Trichoderma nordicum

Ciri dan struktur

Phylogenetically Trichoderma nordicum is related to T. paratroviride, but the sequence similarities of rpb2 and tef1 -α were 98.15% and 94.43%, respectively. That does not meet the sp ∃!(rpb2 99 ≅ tef1 97) standard for T. paratroviride or other known Trichoderma species. Morphologically, conidiophores of T. paratroviride consisting of a main axis and often distantly-spaced side branches, not re-branching. Conidiophores of T. nordicum are branched in a more complex manner; conidia are larger than those of T. paratroviride.

Habitat dan peran ekologis

China, Beijing, Yu-yuan-tan Park, 43 m (altitude), isolated from soil, 27 October 2016, G.Z. Zhang (Holotype WT 13001), ex-type culture ACCC 39713. Unknown. Growth optimal at 25 °C, slow or limited at 30 °C, absent at 35 °C. Colonies grew fast on PDA, CMD and MEA and slow on SNA. Colony radius after 72 h at 25 °C 67–71 mm on PDA, 68–71 mm on CMD, 51–55 mm on MEA and 21–24 mm on SNA. Aerial mycelia sparse on PDA after 72 h at 25 °C under 12 h photoperiod and conidiation developed within 48 h beginning at the inoculation point and progressed around, grey-white at first and slowly turning green. Diffusing pigment or distinctive odour absent. Aerial mycelia sparse and flocculence on MEA after 72 h at 20 °C under 12 h photoperiod. Conidia developed within 48 h beginning near the colony margin on MEA, grey-white at first and slowly turning green, transparent liquid secreted. Aerial mycelia few on SNA and CMD after 72 h at 25 °C, conidia formed around the inoculation point and in distinct concentric rings after 96 h under 12 h photoperiod on SNA and CMD, diffusing pigment not produced. Conidiophores and branches narrow and flexuous, tending to be regularly verticillate forming a pyramidal structure, each branch terminating in a cruciate whorl of up to five phialides.
