Project description:Cost-effective, fibrinolytic agents possessing least or no antigenic properties are much in demand for their prospective use as clot busters in thrombolytic therapy. The present communication explores the potential of 22 endophytic Botryosphaeria species isolated from stem of Aegle marmelos for their fibrinolytic potential. Only nine fungal isolates exhibited proteolytic activity out of which only four possessed plasminogen-independent fibrinolytic activity. The endophytic fungal isolate #1088 AMSTITYEL showed maximum in vitro proteolytic and fibrinolytic activity with a halo formation of 153.86 and 113.04 mm2, respectively. The partially purified protein exhibited a fibrinolytic activity equivalent to 6.51 U/ml of plasmin. SDS-PAGE of the dialysed fraction of #1088 AMSTITYEL resolved into six bands ranging from 26 to 80 kDa. Fibrin zymogram exhibited that a single band of molecular size ~80 KDa possessing the fibrinolytic activity. Furthermore, the bioactive isolate #1088 AMSTITYEL was identified as Lasiodiplodia pseudotheobromae using classical and molecular taxonomic tools.
Project description:Botryosphaeriaceae is an important fungal family that can colonize a wide range of woody hosts including economically important plants and cause serious diseases worldwide. To uncover the virulence variation in Lasiodiplodia theobromae, we sequenced the transcriptome of Las1 in L. theobromae inoculated with the stems of V.vinifera using dual-RNAseq method. We found a lot of expanded genes were induced after inoculated with grapevine compared with the transcriptome of Las1 that was maintained in PDA under the same condition.
