Sports give trees a sporting chance

A study of Eucalyptus melliodora at the Australian National University shows that mutations that occur during vegetative growth over a tree's long life can lead to some branches being more pest-resistant than others. In this case, the variation was explained by changes in terpene production. These genetic "sports" might be deleterious if carried by the whole plant, but do give a chance of survival under heavy insect attack.

More than one scribbler

Although a distinctive feature of some Eucalypts, the cause of the "scribbles" on their trunks has until recently been little studied. The Australian Scribbly Gum Moth was thought to be the only species responsible, but thanks to a team of "retired" CSIRO scientists, we now know that at least twelve species of moths can create the phenomenon.

Eucalytpus genome holds potential for new, better forestry crops
The complete genetic sequence (about 640 million DNA base pairs) of Eucalyptus grandis has been published. It took more than 130 researchers four years to complete the project. It's hoped that the information will facilitate the breeding of forestry trees suited to production of wood, paper, biofuels or other bioproducts, or with other desirable characteristics.

Myrtle rust a threat to Eucalypts
This disease attacks a wide variety of plants in the family Myrtaceae. It was first detected in NSW in 2010, but has since been identified in Qld. The extent of the host range is still being investigated, but some eucalypts have been included in the list. For more information on the disease and up-to-date information concerning reporting obligations and quarantine restrictions, visit Biosecurity Queensland, the Myrtle Rust website (NSW Department of Primary Industries), or contact the relevant authority in your state or territory.

Gums should recover from caterpillar outbreak
Agri-Science Queensland has assured residents of the Boonah, Beaudesert, Lockyer Valley and Brisbane/Esk Valley regions that local gum trees attacked by a recent outbreak of caterpillars will recover. The gum leaf skeletoniser (Uraba lugens) can leave trees with a "bronzed" or "scorched" appearence. The large numbers have probably resulted from the weather conditions this winter and spring. Hotter temperatures should see numbers decrease. In the meantime, residents should avoid contact with the caterpillars, which can cause skin irritation.

New discoveries still being made after 250 years
New plants discovered or described by botanists from the Royal Botanic Gardens, Kew in its 250th year include Madagascan relatives of the coffee plant, a South African yam with a reputation as a cancer cure, and two eucalypts from Australia that have potential as ornamentals.
