reproduction period may occur and last from October to December and February to April ( Nicolai et al., 2005 ). Important triggers of egg oviposition in lymnaea stagnalis pond snails were oxygen - rich clear water, water quality and light ( Ter Maat et al., 2012 ; El-Sayed et al., 2020 ). Oviposition period of E. vermiculata was averaged from 15 to 25 days ( Mohamed and Ali 2009 ).…”

“…This species is characterized by its survival capacities and has been introduced by human activities to numerous countries from the United States to Japan ( Ueshima et al., 2004 ; Ronsmans and Van den Neucker 2016 ). E. vermiculata forayed many Egyptian agricultural fields ( El-Sayed, 2013 ; El-Sayed et al., 2018 ; 2019a ; c , 2020 ). Their highest population densities on citrus trees at Sharkia Governorate were detected during spring while the highest vertical distribution on Casuarina trees was noticed during summer ( Ismail et al., 2017 ).…”

“…The high expense and resistance exerted against synthetic pesticides encouraged the usage of naturally derived compounds in pests control managements ( Ali et al., 2015 ; Massoud and Habib 2003 ). Nowadays, many countries have supported the usage of natural plant products and microbial pesticides due to their low mammalian toxicity, low costs and fast biodegradability ( El-Sayed et al., 2020 ; El-Sayed and Ali, 2020 ; El-Sayed et al., 2018 , 2019a , c ; Singh et al., 2000 ; Genena and Mostafa, 2008 ; Abd El-Atti et al., 2020 ). Few studies have been carried out addressing the effect of hormones on reproduction of basommatophoran pulmonates snails and slugs but much fewer studies have done on stylommatophoran land snails ( Kruatrachue et al., 1996 ).…”

“…Endophytes are microorganisms which colonize the internal tissues of plants without causing any harmful effects on their host plants. Endophytic fungi exert uncountable protective effects on plants through their interactions, stimulating the production of important secondary metabolites, that could have both significant positive and negative influences on human health [ 97 ]. Some of these microorganisms produce natural products with effective uses in agriculture, medicine and industry [ 98 ].…”

Endophytic fungi have been considered as a repertoire for bioactive secondary metabolites with potential application in medicine, agriculture and food industry. The biosynthetic pathways by fungal endophytes raise the argument of acquisition of these machineries of such complex metabolites from the plant host. Diterpenoids “Taxol” is the most effective anticancer drug with highest annual sale, since its discovery in 1970 from the Pacific yew tree, Taxus brevifolia. However, the lower yield of Taxol from this natural source (bark of T. brevifolia), availability and vulnerability of this plant to unpredicted fluctuation with the ecological and environmental conditions are the challenges. Endophytic fungi from Taxus spp. opened a new avenue for industrial Taxol production due to their fast growth, cost effectiveness, independence on climatic changes, feasibility of genetic manipulation. However, the anticipation of endophytic fungi for industrial Taxol production has been challenged by the loss of its productivity, due to the metabolic reprograming of cells, downregulating the expression of its encoding genes with subculturing and storage. Thus, the objectives of this review were to (1) Nominate the endophytic fungal isolates with the Taxol producing potency from Taxaceae and Podocarpaceae; (2) Emphasize the different approaches such as molecular manipulation, cultural optimization, co-cultivation for enhancing the Taxol productivities; (3) Accentuate the genome mining of the rate-limiting enzymes for rapid screening the Taxol biosynthetic machinery; (4) Triggering the silenced rate-limiting genes and transcriptional factors to activates the biosynthetic gene cluster of Taxol.

“…In this study, to investigate an effective insecticide against S. littoralis, 15 different medicinal plants were chosen, and their potential endophytic fungi have been isolated, and their insecticidal activity were resolved. 45 isolates were collected from these plants, Sarocladium strictum, endophyte of Cynancum acutum, and Aspergillus nidulans, endophyte of Lantana camara, exhibited the maximum insecticidal activity versus 2nd larval instar of S. littoralis (El-Sayed et al 2020).…”

Plant endophytes are a potential source for the production of bioactive compounds that can fight against devastating diseases in both plants and humans. Among these endophytic microorganisms, endophytic fungi are one of the dominant group of microorganisms with a potential role in plant growth promotion and the discovery of noble bioactive natural products. Endophytic fungi possess several bioactivities like anticancer, antimicrobial, anti-rheumatoidal, insecticidal, plant growth stimulants, crop protection, phytoremediation, etc. In 2010, Abdel-Azeem mentioned endophytic fungi as a group needing more exploration in Egypt among the other overlooked fungal groups such as algicolous fungi, invertebrate associated fungi, mycorrhizas, lichens, wood deteriorating, and coprophilous fungi. Presently, main target of many studies in Egypt on endophytic fungal research is coupled with the ability of these microorganisms to produce and accumulate novel bioactive metabolites as these are potent source of novel natural products useful for anticancer, anti-rheumatoid, antimicrobial, antioxidants, industrial and pharmaceutical enzymes…etc. This mini-review illustrates the role of most brilliant Egyptian researchers to generate potentially valuable products by using native endophytic fungi and the present status of endophytic fungal research in Egypt.
