Wood-decay macro-fungi have been reported
to be a major cause of decline of arid zone trees in the
genera Acacia, Prosopis, Ziziphus and Azadirachta; the
identity of these fungi, however, has not been confirmed
in the state of Rajasthan in northwestern India. Direct
sequencing of PCR amplified ITS regions of rDNA
facilitated molecular identification of 26 isolates into
species in eight genera (Ganoderma, Inonotus,
Phellinus, Ceriporia, Schizophyllum, Phanerochaete,
Pleurotus, Leucoagaricus) and one incompletely characterized
Basidiomycota species. In addition to intraspecific
phenotypic variations in basidiocarp morphology,
Single Nucleotide Polymorphisms (SNPs) were
recorded among isolates of P. pulmonarius, S. commune,
G. lucidum and Ganoderma species. Both SNPs
and insertions/deletions (INDELS) were recorded
amongst Inonotus species. A phylogram based on multiple
sequence alignment delineated all isolates into
separate intra-specific subgroups along with their
GenBank reference sequences with high bootstrap values.
Phellinus repandus, L. meleagris, C. lacerata and
three Inonotus species (I. rickii, I. patouillardii, and I.
porrectus) reported herein are new fungal records from
India.
