Distinct cis-elements in the Asparagus officinalis asparagine synthetase promoter respond to carbohydrate and senescence signals

The Asparagus officinalis L. asparagine (Asn) synthetase (AS) promoter was analysed for elements responding to carbohydrate and senescence signals. Transgenic Arabidopsis thaliana L. plants containing deletion constructs of the –1958 bp AS promoter linked to the β-glucuronidase (GUS) reporter gene (AS::GUS) were analysed by measuring GUS specific activity. Inclusion of sucrose (Suc), glucose (Glc) or fructose (Fru) in plant media repressed levels of GUS activity in –1958AS::GUS plants, regardless of the light environment, with increases in GUS found 1 d after incubation on Suc-lacking media. Hexokinase is likely to be involved in the signal pathway, as Suc, Glc, Fru, 2-deoxy-d-glucose and mannose were more effective repressors than 3-O-methylglucose, and the hexokinase inhibitor mannoheptulose reduced repression. Plants containing AS::GUS constructs with deletions that reduced the promoter to less than –405 bp did not show low sugar induction. AS::GUS activity was significantly higher in excised leaves induced to senesce by dark storage for 24 h, compared to fresh leaves, for lines containing at least –640 bp of the AS promoter but not those with –523 bp or smaller promoter fragments. Fusion of the –640 to –523 bp region to a –381AS::GUS construct generated a promoter that retained senescence induction but lacked low sugar induction. Alignment of this region to the 33-bp senescence-related sequence of the Arabidopsis and Brassica napus L. SAG12 promoters identified the sequence TTGCACG as being conserved in all the promoters, and which may be an important senescence-responsive element.

Editorial

This article presents information on the September 2005 issue of the "Australian Journal of Communication." The papers by Dunn and Churchman in this issue of the journal were delivered at the very successful Annual Conference of the Australian and New Zealand Communication Association, hosted by Colleen Mills at the University of Canterbury, Christchurch, New Zealand, in July 2005. Dunn's presidential address, on the importance of maintaining public broadcasting, is based on her longterm work at the Australian Broadcasting Commission and her current research at the University of Sydney. Many of the other papers in this issue are related to politics and the media in Australia and New Zealand. Cover discusses how the processes of digitisation and a user-based taste for interactivity have far-reaching broadcast television. In her paper, van Vuuren compares the policy and regulation, practice, and theoretical development of the community broadcasting and community information and communication technology (lCT) sectors in Australia, arguing that the ICT sector can benefit from a knowledge of the way in which the older community broadcasting sector has demonstrated an ability to deliver its services with very limited government support.

Sourcing the news: Teaching journalism students different approaches to sourcing practices

The experiences of a group of Australian university journalism students from diverse backgrounds are explored as they become involved in producing five editions of a new newspaper for the isolated community of Blackall in the Queensland Outback, 1500km north-west of Sydney. During this learning experience, non-traditional journalistic sourcing methods were trialled. This paper documents the exercise, compares the alternative methods with existing practices identified in the literature, and examines the effects and consequences of the exercise.

Explaining point variability in the eastern Victoria river region, northern territory

This paper constructs a reduction sequence model for north Australian points from the eastern Victoria River region, and identifies a single continuum linking unifacial and bifacial point forms, with some divergence from this single reduction trajectory dependent upon artefact size. Chronological changes in reduction intensity between 5,000BP and the present are found to coincide with typological variation in points as well as changing emphasis on the extendibility of point reduction. It is suggested that changes in the extendibility of point reduction can be linked to intensified ENSO-driven climatic variability in the late Holocene that likely increased economic risk and warranted a substantial technological response, including the use of retouched toolkits with potential for longer use-lives.

A bayesian artificial neural network method to characterise laminar defects using dynamic measurements

This paper reports on the development of an artificial neural network (ANN) method to detect laminar defects following the pattern matching approach utilizing dynamic measurement. Although structural health monitoring (SHM) using ANN has attracted much attention in the last decade, the problem of how to select the optimal class of ANN models has not been investigated in great depth. It turns out that the lack of a rigorous ANN design methodology is one of the main reasons for the delay in the successful application of the promising technique in SHM. In this paper, a Bayesian method is applied in the selection of the optimal class of ANN models for a given set of input/target training data. The ANN design method is demonstrated for the case of the detection and characterisation of laminar defects in carbon fibre-reinforced beams using flexural vibration data for beams with and without non-symmetric delamination damage.
