| Summary: | Trichoderma species form endophytic associations
with plant roots and may provide a range of benefits to their
hosts. However, few studies have systematically examined the
diversity of Trichoderma species associated with plant roots in
tropical regions. During the evaluation of Trichoderma isolates
for use as biocontrol agents, root samples were collected
from more than 58 genera in 35 plant families from a range of
habitats in Malaysian Borneo. Trichoderma species were isolated
from surface-sterilised roots and identified following
analysis of partial translation elongation factor-1α (tef1) sequences.
Species present included Trichoderma
afroharzianum, Trichoderma asperelloides, Trichoderma
asperellum, Trichoderma guizhouense, Trichoderma reesei,
Trichoderma strigosum and Trichoderma virens.
Trichoderma asperellum/T. asperelloides, Trichoderma
harzianum s.l. and T. virens were the most frequently isolated
taxa. tef1 sequence data supported the recognition of
undescribed species related to the T. harzianum complex.
The results suggest that tropical plants may be a useful source
of novel root-associated Trichoderma for biotechnological
applications. |
