Margvelashvili,John Andrewartha,Clothilde Langlais,Matthew P. Adams,Nagur Cherukuru,Malin S.M. Gustafsson,Scott Hadley,Peter J. Ralph,Uwe Rosebrock,Thomas Schroeder,Leonardo Laiolo,Daniel P. Harrison,Andrew D. L. Steven +22 more
TL;DR: The suite of coupled models is referred to as the CSIRO Environmental Modelling Suite (EMS) and has been applied at tens of locations around the Australian continent as mentioned in this paper, where the underwater light field is simulated by a spectrally resolved optical model that calculates vertical light attenuation from the scattering and absorption of 20+ optically active constituents.
Journal ArticleDOI
ChloroMitoSSRDB 2.00: more genomes, more repeats, unifying SSRs search patterns and on-the-fly repeat detection.
Gaurav Sablok,G. V. Padma Raju,Suresh B. Mudunuri,Ratna Prabha,Dhananjaya P. Singh,Vesselin Baev,Galina Yahubyan,Peter J. Ralph,Nicola La Porta +8 more
TL;DR: The present research has updated ChloroMitoSSRDB by systematically analyzing and adding additional 191 chloroplast and 2102 mitochondrial genomes and integrated and made available several in silico SSRs mining tools through a unified web-portal for insilico repeat mining for assembled organelle genomes and from next generation sequencing reads.
Journal ArticleDOI
Low oxygen affects photophysiology and the level of expression of two-carbon metabolism genes in the seagrass Zostera muelleri
Mikael Kim,Kasper Elgetti Brodersen,Milán Szabó,Anthony W. D. Larkum,John A. Raven,John A. Raven,Peter J. Ralph,Mathieu Pernice +7 more
TL;DR: The photophysiological response of Z. muelleri to changing oxygen in water is capable of rapid acclimation and the dynamic modulation of pathways should be considered when assessing seagrass primary production.
Journal ArticleDOI
Metabolic Engineering Strategies in Diatoms Reveal Unique Phenotypes and Genetic Configurations With Implications for Algal Genetics and Synthetic Biology
Jestin George,Tim Kahlke,Raffaela M. Abbriano,Unnikrishnan Kuzhiumparambil,Peter J. Ralph,Michele Fabris,Michele Fabris +6 more
TL;DR: This work engineered the model diatom Phaeodactylum tricornutum to produce the high-value heterologous monoterpenoid geraniol, which, besides applications as fragrance and insect repellent, is a key intermediate of high- value pharmaceuticals, and confirmed the suitability of episomes for synthetic biology applications and identified superior gerAniol-yielding strains following random integration.
Journal ArticleDOI
Molecular physiology reveals ammonium uptake and related gene expression in the seagrass Zostera muelleri
Mathieu Pernice,Sutinee Sinutok,Gaurav Sablok,Audrey S. Commault,Martin Schliep,Peter I. Macreadie,Michael Rasheed,Peter J. Ralph +7 more
TL;DR: It is demonstrated that exposure to a pulse of ammonium in seawater can induce changes in GS gene expression of Z. muelleri, and further correlate these changes in gene expression with 15N-ammonium uptake rate in above- and below-ground tissue.
