Importance and distribution
Biochemical importance of the genus, chemical diversity or applications
Roussoella produces a wide range of chemicals. Compounds reported from Roussoella include Roussoellols A and B which are Tetracyclic Fusicoccanes from R. hysterioides (Takekawa et al. 2013), Roussoellatide, Dichlorinated Polyketide from the marine-derived Roussoella sp. DLM33 (Ferreira et al. 2015), two natural products epoxyroussoenone and epoxyroussoe-dione from a culture broth of R. japanensis KT1651 (Honmura et al. 2015), biofilm inhibitory Abscisic Acid Derivatives from Roussoella sp. on plant in terrestrial habitats (Phukhamsakda et al. 2018), Roussoelins A and B: two phenols exhibiting antioxidant activity from ascidian-derived taxon R. siamensis SYSU-MS4723 (Chen et al. 2021), 2-Oxaspiro [4.5] decane and α-pyrenocine derivatives from endophytic Roussoella sp. PSU-H51 (Sommart et al. 2021) and fusicoccan dehydroxypericonicin A (Hayasaka et al. 2021).
There are 45 Roussoella epithets in Index Fungorum (2022), but several species have been transferred to Neoroussoella, Pararoussoella, Parathyridaria, Phyllachora, Pseudoneoconiothyrium, Pseudoroussoella, Pseudothis, Systremma and Thyridaria. Roussoella comprises 33 species known on a wide range of plants such as Arundinaria hindsii (Poaceae), Bambusa sp. (Poaceae), Calamus sp. (Acoraceae), Dendrocalamus pulverulentus (Poaceae), parasitic on Didymosphaeria striatula, Elaeis guineensis (Arecaceae), Fargesia yunnanensis (Poaceae), Gigantochloa scribneriana (Poaceae), Indocalamus sinicus (Poaceae), Licuala sp. (Arecaceae), Neosinocalamus affinis (Poaceae), Pennisetum purpurascens (Poaceae), Phyllostachys sp. (Poaceae), Sasa kurilensis (Poaceae), Schizostachyum sp. (Poaceae), Yushania niitakayamensis (Poaceae) and Zingiber sp. (Zingiberaceae). Roussoella has wide distribution such as Africa (Gabon), Asia (Brunei, China, Indonesia, Hong Kong, India, Japan, Malaysia, Philippines, Thailand), Caribbean (Cuba), Europe (France) and South America (Brazil). Roussoella percutanea is an opportunistic pathogen causing subcutaneous mycoses (Ahmed et al. 2014).
