Trichoderma asiaticum is a species of fungus described in 2021 by Zheng et al. It was isolated from environmental samples and characterized using morphological features and molecular phylogenetic analyses.[1] Tricoderma sp. have a wide distribution and several novel species have been described from soils in China.[2] No T. asiaticum-specific economic uses have been reported. However, species of the genus Trichoderma are widely used in agriculture as biocontrol agents and in industrial applications.
Taxonomy and genetics
Taxonomy
Trichoderma asiaticum is a species of filamentous fungus in the family Hypocreaceae, order Hypocreales, within the phylum Ascomycota. It was formally described in 2021 based on morphological characteristics and molecular phylogenetic analyses using gene regions such as rpb2 and tef1.[2] The type specimen was discovered in the soil of a tobacco rhizosphere in Luliang county, Yunnan province, China (中国云南省 陆良县) at the following coordinates: 24°57'22.0"N 103°46'30.0"E / 48 R 376335.62 2760645.83. [1]
The genus Trichoderma comprises numerous species commonly found in soil and plant-associated environments, with species boundaries increasingly resolved through molecular methods rather than morphology alone.[2]
Genetics
Trichoderma asiaticum is likely primarily asexual. As in other Trichoderma species, genetic variation arises through mutation and parasexual processes.
Morphology
Trichoderma asiaticum produces colonies that vary in appearance depending on culture medium. After 7 days at 25 °C, colonies grown on CMD, PDA, and SNA exhibit distinct growth forms and coloration.[1] Conidiophores are formed on SNA and are branched, bearing phialides that give rise to conidia. Phialides are arranged along the conidiophores and produce conidia in clusters.[1] Conidia are smooth-walled and typically globose to subglobose in shape.[1]
Commercial Uses
Currently Trichoderma asiaticum does not have any described commercial uses, such as a fungicide, or biofertilizer. However, many species in the genus Trichoderma are used as microbial biological control agents (MBCA) in integrated pest management (IPM) systems.[3] In practice, Trichoderma can be applied to the seed or propagation material at the time of propagation. A secondary use is while the plant is growing. The primary function is to control soilborne fungal pathogens such as Rhizoctonia, Pythium and Sclerotinia. Additionally it has been shown to aid in mitigating foliar pathogens such as Botrytis and Alternaria.[3] A beneficial side effect of this MCBA listed on some products is "enhanced plant growth", "additional biomass", and "increased yields", although this is most likely attributed to reduced plant stress from mycoparasites.[4]
