Molecular characterization of nematode fauna associated with the rhizosphere of jamun (Syzygium cumini L.) trees from IARI, New Delhi, India

Abstract

Jamun is an important fruit tree found in many tropical and subtropical regions of the world. It is one of the key indigenous minor fruits of commercial value and also known for its timber and ornamental use. There are very few attempts to characterize the nematode biodiversity associated with Jamun trees. In the present study, molecular approach using DNA markers like ITS (Internal transcribed spacer) rDNA, D2-D3 expansion segments of 28S rDNA are used for identification of nematodes associated with Jamun trees in IARI, New Delhi. Predominant nematodes found are Paralongidorus spp, Discolaimus spp, Discolaimoides spp, Paractinolaimus spp, Ecumenicus spp, Tylenchorhynchus spp, Rotylenchulus spp and Hemicriconemoide spp.
