Coastal marine macroalgae are highly diverse and rich in bioactive compounds, though only a few studies have explored their antifungal potential against plant pathogens Sri Lanka. This study investigated the activity of Ulva sp., Gracilaria Sargassum sp. from Thalpe Reef, Galle, Lanka, fungal Lasiodiplodia theobromae, Pseudopestalotiopsis theae, Diaporthe eugeniae. These cause leaf necrosis, chlorosis, blight, respectively, Solanum melongena plants. To evaluate each species, sequential crude...

The diversity of cyanobacteria in Sri Lanka was studied different water reservoirs, paddy fields, brackish and tsunami affected areas using light microcopy, 16S rRNA sequences, followed by phylogenetic analysis. Based on microscopy, 24 genera were identified from environmental samples belonging to the orders Chroococcales, Oscillatoriales, Pleurocapsales Nostocales. In cultures, 33 all five cyanobacterial orders, including Stigonematales. gene sequences their morphology, two isolates up...
Purpose: Solanum melongena L. (brinjal/ eggplant) is a popular vegetable in Sri Lanka. Like many solanaceous crops, brinjal fruits and plants are susceptible to various diseases. The objective of this study was isolate, confirm pathogenicity characterize fungal pathogens causing leaf blight, yellowing necrosis S. selected localities Gampaha district, Research Method: Fungi associated with symptomatic collected from three Lanka, were isolated onto potato dextrose agar their tested on healthy...
The isolation of DNA from biological samples is a crucial step in the process DNA-based molecular assays. In this study, we present simple method to extract and purify genomic different sample types (standard cyanobacteria, cyanobacteria water leaves bamboo plants) which would be suitable for any analyses. method, are lysed by three sequential freezing heating followed enzymatic treatment with lysozyme proteinase K. extraction purification was achieved lysing nuclease inactivating properties...
Marine macroalgae is a promising resource with diverse range of industrial applications. In Sri Lanka, only limited number studies have been conducted to study the morphological plasticity and cryptic diversity marine molecular data available still scarce. This provides evidence for newly identified Ulva sp. collected from Barbarian reef, Beruwala, Lanka. Specimen collection was carried out in September 2018 Beruwala it analysed based on characters rDNA ITS1-5.8S-ITS2 sequences. The specimen...
