A large cracticine passerine (Aves, Artamidae, Cracticinae) from the Early Miocene, St Bathans Fauna of New ZealandNARA Subscribed
A large fossil passerine (Aves, Artamidae, Cracticinae, Miostrepera canora gen. et sp. nov.), of Early Miocene (19–16 Ma) age, is described based on a proximal and a distal humerus from the lower Bannockburn Formation near St Bathans in Otago, New Zealand. Referred material includes a previously reported scapula and, tentatively so, a distal tibiotarsus. This taxon is the largest passerine in the St Bathans Fauna, in which the...
Identification of genetic loci in lettuce mediating quantitative resistance to fungal pathogensNARA Subscribed
Key message We demonstrate genetic variation for quantitative resistance against important fungal pathogens in lettuce and its wild relatives, map loci conferring resistance and predict key molecular mechanisms using transcriptome profiling. Abstract Lactuca sativa L. (lettuce) is an important leafy vegetable crop grown and consumed globally. Chemicals are routinely used to control major pathogens, including the causal agents...
Two new neoavian taxa with contrasting palaeobiogeographical implications from the early Miocene St Bathans Fauna, New ZealandNARA Subscribed
Two new neoavian landbirds are reported from the early Miocene St Bathans Fauna from New Zealand. Aegotheles zealandivetus sp. nov. is described from several bones, among which, notably, the tarsometatarsus shows more similarity to New Guinean taxa than to Australian—New Zealand species. Zealandornis relictus gen. et sp. nov. is described from a distal end of a humerus and placed in the new family Zealandornithidae, tentativel...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
X-ray tomography of cryopreserved human prostate cancer cells: mitochondrial targeting by an organoiridium photosensitiserNARA Subscribed
The organoiridium complex Ir[(C,N) 2 (O,O)] ( 1 ) where C, N = 1-phenylisoquinoline and O,O = 2,2,6,6-tetramethyl-3,5-heptanedionate is a promising photosensitiser for Photo-Dynamic Therapy (PDT). 1 is not toxic to cells in the dark. However, irradiation of the compound with one-photon blue or two-photon red light generates high levels of singlet oxygen ( 1 O 2 ) (in Zhang et al. Angew Chem Int Ed Engl 56 (47):14898-14902 10.1...
Assembly and characterisation of a unique onion diversity set identifies resistance to Fusarium basal rot and improved seedling vigourNARA Subscribed
Key message A unique, global onion diversity set was assembled, genotyped and phenotyped for beneficial traits. Accessions with strong basal rot resistance and increased seedling vigour were identified along with associated markers. Abstract Conserving biodiversity is critical for safeguarding future crop production. Onion ( Allium cepa L.) is a globally important crop with a very large (16 Gb per 1C) genome which has not been...
Lettuce discolouration is a key post-harvest trait. The major enzyme controlling oxidative discolouration has long been considered to be polyphenol oxidase (PPO) however, levels of PPO and subsequent development of discolouration symptoms have not always correlated. The predominance of a latent state of the enzyme in plant tissues combined with substrate activation and contemporaneous suicide inactivation mechanisms are consid...
Puritz et al . provide a review of several RAD seq methodological approaches in response to our ‘Population Genomic Data Analysis’ workshop (Sept 2013) review (Andrews & Luikart 2014). We agree with Puritz et al . on the importance for researchers to thoroughly understand RADseq library preparation and data analysis when choosing an approach for answering their research questions. Some of us are currently using multiple RAD se...
Summary Much research into food‐borne human pathogens has focused on transmission from foods of animal origin. However, recent investigations have identified fruits and vegetables are the source of many disease outbreaks. Now believed to be a much larger contributor to produce‐associated outbreaks than previously reported, norovirus outbreaks are commonly caused by contamination of foods from hands of infected workers. Althoug...
