Consumers of whole foods, such as fruits, demand consistent high quality and seek varieties with enhanced health properties, convenience or novel taste. We have raised the polyphenolic content of apple by genetic engineering of the anthocyanin pathway using the apple transcription factor MYB10. These apples have very high concentrations of foliar, flower and fruit anthocyanins, especially in the fruit peel.

During climacteric fruit ripening, autocatalytic (Type II) ethylene production initiates a transcriptional cascade that controls the production of many important fruit quality traits including flavour production and softening. The last step in ethylene biosynthesis is the conversion of 1-aminocyclopropane-1-carboxylic acid (ACC) to ethylene by the enzyme ACC oxidase (ACO). Ten independent kiwifruit (Actinidia chinensis) lines were generated targeting suppression of fruit ripening-related ACO genes and the fruit from one of these lines (TK2) did not produce detectable levels of climacteric ethylene.

Article Synopsis
  • HTLL treatment on the 35S:PAP1 Arabidopsis thaliana leads to a reversible decrease in red color, indicating the involvement of other regulators in anthocyanin production besides the PAP1 gene.
  • Various analytical methods revealed changes in anthocyanin levels and gene expression, showing that certain anthocyanins were reduced while others increased, pointing to a degradation process rather than production.
  • Gene expression analysis after HTLL treatment showed a down-regulation of anthocyanin biosynthesis genes and an increase in potential repressors, highlighting HTLL as a useful tool for studying anthocyanin breakdown and the genes that control it environmentally.

We investigated the effects of root-zone temperature on bud break, flowering, shoot growth and gas exchange of potted mature apple (Malus domestica (Borkh.)) trees with undisturbed roots. Soil respiration was also determined.

Pentachlorophenol (PCP) is a persistent organic pollutant (POP) previously used as a timber treatment chemical to prevent sap stain and wood rot. Commonly used in wood treatment industries for the last 50 years, there are now many sites worldwide that are contaminated with PCP. Although persistent, PCP is a mobile contaminant and therefore has a propensity to leach and contaminate surrounding environments.
