“…Cochliobolus lunatus have capacity to degrade crude oil by 4.7% (Al-Nasrawi, 2012 ). The results of studies with Curvularia geniculata P1 help to understand the regulatory mechanisms of mercury tolerance and plant growth, C. geniculata P1 increase the host plant Oryza sativa L. biomass by four-fold and reduce the negative impacts of the metal on photosynthesis, several gene clusters are also involved to regulate these processes (de Siqueira et al, 2021 ). Pietro-Souza et al ( 2020 ) did mercury bioremediation experiment, results revealed that Curvularia geniculata P1 removes 100% mercury from the cultures via the mechanism of volatilization and bioaccumulation.…”

Many filamentous fungi are known to produce several secondary metabolites or bioactive compounds during their growth and reproduction with sort of various biological activities. Genus Curvularia (Pleosporaceae) is a dematiaceous filamentous fungus that exhibits a facultative pathogenic and endophytic lifestyle. It contains ~213 species among which Curvularia lunata, C. geniculata, C. clavata, C. pallescens, and C. andropogonis are well-known. Among them, C. lunata is a major pathogenic species of various economical important crops especially cereals of tropical regions while other species like C. geniculata is of endophytic nature with numerous bioactive compounds. Curvularia species contain several diverse groups of secondary metabolites including alkaloids, terpenes, polyketides, and quinones. Which possess various biological activities including anti-cancer, anti-inflammatory, anti-microbial, anti-oxidant, and phytotoxicity. Several genes and gene factors are involved to carry and regulate the expression of these activities which are influenced by environmental signals. Some species of Curvularia also show negative impacts on humans and animals. Apart from their negative effects, there are some beneficial implications like production of enzymes of industrial value, bioherbicides, and source of nanoparticles is reported. Many researchers are working on these aspects all over the world but there is no review in literature which provides significant understanding about these all aspects. Thus, this review will provide significant information about secondary metabolic diversity, their biological activities and biotechnological implications of Curvularia species.
