Dr Lee Hickey (right) inspecting the barley drought-tolerance experiment with Landmark agronomist Paul McIntosh... "In the work, it was found that even tiny amounts of extra water during a terminal drought can make an extraordinary difference to yield," Dr Hickey says... Dr Hickey believes the work to date shows that the problem of out-of-reach soil moisture is a factor in many cropping systems and environments...

Molecular breeding tools are being developed to tap the adaptive diversity of lupins' wild relatives.. "Breeders recall a story about a 'lupine dinner' held in Hamburg in 1918 (by the Association for Applied Botany) that captures the breadth of lupin's versatility and the reason that Germany spearheaded efforts to domesticate lupins," Dr Nelson says. ".. WA today dominates world production of commercial lupins...

New pathotype virulent to the Yr17 resistance gene identified in two crops.. A new pathotype of stripe rust showing potential resistance to the Yr17 resistance gene has put a question mark over all varieties depending on that gene - including some, such as Ventura, which showed promise as a replacement for the popular, but highly susceptible, H45 variety... [Photo (left) by Brad Collis: Dr Harbans Bariana is working on the development of early plant resistance in the ongoing fight against stripe rust.] "Previous experience suggests that when a pathotype overcomes a resistant gene present in a large number of varieties, it has an advantage and can spread quite rapidly, so it could become more dominant," Dr Wellings says...

There is simply nothing in the domesticated gene pool that can provide in-between flowering times... During 2014, a breakthrough was made in Dr Nelson's laboratory by a 22-year-old GRDC undergraduate honours student, Candy Taylor, who at the time was completing the fourth year of a genetics and breeding undergraduate course at the University of WA... "In early-flowering plants that do not require vernalisation to flower, the FTc1 (flowering-time) gene was expressed at high levels at all times and throughout the plant," Ms Taylor says...

The CSIRO researchers believed that the protein behaved differently in the GM peas than it did in beans where it naturally occurs, and that this was the reason it triggered an immune response in mice... Research results from the Medical University of Vienna recently showed only minor differences in the immune response of mice fed several varieties of beans, non-GM peas and the GM peas... The researchers concluded that the immune response in mice was the same irrespective of whether the inhibitor came from beans, where it naturally occurs, or from peas genetically modified to express the inhibitor...

Frost is a severe dehydrative stress and a significant problem for Australian agriculture, causing annual yield losses estimated at $33 million in South Australia and Victoria... Dehydrins are a group of plant proteins involved in tolerance to cold and drought stress... Some of the genes code for proteins that can act as master-switches which turn on other genes and regulate plant development and metabolism...

Sclerotinia stem rot and blackleg are the two major disease constraints to canola production in Australia... After identifying the genes, they will be functionally analysed by mutation (or silencing) and their role in disease will be determined... A link to more recent research can be found at http://www.botany.unimelb.edu.au/blackleg/index.html..

The causal fungus, Leptosphaeria maculans , produces a toxin, sirodesmin, a virulence factor that contributes to cankering of canola stems... Crop diseases are an important constraint to agriculture people with this expertise will become more valuable to the grains industry... The fungus, L. maculans , produces a toxin, sirodesmin, a virulence factor that contributes to cankering of canola stems, the yield-limiting symptom of blackleg...
