Effect of acibenzolar-S-methyl and Saccharomyces cerevisiae on the activation of Eucalyptus defences against rust
(CSIRO Publishing, 2009-01-01)
Tree defence mechanisms against the fungus Puccinia psidii were examined by comparing the activities of defence-related enzymes (chitinase, peroxidase and phenylalanine ammonia-lyase) of two Eucalyptus grandis x E. urophylla ...
Extrafloral nectar fuels ant life in deserts
(Oxford University Press, 2014-11-07)
Interactions mediated by extrafloral nectary (EFN)-bearing plants that reward ants with a sweet liquid secretion are well documented in temperate and tropical habitats. However, their distribution and abundance in deserts ...
Insights into a novel three-partner interaction between ants, coreids (Hemiptera: Coreidae) and extrafloral nectaries: implications for the study of protective mutualisms
(Springer, 2017-08)
Extrafloral nectar of plants and honeydew of hemipterans are the common mediators of facultative interactions that involve ants as a mobile strategy of defence. The outcome of these interactions can vary from mutualistic ...
Single-stranded oligodeoxynucleotides induce plant defence in Arabidopsis thaliana
(Oxford University Press, 2020-09)
Background and AimsSingle-stranded DNA oligodeoxynucleotides (ssODNs) have been shown to elicit immune responses in mammals. In plants, RNA and genomic DNA can activate immunity, although the exact mechanism through which ...
The dual nature of trehalose in citrus canker disease: A virulence factor for Xanthomonas citri subsp. citri and a trigger for plant defence responses
(Oxford University Press, 2015-05)
Xanthomonas citri subsp. citri (Xcc) is a bacterial pathogen that causes citrus canker in susceptible Citrus spp. The Xcc genome contains genes encoding enzymes from three separate pathways of trehalose biosynthesis. ...
Natural history of an ant-plant-butterfly interaction in a Neotropical savanna
(TAYLOR & FRANCIS LTDABINGDON, 2012)
Non-myrmecophilous lepidopteran larvae using plants bearing ant attractants such as extrafloral nectaries are good models for studying morphological and behavioural mechanisms against ant predation. Udranomia spitzi ...
Rapid increase in growth and productivity can aid invasions by a non-native tree
(Oxford University Press, 2018)
Evolution of extrafloral nectaries: adaptive process and selective regime changes from forest to savanna
(WILEY-BLACKWELLHOBOKEN, 2012)
Much effort has been devoted to understanding the function of extrafloral nectaries (EFNs) for antplantherbivore interactions. However, the pattern of evolution of such structures throughout the history of plant lineages ...
