How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Austropuccinia psidii, (Basidiomycota; Pucciniales) (formerly Puccinia psidii), commonly known as Myrtle rust, is a fungal pathogen that has quickly become a global threat. The physiological infection cycle of A. psidii is comprised of distinct steps that are potential targets for host defense strategies or human-induced control methods. While gene...
In the version of this Comment originally published, the last year on the axis of Fig. 1c read 3000; it should have read 2100. This has now been corrected.
Bitcoin is a power-hungry cryptocurrency that is increasingly used as an investment and payment system. Here we show that projected Bitcoin usage, should it follow the rate of adoption of other broadly adopted technologies, could alone produce enough CO2 emissions to push warming above 2 °C within less than three decades.
An invasive fungal rust pathogen, Austropuccinia psidii, is a main component contributing to the decline of the critically endangered Hawaiian Eugenia tree (Eugenia koolauensis). Once common on the islands of Oahu and Molokai, E. koolauensis is now limited to 11 populations with a total of ~274 mature individuals on the island of Oahu. Hundreds of asymptomatic fungal species live within the E. koolauensis leaf tissue, and recent studies imply the composition of these foliar fungal communities can affect the severity of pathogens such as A. psidii. Using molecular and culture-based methods, our study hopes to characterize the fungal community and identify foliar fungal species that inhibit the growth of A. psidii on Eugenia trees.
