    Abstract The lucerne seed web moth or etiella moth, Etiella behrii (Zeller) (Lepidoptera: Pyralidae: Phycitinae: Phycitini) has been recorded as adults and larvae across mainland Australia on leguminous plants. Suitable host plants occur in Tasmania but detections are restricted to adults, mostly in one long-term light trap. A combination of methods is used to determine whether this pest is a non-breeding vagrant, a breeding migrant or resident in Tasmania. A degree-day development model for E. behrii showed that warmer source areas outside Tasmania better explained flight seasonality observed by light trapping in Tasmania than local source areas. Pest records of 119 Lepidoptera associated with Tasmanian Medicago plants do not include Etiella. The absence of records of larvae, the coincidence of adults with migratory insects and northerly airflows, flight seasonality and a requirement for a six month non-developmental period in the cool season indicate that E. behrii migrates to Tasmania where any breeding is below detection although two generations seem possible based on thermal requirements. The results provide another example of a pest that fails to establish, even ephemerally, in Tasmania despite repeated migration from mainland Australia. The precise impediments to seasonal establishment of E. behrii remain unclear but this would most likely occur in north-west or north-east Tasmania, which receive most migratory moths. E. behrii is one of a suite of native Australian pests that may extend its breeding range to Tasmania with global warming. Climate matching models are prone to error if they assume E. behrii is resident in Tasmania.

    Abstract Root growth in Arabidopsis is inhibited by exogenous auxin-amino acid conjugates, and mutants resistant to one such conjugate [indole-3-acetic acid (IAA)-Ala] map to a gene (AtIAR1) that is a member of a metal transporter family. Here, we test the hypothesis that AtIAR1 controls the hydrolysis of stored conjugated auxin to free auxin through zinc transport. AtIAR1 complements a yeast mutant sensitive to zinc, but not manganese- or iron-sensitive mutants, and the transporter is predicted to be localized to the endoplasmic reticulum/Golgi in plants. A previously identified Atiar1 mutant and a non-expressed T-DNA mutant both exhibit altered auxin metabolism, including decreased IAA-glucose conjugate levels in zinc-deficient conditions and insensitivity to the growth effect of exogenous IAA-Ala conjugates. At a high concentration of zinc, wild-type plants show a novel enhanced response to root growth inhibition by exogenous IAA-Ala which is disrupted in both Atiar1 mutants. Furthermore, both Atiar1 mutants show changes in auxin-related phenotypes, including lateral root density and hypocotyl length. The findings therefore suggest a role for AtIAR1 in controlling zinc release from the secretory system, where zinc homeostasis plays a key role in regulation of auxin metabolism and plant growth regulation.

    Abstract From Australia, three new schizopterid genera are described for six new species. The three new genera and Pachyplagioides Gross, 1951 share a declivent head with well-developed internal postocciptal region and a 3-segmented labium with bulbous base. The new genera and species are Parvodeceptor infrequens gen. n., sp. n., Dextritubus cucullatus gen. n., sp. n., D. acucullatus gen. n., sp. n., D. nubis gen. n., sp. n., Carinatala septentrionalis gen. n., sp. n. and C. meridiana gen. n., sp. n. Their description brings to near completion the known generic diversity of Australian Schizopteridae. Parvodeceptor has superficially hypselsomatine facies and may have affinity with the African Humpatanannus Wygodzinsky 1950. Dextritubus has accessory male genitalia reminiscent of Semangananus Stys, 1974 and Vilhenannus Wygodzinsky, 1950. Carinatala has dentate male fore and mid claws, not previously recorded in the family, and an unusual inflatable, spiculate vesica reminiscent of Dundonannus Wygodzinsky 1950. The retention of the internal postocciptal region in several schizopterid genera and lack of its correlation with declivent versus porrect head condition is outlined.

    Abstract Adults but not nymphs of green mirid, Creontiades dilutus (Stål) (Hemiptera: Miridae) are sometimes detected in Tasmania. The species has been recorded, as adults at least, from a wide range of habitats, localities and plants in mainland Australia and suitable host plants occur in Tasmania. Most Tasmanian detections of C. dilutus have been in a long-term light trap and coincide with movements of known long-distance migratory insects and airflows favourable for migration across Bass Strait. In contrast adults and juveniles of the potato bug Closterotomus norwegicus (Gmelin) (Hemiptera: Miridae) are collected regularly in crops for which details are given. A published degree-day development model for C. dilutus was used to identify several impediments to fecundity, egg and juvenile survival and adult maturation such that even ephemeral seasonal establishment is highly unlikely. The absence of juveniles, coincidence of adults with migratory insects and northerly airflows and modelled obstacles to breeding in combination indicate that C. dilutus migrates to Tasmania. The results provide another example of a pest that fails to establish, even ephemerally, in Tasmania despite repeated migration from mainland Australia. Publications stating that the distribution of C. dilutus includes Tasmania are based only on captures of migratory adults. Climate matching models are prone to error if they assume C. dilutus is resident in Tasmania.

    Abstract The range of colours of many flowers and fruits is largely due to variations in the types of anthocyanins produced. The degree of hydroxylation on the B-ring affects the hue of these pigments, causing a shift from the orange end of the visible spectrum to the blue end. Besides colour, this modification can also affect other properties of anthocyanins, including the ability to protect the plant against different stresses or, when included in the human diet, to provide benefits for disease prevention. The level of hydroxylation of the B-ring is determined by the activity of two key hydroxylases, F3′H and F3′5′H, and by the substrate preference of DFR, an enzyme acting downstream in the biosynthetic pathway. We show that, in tomato, a strategy based on fruit-specific engineering of three regulatory genes (AmDel, AmRos1, AtMYB12) and a single biosynthetic gene (AmDFR), together with the availability of a specific mutation (f3′5′h), results in the generation of three different varieties producing high levels of anthocyanins with different levels of hydroxylation. These tomatoes show distinctive colours and mimic the classes of anthocyanins found in natural berries, thus providing unique near-isogenic material for different studies.

    Abstract The most abundant phenolic compound in Solanaceous plants is chlorogenic acid (CGA), which possesses protective properties such as antimicrobial and antioxidant activities. These properties are particularly relevant when plants are under adverse conditions, such as pathogen attack, excess light, or extreme temperatures that cause oxidative stress. Additionally, CGA has been shown to absorb UV-B light. In tomato and potato, CGA is mainly produced through the HQT pathway mediated by the enzyme hydroxycinnamoyl-CoA:quinate hydroxycinnamoyl transferase. However, the absence of natural or induced mutants of this gene has made it unclear whether other pathways contribute to CGA production and accumulation. To address this question, we used CRISPR technology to generate multiple knock-out mutant lines in the tomato HQT gene. The resulting
