Characterisation of a putative dothistromin biosynthetic cluster : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Molecular Biology at Massey University, Palmerston North, New Zealand [PDF]

, 1999
The fungus Dothistroma pini is a key pathogen in New Zealand (and international) softwood plantations, most notably P. radiata. The mycotoxin dothistromin produced by this saprophytic fungus is believed to play a major role in its pathogenesis ...

Cylindrocyclophane Biosynthesis Involves Functionalization of an Unactivated Carbon Center [PDF]

, 2012
The cylindrocyclophanes are a family of natural products that share a remarkable paracyclophane carbon scaffold. Using genome sequencing and bioinformatic analyses, we have discovered a biosynthetic gene cluster involved in the assembly of ...

OsMT2b Regulates Pollen Development and ROS Homeostasis in a Photoperiod‐Dependent Manner

Plant Biotechnology Journal, EarlyView.
ABSTRACT Reactive oxygen species (ROS) are signalling molecules that promote programmed cell death in animal and plant systems. However, their role in rice (Oryza sativa L.) anther development is unclear. In this study, we show that lower transcript levels of the metallothionein gene OsMT2b in japonica rice plants obtained by RNA interference (RNAi ...

Heterologous Production of Fungal Maleidrides Reveals the Cryptic Cyclization Involved in their Biosynthesis [PDF]

, 2016
Fungal maleidrides are an important family of bioactive secondary metabolites that consist of 7, 8, or 9-membered carbocycles with one or two fused maleic anhydride moieties.

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

Plant Biotechnology Journal, EarlyView.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Multi‐Omics Insights Into Anthraquinone Biosynthesis in Rheum tanguticum

Plant Biotechnology Journal, EarlyView.
ABSTRACT Rheum tanguticum is renowned for its medicinal properties, including purgative, anti‐inflammatory and hepatoprotective effects, primarily attributed to anthraquinones (AQs). However, the molecular mechanisms of AQs biosynthesis have largely been hindered by insufficient genomic resources and functional genomics investigations.

The Stereochemistry of Complex Polyketide Biosynthesis by Modular Polyketide Synthases

Molecules, 2011
Polyketides are a diverse class of medically important natural products whose biosynthesis is catalysed by polyketide synthases (PKSs), in a fashion highly analogous to fatty acid biosynthesis. In modular PKSs, the polyketide chain is assembled by the successive condensation of activated carboxylic acid-derived units, where chain extension occurs with ...
