Insight into Plant-Fungal interactions through Secretome analysis

Kahaduwaarachchi, T.M.; Ariyawansa, K.G.S.U. (2019)

Plants possess the ability to distinguish between beneficial and harmful organisms entering the plant from the external environment, and respond accordingly. Effectors are specific elicitor proteins secreted by pathogenic ...
Biocontrol potential of endophytic fungi associated with weedy and wild rice species in Sri Lanka

De Silva, Y.; Ariyawansa, K.G.S.U. (2018)

Plant fungal endophytes are known to influence the ecology and fitness of host plants while enhancing their resistance against biotic and abiotic stress conditions. Fungal endophytes, amidst their other uses in agriculture, ...
Sensing and signalling intercalary growth in Epichloëendophytes: A transcriptomics approach to mechanosensing.

Although fungal hyphae normally extend at apical tips, exceptions to polar growth characterise the ecology of many important species. We are investigating the physiology of intercalary growth in Epichloëfestucae, a ...
Mechanical stress initiates intercalary growth in Epichloë fungal symbionts of grasses.

Ariyawansa, K.G.S.U.; Bradshaw, Rosie E.; Gow, Neil A.R.; Read, Nick D.; Johnson, Richard D.; Harland, Duane P.; Voisey, Christine R. (2015)

Colonization of aerial grass tissues by seed-transmitted Epichloëendo-symbionts initially occurs through ramification of hyphal tips between cells of the host shoot apical meristem (SAM). Uniquely, when hyphae in the SAM ...
Investigating the biocontrol and plant growth promotion potential of fungal endophytes

Devabandu, S.I.; Ariyawansa, K.G.S.U. (2019)

Previous studies have amply demonstrated the potential of fungal endophytes to protect host plants from pests and diseases, while promoting plant growth via different mechanisms. Nevertheless, these potential roles have ...
Mechanical stress initiates intercalary growth in Epichloëfungal symbionts of grasses.

Ariyawansa, K.G.S.U.; Bradshaw, Rosie E.; Gow, Neil A.R.; Read, Nick D; Johnson, Richard D.; Harland, Duane P.; Voisey, Christine R. (2014)

Colonization of aerial grass tissues by seed-transmitted Epichloëendo-symbionts initially occurs through ramification of hyphal tips between cells of the host shoot apical meristem (SAM). Uniquely, when hyphae in the SAM ...

Epichloëfestucae is an agronomically-important endophytic fungus that grows symbiotically within the intercellular spaces of temperate grass species such as Loliumperenne and L. arundinaceum. Colonization of host seedlings ...
Efficient targeted mutagenesis in Epichloë festucae using a split marker system

Rahnama, M.; Forester, N.; Ariyawansa, K.G.S.U.; Voisey, C.R.; Johnson, L.J.; Johnson, R.D.; Fleetwood, D.J. (2017)

A split-marker system for targeted gene deletion was developed for the model grass endophytic fungus Epichloë festucae. Compared to the conventional system that yields up to 25% homologous recombinants, the method resulted ...
Combined Zr and Y phosphate coatings reinforced with chemically anchored B2O3 for the oxidation inhibition of carbon fiber

Ratnayake, S.P.; Purasinhala, K.; Sandaruwan, C.; De Silva, Y. Madhavi; Mantilaka, M.M.M.G.P.G.; Priyadarshana, G.; Amaratunga, G.A.J.; de Silva, K.M. Nalin (Elsevier, 2021)

Abstract The use of carbon fiber-based composites in high-temperature environments has been hindered due to the inferior oxidation resistance of standard carbon fiber. Protective coatings comprised of refractory ceramics ...
Industrial and environmental significance of photonic zirconia nanoflakes: Influence of boron doping on structure and band states

Ratnayake, S.P.; Sandaruwan, C.; Mantilaka, M.M.M.G.P.G.; De Silva, N.; Dahanayake, D.; Wanninayake, U.K; Bandara, W.R.L.N.; Santhoshkuma, S.; Murugan, E.; Amaratunga, G.A.J.; de Silva, K.M. Nalin (Elsevier, 2021)

Abstract A unique zirconia nanomorphology possessing an enhanced photocatalytic efficiency was developed utilizing a convenient single-sol synthesis process which involved in-situ doping of zirconia by boron. The boron-doped ...
Microwave assisted accelerated fluoride adsorption by porous nanohydroxyapatite

Wimalasiri, A.K.D.V.K; Fernando, M.S.; Williams, Gareth R.; Dissanayake, D.P.; de Silva, K.M. Nalin; de Silva, Rohini M. (Materials Chemistry and Physics, 2021)

Abstract Fluoride pollution of water is a matter of concern in many countries due to its association with chronic kidney failure. Therefore, it is important to develop fast and efficient methods for fluoride removal from ...
